Medicare Durable Medical Equipment Coverage Guide 2026

Yes - Medicare Part B covers durable medical equipment (DME) for use in your home when a doctor prescribes it as medically necessary. That broad statement covers an enormous range of products: power wheelchairs, walkers, hospital beds, TENS units for chronic pain, CPAP machines for sleep apnea, home oxygen systems, blood glucose monitors, insulin pumps, prosthetic limbs, and much more. What you pay, what documentation you need, and which suppliers you can use depend on a set of rules that most beneficiaries never learn until they get an unexpected bill.

This guide covers every major DME category, what Medicare pays vs. what you owe, the supplier enrollment requirement that trips up many patients, and what Medicare will never cover no matter what your doctor prescribes.

What Qualifies as DME Under Medicare

Medicare uses four tests to determine whether a product qualifies as durable medical equipment:

  1. Durable - able to withstand repeated use over time (not disposable or single-use)
  2. Medical purpose - used to serve a medical need, not for comfort or convenience
  3. Home use - appropriate for use in the home environment (not equipment used only in a clinical setting)
  4. Expected need of 3+ years - intended for long-term use, not a brief recovery

A wheelchair, hospital bed, or CPAP machine meets all four. A heating pad, grab bar, or gym equipment typically does not.

The prescribing doctor must certify that the item is medically necessary by completing a written order (also called a Certificate of Medical Necessity or CMN for certain items). Medicare will not pay if the documentation is missing or incomplete - this is one of the most common reasons DME claims are denied.

How Medicare Part B Pays for DME

Medicare Part B pays 80 percent of the Medicare-approved amount for covered DME after you meet the Part B deductible ($257 in 2026). You pay the remaining 20 percent coinsurance. If you have a Medigap Plan G or Plan N, your plan covers most or all of that 20 percent.

Renting vs. buying: Medicare generally follows a capped rental model for many items. For powered equipment (like power wheelchairs and certain respiratory devices), Medicare pays a monthly rental for 13 months, after which you own the equipment outright. For some items, Medicare gives you the option to purchase directly. Talk to your supplier about which applies to your specific equipment.

Medicare-enrolled suppliers: You must use a Medicare-enrolled DME supplier or Medicare will not pay anything. This is non-negotiable. Before ordering equipment, verify that the supplier accepts Medicare assignment - this means they agree to accept the Medicare-approved amount as payment in full and can only charge you the standard 20 percent coinsurance. Suppliers who do not accept assignment can charge you significantly more.

Competitive bidding: Medicare’s Competitive Bidding Program applies in certain geographic areas for high-use items like power wheelchairs, CPAP equipment, oxygen, and standard manual wheelchairs. In competitive bidding areas, you must use a contract supplier for the item to be covered. Non-contract suppliers in a competitive bidding area cannot bill Medicare for covered items. Medicare’s supplier directory at medicare.gov can tell you which suppliers in your area have contracts.

Mobility Aids

Manual Wheelchairs and Transport Chairs

Medicare covers manual (self-propelled) wheelchairs when you have a documented mobility limitation that prevents you from performing activities of daily living inside your home. Transport chairs (pushed by an attendant) may be covered when you lack the upper body strength to self-propel.

Your doctor must conduct a face-to-face examination and document the clinical need. For standard wheelchairs, prior authorization is not typically required, but the written order and documentation in your medical records must support the medical necessity.

Power Wheelchairs and Power-Operated Scooters

Medicare covers power wheelchairs (also called power-operated vehicles or POVs) when you have a severe enough mobility limitation that a manual wheelchair cannot meet your in-home mobility needs. The evaluation process is more intensive than for manual wheelchairs:

  • A face-to-face examination by your treating physician or a physical or occupational therapist
  • Documentation that you have tried and cannot use a manual wheelchair
  • In some cases, a home assessment to confirm you can safely use and charge the device in your living space

Power wheelchair codes range from K0800 (Group 1 standard) to K0899 (custom rehabilitative), and the Medicare-approved amount varies by code. Many power wheelchairs require prior authorization from Medicare before the claim will be processed.

Scooters: Three-wheeled and four-wheeled scooters (power-operated vehicles) are covered under the same medical necessity framework as power wheelchairs. You must be able to safely operate the controls and transfer on and off the scooter independently.

Walkers and Rollators

Standard walkers and rollators (wheeled walkers with hand brakes and a seat) are among the most commonly covered DME items. No prior authorization is required. Your doctor’s written order and medical record documentation are sufficient.

TENS Units for Pain Management

Transcutaneous electrical nerve stimulation (TENS) units deliver mild electrical pulses through electrodes on the skin to interrupt pain signals. Medicare Part B covers TENS units as DME for:

  • Chronic intractable back pain - when conservative treatments (medication, physical therapy) have not provided adequate relief
  • Acute post-operative pain - covered for a limited period following surgery
  • Osteoarthritis of the knee - covered when conservative management has been tried first

What Medicare requires for TENS coverage: a prescription from your doctor documenting the diagnosis, the specific pain condition, and that you have tried other treatments without adequate relief. Medicare generally covers a one-month trial first; if the trial demonstrates pain relief, Medicare will then cover the TENS unit as a purchase.

The TENS unit itself is a DME purchase. Replacement electrodes and batteries are covered as supplies. Medicare does not cover interferential stimulators (IFC) or neuromuscular electrical stimulators (NMES) under the same DME category - these have separate coverage rules.

Respiratory Equipment

CPAP and BiPAP Machines

Medicare covers continuous positive airway pressure (CPAP) machines for obstructive sleep apnea after a qualifying sleep study documents the diagnosis. The initial coverage period is a 3-month trial. After 3 months, your doctor must document that you are using the CPAP regularly (compliance data downloaded from the machine’s modem typically shows this) and that it is helping your symptoms. If compliance and benefit are not documented, Medicare will not continue paying for the rental.

For more detail on CPAP coverage requirements, compliance rules, and what happens if your machine breaks, see our Medicare CPAP and sleep disorder coverage guide.

BiPAP/BPAP machines (bilevel positive airway pressure) are covered for certain respiratory conditions beyond sleep apnea, including COPD with respiratory failure, obesity hypoventilation syndrome, and neuromuscular diseases affecting breathing. The documentation requirements are more extensive than for standard CPAP.

Home Oxygen

Medicare Part B covers home oxygen and oxygen equipment (concentrators, compressed gas systems, liquid oxygen, and portable units) when your blood oxygen saturation level is 88 percent or below (measured at rest, during sleep, or during exercise), as documented by a blood gas test or pulse oximetry ordered by your doctor.

Medicare pays for the oxygen equipment rental and the oxygen itself. After 36 months of rental, you own the oxygen equipment outright, and Medicare continues to pay for the oxygen and maintenance separately.

Nebulizers

Nebulizers (devices that convert liquid medication into a mist for inhalation) are covered when prescribed for asthma, COPD, cystic fibrosis, or other respiratory conditions. The nebulizer itself is a DME purchase; the medications used in it may be covered under Part B or Part D depending on the specific drug.

Hospital Beds

Medicare covers hospital beds for home use when your doctor documents that you need a bed with rails for safety, can’t get out of a standard bed without a motor assist, need to change the head or foot elevation frequently for a medical condition, or have been prescribed bed rest with leg elevation. The documentation must specify the clinical reason - “for comfort” or “patient preference” is not sufficient.

Semi-electric beds (adjustable head and foot sections with an electric motor) are covered when you need frequent position changes but can transfer independently. Full-electric beds (all adjustments motorized) are covered when you have limited ability to manually adjust positions. Standard non-motorized hospital beds are covered for most other qualifying situations.

Medicare generally rents hospital beds initially and may transition to purchase after 13 months.

Patient Lifts

Ceiling track lifts and hydraulic floor lifts (Hoyer lifts) are covered when you have a condition that prevents you from transferring from a bed or wheelchair without mechanical assistance. Your doctor must document that you require the lift for safe transfers and that a caregiver will be present to operate it.

Diabetes DME

Blood Glucose Monitors and Test Strips

Medicare Part B covers blood glucose monitors and test strips for all Medicare beneficiaries with diabetes who are prescribed insulin. For those managing diabetes with oral medications only (no insulin), coverage depends on specific clinical documentation.

The number of test strips covered per month depends on whether you use insulin: insulin-users who do not self-adjust doses get up to 100 strips per month; those who self-adjust may qualify for up to 300 strips per month with physician documentation.

Continuous Glucose Monitors (CGMs)

Medicare covers therapeutic CGMs (devices that continuously measure interstitial glucose and can be used instead of fingerstick testing) for beneficiaries on insulin therapy. The CGM and receiver are covered as DME; some CGM sensors may be covered under Part B as supplies. As of 2024, Medicare also covers CGMs for non-insulin-treated beneficiaries in certain clinical situations.

Insulin Pumps

External insulin infusion pumps are covered as DME when you have Type 1 or Type 2 diabetes requiring intensive insulin management, have been using multiple daily injections, and your doctor has documented the clinical need. The pump itself is covered as a DME rental/purchase; insulin delivered via the pump is covered under Part B (not Part D) as a drug directly administered through DME.

Prosthetics and Orthotics

Prosthetic devices (artificial limbs) and orthotics (braces) are covered when prescribed by a physician as medically necessary. This includes:

  • Above-knee and below-knee prosthetic limbs
  • Arm prosthetics
  • Foot and ankle-foot orthoses (AFOs)
  • Spinal braces (LSOs, TLSOs) for documented conditions
  • Compression stockings - only when you have lymphedema or an open venous ulcer; preventive compression stockings are not covered

Prosthetics and orthotics must be provided by a Medicare-enrolled prosthetist or orthotist.

What Medicare Does NOT Cover Under DME

Even if a doctor prescribes it, Medicare Part B will not pay for:

  • Grab bars, handrails, stairlifts, wheelchair ramps, or other home modifications
  • Air conditioners or air purifiers
  • Exercise equipment, even when prescribed for rehabilitation
  • Heating pads and hot packs (covered only in an outpatient therapy setting, not for home purchase)
  • Non-prescription aids like canes that do not require physician oversight
  • Electric scooters or mobility aids used primarily outdoors
  • Items that are primarily for comfort, safety, or convenience rather than medical treatment
  • Items covered under Part D (most drugs and some wound care supplies)

Medicare Advantage DME Coverage

Medicare Advantage plans must cover the same DME that Original Medicare covers, but the process works differently. You typically use your plan’s network of preferred DME suppliers. Prior authorization requirements may be stricter than Original Medicare. Some plans add extra DME benefits - for example, covering non-prescription items like grab bars or over-the-counter supplies that Original Medicare excludes.

If you are denied DME coverage by your Medicare Advantage plan, you have the right to appeal. The appeals process runs through the plan first, then to an independent review entity.

Prior Authorization

Medicare requires prior authorization before covering certain high-cost or frequently misused DME items:

  • Power wheelchairs (most codes)
  • Pressure-reducing support surfaces (specialty mattresses)
  • Transcutaneous electrical nerve stimulators (TENS) for certain conditions
  • Some respiratory equipment

Prior authorization means your supplier submits documentation to a Medicare administrative contractor before the equipment is delivered. Medicare reviews the documentation and issues a decision. If approved, the claim processes normally. If denied, you can appeal.

For items that do not require prior authorization, Medicare can still deny the claim after the fact if it determines the documentation does not support medical necessity. That denial can be appealed through Medicare’s standard appeals process.

What to Do If Your DME Claim Is Denied

If Medicare denies a DME claim, you will receive a Medicare Summary Notice (MSN) or Explanation of Benefits (EOB) explaining the reason. Common denial reasons include:

  • Missing Certificate of Medical Necessity
  • Non-enrolled supplier
  • Item not covered under DME (e.g., home modification)
  • Insufficient documentation of medical necessity
  • Duplicate claim

You have the right to appeal any Medicare denial. The first level of appeal (Redetermination) must be filed within 120 days of the denial notice. If that is denied, you can escalate to a Qualified Independent Contractor (QIC) review, then to the Medicare Appeals Council, and ultimately to federal court if needed.

Frequently Asked Questions

Does Medicare cover TENS units for back pain? Yes - Medicare Part B covers TENS units as DME for chronic intractable back pain when conservative treatments have not provided adequate relief. Your doctor must prescribe the unit and document the failed prior treatments. Medicare typically covers a 1-month trial first.

Does Medicare cover a walker or rollator? Yes - Medicare Part B covers standard walkers and rollators when prescribed by your doctor as medically necessary. No prior authorization is required. You pay 20 percent coinsurance after the Part B deductible.

Does Medicare cover a power wheelchair or scooter? Yes - Medicare Part B covers power wheelchairs and power-operated scooters when you have a documented mobility limitation that cannot be met with a manual wheelchair. The evaluation process is more involved and many codes require prior authorization.

Does Medicare cover a hospital bed at home? Yes - Medicare Part B covers hospital beds for home use when your doctor documents a specific clinical need (safety rails, frequent position changes, prescribed bed rest with elevation). Personal preference alone is not sufficient.

Does Medicare cover blood pressure monitors at home? No - home blood pressure monitors are not covered as DME under Medicare Part B. They are considered a convenience item. Some Medicare Advantage plans may cover them as an extra benefit.

How do I find a Medicare-enrolled DME supplier? Use the Supplier Directory at medicare.gov/care-compare, or call 1-800-MEDICARE. Always confirm before ordering that the supplier is enrolled and accepting Medicare assignment in your area, especially in competitive bidding areas.

Can Medicare cover DME for items I use outside the home? Generally no - DME coverage is limited to items used in the home. Items like portable oxygen concentrators may be covered if the primary use is in the home and the portable unit is an extension of home-based treatment.

What if I need DME quickly - can I get it delivered before prior authorization is approved? If your condition requires immediate equipment, your supplier can provide it on a provisional basis and submit the authorization simultaneously, taking the risk that it may be denied. Discuss this option with your supplier and understand your financial liability if the authorization is not approved.
