Nexus Letters

What Is a Nexus Letter?

A Nexus Letter is a medical opinion from a licensed physician that connects your current disability to your military service. It's often the missing piece that makes or breaks a VA claim.

Medical Expert Opinion

A physician reviews your records and provides a professional medical opinion on the connection between your condition and service.

Evidence-Based

Backed by medical research, case law precedent, and thorough review of your service and medical history.

Strengthens Your Claim

Provides the medical nexus (connection) that helps the VA understand why your condition was caused by service.
