Those That


Currently, there are two categories of claims that can be granted secondary service connection under VA regulation 3.310, "Disabilities that are proximately due to, or aggravated by, service-connected disease or injury."


The first category includes claims for which there is an initial service-connected disability, and then a subsequent disability or disabilities found to be proximately due to (caused by) the service-connected disability. One example of this type of claim would be loss of limb due to amputation occurring subsequent to a service-connected diabetes diagnosis. The loss of a limb, it might be argued, should be service connected in addition to the diabetes because the amputation may not have been needed had the veteran not developed diabetes.


In accordance with a 1995 court decision (Allen v. Brown, 7 Vet. App. 439), VA will also grant service connection under this regulation in claims where there is an increase in the severity of nonservice-connected disability that is found to be due to aggravation by a service-connected disability. These are called secondary service connection by aggravation claims.
