A medical assistant is obtaining prior authorization from Medicare for a piece of durable medical equipment that treats obstructive sleep apnea. Which of the following should the assistant request?

A nebulizer is used to deliver medication in the form of mist to the lungs, primarily for conditions such as asthma or chronic obstructive pulmonary disease (COPD). While it is an essential device for respiratory illnesses, it does not specifically treat obstructive sleep apnea, making it inappropriate for this case.

A suction pump is generally utilized to remove secretions from a patient’s airway or other body cavities, often in emergency or surgical settings. It is not used for treating obstructive sleep apnea and does not provide any benefit for this condition, thus making it an unsuitable choice for authorization.

Pressure-reducing support surfaces, such as specialized mattresses or cushions, are designed to prevent pressure ulcers in immobile patients. Although they serve an essential purpose in patient care, they do not address the treatment of obstructive sleep apnea and are therefore irrelevant to this request.
