This article discusses the definitions and types of home medical equipment (HME), also known as durable medical equipment (DME), and durable medical equipment prosthetics and orthotics (DMEPOS). HME / DMEPOS Home medical equipment is a category of devices used for patients whose care is being managed from a home or other private facility managed by a nonprofessional caregiver or family member. It is often referred to as "durable" medical equipment (DME) as it is intended to withstand repeated use by non-professionals or the patient, and is appropriate for use in the home.

The physician may recommend a supplier for the home medical equipment, or the patient will have to research this on their own. HME / DMEPOS suppliers are located throughout the country and some specialty shops can also be found on the internet. There is no established typical size for HME / DMEPOS suppliers. Supply companies include very large organizations such as Walgreens, Lincare, and Apria to smaller local companies operated by sole proprietors or families. A new evolution in the home medical equipment arena is the advent of internet retailers who have lower operating costs so they often sell equipment for lower prices than local "brick and mortar", but lack the ability to offer in-home setup, equipment training and customer service.
