Filing for VA disability benefits can feel like decoding a complex manual made of acronyms and legal jargon. Whether you’re applying for the first time, requesting an upgrade, or appealing a decision, mastering these 20 key terms can give you a significant advantage—and help steer clear of common mistakes. These definitions are simplified so you can confidently navigate the claims process.
🧩 Foundations: Service Connection & Supporting Evidence
- Service Connection
To receive VA disability compensation, you must prove your condition is linked to your military service—through a current diagnosis, evidence of an in-service event or injury, and documentation that connects the two. - Nexus
Also known as the medical connection, a nexus is proof (often via a medical opinion) that ties your current disability to your service. A clear nexus is crucial—without it, your claim may be denied. - Lay Evidence
These are personal statements—yours or from others—describing your symptoms or how your condition affects your life when medical records fall short. - Buddy Letter
A type of lay evidence from someone who witnessed your condition—like a fellow service member, spouse, or friend—that offers insight into your experience and supports your claim. - Service Treatment Records (STRs)
These are your official military medical records that show treatment received during service. They help establish your condition’s origin and severity.
📝 Forms, Exams & Documentation
- C&P Exam (Compensation & Pension Exam)
A medical exam arranged by the VA to confirm your diagnosis, assess how it affects you, and determine its link to service. The exam results strongly influence your claim outcome. - DBQ (Disability Benefits Questionnaire)
A standardized form used by examiners to record findings from your C&P exam. A well-completed DBQ can significantly strengthen your claim. - VA Form 21-526EZ
This is your main application for VA disability compensation. You can submit it online, by mail, or in person. - VA Form 20-0995 (Supplemental Claim Request)
Used if the VA has already made a decision (after Feb 19, 2019), and you want them to review it again based on new, relevant evidence. - VA Form 21-4138 (Statement in Support of Claim)
A general-purpose form you can use to provide additional details—like describing your symptoms or providing a personal account.
🔍 Understanding Conditions & How Impairment Is Evaluated
- Presumptive Condition
Certain diseases (such as those linked to Agent Orange or burn pits) are automatically presumed to be service-related under specific conditions—meaning you don’t need to provide a detailed nexus. - Chronic Condition
A long-term or frequently recurring condition that can support your claim even if you lack STRs—as long as you can show it began during service. - Aggravation
This term applies when a service-related condition gets worse due to service. You can receive disability benefits for the increased severity. - Secondary Service Connection
When a service-connected condition leads to another disability (for example, knee arthritis caused by a limp), that new condition may also be eligible for compensation. - Functional Impairment
This measures how much your condition interferes with daily living and work. The VA uses this to determine disability ratings.
🏅 Ratings, Compensation & Appeal Terms
- Combined VA Rating
The VA uses a specific formula to combine multiple disability percentages into a single overall rating—rounded down to the nearest 10%. - SMC (Special Monthly Compensation)
Extra tax-free compensation beyond your regular rating if you’re severely disabled—such as loss of limbs, sight, or other specific needs. - TDIU (Total Disability Individual Unemployability)
If your service-connected disability prevents you from working, the VA may grant you 100% compensation even if your combined rating is below 100%. - VA Effective Date
This is the date that determines when your benefits begin. It’s usually the date the VA receives your claim or your “intent to file.” - Appeals Modernization Act (AMA)
Enacted in 2019, AMA is the current VA appeals system. It replaced the old appeals process and includes options like supplemental claims and higher-level reviews. vaclaimsinsider.com
