Free VA Secondary Conditions Finder

Find secondary VA disabilities backed by historical precedent. This 100% free interactive tool analyzes 1.88 million Board of Veterans' Appeals (BVA) cases and 4.1 million issue results (1992-2026). Combined with curated data, this map reveals the statistical links between your service-connected disabilities and possible secondary condition claims.

How To Read The Secondary Condition Map

  • Teal rings: Conditions secondary to your selected disability.
  • Purple rings: Conditions that cause your selected disability.
  • Dashed gray rings: Bidirectional conditions linked both ways.

Search Claims Evidence Instantly

  • Hover any condition to spotlight its specific connection lines.
  • Arrow direction points from the primary condition to the secondary claim.
  • Click to lock your view and display both connection lists.
  • Open the diagnostic code page for your nexus evidence.

Claiming through a chain? See Causation Chains and the intermediate-step rule → for how a condition is claimed secondary to a second condition that traces back to a service-connected one, with worked examples and the Board decisions that granted them.

Tip: type or click a condition to compare its two directions (what it causes vs. what causes it). Until then the map shows both directions.

These connections show conditions veterans claimed as secondary to one another in published BVA appeals (1992-2026). They are appeal-level outcomes only; many secondaries are granted at the initial claim without ever needing an appeal. Use them as an indication that two conditions may be related, not proof. A connection in some cases does not mean a connection in yours. To claim any condition you still need a current medical diagnosis, an in-service event, and a nexus that ties them together.
