VA Claims: How to File, Build Your Case, and Fight Back if You’re Denied
A VA disability claim is how you request compensation for a service-connected condition. Most claims are denied or underrated due to missing or weak evidence. Outcomes depend on how well your claim meets the VA’s requirements from the start.
This page covers the full process: filing, service connection, C&P exams, denials and appeals. Each section gives a high-level overview and links to deeper guides for that step.
Use the sections below to understand the process, then follow the links to focus on the exact step that matters for your claim.
Summary of Key Points
- Every VA claim requires a current diagnosis, an in-service event, and a medical nexus linking the two.
- The VA assigns ratings from 0% to 100% based on functional impairment, not just current diagnosis.
- C&P exams heavily influence decisions, and how you present symptoms directly affects your rating.
- Denied claims and low ratings can be challenged through multiple appeal lanes depending on the issue.
- Secondary and presumptive service connections can expand eligibility and increase your combined rating.

How the VA Claims Process Works
A claim begins when you file VA Form 21-526EZ and list your conditions. The VA gathers evidence, may schedule a C&P exam, and issues a rating decision.
Each condition is either service-connected and rated or denied. Multiple ratings are combined using the VA’s formula to determine your overall percentage and compensation.
Timelines vary, but here’s how long VA claims are taking right now. Additionally, claims with complete evidence submitted upfront move faster and are more likely to be decided correctly the first time.

Service Connection: The Foundation of Every Claim
Service connection is required for compensation. Without it, you can’t receive a VA rating.
You must show: a current diagnosis, an in-service event, and a medical nexus linking the two.
- Direct: Caused by an in-service event or exposure
- Secondary: Caused or worsened by a service-connected condition
- Presumptive: Automatically linked based on service criteria
Weak or missing nexus evidence is one of the most common reasons claims fail. A clear, well-supported medical opinion often determines the outcome.

Presumptive Claims
Presumptive claims don’t require a nexus. The VA already recognizes certain conditions as service-connected based on when and where you served.
The PACT Act of 2022 expanded eligibility for toxic exposures, including burn pits, Agent Orange, and Gulf War hazards.
To qualify, you must meet the service criteria and have a condition on the VA’s list.

How to File a VA Disability Claim
You can file using VA Form 21-526EZ online, by mail, in person, or through a VSO.
List each condition and submit supporting evidence at the time of filing, including:
- Service records
- Medical records
- Buddy statements
- Medical opinions
The VA will gather some records, but key evidence, especially nexus opinions, must be provided by you.

Compensation and Pension Exams
The VA often schedules a compensation & pension (C&P) exam to evaluate severity and, in some cases, service connection. The examiner’s report directly impacts your rating. Describe symptoms based on your worst days, not your best, and be specific about functional impact.
If the exam is inaccurate or unfavorable, you can challenge it with new evidence or a private medical opinion.

Understanding Your Rating Decision
The rating decision explains what was granted, denied, and why. It includes your ratings, effective date, and supporting rationale.
The VA combines ratings using its formula and rounds to the nearest 10%. This determines your compensation and eligibility for additional benefits.
Review your decision carefully. If the rating doesn’t match your symptoms or evidence, you can file for an increase or appeal the decision.

Denials and Appeals
A denial or low rating isn’t the final outcome. You have multiple appeal options:
- Supplemental Claim: Submit new and relevant evidence
- Higher-Level Review: Request a senior reviewer to reassess the same evidence
- Board of Veterans’ Appeals: Formal review with optional hearing and new evidence
The right lane depends on whether the issue is missing evidence or a VA error.

FAQs | Frequently Asked Questions
How long does a VA disability claim take?
Most claims take several months, but timelines vary based on complexity and evidence. As of March 2026, the average time to complete a VA disability claim is about 76.6 days.

Do I need a lawyer or VSO to file a VA claim?
No. You can file on your own. A VSO can assist at no cost and is often a good starting point. Attorneys and accredited agents are typically used for appeals, especially in more complex cases.
What is a nexus letter and do I need one?
A nexus letter is a medical opinion linking your condition to your military service. It is not required for presumptive conditions, but for most other claims, a strong nexus opinion is often the deciding factor.
What happens if I miss my C&P exam?
Missing a C&P exam can lead to a denial or a lower rating because the VA may decide your claim without key medical evidence. Contact the VA or the examiner immediately to reschedule.
Can I file for the same condition again after a denial?
Yes. A denial isn’t final. You can file a supplemental claim at any time with new and relevant evidence or choose another appeal lane depending on your situation.
What is the difference between a 0% rating and a denial?
A 0% rating means the VA granted service connection but assigned no compensation. A denial means service connection wasn’t established. A 0% rating still matters because it preserves the condition for future increases.
What is secondary service connection and how does it work?
Secondary service connection allows you to claim conditions caused or worsened by an existing service-connected disability. Each additional rated condition increases your combined rating and potential compensation.
What happens after the VA issues a rating decision?
You can accept the decision or appeal within one year. If you disagree, choose the appeal lane that fits your situation. You can also file for new conditions or an increase at any time.
