U.S. Medicare and Durable Medical Equipment in 2026: 20% Coinsurance

Yes, Medicare Part B covers medically necessary durable medical equipment for home use, including walkers, wheelchairs, oxygen equipment, and hospital beds. After you meet your annual Part B deductible, you generally pay 20% of the Medicare-approved amount if your supplier accepts assignment. You also need a written order from a treating provider and a Medicare-enrolled supplier to get coverage.

TL;DR:

• Medicare Part B covers durable medical equipment only if it is durable, medically necessary, appropriate for home use, and lasts at least three years.
• Most equipment is rented first, with some converting to ownership after a set number of payments, and requires a face-to-face exam or prior authorization for complex devices.
• Cost-sharing in 2026 involves a deductible followed by a 20% coinsurance, with costs higher if the supplier does not accept assignment.
• Verification of Medicare enrollment and supplier acceptance of assignment is crucial to avoid unexpected bills or fraud risks.
• A denied claim can often be appealed through the Medicare redetermination process by providing documentation from your provider and supplier.

What Medicare Considers Durable Medical Equipment

Medicare uses a specific definition, and an item has to check every box to qualify. According to Medicare, durable medical equipment must be durable enough for repeated use, serve a medical purpose, be useless to someone who isn’t sick or injured, be appropriate for home use, and generally last at least three years.

That definition shapes how Medicare pays for items, and payment structure varies by category:

• Rental first: Oxygen equipment and CPAP machines are typically rented on a monthly basis rather than purchased outright.
• Rent-to-own: Many items convert to your ownership after a set number of rental payments, so you stop paying once that threshold is reached.
• Trial periods apply to some items: CPAP therapy usually starts with a 12-week trial before Medicare commits to ongoing coverage.
• Face-to-face exams matter for complex equipment: Power wheelchairs and scooters often require an in-person visit with your doctor before a supplier can bill Medicare.

These item-specific rules exist because Medicare wants documented proof that the equipment is helping before it pays for the long term.

Eligibility and Documentation: What You, Your Provider, and Your Supplier Must Do

Coverage depends on more than just having Part B. You need the right paperwork in the right order, and each party in the process has a job to do.

1. Enroll in and maintain Part B. Durable medical equipment falls under Part B, not Part A, so active enrollment is the starting point.
2. Get a written order from your treating provider. This order has to describe your condition and explain why the equipment is medically necessary for use in your home.
3. Complete a face-to-face exam when required. Some items, particularly powered mobility equipment, need a documented in-person visit before a supplier can submit a claim, and some now require prior authorization before Medicare will pay.
4. Choose a Medicare-enrolled supplier that accepts assignment. Skipping this step is one of the most common reasons beneficiaries end up with bills they didn’t expect.

Common DME Items Medicare Covers by Category

Medicare’s covered equipment list is broad, but coverage details differ by category. Knowing where your item falls helps you anticipate what documentation or waiting period applies.

• Mobility equipment: Canes, walkers, manual wheelchairs, power wheelchairs, and scooters are covered, though power mobility devices often require prior authorization and a face-to-face exam.
• Respiratory equipment: Oxygen equipment and CPAP machines are covered under rental arrangements, with CPAP starting with a trial period and oxygen typically on a 36-month rental schedule that keeps supplies and refills covered for up to five years.
• Hospital beds and pressure-reducing support surfaces: These items are covered when medically necessary, and certain pressure-reducing support surfaces now fall under expanded prior authorization rules.
• Other covered items: Diabetic testing supplies, infusion pumps, commodes, crutches, bracing, and lymphedema compression devices round out the list of commonly covered equipment.

Each category comes with its own paperwork expectations, so confirming the specific rule for your item before you order it saves time later.

Getting DME Covered: A Step-by-Step Process

Following a consistent process reduces the chance of a denied claim or a surprise bill. Here is the order that tends to work best.

1. Get a written order from your treating provider. Make sure it documents your diagnosis, your functional limitation, and why the equipment is needed at home.
2. Ask whether a face-to-face exam or prior authorization applies. Your provider’s office can tell you if your item is on the expanded prior authorization list, and schedule any required visit promptly.
3. Search for a supplier using the Medicare.gov supplier tool. Confirm the supplier is Medicare-enrolled and, just as important, confirm they accept assignment before you agree to anything.
4. Review rental versus purchase terms in writing. Ask how many rental payments lead to ownership, what happens if you need a repair during the rental period, and get the answer in writing before delivery.

Pro Tip: Call the supplier’s billing office directly and ask them to confirm assignment status in writing, since verbal assurances are easy to dispute later if a bill arrives that doesn’t match what you were told.

How Much You Can Expect to Pay and Billing Red Flags

Medicare Part B carries a defined annual deductible in 2026, and once you meet it, DME coverage generally leaves you responsible for 20% of the Medicare-approved amount when your supplier accepts assignment. That 20% coinsurance applies to the Medicare-approved rate, not the supplier’s sticker price, which is exactly why assignment status matters so much.

A few things to watch for before you sign anything:

• Assignment changes your math. A supplier that accepts assignment agrees to the Medicare-approved amount as full payment aside from your coinsurance; one that doesn’t can bill you more, sometimes well above that rate, as explained in our piece on Medicare excess charges.
• Competitive bidding can lower your costs but narrow your options. Contract suppliers in the DMEPOS competitive bidding program often charge less, but you may have fewer brand or model choices in bid areas.
• Red flags to walk away from: demands for full payment upfront on rented equipment, refusal to confirm assignment, and vague answers about when a rental becomes a purchase.

2026 Updates: Prior Authorization and Supplier Program Changes

CMS made real changes to the DME process for 2026, and they affect timing as much as eligibility.

• New prior authorization requirements took effect October 28, 2026. Certain orthoses, pressure-reducing support surfaces, and a manual wheelchair base joined the list of items requiring prior authorization before Medicare will pay a claim.
• Newly enrolled suppliers face a probationary prior authorization period starting October 15, 2026. This gives CMS a chance to review new suppliers’ claims more closely before they build a full billing history.
• Ask your supplier directly whether your item needs prior authorization. Suppliers typically handle the submission, but confirming it happened, and that your provider documented the face-to-face encounter, prevents a denial you didn’t see coming.

If Your Claim Is Denied: What to Do Next

A denial isn’t the end of the road, but acting quickly matters.

1. Ask the supplier and your provider for the specific denial reason and any supporting documentation on file. This tells you whether the issue is missing prior authorization, insufficient medical necessity documentation, or something else entirely.
2. File a redetermination request, the first of five appeal levels. Each level has its own deadline, so start promptly rather than waiting to see if the bill resolves itself.
3. Gather your provider’s notes, the original written order, and any supplier communications. A complete file at the first level often resolves the issue before you need to escalate further.

Maintenance, Repair, and Replacement Rules for DME

Equipment wears out, and Medicare has rules for what happens next. For equipment you rent, the supplier is generally responsible for maintenance and repairs during the rental period as part of the monthly payment, so you shouldn’t be billed separately for routine upkeep.

Once you own an item outright, either because you purchased it directly or completed a rent-to-own period, Medicare Part B can help cover repairs needed to keep it functioning, along with replacement parts when something breaks. Labor and parts both typically fall under the same 20% coinsurance structure that applies to the original equipment, once your deductible is met.

Replacement of the entire item is more limited. Medicare generally expects durable equipment to last at least five years, and replacing it sooner usually requires documentation showing the item was lost, stolen, or damaged beyond repair, or that your medical condition has changed enough to need different equipment. Routine wear alone after five years is usually enough to justify a new order from your provider.

Before assuming a repair or replacement will be covered, ask your supplier whether the item is still within its expected lifespan and what documentation your provider needs to submit. Skipping that step is a common reason replacement claims get delayed or denied.

Avoiding Fraud and Scams With DME Suppliers

DME fraud shows up in some predictable patterns, and knowing them protects both your wallet and your Medicare benefits. Scammers often call offering free braces, scooters, or glucose monitors in exchange for your Medicare number, then bill Medicare for equipment you never ordered or never received.

A few habits lower your risk significantly. Never give your Medicare number to anyone who contacts you first, whether by phone, text, or a booth at a community event. Legitimate suppliers work through your treating provider’s order, not cold outreach. Always review your Medicare Summary Notice for equipment you don’t recognize, and question any charge for an item you never requested.

Work only with suppliers you can verify through the Medicare.gov supplier search tool, and be cautious of any supplier pushing you toward equipment you didn’t ask for or didn’t discuss with your doctor. If something feels off, such as a supplier offering to waive your coinsurance or coaching you on what to tell Medicare, treat that as a warning sign rather than a convenience.

If you suspect fraud, report it. Keeping your Medicare Summary Notices and comparing them against what you actually received is the simplest ongoing safeguard against billing for equipment that was never delivered or never needed.

Checking Supplier Quality Ratings Before You Order

Not all Medicare-enrolled suppliers offer the same level of service, and a little research before you order can save you a frustrating rental experience. Start with the Medicare.gov supplier search, which confirms Medicare enrollment and assignment status, the two most important facts before you commit to any supplier.

Beyond that basic verification, check whether a supplier holds accreditation from a recognized accrediting organization, since Medicare requires DME suppliers to meet quality standards to stay enrolled. Online reviews on general platforms can offer a sense of a supplier’s responsiveness and reliability, though treat them as one data point rather than the full picture, since review volume for medical equipment suppliers tends to be smaller than for consumer products.

It also helps to ask direct questions before you order: how quickly they deliver, who to call for repairs during a rental period, and whether they handle prior authorization paperwork themselves or expect you to coordinate with your provider’s office. A supplier’s willingness to answer these clearly, before you’ve committed to anything, tends to say as much about their service quality as any star rating.

FAQ

What durable medical equipment will Medicare pay for?

Medicare Part B pays for equipment that is durable, medically necessary, appropriate for home use, and expected to last at least three years, including walkers, wheelchairs, hospital beds, oxygen equipment, and CPAP machines. Diabetic supplies, commodes, crutches, and bracing are also commonly covered. Coverage requires a written order from your treating provider and a Medicare-enrolled supplier.

What items does Medicare typically exclude from DME coverage?

Medicare generally won’t cover items meant for comfort or convenience rather than medical necessity, equipment primarily useful to someone who isn’t sick or injured, or items that don’t meet the durability and home-use criteria Medicare.gov describes. Disposable items outside specific supply categories, equipment ordered without a qualifying provider visit, and claims missing required prior authorization are also common reasons for denial. If you’re unsure whether an item qualifies, ask your provider before ordering.

How much does DME cost under Medicare in 2026?

After you meet your 2026 Part B deductible, you typically pay 20% of the Medicare-approved amount for covered DME if your supplier accepts assignment. Costs can be higher if your supplier doesn’t accept assignment, since they can charge above the Medicare-approved rate.

What are the billing rules suppliers must follow for DME?

Suppliers must be enrolled in Medicare and, for many items, must obtain required prior authorization before submitting a claim under the rules CMS expanded in 2026. Suppliers that accept assignment agree to bill Medicare directly and accept the Medicare-approved amount as full payment aside from your coinsurance. Always confirm a supplier’s assignment status before accepting delivery of equipment.

What should I do if Medicare denies my DME claim?

Start by asking your supplier and provider for the specific denial reason and any documentation already on file. From there, file a redetermination request, the first of the five levels in the Medicare appeals process, and include your provider’s notes and the original order to support your case.
