Durable Medical Equipment is known as any medical equipment used in the home to aid in a better quality of living.

Durable Medical Equipment (DME) is any equipment that provides therapeutic benefits to a patient in need because of certain medical conditions and/or illnesses. DME can typically be defined as products that meet the following criteria: Primarily and customarily used to serve a medical purpose, are not useful to a person in the absence of illness or injury, are ordered and prescribed by a physician, are reusable, can stand repeated use and are appropriate for use in the home. 

Insurances use this definition as a qualification for coverage.  If the product meets the above criteria, then typically it would be covered by most insurances, although every individual should check with their insurance to be sure the product is covered.
