Free VA Secondary Conditions Finder

Find secondary VA disabilities backed by historical precedent. This 100% free interactive tool analyzes 1.9 million published Board of Veterans' Appeals decisions covering 1992 to 2026, and 4.1 million+ issue results inside them. 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.

A body-system filter shows every connection that involves that system. The condition on the other end of a connection often belongs to a different system, which is the point: secondary claims cross body systems constantly.

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.

Line color shows the grant rate in BVA decisions for that secondary claim (descriptive, not a prediction of your claim): 50% or more granted 30 to 49% granted Under 30% granted Fewer than 20 decisions, too few to state a grant rate. These are curated pairings, which stay on the map whatever the minimum is set to Dash-dot: aggravation is a live path here, a third or more of the Board's mechanism grants for this pair were "made worse by", not "caused by" (hover a line for the counts) When you focus a condition, its neighbors are ringed by direction: Secondary to it (the arrow points here) It is itself secondary to these Claimed both ways (bidirectional)

This map vs the graph on a condition page. The full finder compares both directions across every condition. A diagnostic-code page shows only what is claimed secondary to that one code. One page explains the difference.

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.
