Citation Nr: 1329642 Decision Date: 09/16/13 Archive Date: 09/20/13 DOCKET NO. 10-08 020 ) DATE ) ) On appeal from the Department of Veterans Affairs Regional Office in Reno, Nevada THE ISSUES 1. Entitlement to a disability rating in excess of 10 percent for herniated lumbar discs at L2-L3 and L4-S1 prior to December 6, 2011, and to a disability rating in excess of 40 percent from December 6, 2011. 2. Entitlement to a total disability rating based on individual unemployability (TDIU). REPRESENTATION Appellant represented by: National Association of County Veterans Service Officers WITNESS AT HEARING ON APPEAL Appellant ATTORNEY FOR THE BOARD D. Orfanoudis, Counsel INTRODUCTION The Veteran had active service from July 1984 to February 1988, from January 16 to January 23, 1991, and from September 2001 to May 2003. This matter comes before the Board of Veterans' Appeals (Board) on appeal from a December 2008 rating decision of the Department of Veterans Affairs (VA), Regional Office (RO), in Reno, Nevada, that continued a 10 percent disability rating for the Veteran's service-connected herniated lumbar disc at L2-3 and L4-S1. In September 2010, the Veteran testified at a video conference hearing over which the undersigned Acting Veterans Law Judge presided. A transcript of that hearing has been associated with his claims file. The provisions of 38 C.F.R. § 3.103(c)(2) impose two distinct duties on VA employees, including Board personnel, in conducting hearings: the duty to explain fully the issues and the duty to suggest the submission of evidence that may have been overlooked. Bryant v. Shinseki, 23 Vet. App. 488 (2010). During the hearing, the undersigned clarified the issue on appeal and inquired as to the nature and severity of the Veteran's asserted symptoms. The Veteran was offered an opportunity to ask the undersigned questions regarding his claim. The Board, therefore, concludes that it has fulfilled its duty under Bryant. This matter was previously before the Board in November 2011 and November 2012 wherein it was remanded for additional development. It is now returned to the Board. As will be discussed further herein, the Board finds that the agency of original jurisdiction (AOJ) substantially complied with the remand orders, and no further action is necessary in this regard. See D'Aries v. Peake, 22 Vet. App. 97, 105 (2008); Dyment v. West, 13 Vet. App. 141, 146-47 (1999) (remand not required under Stegall v. West, 11 Vet. App. 268 (1998), where the Board's remand instructions were substantially complied with), aff'd, Dyment v. Principi, 287 F.3d 1377 (2002). During the pendency of this appeal, by rating action dated in July 2012, the RO determined that the service-connected herniated lumbar disc at L2-3 and L4-S1 warranted a 40 percent disability rating, effective as of December 6, 2011. Applicable law provides that absent a waiver, a claimant seeking a disability rating greater than assigned will generally be presumed to be seeking the maximum benefit allowed by law and regulation, and that a claim remains in controversy where less than the maximum available benefits are awarded. AB v. Brown, 6 Vet. App. 35, 38 (1993). The Veteran has not withdrawn the appeal as to the issue of a disability rating greater than assigned, therefore, the issue remains in appellate status. The Board notes that during the pendency of this appeal, the Veteran was also awarded service connection for lumbar radiculopathy of the lower extremities, and that the disabilities have each been rated as 10 percent disabling, effective December 6, 2011, and 20 percent disabling effective February 28, 2013. The record before the Board does not reflect that the Veteran has disagreed the determinations. No appeal regarding the grant of service connection or the assigned disability ratings is before the Board at this time. The Board also notes that on VA examination in February 2013, the Veteran indicated that he was not able to work because of his low back disability. As it has been suggested that his disability impacts his ability to work, the Board finds that the issue of entitlement to a TDIU has been raised by the record. The United States Court of Appeals for Veterans Claims (Court) has held that a TDIU claim is part of an increased disability rating claim when such claim is raised by the record. See Rice v. Shinseki, 22 Vet. App. 447 (2009). The Court further held that when evidence of unemployability is submitted at the same time that the Veteran is appealing the rating assigned for a disability, the claim for TDIU will be considered part and parcel of the claim for benefits for the underlying disability. Id. As such, the issue has been included among those on appeal before the Board as captioned above. In addition to the paper claims file, there is a Virtual VA paperless claims file associated with the Veteran's claim. A review of the documents in such file reveals that the Virtual VA paperless claims file includes VA outpatient treatment records dated from December 2011 to December 2012 which the Board has considered herein. The remaining documents in the Virtual VA paperless claims file are either duplicative of the evidence in the paper claims file or are irrelevant to the issue on appeal. The issue of entitlement to a TDIU is addressed in the REMAND portion of the decision below and is REMANDED to the RO via the Appeals Management Center (AMC), in Washington, DC. FINDINGS OF FACT 1. Prior to December 6, 2011, the Veteran's herniated lumbar discs at L2-L3 and L4-S1 were manifested by pain in the lumbar spine with 90 degrees of flexion and 30 degrees of extension, lateral flexion, and lateral rotation; without incapacitating episodes for which a physician prescribed bed rest. 2. From December 6, 2011, the Veteran's herniated lumbar discs at L2-L3 and L4-S1, at worst, has been manifested by with 30 degrees of flexion, 5 degrees of extension, and 10 degrees of lateral flexion and lateral rotation; without incapacitating episodes for which a physician prescribed bed rest. CONCLUSIONS OF LAW 1. The criteria for a disability rating in excess of 10 percent for service-connected herniated lumbar discs at L2- L3 and L4-S1, prior to December 6, 2011, have not been met. 38 U.S.C.A. §§ 1155, 5103, 5107 (West 2002 & Supp. 2012); 38 C.F.R. §§ 4.1, 4.2, 4.3, 4.7, 4.14, 4.40, 4.45, 4.71a, Diagnostic Codes 5242, 5243 (2013). 2. The criteria for a disability rating in excess of 40 percent for service-connected herniated lumbar discs at L2- L3 and L4-S1, from December 6, 2011, have not been met. 38 U.S.C.A. §§ 1155, 5103, 5107 (West 2002 & Supp. 2012); 38 C.F.R. §§ 4.1, 4.2, 4.3, 4.7, 4.14, 4.40, 4.45, 4.71a, Diagnostic Codes 5242, 5243 (2013). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS VA's Duty to Notify and Assist The Veterans Claims Assistance Act of 2000 (VCAA), 38 U.S.C.A. §§ 5100, 5102-5103A, 5106, 5107, 5126 (West 2002 & Supp. 2012), 38 C.F.R. §§ 3.102, 3.156(a), 3.159 and 3.326(a) (2013), requires VA to assist a claimant at the time that he or she files a claim for benefits. As part of this assistance, VA is required to notify claimants of what they must do to substantiate their claims. 38 U.S.C.A. § 5103(a); 38 C.F.R. § 3.159(b)(1). VA must inform the claimant of any information and evidence not of record (1) that is necessary to substantiate the claim; (2) that the claimant is to provide; and (3) that VA will attempt to obtain. See Beverly v. Nicholson, 19 Vet. App. 394, 403 (2005). In addition, the notice requirements of the VCAA apply to all five elements of a service connection claim, including: (1) Veteran status; (2) existence of a disability; (3) a connection between the Veteran's service and the disability; (4) degree of disability; and (5) effective date of the disability. See Dingess/Hartman v. Nicholson, 19 Vet. App. 473 (2006). Specifically, the notice must include notice that a disability rating and an effective date for the award of benefits will be assigned if service connection is awarded. Id. at 486. By letters dated in February 2008, May 2009, November 2011, December 2011, February 2012, December 2012, and January 2013 the Veteran was notified of the evidence not of record that was necessary to substantiate his claims. He was told what information that he needed to provide, and what information and evidence that VA would attempt to obtain. He was also provided with the requisite notice with respect to the Dingess requirements. Under these circumstances, the Board finds that the notification requirements of the VCAA have been satisfied. For increased compensation claims, the VCAA requirement is generic notice, that is, the type of evidence needed to substantiate the claim, namely, evidence demonstrating a worsening or increase in severity of the disability and the effect that worsening has on employment, as well as general notice regarding how disability ratings and effective dates are assigned. See Vazquez-Flores v. Shinseki, 580 F. 3d 1270 (Fed. Cir. 2009); Wilson v. Mansfield, 506 F.3d 1055 (Fed. Cir. 2007). In this case, the Veteran was provided pertinent information in the above-mentioned letters and other correspondence provided by the AOJ. Specifically, VA informed the Veteran of the necessity of providing, on his own or by VA, medical or lay evidence demonstrating a worsening or increase in severity of his disability, and the effect that the worsening has on his employment and daily life. The Veteran was informed that should an increase in disability be found, a disability rating would be determined by applying the relevant diagnostic codes; and examples of pertinent medical and lay evidence that he could submit relevant to establishing entitlement to increased compensation. The Veteran was also provided notice of the applicable relevant diagnostic code provisions. Next, the VCAA requires that VA make reasonable efforts to assist the claimant in obtaining evidence necessary to substantiate a claim. The Veteran's relevant service, VA, and private medical treatment records have been obtained. There is no indication of any additional, relevant records that the RO failed to obtain. The Veteran has been medically evaluated. As noted above, this case was most recently remanded in November 2012 in order to obtain outstanding VA treatment records, to afford the Veteran the opportunity to identify additional private medical treatment records, to afford him an opportunity to identify alternative records, such as employment clinical records, earnings records, statements of other lay individuals, or other records that might substantiate his claim, and to afford him a VA examination so as to assess the severity of his low back disability. Thereafter, additional VA treatment records dated through December 2012 were associated with the Virtual VA claims file; in December 2012 the Veteran was notified of the opportunity to submit the above-stated additional records; and in February 2013, he was afforded a VA examination. Therefore, the Board finds that the AOJ has substantially complied with the November 2012 remand directives such that no further action is necessary in this regard. See D'Aries, supra. In sum, the Board finds that the duty to assist and duty to notify provisions of the VCAA have been fulfilled and no further action is necessary under the mandates of the VCAA. Increased disability ratings Disability ratings are intended to compensate impairment in earning capacity due to a service-connected disorder. 38 U.S.C.A. § 1155. Separate diagnostic codes identify the various disabilities. Id. It is necessary to rate the disability from the point of view of the Veteran working or seeking work, 38 C.F.R. § 4.2, and to resolve any reasonable doubt regarding the extent of the disability in the Veteran's favor. 38 C.F.R. § 4.3. If there is a question as to which disability rating to apply to the Veteran's disability, the higher rating 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. 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 (2013). 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 (2013); Peyton v. Derwinski, 1 Vet. App. 282 (1991). While the Veteran's entire history is reviewed when assigning a disability rating, 38 C.F.R. § 4.1, where service connection has already been established and an increase in the disability rating is at issue, it is the present level of disability that is of primary concern. Francisco v. Brown, 7 Vet. App. 55 (1994). Additionally, in determining the present level of a disability for any increased rating claim, the Board must consider the application of staged ratings. See Hart v. Mansfield, 21 Vet. App. 505 (2007). In other words, where the evidence contains factual findings that demonstrate distinct time periods in which the service- connected disability exhibited diverse symptoms meeting the criteria for different ratings during the course of the appeal, the assignment of staged ratings would be necessary. The assignment of a particular diagnostic code is "completely dependent on the facts of a particular case." See 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 current diagnosis and demonstrated symptomatology. Any change in a diagnostic code by VA must be specifically explained. Pernorio v. Derwinski, 2 Vet. App. 625 (1992). Words such as "moderate," "moderately severe," and "severe" are not defined in the Rating 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 (2013). Use of terminology such as "severe" by VA examiners and others, although evidence to be considered by the Board, is not dispositive of an issue. All evidence must be evaluated in arriving at a decision regarding an increased rating. 38 C.F.R. §§ 4.2, 4.6 (2013). It is possible for a Veteran to have separate and distinct manifestations from the same injury that would permit rating under several diagnostic codes; however, 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); 38 C.F.R. § 4.14 (2013) (precluding the assignment of separate ratings for the same manifestations of a disability under different diagnoses). 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 these elements. The functional loss may be due to absence of part, or all, of the necessary bones, joints and muscles, or associated structures, or to deformity, adhesions, defective innervation, or other pathology, or it may be due to pain, supported by adequate pathology and evidenced by visible behavior of the claimant undertaking the motion. Weakness is as important as limitation of motion, and a part which becomes painful on use must be regarded as seriously disabled. 38 C.F.R. §§ 4.10, 4.40, 4.45 (2013). VA must analyze the evidence of pain, weakened movement, excess fatigability, or incoordination and determine the level of associated functional loss in light of 38 C.F.R. § 4.40, which requires the VA to regard as "seriously disabled" any part of the musculoskeletal system that becomes painful on use. DeLuca v. Brown, 8 Vet. App. 202 (1995). Although pain may be a cause or manifestation of functional loss, limitation of motion due to pain is not necessarily rated at the same level as functional loss where motion is impeded. See Mitchell v. Shinseki, 25 Vet. App. 32 (2011); cf. Powell v. West, 13 Vet. App. 31, 34 (1999); Hicks v. Brown, 8 Vet. App. 417, 421 (1995); Schafrath v. Derwinski, 1 Vet. App. 589, 592 (1991). Pursuant to 38 C.F.R. §§ 4.40 and 4.45, the possible manifestations of functional loss include decreased or abnormal excursion, strength, speed, coordination, or endurance (38 C.F.R. §§ 4.40), as well as less or more movement than is normal, weakened movement, excess fatigability, and pain on movement (as well as swelling, deformity, and atrophy) that affects stability, standing, and weight-bearing (38 C.F.R. § 4.45). Thus, functional loss caused by pain must be rated at the same level as if the functional loss were caused by any of the other factors cited above. Therefore, in rating the severity of a joint disability, VA must determine the overall functional impairment due to these factors. When rating spine disabilities, the Board must discuss any additional limitation of motion that a Veteran has due to pain, weakness, or fatigue. See Cullen v. Shinseki, 24 Vet. App. 74, 85 (2011). The provisions of 38 C.F.R. § 4.14 (avoidance of pyramiding) do not forbid consideration of a higher rating based on greater limitation of motion due to pain on use, including during flare-ups. The guidance provided under DeLuca must be followed in adjudicating claims where a rating under the diagnostic code provisions governing limitation of motion should be considered. However, the provisions of 38 C.F.R. § 4.40 and 38 C.F.R. § 4.45, should only be considered in conjunction with the diagnostic code provisions predicated on limitation of motion. Johnson v. Brown, 9 Vet. App. 7 (1996). The intent of the rating schedule is to recognize painful motion with joint or periarticular pathology as productive of disability. It is the intention to recognize actually painful, unstable, or malaligned joints, due to healed injury, as entitled to at least the minimum compensable rating for the joint. 38 C.F.R. § 4.59 (2013). The Board notes that in Buie v. Shinseki, 24 Vet. App. 242 (2010), the Court held that even in increased rating claims, when VA receives a submission of new and material evidence within one year of a rating decision addressing the condition, 38 C.F.R. § 3.156(b) requires any subsequent decision to relate back to the original claim. Id. at 251- 52; see also Bond v. Shinseki, 659 F.3d 1362 (Fed. Cir. 2011). A review of the Veteran's claims file reveals that following the issuance of the September 2006 rating decision granting service connection for the Veteran's low back disability, there is no evidence received within one year which relates to any symptoms associated thereto. Thus, with respect to the Veteran's claim seeking an increased disability rating, the December 2008 rating action is the proper rating decision on appeal. The Veteran's herniated lumbar discs at L2-L3 and L4-S1 has been rated under 38 C.F.R. § 4.71a , Diagnostic Code 5243, which sets out the criteria for rating intervertebral disc syndrome. Intervertebral disc syndrome is rated based upon incapacitating episodes. Where incapacitating episodes manifest a total duration of at least one week but less than two weeks during the preceding 12 months, a 10 percent disability rating is warranted. Where incapacitating episodes have a total duration of at least two weeks but less than four weeks during the preceding 12 months, a 20 percent disability rating is warranted. With incapacitating episodes having a total duration of at least four weeks but less than six weeks during the preceding 12 months, a 40 percent disability rating is warranted. A maximum disability rating of 60 percent is assigned with incapacitating episodes having a total duration of at least six weeks during the preceding 12 months. It is noted that 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. 38 C.F.R. § 4.71a, Diagnostic Code 5243. As the Veteran has been diagnosed with degenerative disc disease of the low back, his disability may also be rated as degenerative arthritis of the spine under 38 C.F.R. § 4.71a , Diagnostic Code 5242. Under this diagnostic code provision, the disability is to be rated under the General Rating Formula for Diseases and Injuries of the Spine. Under the General Rating Formula for Diseases and Injuries of the Spine, a 10 percent disability rating is warranted for forward flexion of the thoracolumbar spine greater than 60 degrees but not greater than 85 degrees, or combined range of motion of the thoracolumbar spine greater than 120 degrees but not greater than 235 degrees, or muscle spasm, guarding, or localized tenderness not resulting in abnormal gait or abnormal spinal contour, or vertebral body fracture with loss of 50 percent or more of body height. A 20 percent disability rating is warranted for forward flexion of the thoracolumbar spine greater than 30 degrees but not greater than 60 degrees, or when the combined range of motion of the thoracolumbar spine is not greater than 120 degrees, or muscle spasm or guarding severe enough to result in an abnormal gait or abnormal spinal contour such as scoliosis, reversed lordosis, or abnormal kyphosis. A 40 percent disability rating is warranted for forward flexion of the thoracolumbar spine 30 degrees or less; or, favorable ankylosis of the entire thoracolumbar spine. A 50 percent disability rating is warranted for unfavorable ankylosis of the entire thoracolumbar spine. The maximum 100 percent disability rating is warranted for unfavorable ankylosis of the entire spine. 38 C.F.R. § 4.71a, Diagnostic Codes 5235 to 5243 (2013). Under the rating schedule, forward flexion to 90 degrees, and extension, lateral flexion, and rotation to 30 degrees, each, are considered normal range of motion of the thoracolumbar spine. 38 C.F.R. § 4.71a, General Rating Formula, Note 2, and Plate V (2013). Low Back Disability Prior to December 6, 2011 The Veteran's claim for an increased disability rating was received in January 2008. VA outpatient treatment records dated from January 2007 to November 2008 show that the Veteran was treated intermittently for symptoms associated with chronic low back pain for which he was treated with pain medication. A physical therapy note dated in December 2007 shows that there was limitation of flexibility in the trunk muscles with increased pain and decreased function with prolonged posture and activities at work. The Veteran was provided with a home program to build strength and flexibility in the core muscles. A VA examination report dated in November 2008 shows that the Veteran reported continued back pain with progressive limitation with daily activity. The Veteran reported experiencing decreased motion, weakness, spasms, and pain. He added that he would have moderate flare-ups with radiating pain every two to three weeks lasting 24 hours. The flare-ups would be alleviated with medication, stretching, relaxing, and laying down. He estimated an additional 50 percent limitation of motion and functional impairment during a flare-up. The Veteran reported that he had not had any incapacitating episodes of intervertebral disc syndrome requiring prescribed bed rest during the preceding 12 months. Physical examination revealed normal range of motion (90 degrees of flexion and 30 degrees of extension, lateral flexion, and lateral rotation). Combined range of motion of the thoracolumbar spine was 240 degrees. His gait was normal, and there was no alteration of spinal contour associated with spasms or guarding. On repetitive motion, he was observed to lose five to 10 degrees of motion on forward flexion due to lack of endurance. He reported that he had lost less than one week of work in the preceding year due to back pain. A magnetic resonance imaging (MRI) study obtained in October 2008 revealed mild degenerative changes of the lumbar spine with bulging discs. There was no noted ankylosis of the thoracolumbar spine. VA outpatient treatment records dated from November 2008 to August 2010 show that the Veteran continued to be treated for ongoing reported chronic low back pain. During his September 2010 hearing, the Veteran described experiencing pain, tenderness, and weakness in the low back. He indicated that his symptoms would be exacerbated by sitting still, standing, and walking. He also described having back spasms. He reported that he would treat his symptoms with two different medications. He stated that he walked with a limp as a result of his back disability. He added that he had not been prescribed bed rest for his low back disability since 2002. He also indicated that he had missed approximately one to two weeks of work since 2008 as a result of his low back disability. Having carefully considered the medical evidence of record, the Board finds that the Veteran's low back disability prior to December 6, 2011, does not meet the criteria for the assignment of the next higher 20 percent disability rating. The evidence of record, as detailed in pertinent part above, does not show a range of motion finding that warrants a disability rating greater than 10 percent under the General Rating Formula for Diseases and Injuries of the Spine. Specifically, in November 2008, the Veteran had 90 degrees of flexion and a combined range of motion of 240 degrees. As a result, the criteria for a compensable disability rating [let alone the next higher 20 percent (flexion of 30 to 60 degrees/combined range of motion of less than 120 degrees)] are not met. While the Veteran reported that he would experience occasional spasms, the medical evidence of record prior to December 6, 2011, did not demonstrate that the Veteran had muscle spasm or guarding that resulted in an abnormal gait or spinal contour such as scoliosis, reversed lordosis, or abnormal kyphosis. There is no medical evidence suggesting that motion was further limited by functional factors, even when taking into account any additional functional impairment due to pain, fatigue, or lack of endurance. See Mitchell, DeLuca; 38 C.F.R. §§ 4.40, 4.45. While the VA examiner in November 2008 indicated that repetitive motion resulted in an observed five to 10 degrees loss of forward flexion due to lack of endurance, this would still amount to 80 degrees of forward flexion which does not meet the criteria for the assignment of the next higher disability rating. While the Veteran clearly reports pain, pain is specifically contemplated in the rating assigned, 38 C.F.R. § 4.71a, and the medical evidence of record has not shown additional compensable functional impairment due to weakness and fatigue. Under Note (1) of the General Rating Formula, VA must consider whether combining ratings for orthopedic and neurological manifestations would result in a higher rating for the Veteran's service-connected lumbar spine disability. However, as noted in the introduction hereinabove, the Veteran has been awarded separate 20 percent disability ratings for neurological manifestations of each lower extremity, and such ratings are not currently on appeal before the Board. As a result, there is no evidence warranting additional separate, compensable disability ratings under this provision. Further, although the rating criteria sets forth rating criteria for intervertebral disc syndrome on the basis of incapacitating episodes, here, while the disability has been shown to involve intervertebral disc syndrome, it has not been shown that it has required prescribed bed rest at any point pertinent to this appeal. In this regard, the VA examiner in November 2008 indicated that the Veteran reported he had not had any incapacitating episodes of intervertebral disc syndrome requiring prescribed bed rest during the preceding 12 months. Additionally, during his September 2010 hearing, he reported that he had not had an incapacitating episode since 2002. While the Veteran has indicated that he has to rest on his back on occasion during a flare-up, there has been no indication in the record of physician-prescribed best rest, and this has been specifically denied on VA examination. The Board further finds that, since the date of the Veteran's claim for an increased disability rating until December 6, 2011, there was no additional distinct period of time during which the low back disability warranted a disability rating higher than that currently assigned. Accordingly, he is not entitled to receive an additional staged disability rating. See Hart, supra. The Board has considered the statements of the Veteran as to the extent of his current symptoms. He is certainly competent to report that his symptoms are worse. Layno v. Brown, 6 Vet. App. 465, 470 (1994). In evaluating a claim for an increased schedular rating, however, VA must consider the factors as enumerated in the rating criteria discussed above, which in part involves the examination of clinical data gathered by competent medical professionals. The preponderance of the evidence is against the claim of a disability rating higher than 10 percent for herniated lumbar discs at L2-L3 and L4-S1 prior to December 6, 2011, therefore, the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49 (1990). Low Back Disability From December 6, 2011 A VA examination report dated December 6, 2011, shows that the Veteran's entire claims file was reviewed by the examiner in conjunction with conducting the examination of the Veteran. The Veteran reported ongoing back pain for which he continued to take medication. He described a constant pain rated as a seven on a scale of 10. He added that medication would help reduce pain, but that he was never pain free. He also reported lower back muscle spasms lasting up to six to eight hours at night and up to an hour in the daytime. Physical examination revealed the ranges of motion of the thoracolumbar spine were measured as 30 degrees of forward flexion, with pain at zero degrees; 10 degrees of extension, with pain at zero degrees; 10 degrees of right and left lateral flexion, with pain at zero degrees; and 10 degrees of right and left lateral rotation, with pain at zero degrees. Following three repetitive movements, the ranges of motion of the thoracolumbar spine were the same. There was weakened movement, excess fatigability, pain on movement, instability of station, disturbance of locomotion, and interference with sitting, standing and/or weight-bearing. The Veteran had guarding or muscle spasm of the thoracolumbar spine severe enough to result in abnormal gait, abnormal spinal contour, such as scoliosis, reversed lordosis or abnormal kyphosis and guarding and/or muscle spasms. X-ray impressions from March 2011 revealed multilevel degenerative changes with most prominent finding of a left paracentral protrusion at the L4-5 level, causing significant mass effect on the traversing left-sided nerve roots as well as the exiting left L4 nerve root. The diagnosis was degenerative disc disease, lumbar neuritis associated with the thoracolumbar spine, and lower back pain. The examiner noted that the Veteran reported to have at least six weeks of incapacitating episodes over the preceding 12 months due to intervertebral disc syndrome that resulted in prescribed bed rest and treatment by a physician, however, this was not verified by the medical or employment records. A VA examination report dated in February 2013 shows that the Veteran reported that he had not undergone back surgery since his last VA examination. He added that he had been provided with a back brace for assistance, which he used for three weeks, but that that his pain instead had increased in severity. He continued to take pain medication for his symptoms. He described a constant pain rated as a seven or eight on a scale of 10. The pain would increase to a 10 for a total of two to three hours in a 24 hour period. Physical examination revealed ranges of motion for the thoracolumbar spine as 40 degrees of flexion; five degrees of extension; 10 degrees of right and left lateral flexion; and 10 degrees of right and left lateral rotation. The examiner added that the Veteran was able to perform repetitive-use testing with three repetitions with the same ranges of motion. The examiner noted that the thoracolumbar spine presented with less movement than normal, weakened movement, and incoordination. The examiner indicated that there was intervertebral disc syndrome, but without incapacitating episodes over the preceding 12 months. The diagnosis was degenerative disc disease with myelopathy. The VA examiner also clarified that according to the Veteran, he had never been prescribed bed rest and treatment by a physician while on bed rest in 2008, 2009, 2010, 2011, and 2012. He claimed that he would be in bed on some weekends when he was off work to rest his back. Having carefully considered the medical evidence of record, the Board finds that the Veteran's low back disability since December 6, 2011, does not meet the criteria for the assignment of the next higher 50 percent disability rating. The evidence of record, as detailed in pertinent part above, does not show that the Veteran's low back disability is manifested by unfavorable ankylosis of the entire thoracolumbar spine. As a result, the criteria for a higher disability rating under the General Rating Formula for Diseases and Injuries of the Spine are not met. There is no medical evidence suggesting that motion was further limited by functional factors, even when taking into account any additional functional impairment due to pain, fatigue, or lack of endurance. See Mitchell, DeLuca; 38 C.F.R. §§ 4.40, 4.45. In this regard, the VA examiners in December 2011 and February 2013 each indicated that following three repetitive movements, the ranges of motion of the thoracolumbar spine were the same. While the Veteran clearly reports pain, weakness, limitation of motion, spasms, and altered gait, such is specifically contemplated in the rating assigned, 38 C.F.R. § 4.71a, and the medical evidence of record has not shown additional compensable functional impairment rising to the level of ankylosis of the thoracolumbar spine. Additionally, as indicated above, VA must consider whether combining ratings for orthopedic and neurological manifestations would result in a higher rating for the Veteran's service-connected lumbar spine disability. However, the Veteran has been awarded separate 20 percent disability ratings for neurological manifestations of each lower extremity, and such ratings are not currently on appeal before the Board. As a result, there is no evidence warranting additional separate, compensable disability ratings under this provision. Further, although the rating criteria sets forth rating criteria for intervertebral disc syndrome on the basis of incapacitating episodes, here, while the disability has been shown to involve intervertebral disc syndrome, it has not been shown that it has required prescribed bed rest at any point pertinent to this appeal. In this regard, the VA examiner in November 2008 indicated that the Veteran reported he had not had any incapacitating episodes of intervertebral disc syndrome requiring prescribed bed rest during the preceding 12 months. Additionally, during his September 2010 hearing, he reported that he had not had an incapacitating episode since 2002. While the Veteran has indicated that he has to rest on his back on occasion during a flare-up, there has been no indication in the record of physician-prescribed best rest, and this has been specifically denied on VA examination. The Board further finds that, since December 6, 2011, there was no additional distinct period of time during which the low back disability warranted a disability rating higher than that currently assigned. Accordingly, he is not entitled to receive an additional staged disability rating. See Hart, supra. The Board has considered the statements of the Veteran as to the extent of his current symptoms. He is certainly competent to report that his symptoms are worse. Layno, 6 Vet. App. at 470. In evaluating a claim for an increased schedular rating, however, VA must consider the factors as enumerated in the rating criteria discussed above, which in part involves the examination of clinical data gathered by competent medical professionals. The preponderance of the evidence is against the claim of a disability rating higher than 40 percent for herniated lumbar discs at L2-L3 and L4-S1 from December 6, 2011, therefore, the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert, 1 Vet. App. at 53-56. Extra-schedular Consideration Finally, the Board finds that the Veteran's low back disability does not warrant referral for extra-schedular consideration. In exceptional cases where schedular ratings are found to be inadequate, consideration of an extra- schedular disability rating is made. 38 C.F.R. § 3.321(b)(1). There is a three-step analysis for determining whether an extra-schedular disability rating is appropriate. Thun v. Peake, 22 Vet. App. 111 (2008). First, there must be a comparison between the level of severity and symptomatology of the Veteran's service-connected disability and the established criteria found in the rating schedule to determine whether the Veteran's disability picture is adequately contemplated by the rating schedule. Id. If not, the second step is to determine whether the claimant's exceptional disability picture exhibits other related factors identified in the regulations as "governing norms." Id.; see also 38 C.F.R. § 3.321(b)(1) (governing norms include marked interference with employment and frequent periods of hospitalization). If the factors of step two are found to exist, the third step is to refer the case to the Under Secretary for Benefits or the Director of the Compensation and Pension Service for a determination whether, to accord justice, the claimant's disability picture requires the assignment of an extra-schedular rating. Id. The Board finds that the evidence does not warrant referral of the Veteran's claim for extra-schedular consideration. The level of severity of the Veteran's low back disability is adequately contemplated by the applicable diagnostic criteria. The criteria provide for a higher rating, but as has been thoroughly discussed above, the rating assigned herein is appropriate. In view of the adequacy of the disability rating assigned under the applicable diagnostic criteria, consideration of the second step under Thun is not for application in this case. Accordingly, the claim will not be referred for extra-schedular consideration. ORDER A disability rating in excess of 10 percent for herniated lumbar discs at L2-L3 and L4-S1 prior to December 6, 2011, is denied. A disability rating in excess of 40 percent for herniated lumbar discs at L2-L3 and L4-S1 from December 6, 2011, is denied. REMAND Unfortunately, a remand is required in this case as to the issue of entitlement to a TDIU. Although the Board sincerely regrets the additional delay, it is necessary to ensure that there is a complete record upon which to decide the Veteran's claim so that he is afforded every possible consideration. VA has a duty to make reasonable efforts to assist the claimant 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 claim. 38 U.S.C.A. § 5103A(a) (West 2002 & Supp. 2012); 38 C.F.R. § 3.159(c), (d) (2013). The Veteran contends that his service-connected low back disability precludes him from engaging in substantially gainful employment consistent with his education and his occupational experience. A Veteran will be entitled to a TDIU upon establishing an inability to secure or follow a substantially gainful occupation due solely to impairment resulting from service- connected disabilities. See 38 U.S.C.A. § 1155; 38 C.F.R. §§ 3.340, 3.341, 4.15, 4.16. Consideration may be given to the level of education, any special training, and previous work experience in making this determination, but not to age or impairment from disabilities that are not service connected (i.e., unrelated to military service). See 38 C.F.R. §§ 3.341, 4.15, 4.16, 4.19. To qualify for a total disability rating for compensation purposes, the evidence must show (1) a single disability rated as 100 percent disabling; or (2) that the Veteran is unable to secure or follow a substantially gainful occupation as a result of service-connected disabilities - provided there is one disability ratable at 60 percent or more, or, if more than one disability, at least one disability ratable at 40 percent or more and a combined disability rating of 70 percent. 38 C.F.R. § 4.16(a). While the regulations do not provide a definition of "substantially gainful employment," VA Adjudication Procedure Manual, M21-1, Part VI, paragraph 7.09(a)(7), defines the term as "that which is ordinarily followed by the nondisabled to earn their livelihood with earnings common to the particular occupation in the community where the Veteran resides." Also, in Faust v. West, 13 Vet. App. 342 (2000), the Court defined "substantially gainful employment" as an occupation that provides an annual income that exceeds the poverty threshold for one person, irrespective of the number of hours or days that the Veteran actually works and without regard to the Veteran's earned annual income . . ." In Moore v. Derwinski, 1 Vet. App. 356, 359 (1991), the Court also discussed the meaning of "substantially gainful employment." In this context, the Court noted the following standard announced by the United States Court of Appeals for the Federal Circuit (Federal Circuit) in Timmerman v. Weinberger, 510 F.2d 439, 442 (8th Cir. 1975): It is clear that the claimant need not be a total 'basket case' before the Courts find that there is an inability to engage in substantial gainful activity. The question must be looked at in a practical manner, and mere theoretical ability to engage in substantial gainful employment is not a sufficient basis to deny benefits. The test is whether a particular job is realistically within the physical and mental capabilities of the claimant. Marginal employment, for example, as a self-employed worker or at odd jobs or while employed at less than half of the usual remuneration, shall not be considered "substantially gainful employment." 38 C.F.R. § 4.16(a). See, too, Moore (Robert) v. Derwinski, 1 Vet. App. 356, 358 (1991). That is, a Veteran may be considered as unemployable upon termination of employment that was provided on account of disability or in which special consideration was given on account of the same. See 38 C.F.R. § 4.18. To receive a TDIU, the Veteran's service-connected disabilities, alone, must be sufficiently severe to cause unemployability. Hatlestad v. Brown, 5 Vet. App. 524, 529 (1993). In this case, the Veteran currently meets the minimum percentage requirements for a TDIU set forth in 38 C.F.R. § 4.16(a). However, it remains unclear whether the Veteran is prevented from engaging in substantially gainful employment as a result of his service-connected disabilities. In this regard, on VA examination in February 2013, the VA examiner indicated that based on the diagnoses, the Veteran could not perform heavy labor work, but could perform light labor and sedentary duty. The examiner added that the Veteran could not perform jobs that required bending and heavy lifting. The examiner then stated that the Veteran could not perform jobs that required sitting, standing, or walking more than 15 minutes at a time due to back pains. As the examiner in one statement suggests that the Veteran can undertake light labor and sedentary work, and in another statement suggests that the Veteran cannot work in a job requiring sitting, standing, or walking more than 15 minutes at a time, it remains unclear to the Board whether the Veteran can actually engage in substantially gainful employment. As such, on remand, the Veteran should be afforded a VA examination in order to obtain an opinion as to whether the service-connected disabilities have impacted his ability to work. See Friscia v. Brown, 7 Vet. App. 294, 297 (1994). Accordingly, the case is REMANDED for the following action: 1. The RO/AMC shall schedule the Veteran for a VA examination to determine whether his service-connected disabilities, either alone or in combination, prevent him from securing or following employment for which his education and occupational experience would otherwise qualify him. The claims file, including this remand, must be sent to the examiner for review; consideration of such should be reflected in the completed examination report. The examiner is requested to determine whether the Veteran is currently working. If not, the examiner shall opine as to whether it is at least as likely as not that the Veteran's service-connected disabilities, either alone or in combination, preclude him from securing or following substantially gainful employment for which his education and occupational experience would otherwise qualify him. The examiner must provide reasons for the opinion. If the examiner is unable to provide an opinion without resort to speculation, he or she should explain why this is so and what, if any, additional evidence would be necessary before an opinion could be rendered. The examiner is advised that the Veteran is competent to report his symptoms and history and such reports must be specifically acknowledged and considered in formulating any opinions. If the examiner rejects the Veteran's reports, the examiner must provide a reason for doing so. 2. The RO/AMC will then review the Veteran's claims file and ensure that the foregoing development actions have been conducted and completed in full, and that no other notification or development action, in addition to those directed above, is required. If further action is required, it should be undertaken prior to further claim adjudication. 3. The RO/AMC will then readjudicate the Veteran's claim. If the benefit sought on appeal remains denied, the Veteran and his representative should be provided with a Supplemental Statement of the Case. An appropriate period of time should be allowed for response. Thereafter, if appropriate, the case is to be returned to the Board, following applicable appellate procedure. The Veteran need take no action until he is so informed. He 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). The purposes of this remand are to obtain additional information and comply with all due process considerations. No inference should be drawn regarding the final disposition of this claim as a result of this action. 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. 2012). ______________________________________________ Thomas H. O'Shay Acting Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
