VA Disability Claim Denied? What to Do Next With a Supplemental Claim

If your VA disability claim was denied, a supplemental claim is often the fastest way to fix it. In fiscal year 2025, veterans filed 685,669 Supplemental Claims (opens in new tab), and VA granted 48.2% of them.

This review asks VA to decide your VA disability claim again after you add new and relevant evidence. By the end of this guide, you will know why VA denied your claim, which evidence supports that denial, and how to file a supplemental claim before the deadline that protects your back pay.

Why was my VA disability claim denied?

Most denials mean VA did not find proof of one or more of the required elements. A denial in no way indicates that VA thinks you are not hurt. To grant service connection, VA needs three things: a current diagnosis; an in-service event, injury or exposure; and a medical link (the “nexus”) between them.

The most common reasons a VA disability claim is denied are:

• No current diagnosis: Symptoms were described, but no provider formally diagnosed the condition.
• No proof of an in-service event: Service records do not mention the injury, incident or exposure.
• No nexus: No medical reason can be found that connects your condition today to your service.
• A negative C&P exam opinion: The examiner determines that your condition was “less likely than not” related to service.
• A missed compensation and pension exam: VA denied the claim on the evidence it already had.
• A low rating: You were service-connected, but the rating understates how the condition limits you.

Your decision letter names the reason under “reasons for decision” and lists the evidence VA reviewed. Whatever is missing from that list is what your new filing has to supply.

What is a supplemental claim?

A supplemental claim is a request for VA to review a past decision on your VA disability claim (opens in new tab) because you have new and relevant evidence or a change in law now covers your condition. It is one of three decision review options created by the Appeals Modernization Act of 2017, and it is filed on VA Form 20-0995.

VA’s duty to assist applies here again. That means VA must help collect records you identify, including private records you authorize on VA Form 21-4142.

A change in law can also support the claim without new evidence. The PACT Act, for example, added more than 20 presumptive conditions (opens in new tab) for burn pit, Agent Orange, and other toxic exposures.

There is, however, one exception: if a rated condition has simply gotten worse, VA says to file a claim for increased compensation instead. If you have never claimed a condition, you file a VA disability claim for it on VA Form 21-526EZ (opens in new tab).

What counts as new and relevant evidence?

VA defines new evidence (opens in new tab) as information it has not considered before, and relevant evidence as information that proves or disproves something in your claim.

Supplemental Claim vs Higher-Level Review: Which should you choose?

You should choose a supplemental claim when the reason for denial is missing evidence. On the other hand, you should opt for a Higher-Level Review (HLR) when the evidence was already in your file but VA misread it. A Higher-Level Review cannot accept new evidence, which is why its grant rate has stayed about half that of the supplemental lane every year since 2019.

A Board Appeal puts your case before a judge, but it is the slowest path. If an HLR fails, you can still file another one afterward.

How long do you have to file a supplemental claim?

You can file a supplemental claim at any time, but filing within one year of your decision letter protects the effective date (opens in new tab) of your VA disability claim and your back pay. That one-year window is the most important date in your file.

If you think you are among the small handful using this route, you are not. Supplemental claim filings grew about 14-fold from fiscal 2019 to fiscal 2025, much of it after the PACT Act became law in August 2022.

The same one-year window applies after a Higher-Level Review or Board Appeal decision, so you can move between review options without losing your place.

How do you file a supplemental claim?

You file this claim using VA Form 20-0995 (opens in new tab) for disability compensation, or by mail, in person, or through an accredited representative for other benefits. This seven-step checklist makes the filing strong:

1. Read the “reasons for decision” in your decision letter and write down the elements or information VA said was missing.
2. Request your claims file and any exam report so you can see exactly what the examiner wrote.
3. Collect new and relevant evidence that answers each missing element.
4. Get a nexus letter from a doctor if the link to service was the problem. It should say the condition is “at least as likely as not” related to service, and explain why.
5. Complete VA Form 20-0995, listing each issue you are contesting and the date of the decision.
6. Add VA Form 21-4142 (opens in new tab) for any private records you want VA to collect.
7. Attend any C&P exam VA schedules, answer VA letters quickly, and track your VA disability claim on VA.gov (opens in new tab).

What happens after a C&P exam?

A compensation and pension exam, or C&P exam (opens in new tab), is a medical exam VA may order to gather facts for a VA disability claim, and VA may order another one after you request a decision review. The exam is only one step. Here is what happens after it:

1. The provider writes an exam report and sends it to VA. The provider cannot tell you the results at the time of the appointment.
2. VA reviews all the evidence in your file, including the exam report, your medical and service records, and statements from you and others.
3. VA makes a decision and mails you a decision letter. Timing depends on how complex the claim is and how many conditions you claimed.
4. To read the report yourself, request a copy on VA Form 20-10206 (opens in new tab), online, by mail, or in person.

If you miss the exam, VA may decide the claim based on the evidence it already has. VA can reschedule the exam (opens in new tab) for a genuine cause, such as a hospital stay or a death in your immediate family. If the report goes against you, a private medical opinion that answers the examiner’s reasoning is usually used as a fix in the next filing.

What evidence fixes a denied VA disability claim?

A successful filing answers the specific reason VA gave, providing evidence for every gap flagged.

The last row is the most crucial one for older denials. If your condition became presumptive after VA denied it, the change in law alone can support the claim.

What are the limits of a supplemental claim?

The problem with a supplemental claim is the uncertainty of the desired outcome it contains: In fiscal 2025, about half of these claims did not end in a grant (opens in new tab). A private medical opinion can cost money, and paid help needs care too. Only VA-accredited attorneys (opens in new tab) and claims agents may charge for claims work, and only after VA decides the initial claim. Unaccredited claim consultants have faced congressional scrutiny (opens in new tab), so it’s important to check any helper on VA’s accreditation search (opens in new tab) before you pay.

Mistakes that lead to an unsuccessful filing

• Resubmitting evidence VA already reviewed.
• Missing the one-year window and losing months of back pay.
• Sending a vague nexus letter that says “possibly” or gives no rationale.
• Adding evidence that does not answer the reason VA gave.
• Skipping a scheduled C&P exam.
