Requires use of breathing assistance device (CPAP, BiPAP, APAP). This is the most common rating — once you have a CPAP, you typically get at least 50%.
Sleep study (polysomnogram or home sleep test) showing AHI (apnea-hypopnea index) ≥ 5 events/hour
CPAP/BiPAP prescription + use records (compliance reports from device download — typically 4+ hours/night for 70%+ of nights)
In-service sleep disturbance documentation (if claiming direct service-connection) OR diagnosis after service (if claiming secondary to PTSD/burn-pit/weight gain)
Nexus letter linking sleep apnea to in-service event/condition (often filed as secondary to PTSD, TBI, or PACT-Act respiratory presumptives)
Common filing mistakes
Not filing as secondary to a service-connected condition — sleep apnea secondary to PTSD/TBI/burn-pit is much more commonly granted than direct service-connection
Claiming 100% based on CPAP alone — CPAP only triggers 50%, not 100%
Failing to claim secondary conditions like erectile dysfunction (often secondary to OSA) which can add a SMC-K award
