Secondary Conditions
Secondary claims: the fastest way to raise a VA rating
A secondary claim connects a new condition to an already service-connected one. You don't have to re-prove your in-service event — you just need a well-reasoned nexus letter.

FAQ
Frequently Asked Questions
What is a secondary condition claim?
A claim that links a new condition to one the VA has already service-connected. Once granted, the secondary condition is rated on its own and combines into your total rating.
Do I need a separate nexus letter?
Yes — the secondary condition needs its own medical opinion linking it to your service-connected condition.
How is secondary connection proven?
The nexus letter explains the medical mechanism (e.g., how PTSD hyperarousal fragments sleep and contributes to obstructive sleep apnea) and cites the peer-reviewed literature.
