Durable medical equipment (DME) is equipment that is ordered by a doctor (or, if Medicare allows, a nurse practitioner, physician assistant or clinical nurse specialist) for use in the home. A hospital or nursing home that mostly provides skilled care can’t qualify as a ‘home’ in this situation.

Durable medical equipment includes (but is not limited to) air-fluidized beds and other support surfaces, blood sugar monitors and test strips, commode chairs, continuous passive motion machine, hospital beds, infusion pumps and supplies, nebulizers and nebulizer medications, oxygen equipment and accessories, patient lifts, sleep apnea and CPAP devices and accessories, suction pumps, and traction equipment.

Movement devices (which fall under DME) can include canes, crutches, manual wheelchairs and power mobility devices, and walkers.
