REPRESENTATION Appellant represented by: Disabled American Veterans WITNESSES AT HEARING ON APPEAL The veteran and T.T., a social worker ATTORNEY FOR THE BOARD J.M. Daley, Associate Counsel INTRODUCTION The veteran had service from August 1974 to April 1991. These matters are before the Board of Veterans' Appeals (Board) on appeal from the Department of Veterans Affairs (VA) Regional Office (RO), located in Boise, Idaho. In connection with this appeal the veteran testified at a personal hearing before an RO Hearing Officer in June 1998; a transcript of that hearing is associated with the claims file. The Board notes that during the pendency of this appeal the RO has increased the evaluations assigned to the veteran's cervical, thoracic and lumbar spines, effective December 1, 1996, the date of receipt of her claim for increases. Although each increase represented a grant of benefits, the veteran has not withdrawn her increased rating claims pursuant to 38 C.F.R. 20.204(b), (c) (1999). The United States Court of Appeals for Veterans Claims (known as the United States Court of Veterans Appeals prior to March 1, 1999) (hereinafter, "the Court") has held that a "decision awarding a higher rating, but less than the maximum available 2 benefit ... does not ... abrogate the pending appeal ...... AB v. Brown, 6 Vet. App. 35, 38 (1993). Accordingly, the veteran's increased rating claims continue before the Board. The Board further notes that subsequent to the supplement statements of the case of record, additional pertinent medical evidence has been received. The veteran has submitted a written waiver of her right to have that evidence initially considered by the RO. 38 C.F.R. 20.1304(c) (1999). FINDINGS OF FACT 1. The evidence is in relative equipoise with respect to the question of whether the veteran has an acquired depressive disorder that is related to service-connected disability. 2. The competent and probative evidence demonstrates that degenerative disc disease of the lumbar spine is manifested by a limitation of lumbar spine motion and subjective complaints of pain, productive of no more than moderate disability. 3. The competent and probative evidence demonstrates that degenerative disc disease of the thoracic spine results in subjective complaints of pain and spasm, productive of no more than mild disability. CONCLUSIONS OF LAW 1. All benefit of the doubt being resolved in the veteran's favor, a depressive disorder is proximately due to or the result of service-connected degenerative joint disease of the cervical, lumbar and thoracic spine. 38 U.S.C.A. 5107 (West 1991); 38 C.F.R. 3.303, 3.310 (1999). - 3 - 2. The criteria for an evaluation in excess of 20 percent for service-connected degenerative disc disease of the lumbar spine have not been met. 38 U.S.C.A. 1155, 5107 (West 1991); 38 C.F.R. 4.40, 4.45, 4.59, 4.71a, Diagnostic Code 5293 (1999). 3. The criteria for an evaluation in excess of 10 percent for service-connected degenerative disc disease of the thoracic spine have not been met. 38 U.S.C.A. 1155, 5107 (West 1991); 38 C.F.R. 4.71a, Diagnostic Code 5293 (1999). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS Factual Background The veteran served from August 1974 to April 1991, and was placed by the military on the temporary disability retired list from April to September 1991. She filed a claim for service-connected compensation benefits in April 1991. At that time she provided a list of claimed disorders; neither depression nor any other psychiatric disorder was listed on that initial claim. As a result of the veteran's lengthy service, extensive service medical records are associated with the claims file. Service records beginning in the 1970s reflect the veteran's complaints of neck and back pain. In March 1977, cervical spine and neurologic examinations were stated to be within normal limits. In October 1978, the veteran was examined for complaints to include numbness and aching in both arms. The examiner opined that there was no significant thoracic outlet syndrome and recommended exercises to build up the veteran's tolerance to the job requirement of lifting files and charts. After lifting a box in November 1978, the veteran again complained of back pain. Examination revealed tenderness in the lumbosacral area and a questionable decreased pinprick on the left inner calf, the impression was left sciatica. Such was noted to be resolving later in November. Service records indicate that the veteran was placed on a lifting profile. - 4 - Service records dated in September 1980 show complaints of cervical spine pain. The veteran was evaluated in the mental health clinic in April 1982; the impression was that she should come for help coping effectively with financial issues and issues of child- rearing and "as of now unknown" personal problems. The impression in April 1982 was a situational reaction. The evaluation shows the veteran's complaints of work problems and fear of doing physical harm to her stepson. A May 1982 record shows a diagnosis of low back strain with radiation down the left sciatic nerve. In May 1983, the veteran was treated for cervical radiculitis. Her cervical spine motion was restricted in all planes and examination showed spasm and tenderness. The veteran was seen for daily physical therapy and in June 1983 her pain was noted to be resolving, with only a "slightly limited" range of cervical motion. A service medical record dated in April 1984 indicates that the veteran experienced intermittent paresthesia with complaints of leg weakness. A June 1984 record shows an impression of facet syndrome/sciatica, and other June records indicate the presence of spasm. In July 1985, the veteran complained of muscle spasm of the neck and upper back, from which she had received temporary relief with the use of medications in the past. The impressions were cervical ribs and cervical spine muscle spasm. Consultation in August 1985 was to rule out thoracic outlet syndrome. A thoracic surgery clinic report concludes that the veteran had no objective findings of neurologic or vascular compromise, but that thoracic outlet syndrome could not be ruled out. It was also stated that cervical radiculitis remained a possibility. Electromyography and nerve conduction studies were normal. The assessment by neurosurgery in October 1985 was cervical radiculopathy, etiology unknown. Records reflect that the veteran underwent surgical fusion at C5 to C6 in December 1985. Records dated from April to June 1987 continue to show the veteran's complaints of cervical and back pain. Diagnostic testing conducted in September 1988 showed no evidence of nerve root involvement in the entire spine. The impression in October 1988 was positional numbness, without evidence of consistent neuropathy 5 - by examination or evidence of radiculopathy by diagnostic testing. A record dated in March 1989 indicates that the veteran had "positional" numbness of the left inner arm and "positional" dropping of tools. In May 1989, the veteran experienced an "[e]xacerbation of chronic [low back pain with left sciatica]." Service medical records show that in September 1989, the veteran reported for neurosurgery consultation with complaints of pain and numbness in the left arm, facial numbness on the left side, and constant low back pain. The examiner indicated that the left arm pain and numbness were perhaps related to cervical spondylosis; that the facial numbness was perhaps related to migraines; and that the low back and left leg pain was not currently a major complaint. A February 1990 report shows moderate levoscoliosis of the upper thoracic spine and findings of degenerative disc disease at T4 to T5. In August 1990 the veteran underwent mental status evaluation by a psychologist. That note indicates that the veteran was upset when a physician "would not comply with her request to take charge of her medical care and to orchestrate a comprehensive treatment regimen for her back problems." The veteran later submitted an explanation,, stating that personal stresses led up to the event in question. In August 1990, Minnesota Multiphasic Personality Inventory (MMPI) was accomplished and suggested, in part, that the veteran fit into a pattern of individuals for whom "[h]ypochondriacal adjustment patterns are usually chronic and quite resistant to change" and where "[c]haracterological elements are suggested." Testing was also interpreted to be consistent with individuals who were "often mildly depressed, pessimistic and worried." The conclusion was that testing did not rule out the presence of significant levels of pain or actual physiological disease process, but that significant psychological factors contributed to the veteran's medical presentation and that the veteran was "quite committed to chronic pain and illness as a major factor in her lifestyle and this can be expected to persist." Service medical records include a report of physical evaluation conducted in September 1990. The evaluation report includes the veteran's history of back pain since 1975 or 1976, at which time she injured her back. The veteran specifically - 6 - related a history of persistent pain in the neck, thoracic and lumbar areas. The evaluation report includes note that the veteran underwent cervical diskectomy at the C5 to C6 level in 1985, and that approximately seven months afterwards fell when a chair collapsed, re-injuring her neck. The veteran specifically complained of numbness in the left arm with a loss of grasp, persistent pain in the mid-thoracic region; intermittent lumbar pain; pain radiating to the posterior lateral thigh to the knee; and numbness in the left foot. She was working as a training monitor and complained that she was unable to fulfill all activities due to pain. Examination in September 1990 that in a standing position the veteran's right shoulder, scapula and pelvis were tilted downward as compared to the left. Lumbar flexion was "hands to toes" with 10 degrees extension and 20 degrees lateral bending. There was pain at the lumbosacral junction. Pinprick discrimination was intact and straight leg raising was negative. There was stated to be percussion tenderness in the thoracic and lumbar spine without radicular symptoms demonstrated. X-rays showed scoliosis of the thoracolumbar spine. Computerized tomography (CT) showed no herniated nucleus pulposus at T3 to T5. CT of the lumbar spine revealed no discogenic disease. A bone scan showed findings consistent with minimal mild degenerative processes. The clinical impressions were post cervical diskectomy at C5 to C6 and spinal somatic dysfunction secondary to mild degenerative changes. The examiner noted that there were no demonstrable neurologic deficits. The Standard Form 88 "Report of Medical Examination" dated in September 1990 summarizes mild dextroscoliosis; a full range of back motion; and mildly decreased lateral flexion and rotation of the neck. A report of the Physical Evaluation Board (PEB) shows diagnoses of undifferentiated somataform disorder; no personality disorder diagnosis, borderline and histrionic traits; post-cervical diskectomy at C5 to C6; and spinal somatic dysfunction secondary to mild degenerative changes. An orthopedic surgeon confirmed that the veteran's complaints were in excess of what was expected from the physical findings. The PEB report also notes that the veteran's assessment what that she was unable to safely perform her duties, but that that assessment was "different from her supervisor's assessment...." A February 1991 recommendation - 7 - sheet from the PEB shows a diagnosis of status post cervical diskectomy at C5 to C6 associated with somataform pain disorder with considerable social and industrial impairment. The remarks include note that the veteran's "condition is felt to be more closely related to a somataform disorder as [her] complaints are in excess of what is expected from physical findings. [She] has had extensive workups that have not produced a specific etiology for the degree of pain experienced ... this condition limits [her] ability to perform her duties and renders her unfit for further active duty." In June 1991 the veteran presented for VA evaluation with complaints to include left upper and lower extremity numbness and tingling, and back pain. She stated that her numbness and tingling in the left arm were more frequent, but that her back pain had decreased in frequency. She reported that during aggravation of her back pain it took three to five days to regain her full mobility. The veteran reported that she was unable to reach above her head without difficulty. She stated that her back pain varied and increased and decreased from time to time, with "most of the time it's just a minor ache." Lumbosacral spine films were unremarkable. Thoracic spine films showed only "very minimal" degenerative changes stated to be compatible with the veteran's age. Cervical spine films showed moderate narrowing at C6 and mild narrowing at C6 to C7 with minimal bilateral neuroforaminal narrowing at C6 to C7. Examination of the back revealed good lateral flexion and good rotation without marked increase in paraspinal muscle spasm. The veteran was able to bend forward and touch her toes without difficulty. The examiner noted that the veteran described all of her symptoms in elaborate detail and that there was no evidence of psychosocial adjustment problems. The June 1991 VA examination diagnoses were, in pertinent part, thoracic outlet syndrome and status post herniated cervical intervertebral disk surgery with good function on examination and very slight limitation. In a rating decision dated in September 1991, the RO established service connection and assigned disability evaluations as follows: degenerative disc disease of the cervical spine, diskectomy with fusion at C5 to C6 and a history of thoracic outlet - 8 - syndrome, evaluated as 20 percent disabling; degenerative joint disease and claimed arthritis of the thoracic and lumbar spine, evaluated as 10 percent disabling; a gastric ulcer with dyspepsia, evaluated as 10 percent disabling- bronchitis, evaluated as 10 percent disabling; and, for the following, each assigned a zero percent evaluation: residuals of left hip abductor muscle strain; left wrist scars from ganglion cyst excision; third and fourth metatarsal fractures of the right foot; residuals of injury to the left foot; right kidney nephrolithiasis; euthyroid nodular goiter; and chronic sinusitis. All disability evaluations and service connection grants were made effective April 10, 199 1. In November 1991, the veteran continued to complain of neck and mid-thoracic and lumbar pain, with left upper extremity numbness. In March and April 1992, the veteran complained of continued pain in the back, specifically the upper thoracic area, and also complained of left upper extremity numbness. One April 1992 note includes the statement that the veteran was "fixated on this," referring to her mid-thoracic back pain of uncertain etiology. The examining physician noted that such had not previously been the veteran's main focus of attention and noted questionable functional overlay. Electromyography/nerve conduction studies completed in March/April 1992 were reported to be normal and interpreted as showing no evidence of radiculopathy. The veteran was seen at the pain clinic for chronic pain complaints from May to July 1992. A report of an MRI dated in October 1992 indicates a loss of cervical lordosis and fusion at C5 to C6; osteophyte formation at C4 to C5 and C6 to C7, with moderate thecal sac effacement but without evidence of spinal cord impingement; and mild neuroforaminal narrowing; and normal lumbar spine findings. In August 1993 the veteran presented for treatment at a military facility with a history of having wrenched her back lifting groceries. She complained of mid-back pain with some radiation to her left leg and upper back. Examination revealed left paraspinous tenderness without sciatic nerve tenderness. Straight leg raising was - 9 - negative and reflexes and strength were equal. The impression was mechanical low back pain. VA records dated in August 1993 reflect that the veteran was seen at the pain clinic; she complained that she was no longer able to handle her job. Other August records include note of psychiatric triage, at which time the veteran expressed frustration with VA relevant to her complaints of back pain and need for medication. A record dated in September 1993 indicates that range of motion of the veteran's neck was limited in all directions by pain; use of a TENS unit was prescribed. One entry notes that the veteran had probable fascia tightening with excessive muscular tightness in the back and little pain tolerance. The examining physician noted that the veteran did not appear motivated to decrease the pain level. Another September record reflects the use of antidepressant trial medication and notes the veteran's depressed mood and chronic pain. A VA outpatient record dated in October 1993 notes an assessment of chronic unrelenting thoracic spine pain. X-rays showed mild degenerative changes compatible with the veteran's age and minimal scoliosis stated to "may well be positional." In an October 1993 note, the veteran asked her physician if she should continue working in her labor intensive job because of her excruciating thoracic pain. Another October record indicates a past medical history of cervical and thoracic degenerative joint disease with chronic pain, and depression. A report of x-ray of the cervical spine dated in December 1993 indicates "complete obliteration of the C5 to C6 disc space and significant narrowing of the disc spaces at C6 to C7 and C4 to C5" and mild narrowing between C4 and C7 bilaterally at multiple levels. VA outpatient records dated in May 1994 indicate that the veteran complained of tenderness to touch of her upper back, shoulders and neck, and of intermittent numbness and tingling in her hands. The report of a CT scan conducted in September 1994 indicates that the veteran "does appear to have significant lesion at T3-4 which causes definite cord distortion." The report also notes a scoliotic curvature of the upper thoracic spine - 10 - with the cord somewhat tethered to the inside of this curvature." A cervical spine CT showed an "[a]pparently congenital narrow central canal with less than normal CSF spaces ... [c]entral canal stenosis is the most prominent feature at all levels scanned ... somewhat accentuated by the degenerative spurring...." An October 1994 treatment note shows an assessment of chronic pain. In February 1995, the veteran's claim was remanded to the RO for further development, in particular, contemporary examination evidence. VA examinations of the veteran's spine were conducted in May, June and July 1995. The May 1995 report of VA neurologic evaluation reflects that sensation was normal in the arms and legs. Muscle strength testing was fully intact, without focal muscle wasting, and the veteran's gait, balance and coordination appeared normal. The June 1995 report of a VA spine examination notes the veteran's complaints relevant to her neck, hands, forearms, and left wrist, to include pain between her shoulder blades, the thoracic area and her left knee. The examiner noted that the veteran had limited extension of the neck, but that rotation, lateral bending and flexion were about normal, "done very deliberately and slowly." Shoulder motion was normal. Hand strength and small muscle tone were normal. The examiner found no evidence of hypothenar or thenar atrophy of either hand. The examiner summarized diagnostic testing showing increased arthritic changes in the cervical spine, dorsal scoliosis and "no obvious reason for her thoracic pain as far as the findings on the MRI report." The examiner suspected that the veteran had " a mild degree of radiculitis from surgery and possibly from her fall which flared it up." The examiner also wondered if the veteran had some trigger points seen with a myofascial or myositis type picture. The July 1995 report of spinal examination indicates diagnoses of post cervical fusion of C5 and C6 with degenerative, spinal stenosis of the cervical spine, scoliosis of D2 to D7, and evidence of inflammatory or post-traumatic findings at the mid-section. The examiner noted that the veteran had off-and-on symptoms of thoracic outlet syndrome. There was stated to be no real evidence of small muscle - 11 - atrophy. The examiner suspected anterior scalenus syndrome, occurring primarily when the veteran held her shoulders in one particular position. Nerve conduction testing completed in August 1995 was normal, without evidence of median or ulnar neuropathy, myotrophy or radiculopathy, or thoracic outlet syndrome. In an April 1996 decision, the Board rating in excess of 20 percent evaluation for the veteran's cervical spine disability. The present appeal stems from a subsequent rating decision of the RO denying the veteran an increased disability rating for her cervical spine and other disabilities. A psychiatry text excerpt includes note that "[m]any of the patients with chronic pain syndrome may be depressed, and the chronic pain may be an important symptom of their depression." Another psychiatry text includes note that "[a]mong [pain-related variables], longer duration of pain was associated with increased depression" and that [d]epression (DP) is a common comorbidity associated with chronic pain...." VA medical records dated in July and August 1996 reflect hospitalization of the veteran for a C6 to C7 diskectomy. In a letter dated in October 1996, M.T., Psy.D., reported that the veteran had been followed as an outpatient for four years, suffering from chronic pain and recurrent major depression. Dr. M.T. indicated that contributing to the veteran's depression was her struggle with chronic pain and stated that "[i]t is likely that there is an interaction between her emotional state and her physical condition with depression both resulting from the chronic pain as well as being an exacerbating factor of the pain. In a letter dated in October 1996, J.L., M.D., related treatment of the veteran for myofascial pain several times in the Boise VA pain clinic, treated with trigger point injections affording the veteran temporary relief. - 12 - Vet Center records reflect the veteran's complaints of cervical pain and a loss of tactile sense, with a history of major depression. The assessment in November 1996 by T.T., M.S.W., a Re- adjustment Counseling Therapist, was chronic pain from multiple injury to spine and major depression. The veteran was seen at a VA facility in November 1996. X-rays at that time indicate that the cervical spine was essentially the same as in September 1996, showing severe disc space narrowing at C5 to C6, C6 to C7, and mild to moderate narrowing at C4 to C5. Psychology records dated in October 1996 indicate that the veteran was "unable or unwilling to discuss the current cause of her distress..." In December 1996, she reported feeling useless since being unable to work. In a letter dated in November 1996, T.T., M.S.W., noted referral of the veteran in July 1996 for treatment of major depression, and that the veteran had multiple symptoms of major depression to include ongoing depressed mood, anhedonia, and reports of recurring thoughts of suicide. T.T. noted that the veteran "appears to relate her depressed mood to a number of associated issues, some ongoing, including: chronic pain, inability to work or to obtain a doctor's release to return to work, and her belief that she is "being jerked around. These complaints are related to her physical disability, which I believe is currently a service connected condition. Other issues are relatively recent, such as the death of a grand daughter. Still it appears that the primary source of the depression is rooted in [the veteran's] military service and medical discharge." A letter from K.B., M.D., dated in December 1996, indicates treatment of the veteran at the Boise VA mental health clinic for several years for chronic pain and depression and that the veteran's disability "remains intractable." A January 1997 letter from M.M., M.D., associated with VA, reports care of the veteran since July 1995 for severe degenerative joint disease, cervical and lumbar, and osteoporosis secondary to premature ovarian failure, due to which the veteran was "physically very restricted. She also suffers from depression, a lot of it probably related to her chronic pain due to the above condition." - 13 - VA records dated in April 1997 indicate that the veteran was doing better, that she would not pursue further surgery and that she had chronic pain syndrome. In June 1997 there were impressions of chronic pain and depression. A June 1997 emergency note includes a past medical history of chronic back pain, subsequent to surgeries in 1985 and 1996; scoliosis; osteoarthritis; osteoporosis; major depression; and a prior history of bleeding peptic ulcer -disease. At that time the veteran was treated for complaints of pain in her thoracic area; the impression was costochondritis versus chronic pain exacerbation versus cholecystitis. In July 1997, she received trigger point injections for her back pain. A June 1997 letter from the RO indicates that the veteran was denied vocational rehabilitation benefits as "it is not reasonably feasible for you to achieve a vocational goal, nor do we believe that you can benefit from a program of independent living service." A letter from K.L., M.D., dated in July 1997, notes that the veteran had marked fibrocystic changes in the left breast more than the right. A VA examination was conducted in August 1997. Severe progressive degenerative disc disease of the cervical, thoracic and lumbar spine was diagnosed Examination revealed that the veteran was "quite tender" over T2 to T4. Lumbar examination revealed good posture without seeming muscle spasm. There was minimal tenderness at L3. There was increased pain in the lumbar area with straight leg raising. There was slight anesthesia of the fourth and fifth toes on the let. Muscle strength seemed "alright." The veteran appeared without her crutch, having lost it. The examiner indicated that the veteran was totally disabled by the sum of her problems. The claims file contains a Social Security Administration (SSA) decision dated in July 1997, which indicates that the veteran was disabled based on depression and degenerative joint disease in the cervical and lumbar spine. The evaluation records note that the veteran had depressive syndrome, as characterized by a loss of interest; - 14 - appetite disturbance; sleep disturbance; decreased energy; and suicidal thoughts. The evaluation report indicates that such resulted in a marked restriction of activities of daily living, a moderate difficulty in maintaining social functioning, and continual episodes of deterioration or decompensation in work or work-like settings, causing the veteran to withdraw from that situation. In a statement dated in June 1998, Dr. J.L., of the VA Medical Center, reported having cared for the veteran for a year and stated that the veteran suffered from depression that was secondary to chronic pain. Dr. J.L. opined that such pain "is derived from [the veteran's] cervical spinal stenosis for which she has had surgeries in the past." An RO hearing was conducted in June 1998. The veteran complained of muscle spasm on a daily basis in different areas of her back. She reported a recent trip to the emergency room in June due to her lumbar problem. She stated that any type of activity would bring on spasm. She also reported daily pain on a scale of six-to- eight, out of ten. She testified that she was unable to do activities such as gardening or housecleaning and reported being able to walk only across the parking lot. She reportedly used a cane and crutches as her legs sometimes went out. The veteran stated that she was in receipt of SSA benefits for her back and indicated that a 20 percent evaluation for her lumbar spine would make her happy. She continued to express disappointment with her medical discharge from service, relating that she would get turned down for jobs and thus stopped applying. She testified that she was depressed due to her inability to continue and complete her 20 years of service, and also because of her pain. T.T., M.S.W., the veteran's therapist also testified, stating that the veteran was not malingering and that she suffered "significant depression related to pain ... also depression related to her discharge from the service." T.T., M.S.W., also opined the veteran's depression played a significant role in her inability to obtain or maintain employment. In a rating decision dated in July 1998 the RO assigned a 20 percent evaluation for degenerative joint disease and claimed arthritis of the lumbar spine; and a separate - 15 - 10 percent evaluation for degenerative joint disease of the thoracic spine, effective December 1, 1996. A VA examination of the veteran's spine was conducted in July 1998. The examiner reviewed the claims file and noted that since examination in August 1997 the veteran had had two episodes of "especially severe pain," one in December 1997 and one in June 1998. The examiner noted that the veteran had been taking pain medication since 1975 and that since 1991 she had been treated for depression. The report states that "[a] major element in the etiology of her depression has been considered to be her chronic pain." The examiner noted that the veteran was able to walk from her car to her house without her crutch, and part of the time around her house without a crutch. The veteran reported having people help her with activities such as doing her hair. The veteran complained of more significant pain in the thoracic than in the lumbar or cervical area, that cervical pain was accompanied by radiating pain into the ulnar aspect of her hands, and that she had minimal breast pain compared to her back problems. Examination in July 1998 revealed good posture with a normal lumbar curve. The veteran had flexion to 80 degrees, extension to zero degrees, lateral flexion to 30 degrees bilaterally, and rotation to 20 degrees bilaterally. Straight leg raising produced posterior thigh pain on the left at 40 degrees but no back pain. There was evidence of cervical tenderness. The veteran was tender to thoracic examination but not over the lumbar spine. The examiner summarized that there was continuing severe cervical disability of about the same degree as osteoporosis, with continuing severe disability of the thoracic and lumbar spine. There was no disability of the breasts. A Social and Industrial Survey was completed in August 1998. The report notes the veteran's background information and history, to include her military history and multiple medical problems. That report indicates that the veteran was on 100 percent SSA disability. The veteran reported that she was limited due her back pain and had extreme difficulty coping with lifestyle changes as a result. The interviewer noted that "[t]he veteran decompensated at this point in the interview, - 16 - stating that she is unable to talk further about her limitations as a result of her chronic pain and depression with the exception of stating that she can't make it through a day without lying down. In summary, the veteran's social and industrial functioning is severely limited related to her chronic pain and depression." In August 1998, a VA mental status examination was conducted. The veteran reported feelings of depression, subjectively stated to have begun during active duty and to have gotten worse with her medical problems. She reported poor sleep, a poor appetite, suicidal ideation, poor memory and trouble concentrating. The examiner commented that "on the surface the veteran does meet the criteria for major depressive disorder. The question has been raised as to the etiology of the depression. This examiner cannot render an opinion at this time as to cause ... It is this examiner's clinical hunch that the veteran may have a chronic personality disorder which predisposes her to depression and that her depression that is personality based may have been accentuated by her physical condition." After further review of the veteran's medical history and claims file, as well as additional testing by B.C., Ph.D., in September 1998, the examiner, in a September 1998 addendum, indicated that the veteran did not warrant an Axis I diagnosis of depression but rather an Axis 11 diagnosis of personality disorder not otherwise specified with borderline and schizotypal features. A report of Dr. B.C.'s testing is attached and concludes that the veteran had a mixed personality disorder characterized by features of borderline (poor affective control, exaggerated dependency needs, lack of interested in people, and a suggestion of use of splitting as a defense,) as well as schizoid or schizotypal features. The claims file contains VA outpatient records dated from July 1997 to October 1998. Those records reflect that the veteran was on hormone replacement therapy, subsequent to her hysterectomy. An undated problem list indicates that she has a pain medication contract and notes chronic pain from scoliosis. In December 1997 the veteran complained of mid-thoracic pain after lifting a heavy bag. In February 1998, the veteran reported sleep difficulties due to pain and indicated taking more Valium than recommended by her physician. A February 1998 note states "[s]till unclear as to cause of worsening pain." - 17 - March 1998 testing reports note that the veteran's report of sensation loss in her upper extremities was inconsistent with testing and function. An April 1998 report indicates that the veteran primarily complained of being unable to feel her hands. That report references an evaluation in March. The physician noted that there was "no evidence of emotional lability that was present previously." She was able to perform upper extremity ranges of motion, "[o]ccasional grimacing and volitional limitations with testing were noted though they were not a predominant part of the examination today." The impressions were significant deconditioning; chronic pain syndrome; subjective complaints of sensory and motor impairment, bilateral upper extremities; and prior significant thoracic pain not shown on examination that date. In June 1998, the veteran reported that her back "went out" that afternoon. She complained of chronic pain. Examination revealed her gait to be hesitant but normal. Outpatient notes dated in July and August 1998 show impressions of "chronic pain, depression." In September 1998, the veteran was seen at the pain clinic for repeat trigger point injections in her right parascapular region. That record indicates that despite the veteran's "multiple somatic complaints and heavy psychological over-lay, she does possess legitimate [left] hip pain..." In a letter dated in March 1999, T.T., M.S.W., summarized the veteran's history and evidence in the claims file, particularly the report of VA examination conducted in August 1998, with its September 1998 addendum. T.T. stated that when she spoke with the August/September 1998 VA examiner he did not recall having reviewed material that he had previously deemed necessary to clarify the "root of the depression," and that the September 1998 psychological evaluation conducted by Dr. B.C. did not include reference to a depression scale. T.T. expressed concern with the instructions provided to Dr. B.C. in connection with the requested psychological evaluation, and stated that if Dr. B.C. was asked to examine the veteran for a personality disorder and not depression it would make sense that he did not comment upon mood. T.T. related that the VA psychiatric examiner had verbally indicated that the veteran had a mixed personality disorder with depressed features. T.T. reported being unable to separate the veteran's chronic pain from her depressed mood. T.T. submitted records dated in November 1996 from the Vet Center reflecting the veteran's complaints of sleep disturbance, a poor appetite, - 18 - suicidal and homicidal thoughts and dissociative episodes. The Axis I diagnosis was major depression, with the precipitating Axis IV stressor noted as discharge from the Air Force resulting in a loss of status and a loss of sense of competence. Also submitted was the veteran's September 1996 account of a 1984 vacation and the interaction between her, her spouse and her children at that time. Also attached are progress notes dated from November 1996 to March 1999, which include note of the veteran's depression, anxiety and panic attacks. In a letter dated in April 1999, Dr. B.C. provided T.T., M. S.W.. with an explanation relevant to "the role of depression and physical disability in association with" the September 1998 VA examination of the veteran. Dr. B.C. indicated that he had been asked to clarify whether the veteran's personality disorder features contributed to her clinical presentation and he concluded in the affirmative. Dr. B.C. stated that his former conclusion implied that the veteran's capacity to cope with "the emotional distress (depression) that stems from her chronic physical disabilities is apt to be more complicated and problematic for her." Service Connection Pertinent Criteria In order to establish service connection for a claimed disability the facts must demonstrate that a disease or injury resulting in current disability was incurred in the active military service or, if pre-existing active service, was aggravated therein. 38 U.S.C.A. 1110, 1131 (West 1991); 38 C.F.R. 3.303 (1999). Personality disorders and mental deficiency as such are not diseases or injuries within the meaning of applicable legislation. 38 C.F.R. 3.303(c); 4.9 (1999). Where a veteran served for at least 90 days during a period of war or after December 31, 1946, and certain chronic diseases, such as psychoses, become manifest to a degree of 10 percent within one year from the date of termination of such service, such diseases shall be presumed to have been incurred in service, even - 19 - though there is no evidence of such diseases during the period of service. 38 U.S.C.A. 1101, 1112, 1113 (West 1991); 38 C.F.R. 3.307, 3.309 (1999). Where there is a chronic disease shown as such in service or within the presumptive period under 38 C.F.R. 3.307 so as to permit a finding of service connection, subsequent manifestations of the same chronic disease at any later date, however remote, are service connected, unless clearly attributable to intercurrent causes. 38 C.F.R. 3.303(b). This rule does not mean that any manifestation in service will permit service connection. To show chronic disease in service there is required a combination of manifestations sufficient to identify the disease entity, and sufficient observation to establish chronicity at the time, as distinguished from merely isolated findings or a diagnosis including the word "chronic." When the disease identity is established, there is no requirement of evidentiary showing of continuity. When the fact of chronicity in service is not adequately supported, then a showing of continuity after discharge is required to support the claim. 38 C.F.R. 3.303(b). The chronicity provision of 38 C.F.R. 3.303(b) is applicable where evidence, regardless of its date, shows that a veteran had a chronic condition in service and still has such condition. Such evidence must be medical unless it relates to a condition as to which, under the Court's case law, lay observation is competent. If the chronicity provision is not applicable, a claim may still be well grounded if (1) the condition is observed during service, (2) continuity of symptomatology is demonstrated thereafter and (3) competent evidence relates the present condition to that symptomatology. Savage v. Gober, 10 Vet. App. 489 (1997); see also Grottveit v. Brown, 5 Vet. App. 91, 93 (1993) (where the issue involves questions of medical diagnosis or an opinion as to medical causation, competent medical evidence is required). Service connection is also warranted for disability proximately due to or the result of a service-connected disorder and where aggravation of a nonservice-connected disorder is proximately due to or the result of a service-connected disability. In the case of aggravation, such secondary disorder is compensable only to the degree of disability over and above the degree of disability which would exist without such - 20 - aggravation. 38 C.F.R. 3.310(a); Allen v. Brown, 7 Vet. App. 439, 448, 449 (1995). Service connection may also be granted for a disease diagnosed after discharge, when all the evidence, including that pertinent to service, establishes that the disease was incurred in service. 38 C.F.R. 3.303(d). "[A] person who submits a claim for benefits under a law administered by the Secretary shall have the burden of submitting evidence sufficient to justify a belief by a fair and impartial individual that the claim is well grounded." 38 U.S.C.A. 5107(a); Carbino v. Gober, 10 Vet. App. 507 (1997); Anderson v. Brown, 9 Vet. App. 542, 545 (1996). A well-grounded claim is "a plausible claim, one which is meritorious on its own or capable of substantiation. Such a claim need not be conclusive but only possible to satisfy the initial burden of [section 5107(a)]." Murphy v. Derwinski, 1 Vet. App. 79, 81 (1990). In Tirpak v. Derwinski, 2 Vet. App. 609, 611 (1992), the Court held that a claim must be accompanied by supportive evidence and that such evidence "must 'Justify a belief by a fair and impartial individual' that the claim is plausible." Generally, for a claim to be well grounded, there generally must be (1) a medical diagnosis of a current disability; (2) medical or, in certain circumstances, lay evidence of in-service occurrence or aggravation of a disease or injury; and (3) medical evidence of a nexus between an in-service injury or disease and the current disability. See Anderson, supra,- Caluza v. Brown, 7 Vet. App. 498, 506 (1995), aff'd, 78 F.3d 604 (Fed. Cir. 1996) (table). In any case, a claim for service- connection for a disability must be accompanied by evidence which establishes that the claimant currently has the claimed disability. Absent proof of a present disability there can be no valid claim. See, e.g., Gilpin v. West, 155 F.3d 1353 (Fed. Cir. 1998); Degmetich v. Brown, 104 F.3d 1328 (Fed. Cir. 1997); Brammer v. Derwinski, 3 Vet. App. 223, 225 (1992); Rabideau v. Derwinski, 2 Vet. App. 141, 144 (1992). - 21 - Medical evidence is required to prove the existence of a current disability and to fulfill the nexus requirement. Lay or medical evidence, as appropriate, may be used to substantiate service incurrence. See Layno v. Brown, 6 Vet. App. 465, 469 (1994); Grottveit v. Brown, 5 Vet. App. 91, 93 (1993). In a claim of secondary service connection, the question of the relationship of one condition to another is not susceptible to informed lay observation and thus, for there to be credible evidence of such a relationship, medical evidence is required. Reiber v. Brown, 7 Vet. App. 513, 516 (1995) (requiring medical evidence showing a relationship between a fall due to a service- connected left ankle disability and claimed secondary service connection for a back condition). For the purposes of determining whether this claim is well grounded, the Board must presume the truthfulness of the evidence, "except when the evidentiary assertion is inherently incredible or when the fact asserted is beyond the competence of the person making the assertion." King v. Brown, 5 Vet. App. 19, 21 (1993). If a claim is not well grounded, the application for service connection must fail, and there is no further duty to assist the veteran in the development of his claim. 38 U.S.C.A. 5107, Murphy v. Derwinski, 1 Vet. App. 78 (1990). Analysis In this case, the veteran's claim of entitlement to service connection for depression is well grounded in that there is competent opinion from medical professionals to the effect that the veteran has depression related pain resulting from her service- connected spinal disabilities. See 38 C.F.R. 3.310 and Reiber, supra. The Board is also satisfied that all relevant and available facts have been properly developed. The veteran has been examined by the VA in connection with her claim and has not identified any additional, relevant evidence that has not been requested or obtained. The Board finds all relevant evidence necessary for an equitable disposition of the - 22 - appeal has been obtained, and no further assistance is required to comply with the duty to assist mandated by 38 U.S.C.A. 5107. The evidence in this case does not show that the veteran was diagnosed with a depressive disorder during her period of service. In fact, psychological evaluation in service showed only impressions of situational reaction and suggested "hypochondriacal adjustment patterns" and "characterological elements." Evaluation reports, to include the report of the PEB, do not reflect a diagnosed depressive disorder. Nor did the veteran claim such at the time of her initial claim for VA compensation benefits. Rather, her claim for depression came later, at which time she argued that it had developed as a result of her medical discharge and/or secondary to the chronic pain she experienced as a result of her service- connected disabilities, mainly her spinal disorders. The Board notes that the claims file contains extensive treatment records that mention the veteran's depressed mood and depression symptoms and chronic pain. Some progress and treatment notes contain the word "depression" as among the veteran's noted problems. Also, the Board recognizes the submitted medical texts pertinent to the rise of depression coincident with chronic pain. Finally, a number of healthcare professionals, to include M.D.'s, Ph.D.'s, and M.S.W.'s, have provided opinions that the veteran has depression secondary to chronic pain resulting from her spinal disabilities. There is no question that the veteran suffers from depression. The question raised by the record is whether such depression is a symptom and a factor of the veteran's identified personality disorder, for which service connection is not in order, see 38 C.F.R. 3.303, 4.9; or, whether she meets the diagnostic criteria for an acquired depressive disorder, which is service-connectable if shown to have been incurred as a result of service or service- connected disability. See 38 C.F.R. 3.303, 3.310. The evidence referenced in the above paragraph supports the veteran's contention that she has depression due to her pain, but leaves unclear the question of whether depression as discussed in the varying records is a symptom or diagnostic entity. 23 - In the veteran's favor is the SSA decision awarding benefits based on depression and spinal problems. That decision is based, in part, on a report of psychiatric evaluation finding that the veteran exhibited at least four of the symptoms requisite for a diagnosis of an affective disorder. Also in the veteran's favor is the opinion of T.T., M.S.W., who provided an Axis I diagnosis of major depression after ongoing treatment and evaluation of the veteran. Against the veteran's claim is the report of August 1998 VA examination, showing that the VA examiner initially opined that the veteran did meet the diagnostic criteria for a depressive disorder on the surface, but revised that opinion and concluded that based on a review of psychological testing the veteran had a personality disorder and did not warrant an Axis I diagnosis of depression. The Board notes the dialogue between T.T., M.S.W., and Dr. B.C., the psychologist who conducted the September 1998 testing. Their correspondence reflects a continued lack of clarity as to whether the veteran's depression is considered adequate by medical professionals to constitute an acquired psychiatric disorder as opposed to a trait of a personality disorder or a symptom, not attributable to any diagnosed psychiatric disorder. Such lack of clarity is further complicated by evidence suggesting that the veteran's personality disorder has predisposed her to depression. Also significant in this discussion are the aforementioned opinions by varying health care professionals stating that the veteran has depression related to the pain caused by her service-connected disabilities. Those individuals did not specify whether the veteran met the diagnostic criteria for any depressive disorder, just concluding that she has "depression." Upon reviewing the evidentiary record, the Board finds that there is an approximate balance of positive and negative evidence regarding the merits of the issue. See Gilbert v. Derwinski, 1 Vet. App. 49, 53 (1990. Thus, the Board will resolve any doubt in the veteran's favor and conclude that service connection for depression is - 24 - warranted as a disability causally related to her service-connected spinal disorders. See 38 C.F.R. 3.310(a). Increased Ratings Pertinent Criteria Disability evaluations are determined by the application of VA's Schedule for Rating Disabilities (Schedule), 38 C.F.R. Part 4 (1999). The percentage ratings contained in the Schedule represent, as far as can be practicably determined, the average impairment in earning capacity resulting from diseases and injuries incurred or aggravated during military service and the residual conditions in civil occupations. 38 U.S.C.A. 1155; 38 C.F.R. 4.1 (1999). In determining the disability evaluation. the VA has a duty to acknowledge and consider all regulations which are potentially applicable based upon the assertions and issues raised in the record and to explain the reasons and bases for its conclusion. Schafrath v. Derwinski, 1 Vet. App. 589 (1991). Governing regulations include 38 C.F.R. 4.1, 4.2 (1999), which require the evaluation of the complete medical history of the veteran's condition. Where entitlement to compensation has already been established and an increase in the disability rating is at issue, the present level of disability is of primary concern. Francisco v. Brown, 7 Vet. App. 55, 58 (1994). Where there is a question as to which of two evaluations shall be applied, the higher evaluation will be assigned if the disability picture more nearly approximates the criteria for that rating. Otherwise the lower rating will be assigned. 38 C.F.R. 4.7 (1999). All benefit of the doubt will be resolved in the veteran's favor. 38 C.F.R. 4.3 (1999). Disability of the musculoskeletal system is the inability to perform normal working movement with normal excursion, strength, speed, coordination, and endurance, and that weakness is as important as limitation of motion, and that a part which becomes disabled on use must be regarded as seriously disabled. However, a little-used part of the musculoskeletal system may be expected to show evidence of disuse, through - 25 - atrophy, for example. 38 C.F.R. 4.40. The provisions of 38 C.F.R. 4.45 and 4.59 contemplate inquiry into whether there is crepitation, limitation of motion, weakness, excess fatigability, incoordination, and impaired ability to execute skilled movements smoothly, and pain on movement, swelling, deformity, or atrophy of disuse. Instability of station, disturbance of locomotion, and interference with sitting, standing, and weight-bearing are also related considerations. It is the intention of the rating schedule to recognize actually painful, unstable, or mal-aligned joints, due to healed injury, as at least minimally compensable. 38 C.F.R. 4.71a, Diagnostic Code 5285 (1999) contemplates disability arising from residuals of vertebral fracture. Under this code, with cord involvement, bedridden or requiring long leg braces, a 100 percent disability rating is assigned. Without cord involvement; abnormal mobility requiring neck brace (jury mast), a 60 percent disability rating is assigned. In other cases, rating is in accordance with definite limited motion or muscle spasm, adding 10 percent for demonstrable deformity of the vertebral body. Limitation of motion of the dorsal spine warrants a maximum 10 percent evaluation where such limitation is moderate or severe under 38 C.F.R. 4.71a, Diagnostic Code 5291 (1999). Slight limitation of the lumbar spine is evaluated as 10 percent disabling; moderate limitation is evaluated as 20 percent disabling and severe limitation is evaluated as 40 percent disabling. 38 C.F.R. 4.71a, Diagnostic Code 5292 (1999). 38 C.F.R. 4.71a, Diagnostic Code 5293 pertains to intervertebral disc syndrome. Under that code, a zero percent evaluation is applied to a post-operative, cured condition. A 10 percent evaluation requires mild symptoms. A 20 percent evaluation is for moderate symptoms and recurring attacks. A 40 percent evaluation is applied for severe symptoms characterized by recurring attacks with intermittent relief. A 60 evaluation is the maximum evaluation for this diagnostic code, requiring evidence of a pronounced condition, with persistent symptoms compatible with sciatic neuropathy with characteristic pain and demonstrable muscle spasm, absent ankle jerk, or other neurological findings appropriate to the site of the diseased disc, with little intermittent relief. Lumbosacral strain is evaluated under 38 C.F.R. 4.71a, Diagnostic Code 5295 (1999). With muscle spasm on extreme forward bending, loss of lateral spine motion, unilateral, in a standing position, a 20 percent evaluation is warranted. Where symptoms are severe with listing of the whole spine to the opposite side; positive Goldthwaite's sign, marked limitation of forward bending in a standing position, a loss of lateral motion with osteo-arthritic changes, or narrowing or irregularity of joint space, or some of the above with abnormal mobility on forced motion, a maximum 40 percent evaluation is warranted. 38 C.F.R. 4.71a, Diagnostic Code 5010 (1999) applies to traumatic arthritis and provides that such is evaluated based on limitation of motion of the affected part, like degenerative arthritis. See 38 C.F.R. 4.71a, Diagnostic Code 5003 (1999). Where the limitation of motion of the specific joint or joints involved is noncompensable, under the applicable diagnostic codes, a rating of 10 percent is warranted where arthritis is shown by x-ray and where limitation of motion is objectively confirmed by evidence of swelling, muscle spasm, or painful motion. The Court, in DeLuca v. Brown, 8 Vet. App. 202 (1995), held that where evaluation is based on limitation of motion, the question of whether pain and functional loss are additionally disabling must be considered. See 38 C.F.R. 4.40, 4.45, 4.59. Consideration of functional loss due to pain is not required when the current rating is the maximum disability rating available for limitation of motion. Johnston v. Brown, 10 Vet. App. 80, 85 (1997). The VA Office of the General Counsel has issued a precedent opinion that appears to mandate such consideration even where the veteran is in receipt of the maximum percentage under the diagnostic codes pertaining to limitation of motion. See VAOPGCPREC 36-97 (December 12, 1997). Pyramiding, that is the evaluation of the same disability, or the same manifestation of a disability, under different diagnostic codes, is to be avoided when rating a - 27 - veteran's service-connected disabilities. 38 C.F.R. 4.14 (1999). It is possible for a veteran to have separate and distinct manifestations from the same injury which would permit rating under several diagnostic codes. The critical element in permitting the assignment of several ratings under various diagnostic codes is that none of the symptomatology for any one of the conditions is duplicative or overlapping with the symptomatology of the other condition. See Esteban v. Brown, 6 Vet. App. 259, 261-62 (1994). Initial Matters In general, allegations of increased disability are sufficient to establish well- grounded claims seeking increased ratings. Proscelle v. Derwinski, 2 Vet. App. 629 (1992). In the instant case, there is no indication that there are additional records that have not been obtained and which would be pertinent to the lumbar and thoracic claims. The claims file contains records of VA and private treatment and evaluation, as well as multiple reports of VA examination of the veteran's spine. She has not identified further relevant evidence that has not been requested or obtained. Thus, no further development is required in order to comply with VA's duty to assist mandated by 38 U.S.C.A. 5107(a). Also, pertinent to each area of the spine discussed below, the Board notes that the words "slight," "moderate" and "severe" as used in the various diagnostic codes are not defined in the Schedule. Rather than applying a mechanical formula, the Board must evaluate all of the evidence to the end that its decisions are "equitable and just." 38 C.F.R. 4.6 (1999). It should also be noted that use of terminology such as "mild," etc. by VA examiners and others, although an element of evidence to be considered by the Board, is not dispositive of an issue. Rather, all evidence must be evaluated in arriving at a decision regarding an increased rating. 38 C.F.R. 4.2, 4.6 (1999). - 28 - Analysis Thoracic Spine The veteran is currently assigned a 10 percent evaluation for her thoracic spine disability. That 10 percent evaluation is the maximum available for the thoracic spine under 38 C.F.R. 4.71a, Diagnostic Code 5291 pertaining to limitation of motion, or under 38 C.F.R. 4.71a, Diagnostic Codes 5003, 5010, pertaining to arthritis. The RO has evaluated the veteran as 10 percent disabled by virtue of her thoracic symptomatology using 38 C.F.R. 4.71a, Diagnostic Code 5293. The Board recognizes that diagnostic test reports show impressions of degenerative disc disease at multiple levels of the spine, including the thoracic spine. In that regard, the Board notes that service records are consistent in noting no evidence of radiculopathy or other neurologic impairment resulting from thoracic spine disease. Rather, such records show subjective complaints of pain with retention of a full range of back motion as of September 1990, and, in connection. with the PEB, service personnel noted that objective work-ups had not revealed a specific etiology for the degree of pain expressed by the veteran. Service records instead note a somataform pain disorder. Post-service records continue to suggest functional overlay in the degree of pain expressed by the veteran relevant to her thoracic spine. In April 1992 the examiner noted such and referenced testing negative for radiculopathy. October 1993 notes indicate that the veteran's symptoms might be "positional," with testing showing only mild degenerative changes stated to be consistent with the veteran's age. A CT in September 1994 did reveal what appeared to be a lesion in the thoracic spine causing cord distortion; however, testing in June 1995 was again stated to show "no obvious reason" for thoracic spine pain. The grant of SSA benefits is based on disability of the cervical and lumbar spine, not the thoracic spine. An April 1998 treatment record notes that significant thoracic pain was not shown on examination, and examination in July 1998 showed only subjective thoracic - 29 - tenderness. In short, the competent evidence of record does not show spasm, neurologic impairment, or other symptomatology beyond complaints of pain that has been attributed to the thoracic disability. Thus, despite several notations in medical reports that the veteran suffered from "severe" disability of each area of her spine, there is no competent evidence of objective pathology beyond pain resulting from degeneration. In particular, there is no evidence of neurologic impairment of the thoracic spine. As such, no more than a 10 percent evaluation for mild disc syndrome manifested by pain is warranted. See 38 C.F.R. 4.71a, Diagnostic Code 5293. Consideration has also been given to the potential application of the various provisions of 38 C.F.R. Parts 3 and 4 (1998), whether or not they were raised by the veteran, as required by Schafrath v. Derwinski, 1 Vet. App. 589 (1991). However, the Board finds no basis upon which to assign a higher disability evaluation. Specifically, the competent evidence does not show that the veteran's thoracic spine is ankylosed; that she suffered any fracture of the thoracic spine with or without spinal cord involvement; or that she has symptomatic thoracic spine scarring to warrant consideration under 38 C.F.R. 4.71a, 4.118, Diagnostic Codes 5285, 5288, 7803, 7804, 7805 (1999). See 38 C.F.R. 4.14. Furthermore, as the veteran's thoracic spine is evaluated at the maximum for limitation of motion, consideration of additional functional loss is not warranted. Johnston v. Brown, 10 Vet. App. 80, 85 (1997). Lumbar Spine A 20 percent evaluation is currently assigned for the veteran's lumbar spine disability, under 38 C.F.R. 4.71a, Diagnostic Code 5293. To warrant assignment of a 40 percent evaluation under that code, there would have to be competent and probative evidence of severe, recurring attacks of lumbar disc disease symptoms such as sciatic neuropathy, absent ankle jerk or other neurologic findings, with only intermittent relief. An MRI of the lumbar spine in October 1992 was normal. August 1993 records suggest mechanical low back pain and not sciatic involvement. More recent examination reports or treatment records do not document sciatic - 30 - neuropathy or severe lumbar symptomatology. In fact, there is no objective pathologic or diagnostic evidence of sciatica or neurologic symptoms attributable to disc disease of the lumbar spine to warrant an increased evaluation under Diagnostic Code 5293. Moreover, the competent evidence of record shows no severe limitation of lumbar motion or other symptomatology resulting in more than moderate lumbar disability. A review of the evidentiary record shows that the veteran's complaints in connection with treatment and/or examination focus mainly on the thoracic and cervical portions of her spine. In June 1991 she was able to touch her toes without difficulty. Her gait, coordination and balance were normal in May 1995, without evidence of weakness, muscle wasting or radiating symptomatology in the lower extremities. VA examination in August 1997 showed good lumbar posture, without evidence of muscle spasm. The examiner characterized any tenderness as "minimal" and stated that muscle strength seemed all right. And, at the time of most recent examination of the lumbar spine, in July 1998, there was no evidence of lumbar spine tenderness. The examiner's characterization of the lumbar spine disability as severe at the time of that examination, and other notations of "severe" lumbar problems appears to be based on diagnostic evidence and/or a history of severe spine problems. Moreover, the veteran has stated that she would be satisfied with a 20 percent evaluation, the evaluation currently assigned to her disability. The medical findings in this case do not support assignment of more than a 20 percent evaluation as there is no competent evidence of a severe loss of lumbar spine motion, a loss of unilateral spine motion, listing, lumbar spasm or sciatic neuropathy. See Diagnostic Codes 5292, 5293, 5295. The Board also notes that the veteran's currently assigned 20 percent evaluation is based on consideration of limitation of lumbar motion with pain, and diagnostic evidence of degenerative changes. As such, no separate evaluation is warranted for arthritis, or based on consideration of 38 C.F.R. 4.40, 4.45, 4.59. See 38 C.F.R. 4.14. With respect to the latter, the Board also points to ample evidence of functional overlay and claimed symptomatology not consistent with and/or supported by objective medical evidence. As such, no higher evaluation for lumbar disability is warranted based on the evidence of record. - 31 - Consideration has also been given to the potential application of the various provisions of 38 C.F.R. Parts 3 and 4 (1998), whether or not they were raised by the veteran, as required by Schafrath v. Derwinski, 1 Vet. App. 589 (1991). However, the Board finds no basis upon which to assign a higher disability evaluation. ORDER Service connection for depression is granted. An evaluation in excess of 20 percent for service-connected degenerative disc disease of the lumbar spine is denied. An evaluation in excess of 10 percent for service-connected degenerative disc disease of the thoracic spine is denied. REMAND The veteran's service connected disabilities are degenerative disc disease of the cervical spine, evaluated as 40 percent disabling; degenerative disc disease of the lumbar spine, evaluated as 20 percent disabling; degenerative disc disease of the thoracic spine, evaluated as 10 percent disabling; a gastric ulcer with dyspepsia, evaluated as 10 percent disabling; fibrocystic breast disease, evaluated as 10 percent disabling; bronchitis, evaluated as 10 percent disabling; and left hip abductor muscle strain; scars on the left wrist from excision of a ganglion cyst; residuals of fracture to the third and fourth metatarsals of the right foot; residuals of injury to the left foot; left kidney nephrolithiasis; a euthyroid nodular goiter; and sinusitis, each evaluated as zero percent disabling. Her combined rating is 70 percent. In addition, the Board has granted service connection for depression, which will have to be rated initially by the RO. In view of the percentage ratings already in effect, the schedular criteria for TDIU have been met. 38 C.F.R. 4.16(a). However, the - 32 - veteran's claim of entitlement to TDIU is inextricably intertwined with her appeal for an increased evaluation for the cervical spine disability. Prior to adjudication of the increased rating issue, further development is necessary. In that regard the Board notes that the veteran has recently submitted records reflecting cervical spine surgery in December 1999. Although she has waived her right to initial RO consideration of such evidence, see 38 C.F.R. 20.1304(c) (1999), the post- operative status of her cervical spine must be assessed. Thus, additional examination is warranted to ensure proper adjudication of her claim. Hyder v. Derwinski, 1 Vet. App. 221 (1991); Littke v. Derwinski, 1 Vet. App. 90 (1990). Moreover, additional development is necessary for the RO to rate the now service- connected depression and to consider the industrial impairment resulting from depression and its role in the veteran's ability to maintain gainful employment is warranted. The medical records on file reflect, in part, that when the veteran was seen for a neurologic consultation in October 1991 she was noted to be "very emotionally unstable." Although she reported an inability to use her left upper extremity and thus to find work and that she would tell prospective employers that she was medically discharged from service due to "inability to lift any objects of any weight whatsoever because her arm will give way," the examiner found good strength in the upper extremity and identified no atrophy or fasciculations, and no loss of sensory modalities. Thus the examiner indicated that there was a considerable amount of functional overlay. The record further reflects that in March 28, 1996, it was noted that frequent movement of heavy equipment at work had aggravated the veteran's spinal condition, and that surgery on her cervical disc would allow her to be employed without significant limitations. VA medical records show that in mid- 1996 she underwent a C6 to C7 diskectomy. In December 1999 the veteran underwent additional cervical spine surgery, as reflected in the most recent medical evidence. - 33 - That evidence also notes that the veteran "has a long-standing history of narcotic dependence. She was notably on approximately 100 mg of morphine sulfate a day." The veteran's narcotic dependence was noted to make post-operative pain control "a major issue." In view of the veteran's recent surgery and the Board's grant of service connection for a psychiatric disorder, this case is remanded to the RO for the following: 1. The RO should ensure that all records of VA treatment and evaluation of the veteran's depression and cervical spine disability to date are associated with the claims file. The RO should also provide the veteran opportunity to identify private medical evidence pertinent to those disabilities and/or her ability to maintain gainful employment. With her consent, the RO should obtain any identified records. 2. The RO should arrange for examination of the veteran by a panel to include a psychiatrist, a neurologist and an orthopedist. If possible each should be board-certified and not a current or former treating physician of the veteran. The claims folder and a separate copy of this remand should be made available to each of the examiners and reviewed by each. The psychiatrist is requested to comment on the nature and severity of symptoms attributable to depression and to provide an opinion as to the limitations and level of functional impairment resulting from such depression. Any impairment that results from the noted narcotic dependence or from any personality disorder if found must not be considered. - 34 - The orthopedic and neurologic examiners are requested to identify the nature, frequency, duration and severity of all manifested orthopedic and neurologic symptoms attributable to the veteran's cervical spine disability, to include comment as to any resulting functional loss. In view of evidence in the file suggesting that there may be a non-organic component to the veteran's cervical spine complaints, the panel is specifically requested to assess any somatic dysfunction/functional overlay/exaggeration or the like, along with the effect of the veteran's noted narcotics dependence, and provide an opinion as to whether the physical limitations claimed by the veteran are consistent and proportionate to the pathology shown on examination and in the evidence of record. It is essential that the medical board identify findings that do or do not support the veteran's complaints and reported limitations, in view of, for example, her admission that she informs potential employers that she is incapable of lifting any weight above her head. The three examiners are additionally requested to comment jointly, if feasible, on the impact of the veteran's service-connected physical and psychiatric disabilities, in combination, on her ability to maintain gainful employment, specifically setting out the occupational limitations resulting from her disabilities. Again, any work impairment resulting directly or otherwise from her narcotic dependence should not be considered. The veteran's credibility and that of the evidence should be considered in reaching a conclusion. - 35 - 3. After the development requested above has been completed to the extent possible, the RO should review the record to ensure that such is adequate for appellate review. The RO is advised that where the remand orders of the Board or the Court are not complied with, the Board errs as a matter of law when it fails to ensure compliance, and further remand will be mandated. Stegall v. West, 11 Vet. App. 268 (1998). After any indicated corrective action has been completed, the RO should assign a disability rating to the veteran's now service-connected depression. The RO should thereafter re-adjudicate the veteran's claims of entitlement to an increased rating for cervical spine disability and entitlement to TDIU benefits. If any benefit sought on appeal remains denied the veteran and her representative should be furnished a supplemental statement of the case and given the opportunity to respond thereto. Thereafter, the case should be returned to the Board, if in order. The Board intimates no opinion as to the ultimate outcome of this case. The veteran need take no action unless otherwise notified. The veteran has the right to submit additional evidence and argument on the matters the Board has remanded to the RO. Kutscherousky v. West, 12 Vet. App. 369 (1999). This claim must be afforded expeditious treatment by the RO. The law requires that all claims that are remanded by the Board or by the Court for additional development or other appropriate action must be handled in an expeditious manner. See The Veterans' Benefits Improvements Act of 1994, Pub. L. No. 103-446, 302, 108 Stat. 4645, 4658 (1994), 38 U.S.C.A. 5101 (West Supp. 1996) (Historical and Statutory Notes). In addition, VBA's ADJUDICATION PROCEDURE MANUAL, M21-1, Part IV, directs the ROs to provide expeditious handling of all cases that - 36 - have been remanded by the Board and the Court. See M21-1, Part IV, paras. 8.44-8.45 and 38.02-38.03. JANE E. SHARP Member, Board of Veterans' Appeals
