Sleep Apnea and VA Disability: Complete Guide Series
A complete set of plain-English guides on sleep apnea and VA disability: service connection, ratings under Diagnostic Code 6847, and secondary connection to PTSD.
Overview
Start here: sleep apnea basics.
Sleep apnea is one of the most commonly claimed conditions in the VA system, and it raises several separate questions: whether the condition can be connected to service, how the VA rates its severity, and whether it can be connected secondary to another service-connected condition.
