As of 2015, Medicare Part B covers a three-month trial of Continuous Positive Airway Pressure therapy for those who are qualified, according to Medicare. In order for a patient to qualify, a diagnosis of obstructive sleep apnea is required and a doctor must prescribe the relevant durable medical equipment.
Medicare coverage of the durable medical equipment may extend beyond the initial three-month trial period if the doctor notes in the patient's medical record that the CPAP equipment is improving the patient's condition, notes Medicare. Additionally, Medicare may cover the replacement or rental of existing CPAP equipment for newly enrolled Medicare members.
Durable medical equipment is only covered by Medicare if the prescribing doctor and the equipment supplier are enrolled in Medicare, explains Medicare. Unenrolled suppliers and physicians are not bound by the amount they charge, and they may require the patient to pay for services and equipment upfront.
