Who this is for
Patients, caregivers, families planning discharge, bedside clinicians, and case managers.
60-second summary
Durable medical equipment, or DME, is reusable medical equipment needed at home. Medicare may cover medically necessary DME when rules are met. The equipment usually needs a provider order, medical necessity, home use, and a Medicare-enrolled supplier. Helpful equipment, convenience items, and home modifications are not automatically covered.
Fact sheet
Durable medical equipment
Reusable medical equipment used for a medical reason, usually at home, and expected to last over time.
- Examples may include walkers, wheelchairs, commodes, oxygen equipment, hospital beds, CPAP supplies, crutches, canes, and other medically necessary equipment.
- DME must generally be durable, medically necessary, useful because of illness or injury, used in the home, and expected to last.
- It is usually covered under Medicare Part B rules, not automatically covered because the patient was hospitalized.
- The exact item, supplier, documentation, and plan rules matter.
Provider order
The clinician’s order and documentation explaining why the equipment is medically necessary.
- A provider may need to document the diagnosis, functional limitation, home need, and expected duration.
- Higher-level equipment may require stronger documentation.
- Missing or weak documentation can delay approval or delivery.
- The order often needs to go to a supplier that meets Medicare or plan requirements.
Supplier rules
Coverage and cost can depend on whether the supplier participates with Medicare, accepts assignment, or is in-network with the plan.
- Original Medicare patients should ask whether the supplier accepts Medicare assignment.
- Medicare Advantage patients may need an in-network supplier and prior authorization.
- A non-participating supplier can create higher costs or upfront payment issues.
- Delivery timing can depend on supplier availability and insurance approval.
Rent vs. buy
Some equipment is purchased, some is rented, and some may become owned after a rental period.
- Oxygen, hospital beds, wheelchairs, and other equipment may have rental rules.
- Rental billing can continue over time.
- Repairs, replacement, accessories, and supplies may have separate rules.
- Patients should ask whether the item is rented, purchased, or capped rental.
DME vs. home modification
DME is medical equipment; home modifications are changes to the home environment.
- Examples of home modifications include ramps, grab bars, stair lifts, bathroom renovation, widened doorways, and long-term safety changes.
- These may be extremely helpful but are often not covered by Medicare as DME.
- Medicaid waivers, Veterans benefits, community programs, or private pay may apply in some cases.
- Families should separate equipment needed now from home changes needed for long-term safety.
Questions to ask before discharge
- What equipment is medically necessary for discharge?
- Has the provider written the order?
- Which supplier is being used?
- Does the supplier accept Medicare assignment or participate with the plan?
- Is prior authorization needed?
- Is the item rented or purchased?
- What will the patient owe?
- When will the equipment be delivered?
The walker is easy; the hospital bed is not
A patient needs a walker and a hospital bed before going home. The walker is straightforward, but the bed requires stronger documentation, supplier coordination, delivery timing, and cost-sharing review. The family should ask about orders, supplier assignment, rental billing, delivery, and backup plans before discharge day.
Common mistakes
- Assuming every helpful item is covered.
- Forgetting to ask whether the supplier accepts Medicare assignment.
- Not checking Medicare Advantage network or prior authorization rules.
- Assuming a hospital discharge automatically makes equipment free.
- Confusing DME with home modifications.
- Waiting until the day of discharge to solve equipment delivery.
Key takeaway
Medicare may cover medically necessary durable medical equipment for use at home, but coverage depends on orders, documentation, home-use rules, supplier rules, and cost-sharing. Ask early what is covered, what is not covered, when it will arrive, and what the patient may owe.
