How to Ask Your Doctor for a Nexus Letter
Before you ask
- Gather your (STRs), separation exam, and post-service treatment records for the condition.
- Identify the specific in-service event, injury, illness, or exposure you are linking the current condition to.
- Confirm the current diagnosis is in the provider's chart or is documented elsewhere you can share.
A framework for the request
- Ask in writing. A short letter or portal message is easier for the provider than a rushed appointment ask.
- Explain what VA needs: a written opinion, based on the provider's review of your records, on whether your current [condition] is '' related to a specific in-service event or exposure.
- Explain the standard in plain terms: '' means a 50 percent or greater probability. VA gives little weight to opinions phrased as 'possibly' or 'could be.'
- Offer the records the provider will need to review, or ask what they would like you to bring.
- Ask the provider to include the — the medical reasoning that supports the opinion.
- Be clear the opinion should reflect their honest professional judgment. A letter written to a predetermined conclusion is not what VA wants and is not what will help.
If the provider declines
Some hospital systems (including some VA facilities) restrict clinicians from writing disability opinions. Some providers decline because they have not treated you long enough, or because the causal question is outside their comfort. That is a legitimate professional choice, not a comment on your .
Options if declined: ask another treating provider, seek an () from a specialist familiar with VA opinions, or rely on the C&P examiner's opinion at your next exam.
What not to do
- Do not write a draft letter for the provider to sign. VA generally rejects opinions that appear to be authored by the claimant.
- Do not pressure a provider who has expressed hesitation.
- Do not misrepresent the records you provide.
