If I have major surgery, am I entitled to any benefits from VA? How will my benefits be affected? Will there be a temporary increase? What notification will the VA require and when? How long does the temporary benefit last? Veterans being treated for service-connected disabilities may be entitles to a temporary 100% rating for a period of convalescence. You should notify the VA when your surgery takes place. If you have medical evidence at that time, you may submit it, or you may notify VA of the provider of treatment so that we can obtain records. After a review of all available evidence, a decision will be made as to your entitlement to the 100% rate and the length of the convalescence period.
