If a service-connected condition has gotten worse, the idea of asking VA for a higher disability rating can feel deceptively simple: fill out the form, explain the change, and wait. In real life, increased-rating claims often turn on what the file shows about severity, frequency, and day-to-day functional impact. VA disability ratings are built around average impairment in earning capacity, and VA looks at the evidence it has when deciding whether a higher evaluation fits the facts of a particular claim. See VA’s overview of disability ratings, 38 C.F.R. § 4.1, and 38 C.F.R. § 4.10.
In plain terms, a veteran who is asking VA to raise a rating is often trying to answer one core question: what evidence best shows the condition is worse now than it was when VA assigned the current rating?
That is where preparation matters.
This post explains what veterans often gather before filing for an increase, why each category can matter, and where gaps in the record can create problems later. If you want a broader explanation of how a worsened-condition claim works from start to finish, this guide on how re-evaluation requests usually work when a service-connected condition gets worse can help frame the bigger picture.

For an increased-rating claim, VA generally looks for evidence showing the current level of disability. That can include treatment records, examination findings, test results, lay statements, and information about how symptoms affect ordinary activity and work. VA’s evidence pages specifically recognize both medical evidence and lay evidence, including buddy statements, as part of the disability claims process. See VA’s evidence guidance for disability claims and the page for VA Form 21-10210, Lay/Witness Statement.
VA may also schedule a Compensation & Pension exam after the claim is filed. On its claim-exam page, VA notes that examiners may use condition-specific Disability Benefits Questionnaires and that veterans may submit new non-VA medical records before the appointment. See VA Claim Exam (C&P Exam).
That often means “proof” is not one document. It is usually a package of evidence that tells a consistent story.
Some veterans file first and collect records later. Others try to assemble a complete file on the front end. VA’s Fully Developed Claims program reflects the basic logic behind early preparation: when claimants submit relevant evidence together, VA may be in a better position to process the claim without as many avoidable delays.
For increased ratings, that kind of preparation can help in a few practical ways:
And there is another reason some veterans pause and gather materials first: VA has authority to request reexaminations when necessary to verify the current severity of a disability. That authority appears in 38 C.F.R. § 3.327. In general terms, asking VA to revisit a rating often places the current level of disability back under review, which is one reason many veterans prefer to understand the evidence picture before opening that process.
Before gathering anything else, many veterans start with the most recent VA rating decision, notification letter, and, if available, the code sheet showing the diagnostic code and current percentage.
