Medicare Durable Medical Equipment Coverage: A Caregiver's Step-by-Step Guide

Your parent needs a wheelchair, and the retail price is $2,400. The medical supply store says Medicare might cover it, but your parent's doctor has never mentioned a Certificate of Medical Necessity. Nobody at the supplier can tell you exactly what paperwork is required or how long approval takes. This is the reality of Medicare DME coverage — a system that funds billions in medical equipment annually but buries the process behind clinical requirements most families have never heard of.

Here is exactly how it works, what qualifies, and the steps that protect you from paying full price out of pocket.

What Medicare Part B Covers as DME

Medicare Part B covers equipment that meets all four criteria: it can withstand repeated use, it serves a medical purpose, it is not useful to someone without an illness or injury, and it is appropriate for use in the home. That last point — "in the home" — is the requirement that catches most families. Equipment prescribed solely for use outside the home (like a scooter for shopping trips) does not qualify.

Covered equipment includes: manual wheelchairs, power wheelchairs (with additional clinical documentation), hospital beds, patient lifts, walkers, canes, crutches, seat-lift mechanisms for lift chairs, continuous positive airway pressure (CPAP) devices, nebulizers, and oxygen equipment.

Not covered: bathtub grab bars, shower chairs (usually classified as convenience items unless medically justified), raised toilet seats, stair lifts, and home modifications like ramps or widened doorways.

Does Medicare Cover Wheelchairs?

Yes, but the process requires more documentation than most families expect. For a manual wheelchair, your parent's physician must conduct a face-to-face examination, document that your parent has a mobility-related activity of daily living (MRADL) limitation inside the home, and determine that the limitation cannot be resolved by a cane or walker alone.

For a power wheelchair or scooter, Medicare requires an even higher bar: a detailed face-to-face examination by a physician or qualified practitioner, written documentation that the patient cannot perform at least one MRADL (toileting, feeding, dressing, grooming, or bathing) inside the home without the power device, and a comprehensive physical home assessment confirming that doorways, hallways, and floor plans can physically accommodate the chair. The prescription must be written within 45 days of the face-to-face exam.

Approval and delivery for power mobility devices typically takes 4 to 6 weeks.

Does Medicare Cover Walkers and Rollators?

Medicare covers standard walkers when prescribed by a physician as medically necessary. Rollators (wheeled walkers with hand brakes and a seat) are also covered, but Medicare classifies them differently from standard walkers. The physician must specifically document why a rollator is needed instead of a basic walker — typically because the patient requires the wheels for propulsion due to upper body weakness or the seat for rest during ambulation.

If the doctor's prescription just says "walker" without specifying a rollator, the supplier will default to a basic model. Make sure the prescription matches the specific device your parent needs.

The 80/20 Coinsurance Split

After meeting the annual Part B deductible ($240 in 2026), Medicare pays 80% of the Medicare-approved amount. Your parent pays the remaining 20%. If your parent has a Medigap supplemental policy, the 20% coinsurance may be partially or fully covered depending on the plan.

For expensive items like power wheelchairs, that 20% coinsurance can still be significant. A $4,000 power wheelchair leaves $800 out of pocket after Medicare's 80% contribution. Verify your parent's supplemental coverage before committing to a purchase.

The Capped Rental Rule

For items like manual wheelchairs and hospital beds, Medicare uses a "capped rental" structure. Instead of buying the equipment outright, Medicare rents it for 13 consecutive months. During months 1–3, your parent pays 20% of the rental cost each month. During months 4–13, ownership gradually transfers. After month 13, the equipment belongs to your parent, and Medicare stops paying — but the supplier is responsible for maintenance and repairs for the remainder of the five-year reasonable useful life.

If your parent's condition improves and they no longer need the equipment before month 13, they can return it and the rental payments stop.

Lift Chair Insurance Coverage

Medicare covers only the seat-lift mechanism of a lift chair (the motor that tilts the chair forward to assist with standing), classified under code E0627. It does not cover the chair itself — the frame, upholstery, and reclining mechanism are excluded. In practice, this means Medicare reimburses a fraction of the total lift chair cost, and the family pays the difference.

The physician must document that the parent has a severe arthritis condition or neuromuscular disease that makes standing from a seated position impossible without mechanical assistance. A generic note about difficulty standing is usually insufficient for approval.

The Four Steps to Get DME Covered

Step 1: Schedule a face-to-face visit with a Medicare-enrolled physician. The doctor must examine your parent in person — telehealth evaluations do not satisfy this requirement for DME orders.

Step 2: The physician writes a detailed prescription specifying the exact equipment, the medical diagnosis, and a statement of medical necessity. For complex items (power wheelchairs, hospital beds), a separate Certificate of Medical Necessity (CMN) form is required.

Step 3: Take the prescription to a Medicare-enrolled DME supplier who accepts assignment. "Accepts assignment" means the supplier agrees to charge only the Medicare-approved rate — no excess billing above that amount. If the supplier does not accept assignment, your parent could owe significantly more.

Step 4: The supplier submits the claim to Medicare. Once approved, Medicare pays the supplier directly and bills your parent for the 20% coinsurance.
