What a Nexus Letter Actually Is

A nexus letter is a medical opinion stating that a condition is “at least as likely as not” related to military service.

It must be written by a qualified medical professional and supported by service records, medical evidence, and sound reasoning.

Key Elements of a Strong Nexus Letter
  • Clear medical credentials of the provider
  • Review of relevant service and medical records
  • Use of proper VA legal language
  • Clear explanation of medical reasoning
