Nexus Letter
A written medical opinion from a qualified healthcare provider that establishes a link ('nexus') between a veteran's current medical condition and their military service, used to support a VA disability claim.
The nexus letter must use the 'at least as likely as not' standard (≥50% probability) to be persuasive. Independent nexus letters from private doctors can overcome a VA examiner's negative C&P opinion.
→ A strong nexus letter is one of the most powerful pieces of evidence in a VA disability claim.
