Durable medical equipment

Also: DME · medical equipment

Reusable medical equipment for long-term use at home: wheelchairs, walkers, hospital beds, oxygen concentrators, CPAP machines, glucose meters, lift chairs, etc. Medicare Part B covers 80% of approved DME for eligible patients with a prescription; the remaining 20% comes out of pocket or via Medigap.

What it means in practice

DME is the reusable equipment a patient uses at home for medical reasons. Medicare's standard is "withstands repeated use, primarily and customarily used to serve a medical purpose, generally not useful in the absence of illness or injury, appropriate for use in the home." That defines what qualifies (e.g., a wheelchair) vs. what doesn't (e.g., a regular bed, since beds are useful for non-medical purposes).

Medicare Part B coverage for DME requires three things: (1) a physician's prescription, (2) the supplier must be Medicare-enrolled (and for many items, must meet competitive-bidding contract requirements in the patient's ZIP code), and (3) the equipment must meet medical-necessity criteria spelled out in CMS Local Coverage Determinations. Some items have strict documentation requirements that the prescribing doctor's office handles; others rent first (with monthly Medicare payments) then convert to ownership after a "capped rental" period.

Common DME categories families encounter:

• **Mobility**: standard walker (often $50-100, fully covered with $20-40 patient share), rollator with seat, manual wheelchair, power wheelchair, scooter, lift chair (for the lift mechanism — the chair itself isn't covered) • **Bed equipment**: hospital bed, trapeze, alternating-pressure mattress (for wound prevention), bedside commode • **Respiratory**: home oxygen (concentrator + tanks), CPAP/BiPAP, nebulizer • **Diabetes**: glucose meter, test strips, continuous glucose monitor (CGM — increasingly covered), insulin pump • **Daily living**: shower chair, raised toilet seat, grab bars (these are typically NOT covered — Medicare considers them "convenience items"; families pay out-of-pocket)

The 20% patient coinsurance has no annual cap on original Medicare (Medigap covers it; Medicare Advantage has its OOP max).

What's often NOT covered: home modifications (ramps, doorway widening), most personal-care items (incontinence supplies, except in specific cases), most home-safety items (grab bars, non-slip mats). Some Medicare Advantage plans add benefits for these as supplemental coverage; check your parent's specific plan.

When you'll hear it

After hospital discharge when home equipment is being arranged ("the hospital is sending over a walker through DME"). Also during the management of any chronic condition that needs supportive equipment.

Is this the same as…?

Terms families frequently confuse with durable medical equipment.

Is durable medical equipment the same as home health?

Home health is the SERVICE — nurses, therapists, aides coming to the home. DME is the EQUIPMENT delivered to the home. Both are Medicare-covered under specific conditions but they're different benefit structures with different eligibility rules.
