If the VA denied a claim, a supplemental claim can reopen the issue for another look. But the key phrase in this process is “new and relevant evidence.” That phrase sounds simple until you are the one trying to decide whether a doctor’s note, a buddy statement, or a newly found record actually counts.
In general terms, new evidence is information the VA has not previously considered, and relevant evidence is information that tends to prove or disprove an issue in the claim. The current rule also says relevant evidence can include information that raises a new theory of entitlement that the VA did not address before. Those definitions come directly from the federal regulation governing supplemental claims and from the VA’s own explanation of the process in its decision-review materials (38 C.F.R. § 3.2501; VA Supplemental Claim page).
This distinction matters because a supplemental claim is not just a second chance to send the same file back in. It is a chance to present something meaningfully different that could affect the outcome. If you are still sorting out how this lane works overall, it may help to start with this broader overview of the supplemental-claim process.
In this post, you’ll learn what counts as new and relevant evidence, what usually does not count, common examples veterans use to support a supplemental claim, and why documented legal help can matter when the missing piece is not obvious from the denial letter.

The formal rule appears in 38 C.F.R. § 3.2501. It explains three points that often shape the entire strategy:
That last point is easy to miss, but it can be very important. Sometimes the problem is not that a veteran has no evidence. The problem is that the VA evaluated the wrong connection, or evaluated only one path to service connection when another path may exist. For example, a claim first argued as direct service connection may later be supported by evidence of secondary service connection, aggravation, toxic exposure, or a different in-service event.
The regulation also says the “new and relevant” standard is not intended to impose a higher threshold than the older “new and material” standard that used to govern reopened claims (38 C.F.R. § 3.2501; 38 C.F.R. § 3.156). In practical terms, that often means the evidence does not have to prove the entire case by itself. It often just has to matter in a way that could affect readjudication.
A supplemental claim can be filed at any time after notice of a VA decision, even after the issue becomes final. But timing still matters. The VA explains that filing within 1 year from the date on the decision letter may preserve the effective date in many situations, while filing later can affect retroactive benefits and continuous pursuit of the claim (VA decision review FAQs; 38 C.F.R. § 3.2500; 38 C.F.R. § 3.400).
That makes the evidence question more than a paperwork issue. It can affect:
The VA’s current website reports that the average time to complete a supplemental claim for disability compensation or pension benefits was 62.2 days in March 2026, although the agency notes a broader goal of 125 days for non-health-care supplemental claims (VA Supplemental Claim page). When the evidence is well targeted, that timeline can matter. When the evidence misses the issue identified in the denial, the process can drag out into another round of review.
