what is a nexus letter

A nexus letter is a document prepared by a physician or other medical professional that explains how a veterans medical illness or condition is directly related to their military service. It is a crucial piece of evidence in a veterans disability benefits claim, as it establishes the connection between the current medical condition and the in-service event that caused it. The letter must be written specifically for the individual and be explicit to that individuals claim. It should be detailed, complete, and written by a medical expert who has thoroughly reviewed all available and pertinent medical records. The nexus letter is especially crucial if no medical records were provided in support of the application and the C&P examiner does not find a link between the veteran’s illness or disability and their military service. It can make the difference between an application being approved or denied. The letter should include specific language, certain phrases, and the correct medical standard to strongly support the claim. It is best to choose a doctor who is currently treating the veteran and is board-certified in the area of health that is at issue in the case to write the nexus letter on their behalf.
