GERD, IBS, Diabetes, and Thyroid VA Claims: Complete Guide Series
Plain-English guides to digestive and internal medicine VA disability claims: GERD under Diagnostic Code 7206, IBS under 7319, diabetes under 7913, thyroid conditions, and secondary claims.
Overview
Start here: digestive & internal medicine basics.
Digestive and endocrine conditions are among the most commonly diagnosed disabilities in the veteran population, and they raise several separate questions: whether a condition can be connected to service years later, how the VA measures severity under criteria that changed in 2024, and when reflux, bowel disease, or metabolic conditions can be connected secondary to an already service-connected disability.
The guides below work through each question using the VA's own regulations. Start with the overview, then read the guide that matches your situation.
