Evidence-based Causal Letter
For veterans with both diagnoses documented. The letter presents a clear, evidence-backed causal opinion, supported by legal precedent, and written from a behavioral science perspective. It can be submitted in a claim in place of a medical nexus, though an Independent Medical Opinion is still advised.
Nexus Letter Toolkit
A clear framework for private medical providers. The template explains secondary service connection under 38 CFR, outlines M21-1 standards of proof, and applies the reasonable doubt rule. It guides providers to connect diagnoses, symptoms, and opinion in language the VA recognizes.
DBQ Support
A streamlined template for the VA's Disability Benefits Questionnaire. Providers can enter diagnoses, document symptoms, and state an opinion in clear language the VA accepts, making the process more efficient and reliable.
