Secondary service connection
A secondary is its own claim. Here's one, built.
Secondary service connection (38 CFR § 3.310) allows a veteran to receive compensation for a condition that was proximately caused by or aggravated beyond natural progression by a service-connected disability. A nexus letter from a qualified medical provider is required. This tool describes the medical framework — not the claim strategy. The app builds the claim itself.
- The diagnosis, read from your records — or what to add
- Your statement and a buddy's, in your own words
- The medical opinion linking the two, signed by a licensed clinician for eligible conditions
