A durable medical equipment business is a company that sells health care related items intended for use in the home for an extended period. Products such as wheelchairs, hospital beds, glucose monitors and nebulizers are considered durable medical equipment, and are often covered by insurance plans and Medicare provided that the equipment is intended for long-term use.
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. Medical supplies of an expendable nature, such as bandages, rubber gloves and irrigating kits are not considered by Medicare to be DME.ome equipment, such as oxygen, is FDA regulated and must be prescribed by a physician before purchase whether insurance reimbursed or otherwise. The physician may recommend a supplier for the home medical equipment, or the patient will have to research this on their own.
