Post-traumatic stress disorder (PTSD) was officially recognized as a disorder by the American Psychiatric Association in January 1980, and the Veterans Administration (VA) started processing veterans' claims for the disorder in October 1980. To investigate allegations that the Buffalo VA Regional Office was disapproving a high percentage of claims based on PTSD, not processing claims in a timely manner, awarding initial rating levels that were too low, and not providing due process to PTSD claimants, 32 PTSD cases were reviewed. The results revealed that: (1) statistical data on rating levels for PTSD cases were not available; (2) of the 32 cases reviewed, 19 were approved by the Buffalo Office to receive benefits, 4 were granted benefits by the Board of Veterans Appeals, 8 had been denied by Buffalo and were in the appeals process, and 1 case was denied and closed; (3) the 23 cases receiving benefits had a weighted average rating at the 40-percent degree of disability level and an initial weighted-average rating at the 30-percent level; (4) the Buffalo Office practice for deciding whether to request a psychiatric examination resulted in delay in processing claims; and (5) of 21 decisions rendered by the Board of Veterans Appeals for the 32 cases, none resulted in a return of the case to the Buffalo Office for lack of due process. Corrective actions which Buffalo Office officials have taken or agreed to take should reduce the processing time for PTSD claims. (NB)
