Durable medical equipment is that your doctor prescribes for use in your home. Only your doctor can prescribe medical equipment for you.
Durable Medical Equipment (DME) is equipment which can stand repeated use, is used to serve a medical purpose and is appropriate for use within the home. DME is generally not useful to a person in the absence of illness or injury.
Durable medical equipment is called durable because it's designed to be operated on a regular basis by a non-medical professional. Durable medical equipment might be used daily, hourly or potentially all day long. This type of medical equipment needs to be easy to use and not surprisingly -- durable.
