The date when the VA receives your claim regarding an increase or a new disability will be considered as the effective date for increased benefits. This is awarded by the VA on earlier dates only when private medical evidence proves the increased disability of the veteran. You can receive the claim within one year of the increased disability. For example, if there is medical evidence showing the veteran’s service-connected left knee arthritis was worse on June 13, 2009, and a claim for an increased evaluation for the veteran’s left knee arthritis is received on December 6, 2009, then the effective date for the increased evaluation will be June 13, 2009. Other information like treatment reports, admission dates for examination, or tests will be considered by VA when the information on the increase in disability is provided.
