Types of VA Disability Claims

VA disability claims come in many forms, from PTSD and TBI to toxic exposure and unemployability. This hub explains the main condition areas our Network Providers evaluate, the different ways a disability can be service-connected, and how the VA turns individual ratings into a single combined percentage. Use it as a map to the more detailed pages across our site.

An Overview of VA Disability Claims

The VA disability system compensates veterans for injuries and illnesses connected to their military service. In practice, that covers an enormous range of conditions, physical, mental, and those tied to toxic exposure. Two claims are rarely identical, because each depends on your service history, your diagnoses, and the medical evidence linking them.

This page groups our work into the condition areas veterans ask about most and links to a dedicated page for each. Whether you are filing for the first time, seeking a higher rating, or appealing a denial, start with the area that fits your situation and follow the links for detail.

General information, not legal advice. The summaries below explain how these claims generally work. Your outcome depends on your specific facts and evidence.

How Service Connection Works

Every disability claim rests on service connection, the link between your condition and your military service. There are four main ways to establish it:

  • Direct service connection — the condition began during or was caused by your service. This requires a current diagnosis, an in-service event or injury, and a medical nexus tying the two together.
  • Secondary service connection — a service-connected condition caused or aggravated a second condition. For example, service-connected knee damage that leads to a back problem, or a physical disability that contributes to depression.
  • Presumptive service connection — for certain conditions and service, the VA presumes the link without a nexus opinion. This covers many Agent Orange, Gulf War, and burn pit claims.
  • Aggravation — a condition that existed before service, or a nonservice-connected condition, was made permanently worse by service or by a service-connected disability. The VA compensates the increase in severity.

Choosing the right theory, or pursuing more than one, is often the key to a successful claim.

How Ratings and Combined Ratings Work

Once a condition is service-connected, the VA assigns a disability rating in 10% increments based on how severely the condition affects you. Each condition is rated under a schedule that describes the symptoms at each level.

When you have more than one rated condition, the VA does not simply add the percentages. It uses VA math, sometimes called combined ratings, which accounts for the fact that each disability applies to the portion of you that remains. Two 50% conditions do not equal 100%; they combine to 75%, which then rounds to the nearest 10%. This is why understanding the combined-ratings table matters, especially near thresholds like 70% (often relevant for TDIU) or 100%.

To estimate your combined rating and monthly payment, use our VA disability calculator and our back pay calculator, and review the current rates.

General information, not legal advice. Rating criteria are detailed and condition-specific. A calculator gives an estimate, not a guarantee of how the VA will rate you.

Frequently Asked Questions

What are the main ways a condition gets service-connected?
There are four: direct (the condition started in or was caused by service), secondary (a service-connected condition caused or worsened another), presumptive (the VA presumes the link for certain conditions and service), and aggravation (service permanently worsened a pre-existing condition). Many claims use more than one theory.
Why don't my ratings just add up to 100%?
The VA uses combined-ratings math rather than simple addition. Each disability is applied to the part of you not already accounted for, so two 50% ratings combine to 75%, not 100%. Our VA disability calculator estimates the combined result.
Which page should I start with?
Start with the condition that affects you most, using the linked list above. If you cannot work because of your conditions, review TDIU. If you were denied, start with our denied-claim and appeals pages.
Can I claim more than one condition at a time?
Yes. Most veterans have several service-connected conditions, and the VA rates each and then combines them. Filing related conditions together, including secondary conditions, often produces a more accurate overall rating.
Do you handle appeals as well as new claims?
Yes. We assist with initial claims, requests for higher ratings, and every appeal lane, including higher-level review, supplemental claims, the Board of Veterans' Appeals, and the Court of Appeals for Veterans Claims.
