Nexus Letter Request
Hand It to Your Own Doctor
A nexus letter is one of the most powerful pieces of evidence in a VA claim — but many veterans don't know how to ask their doctor for one. This free tool drafts a professional one-page request you can print and bring to your provider, with a plain checklist of exactly what the VA looks for.
What is a nexus letter — and why does it matter?
A nexus letter is a signed statement from a qualified medical provider giving their professional opinion on whether your current diagnosed condition is connected to your military service (a direct claim) or to another condition the VA has already service-connected (a secondaryclaim). It is the bridge between your diagnosis and your service — the “nexus.”
The VA evaluates that opinion against a specific legal standard: “at least as likely as not.” That means a 50% or greater probability — not absolute certainty. A clear opinion that uses this language, explains the medical reasoning behind it, and is signed by a qualified provider carries real weight with a rater.
This tool does not write the medical opinion — that has to come from a licensed provider exercising their own independent judgment. What it does is help you make a clear, respectful ask, and hand your provider a checklist so they know exactly what the VA needs to see. Many doctors are willing to help but simply don't know the format the VA expects.

No provider who'll write one?
If your own doctor won't write a nexus letter, a licensed provider through Commander Health can review your records and, where the evidence supports it, write and sign one for you — at a fraction of what others charge.
