Medicare and medical devices: Coverage, options, and costs

If you’ve ever tried to decode a Medicare bill for a walker, CPAP machine, or continuous glucose monitor and thought, “This feels like advanced math,” you’re not alone. Medical devices can be expensive, and the way Medicare pays for them can seem mysterious. The good news: once you understand a few basic rules, the system starts to make senseand you can save real money.

This guide breaks down how Medicare covers medical devices (especially durable medical equipment), what your options look like under Original Medicare and Medicare Advantage, and how much you’re likely to pay out of pocket. We’ll also walk through ways to keep costs down and highlight a few real-world examples to bring the rules to life.

How Medicare thinks about medical devices

Medicare doesn’t use the phrase “medical gadget that makes life easier.” It mainly talks about durable medical equipment (DME), plus related prosthetic and orthotic devices.

What is durable medical equipment?

Under Medicare, DME is equipment that:

• Is used for a medical reason (not just comfort or convenience).
• Can withstand repeated use over time.
• Is generally expected to last at least three years or more.
• Is appropriate for use in the home environment, not only in a hospital or facility.

Examples include walkers, wheelchairs, hospital beds, home oxygen equipment, CPAP machines, blood sugar meters, continuous glucose monitors (CGMs), and certain infusion or insulin pumps.

“Reasonable and necessary” matters

Another big phrase in Medicare world is “reasonable and necessary.” Medicare only covers items that fit within one of its benefit categories (like DME) and are considered medically necessary for your diagnosis or treatment. National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs) spell out when specific deviceslike CGMs or power wheelchairsare covered.

For some devices, your provider may need to complete extra documentation, such as a certificate of medical necessity, to explain exactly why you need that equipment.

Where device coverage lives in the Medicare alphabet

Medicare Part A: Devices in the hospital or facility

Part A generally covers inpatient carehospital stays, skilled nursing facilities, and some home health and hospice care. Medical devices you use while an inpatient (like IV pumps or monitors at the bedside) are usually bundled into the facility payment. You don’t get separate bills for that equipment.

However, when you’re sent home with equipmentlike a walker or home oxygenthat’s usually a Part B story, not Part A.

Medicare Part B: The main home for DME

Part B is where most medical devices live. Part B covers:

• Durable medical equipment (DME) used at home.
• Prosthetic and orthotic devices.
• Diabetes supplies and equipment, including blood glucose meters, some pumps, and CGMs that qualify as DME.

In 2025, after you meet the Part B annual deductible of $257, Medicare typically pays 80% of the Medicare-approved amount for covered DME, and you pay the remaining 20% coinsurance.

Your costs are lowest when you:

• Use a Medicare-approved supplier, and
• That supplier accepts assignment (agrees to take Medicare’s approved amount as full payment).

Medicare Advantage (Part C): Same benefits, different rules

Medicare Advantage plans (Part C) must cover at least the same DME benefits as Original Medicare, but they can set their own networks and cost-sharing rules. That means:

• You’ll typically have to use in-network DME suppliers.
• Instead of a 20% coinsurance, you might pay a flat copay or a different percentage depending on the plan.
• Plans have an annual out-of-pocket maximum, which can help limit your total spending in a high-need year.

Always check your plan’s Evidence of Coverage for the exact copays and rules for medical devices.

Medicare Part D: Drugs and some supplies

Part D usually handles prescription drugs, not equipment. However, some supplies linked to medicationssuch as certain insulin pen needles or syringesmay be covered under your Part D plan instead of Part B. When in doubt, your pharmacist or plan can tell you whether a supply is considered a DME benefit or a drug-related benefit.

Common medical devices Medicare covers

Here are some of the most common categories of Medicare-covered devices. Exact coverage always depends on your diagnosis and your provider’s order, but this list gives a real-world sense of what’s typical.

Mobility aids

• Canes and crutches
• Standard and lightweight wheelchairs
• Power wheelchairs and scooters (for people who can’t use a manual chair inside the home)
• Walkers and rollators

Breathing and sleep equipment

• Home oxygen equipment and accessories
• Nebulizers and some related medications
• CPAP and BiPAP machines for sleep apnea

Diabetes devices

• Blood glucose meters and test strips
• Continuous glucose monitors (CGMs), when you meet Medicare criteria
• Certain insulin pumps and supplies

Other equipment and supplies

• Hospital beds for home use
• Infusion pumps
• Commode chairs and shower chairs (in some cases)
• Prosthetic limbs and certain prosthetic devices
• Orthotic braces
• Ostomy and some wound-care supplies

Not every device you see in a TV ad will qualify. Items that are primarily for comfort, convenience, or general healthlike air purifiers, home grab bars, or most fitness equipmenttypically aren’t covered as DME.

What you need for Medicare to pay

Getting coverage isn’t just about wanting the equipment; it’s about checking the right boxes. In general, you’ll need:

• A face-to-face visit with a Medicare-enrolled doctor or qualified provider.
• A written order or prescription for the device.
• Documentation that the device is medically necessary for your condition and will be used in your home.
• A Medicare-enrolled supplier that provides the equipment.

For some high-cost items (like power wheelchairs and certain pumps), documentation may get especially detailed. Don’t be surprised if your doctor’s office and the supplier go back and forth on paperwork; that’s often about satisfying coverage rules, not doubting your needs.

Renting vs. buying medical equipment

One of the most confusing parts of Medicare and devices is whether you’re renting or buying the equipment. Medicare has specific rules for this:

When you rent

• For many deviceslike hospital beds or oxygen equipmentMedicare will usually rent the equipment through a supplier.
• Medicare makes monthly payments to the supplier, and you pay your 20% share each month after the deductible.
• For many items, rental is capped after about 13 months of continuous use. After that, you generally own the item, and the supplier may then be responsible for certain maintenance.

When you buy

• Some items are designated as “purchase” items; others allow you to choose to buy instead of rent if you’ll need them long term.
• If Medicare approves the purchase, it usually pays 80% of the Medicare-approved price after the deductible, and you pay 20%.
• If the equipment is damaged beyond repair, lost, or has exceeded its “reasonable useful lifetime” (often around five years), Medicare may help pay for a replacement when medically necessary.

Repairs for purchased equipment are also covered: Medicare generally pays 80% of the Medicare-approved repair cost (up to the cost of replacing the item), and you pay 20%.

How much will you actually pay?

Your out-of-pocket costs depend on several layers: the type of device, where you get it, what type of Medicare coverage you have, and whether you carry supplemental insurance.

Under Original Medicare (Parts A and B)

Let’s say your doctor orders a walker, and you have Original Medicare with no Medigap plan:

• You pay the annual Part B deductible ($257 in 2025) if you haven’t already met it.
• After that, Medicare pays 80% of the Medicare-approved cost of the walker.
• You pay the remaining 20% coinsurance.

If the walker costs more than the Medicare-approved amount and your supplier doesn’t accept assignment, you could owe more than 20%. That’s why picking a participating supplier is so important.

How Medigap can help

If you have a Medigap (Medicare supplement) plan along with Original Medicare, your plan may cover some or all of that 20% coinsurance for DME, and possibly even the Part B deductible, depending on the specific plan.

In practical terms, that means your walker, CPAP machine, or CGM could end up costing you little or nothing out of pocket beyond your Medigap premium, as long as the device itself is covered and you follow Medicare rules.

Under Medicare Advantage plans

With a Medicare Advantage plan, your costs might look different:

• You may pay a flat copay (for example, $30 or $50 per month for rented equipment).
• You could instead pay a different coinsurance percentage (like 10% or 35%), depending on the plan’s design.
• All of those costs count toward your plan’s annual out-of-pocket maximum, which Original Medicare does not have.

Because each Medicare Advantage plan sets its own device cost-sharing, checking the plan’s DME section before ordering equipment is crucial.

Special case: CGMs, insulin pumps, and other high-tech devices

Diabetes technology is a fast-moving area where coverage rules have expanded in recent years. Medicare now covers several types of continuous glucose monitors (CGMs) as DME under Part B when you meet certain criteriatypically having diabetes, using insulin or meeting hypoglycemia requirements, and having a provider’s prescription.

Some insulin pumps and their supplies also fall under DME, while insulin used with those pumps may be billed differently than insulin taken with pens or syringes. These details matter because they affect whether your costs follow Part B rules (80/20 after the deductible) or Part D drug rules.

Bottom line: if you use high-tech devices, ask your endocrinologist’s office or diabetes educator to clarify exactly how your specific device is billed under Medicare.

Strategies to manage medical device costs

1. Choose the right Medicare path for your needs

If you expect to need multiple devices or long-term equipment (such as a power wheelchair, hospital bed, or home oxygen), it may be worth comparing:

• Original Medicare + Medigap, which can dramatically reduce your DME coinsurance, versus
• Medicare Advantage, which might have lower premiums but different copays and networks for equipment.

2. Stick with Medicare-approved suppliers

Using a non-participating supplier might look cheaper up front, but it can cost more in the long run if they bill above the Medicare-approved amount. When possible, ask the supplier two key questions:

• “Are you a Medicare-enrolled supplier?”
• “Do you accept assignment for this equipment?”

3. Ask whether rental or purchase is better

If you’re likely to need a device only for a short timesay, a walker after surgeryrenting via Medicare can make sense. If you’ll use the device for years, purchasing might be cheaper overall. Your doctor, supplier, and plan can help you understand which options are allowed for your specific equipment.

4. Look for additional help programs

Depending on your income and assets, you might qualify for:

• Medicaid or a Medicare Savings Program, which can help pay premiums and sometimes reduce cost-sharing.
• State or local programs that help with equipment for people with disabilities.
• Manufacturer assistance programs for certain types of devices.

Watch out for “free” equipment scams

If someone calls and says, “Hi, we’re from Medicare and we’d like to send you a free back brace,” that’s your cue to hang up. Medicare does not randomly call people to offer free equipment. Scammers often use these tactics to steal your Medicare number and bill Medicare for expensive items you never asked foror that are poor quality.

To protect yourself:

• Never give your Medicare number to strangers over the phone or at community events.
• Refuse unsolicited offers of “free” devices.
• Check your Medicare Summary Notices for equipment you didn’t receive.
• Report suspicious activity to Medicare or your state’s Senior Medicare Patrol program.

Real-world experiences with Medicare and medical devices

Rules and percentages are helpful, but it’s often easier to understand Medicare when you see how it works for real people. Here are a few typical situations and what they might look like in practice (names changed, details simplified).

Maria and her CPAP machine

Maria is 68 and has Original Medicare plus a Medigap Plan G. After years of snoring and daytime fatigue, she’s diagnosed with sleep apnea. Her doctor orders a sleep study and prescribes a CPAP machine.

Because Maria uses a Medicare-approved supplier that accepts assignment, Medicare Part B covers 80% of the machine’s rental cost after she meets her deductible. Her Medigap plan picks up the remaining 20% coinsurance. For Maria, the biggest “cost” ends up being the adjustment periodgetting used to sleeping with a maskrather than the actual bills. Her takeaway: picking a Medigap plan that covers Part B coinsurance makes devices like CPAP essentially “budgetable” through premiums instead of surprise invoices.

James and the power wheelchair

James, 74, has severe arthritis and heart disease. Walking even short distances is difficult. His doctor documents that he can’t use a walker or standard wheelchair safely at home. After a detailed face-to-face visit and multiple forms, James is approved for a power wheelchair.

James has a Medicare Advantage plan. The plan requires him to use an in-network DME supplier and charges a percentage of the cost as coinsurance. The wheelchair is expensive, so even with coverage, his share is a few hundred dollars. However, the plan has an annual out-of-pocket maximum. Between the wheelchair and his other medical costs, James hits that cap for the yearso additional covered medical services cost him little or nothing.

His lesson: big-ticket devices can accelerate how quickly you reach a Medicare Advantage out-of-pocket maximum, which can be both painful and protective at the same time.

Linda, CGMs, and paperwork

Linda, 66, lives with type 2 diabetes and uses multiple daily insulin injections. She and her endocrinologist decide a continuous glucose monitor would help her manage blood sugar swings. Under today’s rules, Medicare can cover certain CGMs as DME when criteria are met and documentation is complete.

Her provider sends a detailed prescription and clinical notes to a DME supplier. There’s some back-and-forth on paperwork, but once approved, Medicare Part B covers 80% of the CGM system after Linda meets the deductible. She has no Medigap policy, so she pays the 20% coinsurance out of pocket. Still, she finds the device worth it: better glucose control, fewer surprises, and fewer trips to the lab for A1C tests.

Linda’s tip: for tech-heavy devices like CGMs and pumps, expect a little administrative frictionand make sure your doctor’s office knows how to navigate Medicare’s rules.

Sam and the mysterious “free knee brace”

Sam gets a call one afternoon from someone claiming to be “with Medicare,” offering a free knee brace if he just confirms his Medicare number. It sounds convenient; his knee has been sore lately. But something feels off, so he hangs up and later calls Medicare directly. They confirm it was a scam.

A few weeks later, Sam reviews his Medicare Summary Notice and sees a charge for a brace he never received. He calls Medicare again and reports the fraud. The charge is investigated, and he’s not held responsible for the bogus claim.

Sam’s message: if an offer sounds too good to be trueand especially if it involves your Medicare numberit probably is. Always go through your doctor and known suppliers for equipment.

Bringing it all together

Medical devicesfrom simple walkers to sophisticated glucose monitorscan dramatically improve quality of life. Medicare does pay for a wide range of these tools, but it does so with detailed rules: the device has to be durable, medically necessary, prescribed by a provider, and obtained from the right kind of supplier.

Once you understand where coverage lives (mostly in Part B), how coinsurance works, and what your supplemental coverage looks like, you can make smarter decisions about whether to rent or buy, which plan to choose, and how to avoid surprise billsor shady “free equipment” offers.

In other words: the system might be complex, but it’s not random. Learn the rules, ask good questions, and treat your devices as part of a broader strategy to protect both your health and your wallet in retirement.
