If VA increases my disability rating or adds another disability, when will my increased benefits be effective?
The effective date for your increased benefits will be the date VA receives your claim for an increase or a new disability.
NOTE: VA may award an earlier effective date for an individual evaluation of a current service-connected disability if the medical evidence reveals that there is an increase in the veteran's disability and a claim is received within one year.
For example, if there is medical evidence to show that the veteran's service-connected left knee arthritis was worse on June 13, 2005, and we receive a claim for an increased evaluation for the veteran's left knee arthritis on December 6, 2005, then the effective date for the increased evaluation will be June 13, 2005.
