Filing a VA disability claim can feel overwhelming — but it doesn't have to be. This guide walks you through every step of the process, from understanding service connection to surviving your C&P exam and appealing a denied claim. By the end, you'll know exactly what to do and what mistakes to avoid.
A VA disability claim is your formal request for the Department of Veterans Affairs to recognize a service-connected medical condition and compensate you for it. If you have a physical or mental health condition that was caused or worsened by your military service, you may be entitled to monthly tax-free payments, free VA healthcare, and other benefits.
In 2026, over 5 million veterans receive VA disability compensation. The average monthly payment ranges from $171 (10% rating) to over $3,700 (100% rating). Yet millions more veterans who qualify haven't filed — often because the process feels too complicated.
You do not need a lawyer or claims agent to file a VA disability claim. The process is free, and accredited VSO representatives can help you at no charge. claim.vet helps you prepare everything before you submit.
Service connection is the legal foundation of your claim. To receive VA disability compensation, you must prove three things:
Some conditions are presumptively service-connected — meaning the VA automatically assumes they're related to service without you having to prove it. These include conditions related to Agent Orange exposure, Gulf War illness, radiation exposure, and certain conditions for veterans who served in specific locations. Always check if your condition qualifies as presumptive first.
Strong evidence is the difference between approval and denial. Before you file, collect:
A nexus letter is one of the most powerful pieces of evidence you can submit. It's a written statement from a licensed medical professional — your personal doctor, a specialist, or a VA physician — that directly links your current medical condition to your military service.
A strong nexus letter will state that your condition is "at least as likely as not" caused by or aggravated by your military service. That "at least as likely as not" language (50% probability) is the legal standard the VA uses. Without a clear nexus, the VA will often deny the claim even if your condition is real and serious.
