Durable medical equipment (DME), also known as DMEPOS (Durable Medical Equipment, Prosthetics, Orthotics, and Supplies) is equipment that primarily serves a medical purpose, is able to withstand repeated use, and is appropriate for use in the home; for example, wheelchairs, oxygen equipment, and hospital beds. To be covered by Medicare, durable medical equipment must be prescribed by a doctor. Many types of adaptive equipment are not covered.
