HOW ELLIS CLINIC HELPS VETERANS

The Medical Evidence Behind a VA Disability Claim

A diagnosis by itself does not always answer the VA's medical question. The important issue may be whether a condition began in service, was caused or aggravated by another service-connected condition, or is supported by enough medical evidence to justify a Nexus opinion.

Nexus Opinions

Medical evaluation of whether the available evidence supports a connection between a current condition and military service or an already service-connected disability.

THE ELLIS APPROACH TO NEXUS

A Strong Opinion Explains the Connection.

A useful Nexus opinion should do more than state that two conditions are related. It should explain the chronology, objective evidence, medical mechanism, relevant records, and alternative explanations so the reasoning can be followed.

Ellis Clinic's approach is evidence-first: the desired result does not determine the medical conclusion. The records and medical reasoning do.

01CHRONOLOGYWhen did symptoms, diagnoses, injuries, exposures, and treatment occur?
02OBJECTIVE EVIDENCEWhat do examinations, tests, imaging, sleep studies, labs, and specialist records show?
03MEDICAL MECHANISMIs there a medically plausible pathway connecting the claimed conditions or events?
04ALTERNATIVESWhat competing explanations exist, and why are they more or less medically probable?
