Does Medicare Cover Durable Medical Equipment? The Supplier Rule Nobody Explains
The 80/20 split gets all the attention. The choice that actually determines your final bill is which supplier you use — and it works in two separate steps, not one.
Medicare Part B covers durable medical equipment (DME) — wheelchairs, walkers, hospital beds, CPAP machines, oxygen equipment, and similar items — when a doctor prescribes it as medically necessary for home use. After the annual Part B deductible ($283 in 2026), Medicare pays 80% of the approved amount and you pay the remaining 20%. But that clean 80/20 split only holds up if your supplier is actually enrolled in Medicare in the first place, and whether the 20% is capped or not depends on a second, separate choice your supplier makes.
Most explanations of Medicare DME coverage stop at "Medicare pays 80%, you pay 20%." That's true, but it skips the part that actually determines whether a wheelchair or CPAP machine costs a predictable coinsurance amount or turns into an open-ended bill. There are two separate supplier questions that matter, and they're not the same question.
What actually counts as DME
Medicare uses four tests to decide whether something qualifies as durable medical equipment: it has to be able to withstand repeated use rather than being disposable, it has to be primarily medical rather than something generally useful to anyone, it has to be appropriate for use in the home, and it has to be prescribed by a doctor as medically necessary for a specific condition. Common covered items include wheelchairs and power scooters, walkers and canes, hospital beds, CPAP and oxygen equipment, and blood glucose monitors and test strips. What's generally excluded: home modifications like ramps or grab bars, most disposable supplies, and equipment that's more convenience than medical necessity.
The cost-sharing math
Once an item qualifies, Medicare Part B pays 80% of the Medicare-approved amount, after the annual Part B deductible is met ($283 in 2026, the same deductible that applies across Part B services generally). You're responsible for the remaining 20% coinsurance. For an expensive item like a power wheelchair, that 20% is still a real number worth planning for, even though it's a meaningfully better deal than paying full retail.
Rent or buy? Depends on the item
Medicare doesn't treat every piece of equipment the same way when it comes to how you actually acquire it. Inexpensive or routinely purchased items, generally those around $150 or less, like a standard cane or walker, are typically bought outright. More expensive equipment that falls into Medicare's "capped rental" category, most notably power wheelchairs and scooters, is usually paid for through a monthly rental fee rather than a lump-sum purchase. For capped-rental items, Medicare-paid rental generally transfers ownership of the equipment to you after about 13 continuous months of rental payments, at which point the monthly payments stop and the item is yours.
The 80/20 Split
Medicare pays 80% of the approved amount after the $283 (2026) Part B deductible. You pay the 20% coinsurance.
Not Enrolled = $0 Paid
If your supplier isn't enrolled in Medicare at all, Medicare pays nothing — not a partial payment, a full $0.
Assignment = Capped 20%
A participating supplier accepts assignment on every claim, capping your cost at the standard coinsurance.
Non-Assigned = Uncapped
A non-participating supplier can decline assignment claim by claim, billing above the Medicare-approved amount.
The supplier rule that actually determines your bill
This is the part most explanations skip, and it's really two separate gates, not one. The first gate: is the supplier enrolled in Medicare at all? This isn't optional or a matter of degree. If a supplier isn't enrolled in Medicare as a DME supplier, Medicare pays $0, no matter how medically necessary the equipment is or how clearly a doctor prescribed it. There's no partial payment or balance-billing situation here, because there's no Medicare payment to begin with — the entire cost falls on the beneficiary. Checking that a supplier is Medicare-enrolled before ordering anything is a genuinely load-bearing step, not a formality.
The second gate only matters once you've cleared the first one: does the enrolled supplier accept Medicare assignment? A participating supplier agrees, as a condition of participating at all, to always accept assignment on every claim, meaning they accept the Medicare-approved amount as payment in full and can only collect your deductible and the standard 20% coinsurance from you. A non-participating supplier is still Medicare-enrolled, so Medicare will pay its 80% share, but that supplier can choose, claim by claim, whether to accept assignment. When they decline it, they're allowed to bill you more than the Medicare-approved amount, on top of the usual coinsurance, similar in spirit to how a doctor who doesn't accept assignment can bill a Part B excess charge under Original Medicare. Asking a supplier directly whether they're a participating Medicare supplier who accepts assignment, before agreeing to any equipment order, is the single question that determines whether your bill stays predictable or doesn't.
Frequently Asked Questions
What qualifies as durable medical equipment under Medicare?
Equipment that meets four tests: it can withstand repeated use, is primarily medical rather than of general use, is appropriate for use in the home, and is prescribed as medically necessary by a doctor. Common examples include wheelchairs, walkers, hospital beds, CPAP machines, oxygen equipment, and blood glucose monitors. Home modifications and most disposable supplies don't qualify.
How much does Medicare pay for DME?
Medicare Part B pays 80% of the Medicare-approved amount after you meet the annual Part B deductible ($283 in 2026), leaving you responsible for the remaining 20% coinsurance. That 20% is capped at the Medicare-approved amount only if your supplier accepts assignment — otherwise a non-participating supplier can bill more.
Does Medicare rent or buy equipment like wheelchairs?
It depends on the item. Inexpensive or routinely purchased items, generally $150 or less, like canes and walkers, are typically bought outright. More expensive capped-rental items, like power wheelchairs and scooters, are usually rented on a monthly basis, and Medicare-paid rental typically transfers ownership to you after about 13 months of continuous rental.
What happens if my DME supplier isn't enrolled in Medicare?
Medicare pays nothing at all, regardless of medical necessity. Enrollment in Medicare as a DME supplier is a strict prerequisite for any Medicare payment; using a non-enrolled supplier means the full cost falls on you, not a partial payment with balance billing.
What's the difference between a participating and non-participating DME supplier?
A participating supplier always accepts Medicare assignment, meaning they accept the Medicare-approved amount as full payment and can only collect your deductible and 20% coinsurance. A non-participating supplier can choose, claim by claim, whether to accept assignment; when they don't, they can bill you more than the Medicare-approved amount, on top of the standard coinsurance.
