sbrewer, the only common denominator between disability ratings issued by a veteran's branch of service and the VA are the medical diagnositic codes used to identify the disability. As to who gives the higher percentage, Today it is very rare for VA do grant a lower percentage than the branch of service. However considering that the claim goes back 26 years it is possible. Have him file for an increase now w/ his VSO and then file a separate claim for CUE. Wait to get the increase first however because all work will stop on it so action can be taken on the CUE.
