If your doctor prescribes a walker, wheelchair, hospital bed, or oxygen equipment, Medicare’s durable medical equipment (DME) benefit is what pays for most of it — but the process of actually getting that equipment covered has more moving parts than people expect. Understanding how it works ahead of time can save you a frustrating back-and-forth when you actually need the equipment.
What Qualifies as Durable Medical Equipment
Medicare defines DME fairly specifically: equipment that’s durable (can withstand repeated use), used for a medical reason, not usually useful to someone without an illness or injury, appropriate for use in the home, and expected to last at least three years. Common examples include walkers, wheelchairs, hospital beds, oxygen equipment, CPAP machines, blood sugar monitors, and patient lifts. Items that don’t meet all of these criteria — even if they’re medically helpful — may not qualify as DME, which is a common source of confusion.
Part B Covers DME, With Cost-Sharing
Durable medical equipment is covered under Medicare Part B, not Part A, which means it’s subject to the Part B deductible ($283 for 2026) and standard 20% coinsurance after that deductible is met. This is different from how people sometimes assume equipment is covered — it’s treated similarly to a doctor visit or outpatient service, not bundled into a hospital stay, even if the need for the equipment arose during one.
You Need a Prescription and Documentation
Medicare requires a written order from your doctor, along with documentation supporting medical necessity, before DME will be covered. For some categories of equipment, Medicare also requires prior authorization before the supplier delivers the item. Skipping this step — for example, ordering equipment through a supplier without first getting a proper prescription and documentation from your doctor — is one of the most common reasons DME claims get denied.
Suppliers Must Be Medicare-Enrolled
Not every equipment supplier is enrolled in Medicare, and buying from a non-enrolled supplier means Medicare won’t pay its share, even if the equipment itself would otherwise qualify. Before ordering DME, confirm the supplier is Medicare-enrolled and, if you’re on a Medicare Advantage plan, confirm they’re in your plan’s network as well. This is an easy detail to overlook when a supplier is recommended informally rather than through your doctor’s office.
Rental vs. Purchase
For some equipment, Medicare pays through a rental arrangement rather than an outright purchase, particularly for items like oxygen equipment or hospital beds. Depending on the equipment and how long you need it, ownership can sometimes transfer to you after a set rental period. It’s worth asking your supplier directly whether a specific item is being provided as a rental or a purchase, since this affects your long-term costs and what happens if your medical needs change and you no longer need the equipment.
Medicare Advantage Rules Can Differ
If you’re enrolled in a Medicare Advantage plan, your DME coverage generally mirrors Original Medicare’s baseline requirements, but the plan may have its own preferred supplier network, prior authorization process, or specific documentation requirements. Always check with your specific plan before assuming Original Medicare’s process applies exactly the same way.
A Practical Checklist Before Ordering DME
- Confirm your doctor has written a proper order and documented medical necessity.
- Check whether prior authorization is required for the specific equipment.
- Verify the supplier is Medicare-enrolled, and in-network if you’re on a Medicare Advantage plan.
- Ask whether the item is being provided as a rental or purchase, and what that means long-term.
- Budget for the Part B deductible and 20% coinsurance if you haven’t already met your deductible for the year.

Bottom Line
Durable medical equipment coverage under Medicare is solid, but it comes with real process requirements — proper documentation, enrolled suppliers, and sometimes prior authorization — that determine whether a claim gets approved smoothly or denied. Knowing the process before you need the equipment makes a real difference.
