VA Secondary Conditions Guide

Organize evidence for a claimed secondary condition while separating your observations from medical opinions.

VA Secondary Conditions Guide is a 4-page PDF field guide. Secondary service connection, evidence and medical-opinion boundaries.

• A current condition is required: Symptoms should be evaluated and documented by qualified medical professionals.

• The primary condition must be identified: The theory connects the new condition to an already service-connected disability.

• Causation and aggravation differ: A condition may be caused by or worsened beyond natural progression by another condition.

• Evidence must fit the theory: Treatment history, medical reasoning and lay observations serve different roles.

Action checklist: Name the diagnosed secondary condition; Identify the primary service-connected condition; Choose causation or aggravation theory; Collect relevant treatment records; Write a factual timeline; Seek accredited help for claim strategy.

Medical nexus and legal sufficiency are claim-specific; this guide does not provide a diagnosis or legal opinion.
