Filing for a higher VA disability rating can sound simple: your service-connected condition got worse, so you ask VA to increase the percentage. In practice, a lot of increased-rating claims become harder than they look because the file does not fully show how the condition worsened, how often symptoms happen, and how those symptoms affect day-to-day functioning.
That gap matters. VA assigns disability ratings based on severity, using the evidence you submit, the results of any VA claim exam, and other information VA gathers. VA’s rating regulations also focus on the full disability picture, including functional impairment and whether the evidence more nearly matches the criteria for the next higher evaluation. VA explains its rating process here and the governing regulations appear in 38 C.F.R. Part 4, including § 4.7 and § 4.10.
In this post you’ll learn how to file for an increased rating without underdeveloping the evidence: what to gather before filing, how to match proof to the rating criteria, where veterans often leave the record too thin, and when an attorney may help uncover evidence that changes the conversation. If you want a broader overview first, it may help to start with this guide to how worsening conditions and re-evaluations usually work.

An increased-rating claim is not just a statement that symptoms got worse. It is a claim that the current level of impairment now fits a higher evaluation under VA’s rating schedule.
VA says a worsening condition generally belongs in an increased-compensation claim, not a Supplemental Claim. On the other hand, a Supplemental Claim is used when a prior decision is being revisited with “new and relevant” evidence. VA draws that distinction here. That distinction can affect both procedure and evidence strategy.
Evidence often becomes underdeveloped when the file includes one or more of these problems:
VA can decide some claims based on the records alone through the Acceptable Clinical Evidence process, but if the record is incomplete, VA may schedule a C&P exam instead. Either way, the core issue stays the same: the evidence has to tell a detailed, usable story.
The first step is procedural, but it affects the substance of the case.
VA states that if you already have a disability rating for a condition and it has gotten worse, the path is a claim for increased disability compensation rather than a Supplemental Claim based on “new and relevant” evidence. VA says that directly here. That matters because some veterans end up using the wrong lane and then spend months dealing with avoidable delays.
This is also where timing becomes important. If the worsening happened after the last decision, the evidence may need to show when the increase in severity began, not just that the condition is bad now. In general terms, a more complete timeline can make it easier to evaluate both the current rating issue and any questions about the proper effective date.
