Regardless of a veteran’s employment status or level of earnings, VA’s disability compensation program pays monthly cash benefits to eligible veterans who have service-connected disabilities resulting from injuries or diseases incurred or aggravated while on active military duty. A veteran starts the disability claims process by submitting a claim to one of the 57 regional offices administered by the Veterans Benefits Administration (VBA). In the average compensation claim, the veteran claims about five disabilities for which the regional office must develop the evidence required by law and federal regulations, such as military records and medical evidence. To obtain the required medical evidence, VBA’s regional offices often arrange medical examinations for claimants. For example, in fiscal year 2004, VBA’s 57 regional offices asked the 157 medical centers administered by the Veterans Health Administration (VHA) to examine about 500,000 claimants and provide examination reports containing the medical information needed to decide the claim. On the basis of the evidence developed by the regional office, an adjudicator determines whether each disability claimed by the veteran is connected to the veteran’s military service. Then, by applying medical criteria contained in VA’s Rating Schedule, the adjudicator evaluates the degree of disability caused by each service-connected disability in order to determine the veteran’s overall degree of service-connected disability. The degree of disability is expressed as a percentage, in increments of 10 percentage points—for example, 10 percent, 20 percent, 30 percent, and so on, up to 100 percent disability. The higher the percentage of disability, the higher the benefit payment received by the veteran. If a veteran disagrees with the regional office adjudicator’s decision on whether a disability is service-connected or on the appropriate percentage of disability, the veteran may file a Notice of Disagreement. The regional office then provides a further written explanation of the decision, and if the veteran still disagrees, the veteran may appeal to VA’s Board of Veterans’ Appeals. Before appealing to the board, a veteran may ask for a review by a regional office Decision Review Officer, who is authorized to grant the contested benefits based on the same case record that the original adjudicator relied on to make the initial decision. After appealing to the board, if a veteran disagrees with the board’s decision, the veteran may appeal to the U.S. Court of Appeals for Veterans Claims, which has the authority to render decisions establishing criteria that are binding on future decisions made by VA’s regional offices as well the board. For example, in DeLuca v. Brown, 8 Vet. App. 202 (1995), the court held that when federal regulations define joint and spine impairment severity in terms of limits on range of motion, VA claims adjudicators must consider whether range of motion is further limited by factors such as pain and fatigue during “flare-ups” or following repetitive use of the impaired joint or spine. Previous to this decision, VA had not explicitly considered whether such additional limitations existed because VA contended that its Rating Schedule incorporated such considerations. Because adjudicators often must use judgment when deciding disability compensation claims, variations in decision making are an inherent possibility. While some claims are relatively straightforward, many require judgment, particularly when the adjudicator must evaluate (1) the credibility of different sources of evidence; (2) how much weight to assign different sources of evidence; or (3) disabilities, such as mental disorders, for which the disability standards are not entirely objective and require the use of professional judgment. Without measuring the effect of judgment on decisions, VA cannot provide reasonable assurance that consistency is acceptable. At the same time, it would be unreasonable to expect that no decision-making variations would occur. Consider, for example, a disability claim that has two conflicting medical opinions, one provided by a medical specialist who reviewed the claim file but did not examine the veteran, and a second opinion provided by a medical generalist who reviewed the file and examined the veteran. One adjudicator could assign more weight to the specialist’s opinion, while another could assign more weight to the opinion of the generalist who examined the veteran. Depending on which medical opinion is given more weight, one adjudicator could grant the claim and the other could deny it. Yet a third adjudicator might conclude that the competing evidence provided an approximate balance between the evidence for and the evidence against the veteran’s claim, which would require that the adjudicator apply VA’s “benefit-of-the-doubt” rule and decide in favor of the veteran. An example involving mental disorders also demonstrates how adjudicators sometimes must make judgments about the degree of severity of a disability. The disability criteria in VA’s Rating Schedule provide a formula for rating the severity of a veteran’s occupational and social impairment due to a variety of mental disorders. This formula is a nonquantitative, behaviorally oriented framework for guiding adjudicators in choosing which of the degrees of severity shown in table 1 best describes the claimant’s occupational and social impairment. Similarly, VA does not have objective criteria for rating the degree to which certain spinal impairments limit a claimant’s motion. Instead, the adjudicator must assess the evidence and decide whether the limitation of motion is “slight, moderate, or severe.” To assess the severity of incomplete paralysis, the adjudicator must decide whether the veteran’s paralysis is “mild, moderate, or severe.” The decision on which severity classification to assign to a claimant’s condition could vary in the minds of different adjudicators, depending on how they weigh the evidence and how they interpret the meaning of the different severity classifications. Despite the inherent variation, however, it is reasonable to expect the extent of variation to be confined within a range that knowledgeable professionals could agree is reasonable, recognizing that disability criteria are more objective for some disabilities than for others. For example, if two adjudicators were to review the same claim file for a veteran who has suffered the anatomical loss of both hands, VA’s disability criteria state unequivocally that the veteran is to be given a 100 percent disability rating. Therefore, no variation would be expected. However, if two adjudicators were to review the same claim file for a veteran with a mental disability, knowledgeable professionals might agree that it would not be out of the bounds of reasonableness for these adjudicators to diverge by 30 percentage points but that wider divergences would be outside the bounds of reasonableness. The fact that two adjudicators might make differing, but reasonable, judgments on the meaning of the same evidence is recognized in the design of the system that VBA uses to assess the accuracy of disability decisions made by regional office adjudicators. VBA instructs the staff who review the accuracy of decisions to refrain from charging the original adjudicator with an error merely because they would have made a different decision than the one made by the original adjudicator. VBA instructs the reviewers not to substitute their own judgment in place of the original adjudicator’s judgment as long as the original adjudicator’s decision is adequately supported and reasonable. Because of the inherent possibility that different adjudicators could make differing decisions based on the same information pertaining to a specific impairment, we recommended in November 2004 that the Secretary of Veterans Affairs develop a plan containing a detailed description of how VA would (1) use data from a newly implemented administrative information system—known as Rating Board Automation 2000—to identify indications of decision-making inconsistencies among the regional offices for specific impairments and (2) conduct systematic studies of the impairments for which the data reveal possible inconsistencies among regional offices. VA concurred with our recommendation but has not yet developed such a plan. At this point, VA has now collected 1 full year of data using the new administrative data system, which should be sufficient to begin identifying variations and then assessing whether such variations are within the bounds of reasonableness. Because the existing medical records of disability claimants often do not provide VBA regional offices with sufficient evidence to decide claims properly, the regional offices often ask VHA medical centers to examine the claimants and provide exam reports containing the medical information needed to make a decision. Exams for joint and spine impairments are among the exams that regional offices most frequently request. To comply with the DeLuca decision’s requirements for joint and spine disability exam reports, VHA instructs its medical center clinicians to make not only an initial measurement of the range of motion in the impaired joint or spine but also to measure range of motion after having the claimant flex the impaired joint or spine several times. This is done to determine the extent to which repeated motion may result in pain or fatigue that further degrades the functioning of the impaired joint or spine. In addition, the clinician also is instructed to determine if the claimant experiences flare-ups from time to time, and if so, how often such flare- ups occur and the extent to which they limit the functioning of the impaired joint or spine. However, in a baseline study conducted in 2002, VA found that 61 percent of the exam reports on joint and spine impairments did not provide sufficient information on the effects of repetitive movement or flare-ups to comply with the DeLuca criteria. We reported earlier this month on the progress VA had made since 2002 in ensuring that its medical centers consistently prepare joint and spine exam reports containing the information required by DeLuca. We found that, as of May 2005, the percentage of joint and spine exam reports not meeting the DeLuca criteria had declined substantially from 61 percent to 22 percent. Much of this progress appeared attributable to a performance measure for exam report quality established by VHA in fiscal year 2004 after both VHA and VBA had taken a number of steps to build a foundation for improvement. This included creating the Compensation and Pension Examination Project Office, a national office established in 2001 to improve the disability exam process, and providing extensive training to VHA and VBA personnel. While VA made substantial progress in ensuring that its medical centers’ exam reports adequately address the DeLuca criteria, a 22 percent deficiency rate indicated that many joint and spine exam reports still did not comply with DeLuca.
