Entitlement to an increased rating for dysthymic disorder, currently rated 50 percent disabling. 2. Entitlement to an increased rating for spina bifida occulta with discogenic low back pain and lumbosacral strain, currently rated 20 percent disabling. 3.

Entitlement to a total disability rating based on individual unemployability due to service-connected disability (TDIU). REPRESENTATION Appellant represented by: Allan T. Fenley, Attorney at law ATTORNEY FOR THE BOARD W. Harryman, Counsel INTRODUCTION The Veteran had active duty from March 1990 to January 1996. This matter comes before the Board of Veterans' Appeals (Board) on appeal from an August 2007 decision of the Department of Veterans Affairs (VA) Regional Office (RO) in Ft. Harrison, Montana. The case was later transferred to the RO in Fargo, North Dakota. The issues concerning an increased rating for dysthymic disorder and a TDIU being remanded are addressed in the REMAND portion of the decision below and are REMANDED to the Department of Veterans Affairs Regional Office. FINDINGS OF FACT 1. The Veteran's service-connected spina bifida occulta with discogenic low back pain and lumbosacral strain has been manifest throughout the appeal period by limitation of forward flexion of the thoracolumbar spine to no less than 60 degrees; ankylosis of the entire thoracolumbar spine has not been shown. 2. Irritable bowel syndrome has been manifest throughout the appeal period by not more than mild disturbances of bowel function with occasional episodes of abdominal distress. CONCLUSIONS OF LAW 1. The criteria are not met for a rating greater than 20 percent for spina bifida occulta with discogenic low back pain and lumbosacral strain. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 4.1, 4.2, 4.7, 4.10, 4.40, 4.45, 4.59, and 4.71a, Code 5242 (2009). 2. The criteria are not met for a compensable rating for irritable bowel syndrome. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 4.1, 4.2, 4.7, 4.10, 4.114, Code 7319 (2009). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS I. Duties to notify and to assist Under the Veterans Claims Assistance Act (VCAA), when VA receives a complete or substantially complete application for benefits, it must notify the claimant of the information and evidence not of record that is necessary to substantiate a claim, which information and evidence VA will obtain, and which information and evidence the claimant is expected to provide. 38 U.S.C.A. § 5103(a) (West 2002). 38 C.F.R. § 3.159 (2009). See also Pelegrini v. Principi, 18 Vet. App. 112, 120-21 (2004) (Pelegrini II). In the instant case, the Veteran received proper notification prior to the initial unfavorable decision in August 2007. The RO's January 2007 notice letter advised the Veteran what information and evidence was needed to substantiate the claims decided herein and what information and evidence must be submitted by him, namely, any additional evidence and argument concerning the claimed conditions and enough information for the RO to request records from the sources identified by the Veteran. He was specifically told that it was his responsibility to support the claims with appropriate evidence. Finally the letter advised him what information and evidence would be obtained by VA, namely, records like medical records, employment records, and records from other Federal agencies. The duty to notify the Veteran was satisfied under the circumstances of this case. 38 U.S.C.A. § 5103. VA must also make reasonable efforts to assist the appellant in obtaining evidence necessary to substantiate the claim for the benefit sought, unless no reasonable possibility exists that such assistance would aid in substantiating the claims. 38 U.S.C.A. § 5103A; 38 C.F.R. § 3.159 (2009). Service treatment records are associated with claims file. Post-service treatment records and reports from various VA Medical Centers have also been obtained. A decision from the Social Security Administration and the records it considered in support of its decision are on file. The Veteran has not identified any additional records that should be obtained prior to a Board decision. Therefore, VA's duty to further assist the Veteran in locating additional records has been satisfied. The Veteran was afforded a VA examination for his gastrointestinal and low back spine disabilities February 2007. There is no objective evidence indicating that there has been a material change in the severity of the Veteran's spina bifida occulta or irritable bowel syndrome since he was last examined. See 38 C.F.R. § 3.327(a) (2009). The duty to assist does not require that a claim be remanded solely because of the passage of time since an otherwise adequate examination was conducted. VAOPGCPREC 11-95. The Veteran's attorney contended generally in the September 2007 notice of disagreement that VA failed to provide adequate medical examinations to assess his disabilities. The attorney did not provide any rationale to support that argument, however. The Veteran was also afforded a VA compensation examination in February 2007 and a VA Gulf War examination in August 2007. The Board finds both examination reports to be thorough, complete, and adequate upon which to base a decision with regard to this claim. The VA examiners reported the Veteran's symptoms and current clinical findings in detail. They had an opportunity to personally interview and examine the Veteran, and their reports provide the information necessary to evaluate the Veteran's disabilities under the applicable rating criteria. The February 2007 and August 2007 examination reports are deemed adequate for rating purposes. Barr v. Nicholson, 21 Vet. App. 303, 312 (2007). In light of the foregoing, the Board is satisfied that all relevant facts have been adequately developed to the extent possible; no further assistance to the Veteran in developing the facts pertinent to the issues on appeal is required to comply with the duty to assist. 38 U.S.C.A. §§ 5103 and 5103A; 38 C.F.R. § 3.159. II. Law and regulations Disability ratings are determined by applying the criteria set forth in the VA Schedule for Rating Disabilities, found in 38 C.F.R., Part 4. The rating schedule is primarily a guide in the evaluation of disability resulting from all types of diseases and injuries encountered as a result of or incident to military service. The ratings are intended to compensate, as far as can practicably be determined, the average impairment of earning capacity resulting from such diseases and injuries and their residual conditions in civilian occupations. 38 U.S.C.A. § 1155; 38 C.F.R. § 4.1. 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. 38 C.F.R. § 4.7. In considering the severity of a disability, it is essential to trace the medical history of the Veteran. 38 C.F.R. §§ 4.1, 4.2, 4.41. Consideration of the whole-recorded history is necessary so that a rating may accurately reflect the elements of disability present. 38 C.F.R. § 4.2; Peyton v. Derwinski, 1 Vet. App. 282 (1991). Where a veteran appeals the denial of a claim for an increased disability rating for a disability for which service connection was in effect before he filed the claim for increase, the present level of the veteran's disability is the primary concern, and past medical reports should not be given precedence over current medical findings. Francisco v. Brown, 7 Vet. App. 55, 57-58 (1994). However, where VA's adjudication of the claim for increase is lengthy and factual findings show distinct time periods where the service-connected disability exhibits symptoms which would warrant different ratings, different or "staged" ratings may be assigned for such different periods of time. Hart v. Mansfield, 21 Vet. App. 505, 509-510 (2007). The assignment of a particular diagnostic code is "completely dependent on the facts of a particular case." Butts v. Brown, 5 Vet. App. 532, 538 (1993). One diagnostic code may be more appropriate than another based on such factors as an individual's relevant medical history, the diagnosis and demonstrated symptomatology. Any change in a diagnostic code by a VA adjudicator must be specifically explained. Pernorio v. Derwinski, 2 Vet. App. 625, 629 (1992). Spina bifida, discogenic low back pain, and lumbosacral strain Disability of the musculoskeletal system is primarily the inability, due to damage or infection in the parts of the system, to perform the normal working movements of the body with normal excursion, strength, speed, coordination, and endurance. It is essential that the examination on which ratings are based adequately portray the anatomical damage and the functional loss with respect to all of these elements. In evaluating disabilities of the musculoskeletal system, it is necessary to consider, along with the schedular criteria, functional loss due to flare-ups of pain, fatigability, incoordination, pain on movement, and weakness. DeLuca v. Brown, 8 Vet. App. 202 (1995). The functional loss may be due to absence of part, or all, of the necessary bones, joints and muscles, or associated innervations, or other pathology and evidenced by visible behavior of the claimant undertaking the motion. Weakness is as important as limitation of motion, and a part that becomes painful on use must be regarded as seriously disabled. 38 C.F.R. § 4.40. Pain on movement, swelling, deformity or atrophy of disuse as well as instability of station, disturbance of locomotion, interference with sitting, standing and weight bearing are relevant considerations for determination of joint disabilities. 38 C.F.R. § 4.45. Painful, unstable, or misaligned joints due to a healed injury are entitled to at least the minimal compensable rating for the joint. 38 C.F.R. § 4.59. Under the General Rating Formula for Diseases and Injuries of the Spine, which applies to disabilities rated under Code 5242 (degenerative arthritis of the spine), a 40 percent rating requires limitation of forward flexion of the thoracolumbar spine to 30 degrees or less, or favorable ankylosis of the entire thoracolumbar spine. Note (1) to Diagnostic Code 5242 advises to evaluate any associated objective neurologic abnormalities, including, but not limited to, bowel or bladder impairment, separately under an appropriate diagnostic code. Note (5) states that, for VA compensation purposes, unfavorable ankylosis is a condition in which the entire cervical spine, the entire thoracolumbar spine, or the entire spine is fixed in flexion or extension, and the ankylosis results in one or more of the following: difficulty walking because of a limited line of vision; restricted opening of the mouth and chewing; breathing limited to diaphragmatic respiration; gastrointestinal symptoms due to pressure of the costal margin on the abdomen; dyspnea or dysphagia; atlantoaxial or cervical subluxation or dislocation; or neurologic symptoms due to nerve root stretching. Fixation of a spinal segment in neutral position (zero degrees) always represents favorable ankylosis. In addition, the Formula for Rating Intervertebral Disc Syndrome (IVDS) Based on Incapacitating Episodes, is applicable to the Veteran's degenerative disc disease of the cervical and lumbar spine, rated under Code 5243. Under that formula, a percent disability rating for IVDS with incapacitating episodes is warranted when the total duration of at least one week but less than 2 weeks during the past 12 months; a 20 percent disability rating for IVDS with incapacitating episodes is warranted when the total duration of at least 2 weeks but less than 4 weeks during the past 12 months; a 40 percent disability rating for IVDS with incapacitating episodes is warranted when the total duration of at least 4 weeks but less than 6 weeks during the past 12 months; and a 60 percent disability rating for IVDS with incapacitating episodes is warranted when the total duration is at least 6 weeks during the past 12 months. Note (1) to Diagnostic Code 5243 provides that, for purposes of ratings under Code 5243, an incapacitating episode is a period of acute signs and symptoms due to intervertebral disc syndrome that requires bed rest prescribed by a physician and treatment by a physician. Note (2) provides that, if IVDS is present in more than one spinal segment, provided that the effects in each spinal segment are clearly distinct, each segment is to be rated on the basis of incapacitating episodes or under the General Rating Formula for Diseases and Injuries of the Spine, whichever method results in a higher evaluation for that segment. Irritable bowel syndrome A zero percent rating is assigned for mild disturbances of bowel function with occasional episodes of abdominal distress. Moderate disability due to irritable bowel syndrome manifested by frequent episodes of bowel disturbance with abdominal distress warrants a 10 percent disability rating. A 30 percent rating for irritable bowel syndrome requires severe disability manifested by diarrhea or alternating diarrhea and constipation with more or less constant abdominal distress. 38 C.F.R. § 4.114, Code 7319. III. Analysis Spina bifida, discogenic low back pain, and lumbosacral strain In January 2007, the Veteran's attorney wrote that the Veteran was seeking an increased rating in his service- connected disabilities, indicating that each of the disabilities had become more severe. A 20 percent rating is currently in effect for the Veteran's service-connected low back disability. VA clinic records dated from May 2006 through March 2009 reflect the Veteran's periodic complaints of chronic low back pain. One note in November 2007 indicates that he underwent an epidural block in October 2007, and that his low back pain had subsequently shown significant improvement, although the pain had recently started increasing again. A VA compensation examiner in February 2007 noted the Veteran's complaint that "my whole spine seems to hurt" and that "my whole spine feels like something is grabbing (spine) and twisting it," with the pain intensity varying from 7-10/10. the Veteran indicated that the pain was worse with heavy lifting, walking, and working, and was helped by hot baths, heating pad, massage, sports cremes, and stretching. He denied any other pain or radiation, paresthesia, weakness, bowel or bladder complaints. The examiner stated that the Veteran could not relate any changes of pain or other symptoms over the previous several years. The Veteran stated that he would get "used to [the pain] after awhile" and that "I really don't pay that much attention to it anymore." He indicated that he would use a cane whenever he would leave the house, typically once a day, and that he could walk 2-3 blocks. The Veteran stated that he could manage his activities of daily living and normal household duties, but could not work, since he couldn't do any heavy lifting or walk long distances. On examination, there was no spinal deformity or asymmetry, muscle spasm, tenderness to palpation, heat, redness, or swelling. There was no evidence of abnormal weight-bearing. The examiner indicated that inspection of the tip of the Veteran's cane revealed almost no wear. Tested range of motion of the thoracolumbar spine revealed forward flexion to 30 degrees, extension to 30 degrees, lateral flexion to 20 degrees bilaterally, and lateral rotation to 30 degrees bilaterally. The Veteran reported that pain began at the stated limits of range of motion. The examiner noted that, while sitting in the examination room and other topics were being discussed, the Veteran was noted to spontaneously flex forward as much as 90 degrees without apparent pain or difficulty. There was no evidence of increased pain, fatigue, weakness, lack of endurance, or incoordination on repeated use, and no change in range of motion. The examiner stated that there was no objective or clinical evidence of additional limitation due to claimed flare-ups beyond the measured and reported ranges. The Veteran reported to an August 2007 VA compensation examiner that he had generalized muscle pain "from my feet to the top of my head" since his separation from service. He indicated that he could not work because of the pain and because he had difficulty sitting/standing more than 30-60 minutes or walking more than a couple blocks. The Veteran reported that he had had no specific evaluations or treatment. No lower extremity neurological complaints were voiced. The examiner noted only that range of motion testing was without pain or crepitation. She stated, however, that the Veteran was able to squat to the ground and could duck walk and recover. No abnormal neurological clinical findings were recorded. The examiner indicated that she found no objective evidence of low back pain, lumbosacral strain, or any sequelae of spina bifida occulta. There were no clinical findings to support the Veteran's claim of severe and unusual daily low back pain and bilateral lower extremity symptoms. The examiner stated that she found no objective findings that would indicate that the Veteran was disabled by low back pain, that he was unemployable, or that his low back disability had become more severe over time. She further commented that the Veteran's subjective history was vague and inconsistent, and on multiple occasions during the interview and examination that his response changed when a question was repeated later. At the time of an October 2008 VA compensation examination, the Veteran again described his low back pain as constant, with an intensity of 7/10. He indicated that flares would be precipitated by sneezing and lifting, although he could not say how much he could lift. The Veteran described the pain during a flare as 9/10, with a variable duration. He indicated that hydrocodone provided good relief. The Veteran denied any associated symptoms of numbness, weakness, bladder complaints, bowel complaints due to the low back pain, or erectile dysfunction. The examiner stated that the Veteran presented with a walking stick in hand, but noted that he was able to walk safely without the benefit of the cane. The Veteran reported that he could walk two blocks, and could stand for 15 minutes, sit 20 minutes; he denied any problem with balance or frequent falls. The examiner noted that there was no report of any incapacitating events in the previous 12 months. The examiner indicated that the Veteran presented leaning heavily on a walking stick, although during the examination his gait was even, his posture was erect, and his ambulation balance was steady. The Veteran was able to sit comfortably during the 30 minute examination, with few position changes for comfort. The examiner stated that range of motion measurements failed to match the known pathology. The Veteran demonstrated forward flexion to 30 degrees, but he was later able to bend over to put on his socks. The examiner also noted that seated straight leg raise testing yielded no complaints of pain. She indicated that, based on that information, she estimated the Veteran's true forward flexion to be 65-70 degrees at a minimum, extension to 30 degrees with pain, left lateral flexion to 30 degrees without pain, right lateral flexion to 25 degrees with pain, and lateral rotation to 30 degrees bilaterally without pain. The examiner stated that range of motion was partially limited by complaints of pain, but that there was no objective evidence of fatigue, spasms, weakness, or lack of endurance following repetitive use. She indicated that complaints of fatigue, weakness, and lack of endurance did not limit spine function any further than previously documented. There was no clinical or objective evidence of additional limitation due to claimed flare-ups beyond the measured and reported range. The Veteran also complained of localized tenderness on palpation of the low back and sacroiliac joints. But there was no guarding, and spinal contour was normal. Straight leg raise testing was negative. The neurological examination was essentially normal. Moreover, the examiner noted that the Veteran demonstrated good coordination during heel/toe and tandem walking, and was able to stand on one leg (right and left) while doing shallow knee bends, all without the use of his cane. The examiner's assessment was of mild degenerative joint disease and minimal degenerative disc disease of the lumbar spine that was unchanged since 2004. Because the record shows that the Veteran has not experienced any incapacitating episodes due to the low back disability, a separate rating under Code 5243 is not warranted. Similarly, because no examiner has reported any associated objective neurologic abnormalities, including bowel or bladder impairment, that are due to the low back disability, a separate rating is also not warranted on that basis. The Board observes that both the February 2007 and October 2008 VA compensation examiners initially reported measured forward flexion of the thoracolumbar spine to 30 degrees, at which point he complained of pain. However, both examiners also noted that, during other parts of the interview, the Veteran was able to flex much farther without difficulty or evidence of pain. Both of those examiners, as well as the August 2007 VA examiner, clearly seemed to indicate that the observed clinical findings did not support the Veteran's claim of severe low back pain. They felt that the amount of pain reported by the Veteran was out of proportion to the documented pathology. Put another way, all three examiners observed the Veteran to be exaggerating his symptoms during his physical examinations. He is being disingenuous during his examinations. The Board therefore chooses to focus on the range of motion findings that were casually observed or estimated as the true indication of his level disability. Because the February 2007 examiner noted that the Veteran was observed to flex as much as 90 degrees without pain and because the October 2008 examiner estimated the Veteran's true forward flexion to at least 65-70 degrees, the Board finds that the criteria are not met for a 40 percent rating under the provisions of the General Rating Formula. In addition, both the February 2007 and October 2008 examiners stated that there was no objective evidence of increased limitation of motion or function on repeated use or during flare-ups. Accordingly, no higher rating is warranted on that basis. See 38 C.F.R. §§ 4.40, 4.45; see also DeLuca v. Brown, 8 Vet. App. 202 (1995). For all the foregoing reasons, the claim for an increased rating for spina bifida occulta with discogenic low back pain and lumbosacral strain must be denied. In reaching this conclusion, the Board has considered the applicability of the benefit-of-the-doubt doctrine. However, as the preponderance of the evidence is against the appellant's claim, that doctrine is not applicable in the current appeal. 38 U.S.C.A. 5107(b); Gilbert v. Derwinski, 1 Vet. App. 49 (1991); Alemany v. Brown, 9 Vet. App. 518, 519 (1996). Irritable bowel syndrome In January 2007, the Veteran's attorney wrote that the Veteran was seeking an increased rating in his service- connected disabilities, indicating that each of the disabilities had become more severe. A zero percent rating is currently in effect for the service-connected irritable bowel syndrome. VA clinic records dated from May 2006 through March 2009 are generally silent for any complaints referable to irritable bowel syndrome. A report in November 2007 noted that the Veteran had had some diarrhea on several occasions. However, the diarrhea had disappeared after he stopping taking Cymbalta, a psychotropic medication. The Veteran reported to the February 2007 VA examiner that he had constant diarrhea ("loose stools) daily, two to three times per day, with occasional urgency. He stated that he felt like he may be "leaking" between bowel movements. He denied using pads or absorbent pants. The Veteran reported that he had epigastric pain lasting seconds three times a month or less, but he denied any other abdominal or pelvic pain. He denied passing any mucus or blood. The Veteran did not indicate that the disability had any effect on his daily activities. On examination, bowel sounds were normal. Epigastric tenderness was noted, but the abdomen was otherwise nontender to palpation and percussion. Rectal sphincter tone was normal and the perianal skin was entirely normal, with no dermatitis or irritation or other evidence of incontinence or chronic diarrhea. The examiner stated that she found no objective evidence of irritable bowel syndrome, reported diarrhea or associated fecal incontinence. She added that, although the Veteran had a history of epigastric pain most likely to due his non-service-connected gastroesophageal reflux disease (GERD), irritable bowel syndrome tends to present with lower abdominal tenderness. The examiner stated that she found no objective findings that would indicate that the Veteran was disabled by a bowel condition, that he was unemployable, or that his bowel disability had become more severe over time. The August 2007 VA examiner noted that the Veteran denied any melena, constipation, or diarrhea. She noted his previous diagnosis with GERD, with epigastric pain and treatment with Prilosec. On examination, the abdomen was nontender; no abnormal clinical findings were noted. The examiner's assessment did not include irritable bowel syndrome. The October 2008 VA compensation examiner noted that the Veteran couldn't say if he had lost any weight. There was no reported nausea or vomiting. The Veteran indicated that he had intermittent constipation when on narcotics for a long period. When asked if he ever had a normal stool, he replied, "I guess maybe once a week." He claimed diarrhea, but couldn't say how often during the day, noting that it was "variable." When asked whether he experienced incontinence episodes, he indicated that he did, and when asked how often, he couldn't say, maybe five times a month. The Veteran denied using pads and denied receiving any treatment for his claimed chronic diarrhea. When asked if he ever had abdominal pain, distress, or cramps, he replied, "sometimes." On examination, there was no evidence of malnutrition or other debility. The Veteran weighed 202 pounds; there was no evidence of weight loss. Bowel sounds were not hyperactive. There were no anal fissures, fistulas, hemorrhoids, or lesions in the perianal area. Sphincter tone was good; the rectal wall was smooth and nontender. The examiner noted that, of 255 entries in VA medical records, only two referred to diarrhea, and the only two notations of irritable bowel syndrome were the last two compensation examinations where irritable bowel syndrome was claimed. Although the Veteran has claimed that he has chronic diarrhea, up to three times per day, there is no evidence that he had ever received any treatment for chronic diarrhea. Nor is there any medical evidence of residuals of chronic diarrhea, such as weight loss or malnutrition. Moreover, each of the VA compensation examiners noted that there was no clinical evidence of any anal irritation, as would be expected in the case of chronic diarrhea. Further, the Veteran denied any other abdominal complaints, and the examiners also noted the absence of lower abdominal tenderness, as would be expected in irritable bowel syndrome. Indeed, given his proclivity to exaggerate his symptoms during his orthopedic examination, the Board has little doubt that the Veteran exaggerates his irritable bowel syndrome symptoms as well. Simply put, when considering the essentially asymptomatic findings of the examinations and virtually silent outpatient treatment records, the Board does not the Veteran to be truthful in his complaints. Accordingly, as suggested by the comments of each of the VA compensation examiners, the Board finds the Veteran's reports of chronic severe diarrhea not to be credible. There is no objective evidence of more than mild disability due to irritable bowel syndrome at any time during the appeal period as to warrant a 10 percent disability rating. For all the foregoing reasons, the claim for an increased rating for irritable bowel syndrome must be denied. In reaching this conclusion, the Board has considered the applicability of the benefit-of-the-doubt doctrine. However, as the preponderance of the evidence is against the appellant's claim, that doctrine is not applicable in the current appeal. 38 U.S.C.A. 5107(b); Gilbert v. Derwinski, 1 Vet. App. 49 (1991); Alemany v. Brown, 9 Vet. App. 518, 519 (1996). Extraschedular consideration In denying the claim for higher ratings, the Board also has considered whether the veteran is entitled to a greater level of compensation on an extra-schedular basis. Ordinarily, the VA Schedule will apply unless there are exceptional or unusual factors which would render application of the schedule impractical. See Fisher v. Principi, 4 Vet. App. 57, 60 (1993). According to the regulation, an extraschedular disability rating is warranted based upon a finding that the case presents such an exceptional or unusual disability picture with such related factors as marked interference with employment or frequent periods of hospitalization that would render impractical the application of the regular schedular standards. See 38 C.F.R. § 3.321(b)(1) (2009). An exceptional case is said to include such factors as marked interference with employment or frequent periods of hospitalization as to render impracticable the application of the regular schedular standards. See Fanning v. Brown, 4 Vet. App. 225, 229 (1993). Under Thun v. Peake, 22 Vet App 111 (2008), there is a three- step inquiry for determining whether a veteran is entitled to an extraschedular rating. First, the Board must first determine whether the evidence presents such an exceptional disability picture that the available schedular evaluations for that service-connected disability are inadequate. Second, if the schedular evaluation does not contemplate the claimant's level of disability and symptomatology and is found inadequate, the Board must determine whether the claimant's disability picture exhibits other related factors such as those provided by the regulation as "governing norms." Third, if the rating schedule is inadequate to evaluate a veteran's disability picture and that picture has attendant thereto related factors such as marked interference with employment or frequent periods of hospitalization, then the case must be referred to the Under Secretary for Benefits or the Director of the Compensation and Pension Service to determine whether, to accord justice, the Veteran's disability picture requires the assignment of an extraschedular rating. With respect to the first prong of Thun, the evidence in this case does not show such an exceptional disability picture that the available schedular evaluation for the service- connected low back disability or irritable bowel syndrome is inadequate. A comparison between the level of severity and symptomatology of the Veteran's low back disability and irritable bowel syndrome with the established criteria found in the rating schedule shows that the rating criteria reasonably describe the Veteran's disability level and symptomatology. The Board further observes that, even if the available schedular evaluation for the disability is inadequate (which it manifestly is not), the Veteran does not exhibit other related factors such as those provided by the regulation as "governing norms." The record does not show that the Veteran has required frequent hospitalizations for his back or bowel disabilities. Indeed, it does not appear from the record that he has been hospitalized at all for those disabilities. Additionally, there is not shown to be evidence of marked interference with employment due to those disabilities. The record does show that the Veteran has been found to be totally disabled by the Social Security Administration (SSA), due to the effects of chronic pain syndrome, status post right shoulder rotator cuff repair, bipolar disorder, a generalized anxiety disorder, and posttraumatic stress disorder. The SSA decision notes, however, that the Veteran's mental condition appeared to be the source of his most serious and debilitating limitations. There is nothing in the record which suggests that the disabilities of the low back and bowel in and of themselves markedly impacted his ability to perform his job. Moreover, there is no evidence in the medical records of an exceptional or unusual clinical picture. In short, there is nothing in the record to indicate that the service-connected disabilities on appeal cause impairment with employment over and above that which is contemplated in the assigned schedular ratings. See Van Hoose v. Brown, 4 Vet. App. 361, 363 (1993) [noting that the disability rating itself is recognition that industrial capabilities are impaired]. The Board therefore has determined that referral of this case for extra-schedular consideration pursuant to 38 C.F.R. 3.321(b)(1) is not warranted. ORDER An increased rating for spina bifida occulta, currently rated 20 percent disabling, is denied. An increased rating for irritable bowel syndrome, currently rated 0 percent disabling, is denied. REMAND In October 2008, the Veteran was afforded a VA compensation examination regarding his service-connected dysthymic disorder. That examiner, who had previously examined the Veteran for VA compensation purposes in September 2006 and January 2007, noted that there "appear[s] to be a number of different diagnoses suggested by different examining and treating sources," including bipolar II disorder, posttraumatic stress disorder (PTSD), and generalized anxiety disorder. The examiner indicated that those diagnoses did not appear to be supported by current signs and symptoms. He noted, however, that the Veteran had significant medical/physical complaints and that it was difficult to ascertain the degree to which his daily functioning was limited based solely on psychological factors. The examiner stated that the Veteran presented with a complex clinical picture and that, given the complexities of his complaints, as well as some conflict in the records, he suggested that an examination be conducted by a board of three examiners to resolve these conflicts. The examiner noted that the Veteran concurred with the suggestion and agreed to comply with another examination. The record indicates that a psychiatric examination by a board of three examiners was scheduled in June 2009. However, the Veteran canceled the examination, requesting that the location be transferred; he had apparently moved from Montana to North Dakota. In July 2009, the Veteran's file was transferred to the Fargo, North Dakota, RO, with the notation that an examination was needed. The record does not reflect that an examination by a board of three examiners has been rescheduled. In light of the statements by the October 2008 VA examiner, the Board finds that VA's duty to assist requires that another examination be scheduled. See 38 C.F.R. § 3.159(c)(4) (2009). The Court has held that when a determination on one issue could have a significant impact on the outcome of another issue, such issues are considered inextricably intertwined and VA is required to decide those issues together. Harris v. Derwinski, 1 Vet. App. 180 (1991). The claim of entitlement to a TDIU requires consideration of the effect on employability of all service-connected disabilities. The determination regarding the remanded issue of entitlement to an increased rating for the Veteran's service-connected dysthymic disorder could impact the Veteran's TDIU claim. See also Rice v. Shinseki, 22 Vet. App. 447, 453 (2009). The Board therefore finds these issues to be inextricably intertwined. Accordingly, the case is REMANDED for the following actions: 1. Schedule the Veteran for a psychiatric examination by a board of three examiners. The claims file, including a copy of this remand, must be reviewed by the examiners in conjunction with their examination. All testing found to be necessary by the examiners should be completed. The examiners' report should set forth in detail all current psychiatric symptoms, clinical findings, and diagnoses. Ask the examiners to provide the following medical opinions: a. For any diagnosis other than dysthymic disorder (for which service connection has been established), indicate whether that diagnosis represents a progression of the prior diagnosis, a correction of an error in the prior diagnosis, or the development a new and separate condition. b. For any disorder which is felt to constitute a new and separate condition, indicate the likelihood (i.e., 50 percent probability or greater) that that disorder is due to service or to a service-connected disability. c. Describe the effects that the service-connected psychiatric disability(ies) have on the Veteran's daily activities and on his ability to work. All opinions should be supported by adequate rationale. 2. Upon completion of the requested development, again consider the Veteran's claims for an increased rating for his dysthymic disorder and for a TDIU. If the claims are not granted to his satisfaction, furnish the Veteran and his attorney with a supplemental statement of the case (SSOC) and give them an opportunity to respond before returning the case to the Board. The appellant has the right to submit additional evidence and argument on the matter or matters the Board has remanded. Kutscherousky v. West, 12 Vet. App. 369 (1999). This claim must be afforded expeditious treatment. The law requires that all claims that are remanded by the Board of Veterans' Appeals or by the United States Court of Appeals for Veterans Claims for additional development or other appropriate action must be handled in an expeditious manner. See 38 U.S.C.A. §§ 5109B, 7112 (West Supp. 2009). ______________________________________________ MICHAEL A. HERMAN Acting Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
