The Complete Guide to VA Disability Claims

What Is a VA Disability Claim?

A VA disability claim is a formal request to the U.S. Department of Veterans Affairs for compensation related to injuries, diseases, or conditions that were caused or aggravated by military service. If the VA grants your claim, you receive a monthly tax-free payment based on your disability rating (0% to 100%).

As of 2026, over 4.7 million veterans receive VA disability compensation, with the VA paying out more than $15 billion monthly. Despite this, the Government Accountability Office (GAO) has repeatedly found that many veterans are underrated or unaware of benefits they’ve earned.

To receive VA disability compensation, you must establish three things:

1. A current diagnosed condition — You must have a medical diagnosis of the condition you are claiming.
2. An in-service event, injury, or illness — Something happened during your military service that is connected to your condition.
3. A medical nexus — A medical opinion (nexus letter) connecting your current condition to the in-service event.

Types of VA Disability Claims

Original Claim (Initial Claim)

This is the first claim you file for a particular condition. You can file an original claim at any time after separation from service — there is no statute of limitations. However, the effective date (and therefore back pay) is typically based on when you file, so filing sooner is generally advantageous.

File an original claim using VA Form 21-526EZ, either online through VA.gov, by mail, or in person at a VA regional office.

Supplemental Claim

If your claim was previously denied, a Supplemental Claim allows you to submit new and relevant evidence that wasn’t available during the original decision. This is often the most effective path after a denial because it gives you a fresh review with new evidence.

Key requirement: You must submit at least one piece of new and relevant evidence. A new nexus letter, updated medical records, or a buddy statement can qualify.

Claim for Increase

If your service-connected condition has worsened since your last rating, you can file a claim for increase. The VA will schedule a new Compensation & Pension (C&P) exam to reassess the severity.

Secondary Service Connection

A secondary claim is for a condition caused by or aggravated by a condition you are already service-connected for. For example, if your service-connected knee injury causes you to develop a back condition due to altered gait, the back condition may be secondary service-connected. See our detailed section below.

Evidence Requirements

The strength of your claim depends entirely on the quality and completeness of your evidence. The VA uses the “benefit of the doubt” doctrine (38 U.S.C. § 5107(b)) — if the evidence is roughly equal for and against your claim, the VA must decide in your favor.

Types of evidence the VA considers:

• Service Treatment Records (STRs) — Medical records from your time in service documenting injuries, illnesses, or complaints.
• VA Medical Records — Treatment records from VA healthcare facilities.
• Private Medical Records — Records from civilian doctors, specialists, or hospitals.
• Nexus Letters — A medical opinion letter from a qualified provider stating that your condition is “at least as likely as not” related to your military service.
• Buddy Statements (Lay Evidence) — Written statements from fellow service members, family, or friends describing what they witnessed.
• Personnel Records — DD-214, deployment records, awards, MOS documentation.

The C&P Exam (Compensation & Pension Exam)

After you file a claim, the VA will likely schedule a C&P exam. This is a medical evaluation conducted by a VA-contracted examiner to assess the current severity of your condition and whether it is related to your service.

Critical tips for your C&P exam:

• Don’t downplay symptoms. Describe your worst days, not your best. The examiner assesses your condition at its worst.
• Be honest and thorough. Discuss every symptom, even ones that seem minor. Mention how the condition affects your daily life and work.
• Bring documentation. Bring copies of your medical records, nexus letters, and buddy statements to the exam.
• Document the exam. Write down what happened during the exam immediately afterward, including what questions were asked and how long it lasted.
• Don’t be stoic. Many veterans minimize their symptoms out of habit. The C&P exam is not the time for that.

Timeline & What to Expect

The average VA claim takes approximately 125–150 days to process, though complex claims can take longer. Here’s a typical timeline:

1. Claim Submission — File via VA.gov, mail, or in person. The date you file establishes your effective date.
2. Claim Development (30–60 days) — The VA gathers your service records and medical evidence. They may request additional information.
3. C&P Exam (60–90 days) — The exam is typically scheduled within this window.
4. Rating Decision (90–150 days) — A VA rater reviews all evidence and issues a rating decision.
5. Notification — You receive a decision letter with your disability rating and compensation amount.

If you disagree with the decision, you have one year to file an appeal.

Common Mistakes to Avoid

• Filing without a nexus letter. Without medical evidence linking your condition to service, the VA will likely deny your claim. Learn about nexus letters.
• Not claiming secondary conditions. Many veterans don’t realize that conditions caused by their service-connected disabilities are also compensable. Learn about secondary claims.
• Being vague on your claim form. Specifically describe each condition, its symptoms, and how it connects to your service.
• Missing deadlines. You generally have one year from a denial to appeal. Missing this deadline can mean losing back pay.
• Not attending the C&P exam. If you miss your exam without good cause, your claim will likely be denied.
• Not reviewing your C&P exam results. Request a copy of the examiner’s report (Disability Benefits Questionnaire). If it contains errors, you can submit a rebuttal.

Secondary Service Connection in Detail

Secondary service connection (38 CFR § 3.310) is one of the most underutilized paths to increased compensation. A secondary condition is one that is proximately due to or aggravated by a service-connected disability.

Common secondary connection examples:

• Knee/hip problems secondary to service-connected back injury (altered gait)
• Depression or anxiety secondary to chronic pain from service-connected conditions
• Sleep apnea secondary to PTSD or weight gain from limited mobility
• Peripheral neuropathy secondary to diabetes (if diabetes is service-connected)
• Erectile dysfunction secondary to medications for service-connected conditions
• GERD (acid reflux) secondary to medications or PTSD
• Radiculopathy secondary to service-connected spinal conditions

To establish secondary service connection, you need a nexus letter from a qualified medical provider stating that your secondary condition is “at least as likely as not” caused by or aggravated by your primary service-connected condition.
