Medicare Part B covers CPAP equipment when you meet these requirements: 1) A face-to-face evaluation with your doctor documenting sleep apnea symptoms. 2) A qualifying sleep study (in-lab or home test) showing an AHI of 5 or higher. 3) A prescription from your treating physician. 4) Initial 90-day trial period to demonstrate CPAP usage of at least 4 hours per night on 70% of nights. After meeting compliance requirements, Medicare covers 80% of the approved amount for CPAP rental and supplies. You pay 20% plus any unmet Part B deductible.
