Anyone heard of an era vet getting a claim napproved for diabetes after being out of service for a long time ?? I read this on the net and have been hearing that era vets are getting claims approved ??? Over time, court rulings and legislative actions have contributed to changes in the types of disability claims received by the VA. For instance, in 2000, Congress passed legislation making adult onset diabetes mellitus presumptive for all Vietnam veterans who served in-country. This has resulted in a large number of disability compensation awards for diabetes to Vietnam-era veterans .
