Durable Medical Equipment (DME): What Medicare Covers

Durable Medical Equipment, usually called DME, includes certain reusable medical items prescribed for use in your home, such as walkers, wheelchairs, oxygen equipment, and hospital beds. Under Original Medicare, DME is generally covered by Part B when it is medically necessary, ordered by a doctor or other provider, and obtained through a Medicare-enrolled supplier.

What is durable medical equipment?

Medicare describes DME as medical equipment ordered for use in the home. Common examples on Medicare’s official coverage pages include walkers, wheelchairs, scooters, oxygen equipment, and hospital beds.

In plain English, DME usually has a few key traits: it is medically necessary, reusable, and meant to help you manage a condition or function more safely at home. Medicare’s DME booklet and coverage pages also note that coverage rules can differ by item, including whether equipment is rented, purchased, or offered with a rent-versus-buy choice.

What does Medicare usually cover?

Medicare Part B may cover DME if your doctor or other health care provider prescribes it for use in your home and the item meets Medicare’s rules. Medicare’s official DME coverage page specifically says eligibility depends on medical necessity and a prescription, and stresses that both the doctor and supplier should be enrolled in Medicare.

Examples of DME commonly covered by Medicare include:

• Walkers
• Wheelchairs and scooters
• Oxygen equipment and accessories
• Hospital beds
• Patient lifts
• Certain other medically necessary devices used in the home

Medicare also highlights some DME-related categories such as CPAP therapy, nebulizers and nebulizer medications, oxygen equipment, walkers, and wheelchairs or scooters as common coverage topics.

What Medicare does not automatically cover

This is where many people get surprised. Medicare does not simply cover an item because it would be helpful or convenient. Coverage usually depends on whether the item is medically necessary under Medicare’s rules and whether it is the kind of equipment Medicare classifies as DME.

That means Medicare may not cover:

• Equipment that is mainly for comfort or convenience
• Equipment not prescribed for use in the home
• Items obtained through suppliers that are not properly enrolled
• Items that do not meet Medicare’s medical-necessity rules

Do you rent or buy DME?

It depends on the type of equipment. Medicare says some DME must be rented, some must be bought, and some items let you choose whether to rent or buy. That is one reason two people with different equipment needs may have very different Medicare billing experiences.

If you rent equipment, Medicare’s booklet says the supplier is responsible for maintaining and repairing it so it stays in good working order. If you own the equipment, repair arrangements can work differently.

How much might you pay?

For covered DME under Part B, Medicare commonly applies the Part B deductible first, then you generally pay 20% of the Medicare-approved amount if the supplier accepts assignment. Medicare’s patient lift page states this directly, and Medicare’s general assignment page explains that accepting assignment means the supplier agrees to the Medicare-approved amount as full payment.

Your actual cost can still vary based on factors such as other insurance, the supplier you use, whether assignment is accepted, and the specific item involved. Medicare’s hospital bed coverage page says the amount you could owe depends on those kinds of factors.

Why supplier choice matters

One of the biggest DME mistakes people make is focusing only on the equipment and not the supplier. Medicare says you should make sure your doctor and DME supplier are enrolled in Medicare, and you should ask whether the supplier participates in Medicare or accepts assignment before you get the equipment.

If a DME supplier is not participating or does not accept assignment, you may pay more. Medicare’s wheelchair and scooter page warns that for rented DME, you should make sure the supplier will accept assignment for all rental months, and if the claim is not assigned, you may have to pay the full cost up front and wait for Medicare reimbursement later.

Medicare also offers an official supplier directory and Care Compare tools to help beneficiaries find Medicare-approved medical equipment suppliers.

Common mistakes people make with DME

Assuming every medically helpful item is covered

Medicare coverage is not based only on whether something seems useful. The item must meet Medicare’s DME rules and medical-necessity standards.

Ignoring the “for use in the home” rule

Medicare’s DME page repeatedly frames covered equipment as equipment prescribed for use in your home. That detail matters more than many people realize.

Using the wrong supplier

Even covered equipment can cost more than expected if the supplier is not enrolled in Medicare or does not accept assignment.

Assuming you can always buy instead of rent

Some DME must be rented, some bought, and some give you a choice. It depends on the item.

Questions to ask before you get DME

Before you accept equipment, ask:

• Has my doctor or provider prescribed this as medically necessary?
• Is this item covered by Medicare as DME?
• Is it for use in my home?
• Do I rent it, buy it, or choose?
• Is the supplier enrolled in Medicare?
• Does the supplier accept assignment?
• What will my out-of-pocket cost likely be?

Those questions can help you avoid delays, surprise bills, and equipment you thought was covered but is not.
