What are Nexus Letters for Veterans ? | VA Disability

Physician Assistant and prior C&P examiner Leah Bucholz discusses What are Nexus Letters for Veterans?
Nexus letters are technical reports, also referred to as independent medical opinions, that establish a link between an injury or illness and a veteran's service. Such letters, usually drafted by medical professionals like doctors, nurse practitioners, or PAs, detail how one condition relates to another or to the veteran's service. The letters can range from a few sentences to lengthy reports, with an emphasis on presenting a rational connection. Leah differentiates between primary and secondary service connections, detailing examples for each. Primary connections have a direct relationship to one's service, while secondary connections relate a condition to another service-connected condition. She also highlights presumptive service connections that are assumed by the VA based on specific criteria. Leah emphasizes that while Nexus letters determine service-related connections, Disability Benefits Questionnaires (DBQs) help ascertain the rating.
