What Makes a Strong Nexus Letter

Why we don't publish sample nexus letters

There is no shortage of sample nexus letters online, and most of them do more harm than good. When a letter reads like a template, VA discounts it — the reviewer has seen the same paragraphs many times. Copying language your provider did not write also creates ethical and evidentiary problems and can invite skepticism about the entire opinion.

What we can do is describe the elements VA weighs. A qualified provider — writing in their own voice about the specific facts of your record — is far more persuasive than any template.

The five elements VA weighs (per Nieves-Rodriguez v. Peake, 22 Vet. App. 295)

1. Qualifications — is the provider trained and licensed to opine on this condition? A pulmonologist opining on sleep apnea; a psychiatrist on PTSD; an audiologist on hearing loss.
2. Record review — did the provider actually review the service treatment records, post-service records, and any prior C&P opinion? The letter should reference specific records by date or event.
3. Correct legal standard — does the opinion use 'at least as likely as not' (or stronger)? Weaker phrasing generally fails.
4. Rationale — does the letter explain why? Accepted medical principles plus the specific facts of this veteran's case. A bare conclusion is worth little.
5. Acknowledgment of contrary evidence — if the record includes evidence pointing the other way (e.g., a normal separation exam, a prior denial, intercurrent injuries), the opinion is strongest when it addresses that evidence and explains the different conclusion.

Structural elements a strong letter usually includes

• The provider's credentials, license, and relevant training.
• The date and scope of the record review.
• The veteran's relevant service history and current diagnosis.
• The identified in-service event, injury, illness, or exposure.
• The medical reasoning connecting the two, with citations to accepted medical principles where relevant.
• The nexus statement using the correct standard.
• Signature, credentials, and date.

Red flags in weak letters

• One or two sentences and no rationale.
• 'Possibly related,' 'could be caused by,' 'cannot be ruled out.'
• No reference to any specific record the provider reviewed.
• Boilerplate paragraphs that appear in many other letters.
• Opinions from providers outside their scope of practice for the condition at issue.
