How to File a VA Disability Claim
Filing a VA disability claim means proving three things: a current diagnosis, an in-service event, and the link between them. Start with an intent to file to protect your effective date, choose between a Fully Developed Claim and a standard claim, attend the C&P exam, and know your three appeal lanes if the decision disappoints.
This guide is a general overview of the process, not legal or benefits advice. Every claim is different, and free help is available from Veterans Service Organizations and accredited representatives. Nothing here replaces their guidance or the instructions on va.gov.
Step 1: File an intent to file
Before you assemble anything, consider submitting an intent to file. This is a formal notice to the VA that a claim is coming. It holds your effective date for up to one year. If the claim is granted, your back pay can reach back to the intent-to-file date, not just the date you finally submitted everything. That single step can be worth thousands of dollars, and it costs nothing. You can submit it online at va.gov, by phone, or on paper.
Step 2: Understand what the VA needs to see
A granted claim generally rests on three elements. First, a current medical diagnosis: you need a condition a clinician has actually diagnosed, not just symptoms you describe. Second, an in-service event, injury, illness, or aggravation: something that happened during your service, documented in your service treatment records if possible. Third, a nexus, which is the medical link connecting the current condition to the in-service event.
The strongest claims make all three obvious. Your service treatment records show the in-service event. Your current medical records show the diagnosis and ongoing treatment. A nexus letter from a qualified clinician, or a well-written personal statement connecting the timeline, bridges the two. Lay evidence counts too: statements from fellow service members, spouses, or family describing what they observed can support the record, especially for conditions like PTSD or hearing loss where the paper trail is thin.
Step 3: Pick your claim lane
The VA offers a few ways to file. A Fully Developed Claim means you submit all your evidence up front and certify there is nothing more to gather. Because the VA does not have to go hunting for records, these claims are typically decided faster. A standard claim lets the VA help gather records, such as federal treatment records, but it usually takes longer.
There are also special paths. Veterans filing within a year of discharge can use the Benefits Delivery at Discharge program. If you are filing for an increase in an already service-connected condition, that is an increased claim. If you are filing for a condition secondary to a service-connected one, such as sleep apnea secondary to PTSD, that is a secondary claim, and it needs its own nexus showing the secondary condition was caused or aggravated by the primary one.
Step 4: Submit the claim
You can file online at va.gov, which is the fastest route for most veterans, or by mail, by fax, or in person at a regional office. List every condition you are claiming, and be specific: name the body part and the diagnosis as your records show it. Vague entries slow things down. Attach your evidence: service treatment records, private medical records, nexus letters, and lay statements. Keep copies of everything you send.
While the claim is pending, keep going to medical appointments and keep records current. Gaps in treatment get noticed. If a condition worsens while you wait, document it, because you can support the claim with updated evidence before the decision.
Step 5: Attend the C&P exam
Most claims trigger a Compensation and Pension exam, a medical evaluation the VA schedules to assess your conditions. It is not treatment; it is an assessment. The examiner reviews your records, examines you, and answers the VA's questions about diagnosis, severity, and service connection. Show up, be honest, and describe your worst typical days, not your best. Veterans sometimes minimize their symptoms out of habit, and the exam is the wrong place for that. Bring a list of your conditions, medications, and how each condition limits your daily life and work.
Step 6: Read the decision letter carefully
The VA issues a rating decision that grants or denies each claimed condition and assigns a percentage to each granted one. It also states your combined rating and your effective date. Read the whole letter, including the reasons section. It tells you exactly what evidence the VA relied on and what was missing, which is the roadmap for your next move.
Check the combined rating with our VA disability calculator to make sure the math matches the whole-person formula. The VA's figure is official, but verifying it yourself catches errors and teaches you how future ratings will move your total.
If the answer is no, or too low
A denial or a low rating is not the end. You have three appeal lanes, and you generally have one year from the decision to choose one. A Supplemental Claim lets you submit new and relevant evidence that was not in the record before. A Higher-Level Review sends the existing record to a more senior reviewer with no new evidence allowed, which suits cases where you believe the VA made an error on the evidence it had. An appeal to the Board of Veterans Appeals offers several dockets, including a hearing option, for the most contested cases.
Picking the right lane matters, and this is where a VSO or accredited claims agent earns their keep. They do this every day, they know which lane fits which fact pattern, and their help is free. Organizations like the DAV, VFW, American Legion, and state veterans agencies all provide accredited representatives.
Common mistakes to avoid
The most expensive mistakes are all avoidable. Do not skip the intent to file. Do not file with no evidence and hope the VA finds it all. Do not miss the C&P exam or downplay your symptoms there. Do not assume the VA knows about your dependents; file VA Form 21-686c separately. And do not let a denial sit past the one-year appeal window. A methodical claim, filed with complete evidence and followed through the exam, gives the VA every reason to say yes.
