VA Secondary Conditions Tools

Many veterans leave benefits on the table by not claiming conditions that are linked to one they are already rated for. These free tools help you explore likely secondary conditions, build the medical link, and organize the evidence to support each one.

Frequently asked questions

What is a VA secondary condition?
A secondary condition is a new condition caused or aggravated by a condition VA has already service-connected. You show it is linked to your existing rated condition rather than proving it started in service.
What evidence does a secondary claim need?
A current diagnosis of the secondary condition and a medical nexus linking it to your service-connected primary condition, on a causation or aggravation theory. A nexus letter is often the key piece.
