The Equipment That Keeps You Independent
Durable medical equipment — DME for short — is the category of Medicare coverage that helps people stay mobile and independent: wheelchairs, walkers, canes, oxygen equipment, hospital beds, blood sugar monitors, and more. Medicare Part B covers medically necessary DME, but there are rules about doctor orders and approved suppliers that determine whether you'll actually be covered. Getting those rules right saves money and hassle.
For many older adults, the right equipment makes the difference between managing at home and not. Here's how Medicare's DME coverage works and how to get equipment covered smoothly.
What Counts as DME
Medicare defines DME as equipment that's durable (can withstand repeated use), used for a medical reason, generally not useful to someone who isn't sick or injured, and appropriate for use in the home. Common covered items include:
- Mobility aids: wheelchairs, power scooters, walkers, canes, and crutches
- Oxygen equipment and supplies
- Hospital beds and pressure-reducing mattresses
- Blood sugar monitors, test strips, and continuous glucose monitors (see [Medicare and diabetes](/blog/medicare-diabetes-coverage-2026))
- Nebulizers, CPAP machines, and related supplies
- Patient lifts and commode chairs
The Rules That Determine Coverage
Two rules matter most. First, your doctor must order the equipment and document that it's medically necessary for use in your home — DME isn't something you can just buy and expect Medicare to reimburse. Second, you generally must get the equipment from a supplier enrolled in Medicare, and ideally one that 'accepts assignment,' meaning they agree to Medicare's approved amount. Using a non-participating supplier can leave you paying much more.
You typically pay 20% coinsurance after your Part B deductible for covered DME, and a Medicare Supplement covers that coinsurance. Some equipment is rented rather than purchased, and expensive items like oxygen often follow a rental arrangement. On a Medicare Advantage plan, DME is covered with the plan's cost-sharing and may require prior authorization and use of specific suppliers.
Getting Your Equipment Covered Without Surprises
To avoid problems: make sure your doctor documents the medical need and writes the order, use a Medicare-enrolled supplier that accepts assignment, and confirm coverage before taking the equipment — especially for pricier items. If you're on a Medicare Advantage plan, check whether prior authorization is needed and which suppliers are in-network. A little confirmation up front prevents a surprise bill or a denied claim.
DME coverage rules — and which suppliers accept assignment — can be confusing, and getting it wrong is expensive. We help clients understand what's covered and navigate the supplier requirements, at no cost. If you or a family member needs equipment to stay safe and independent at home, making sure Medicare covers it properly is exactly the kind of practical help we provide.
Frequently Asked Questions
Does Medicare cover wheelchairs and walkers?
Yes. Medicare Part B covers medically necessary durable medical equipment including wheelchairs, walkers, canes, and power scooters, when your doctor orders them for home use. You pay 20% coinsurance after the Part B deductible.
Does Medicare cover oxygen and CPAP machines?
Yes, when medically necessary and ordered by your doctor. Oxygen equipment is typically covered as a rental, and CPAP machines are covered for diagnosed sleep apnea, often with an initial trial period. Standard Part B cost-sharing applies.
Where do I have to buy Medicare-covered equipment?
From a Medicare-enrolled supplier, ideally one that 'accepts assignment' (agrees to Medicare's approved amount). Using a non-participating supplier can leave you paying significantly more. Medicare Advantage plans may require specific in-network suppliers.
Does Medicare Advantage cover durable medical equipment?
Yes, but with the plan's own cost-sharing, and it may require prior authorization and use of specific suppliers. Confirm the requirements before obtaining equipment to avoid denied claims or surprise costs.
