Durable Medical Equipment (DME)

Medical equipment that is ordered by a doctor (or, if Medicare allows, a nurse practitioner, physician assistant or clinical nurse specialist) for use in the home. A hospital or nursing home that mostly provides skilled care can't qualify as a 'home' in this situation. These items must be reusable, such as walkers, wheelchairs, or hospital beds. DME is paid for under both Medicare Part B and Part A for home health services.
