After the VA issues a decision on a disability claim, you generally have 1 year from the date on the decision letter to keep the claim alive — by filing a Supplemental Claim (VA Form 20-0995), a Higher-Level Review (VA Form 20-0996), or a Notice of Disagreement to the Board (VA Form 10182). Let the year lapse and the decision becomes final; you would have to start over with a new claim and usually lose the earlier effective date (and back pay).
Filing within 1 year preserves your original effective date for back pay. Separately, filing your INITIAL claim within 1 year of separation from service can set the effective date back to your discharge date. There is no deadline to file a first disability claim, but waiting costs back pay. Confirm dates on VA.gov or with an accredited VSO/attorney.
Missing the statute of limitations usually ends your case permanently. Talk to a va disability decision appeal attorney—most offer a free consultation.
