Medicare Part B covers wheelchairs when they’re medically necessary, meaning your doctor documents that you need one to move around your home. The process involves a face-to-face exam, a written prescription, choosing the right supplier, and understanding your share of the cost. Here’s how each step works.
What Medicare Considers Medically Necessary
Medicare doesn’t cover a wheelchair simply because it would make life easier. Coverage hinges on your ability to perform daily activities inside your home. Your doctor must answer four specific questions during your evaluation: What is your mobility limitation, and how does it interfere with daily activities like bathing, dressing, or getting to the bathroom? Why wouldn’t a cane or walker solve the problem? Why wouldn’t a manual wheelchair work? And can you safely operate the device you’re requesting?
That last question matters more than people expect. For a power wheelchair, all three of these conditions must be met: you’re essentially bed- or chair-bound without a wheelchair, your condition makes a wheelchair medically necessary and you can’t propel a manual one (typically due to severe upper-body weakness from a neurological or muscular condition), and you’re physically and mentally able to operate power controls safely. If a manual wheelchair would meet your needs, Medicare will cover that instead.
The Face-to-Face Exam
Before Medicare will pay for any wheelchair, you need a face-to-face examination with your treating provider. This isn’t a quick check-in. The visit must be specifically focused on your mobility, and the doctor needs to document it as a detailed narrative note in your medical record. That note should cover your medical history as it relates to mobility, plus a physical exam including your weight, height, heart and lung status, musculoskeletal function, and neurological condition.
The purpose is to build a clear medical case that a wheelchair is the right solution for you, not just a convenience. Your doctor will evaluate whether less complex equipment (a cane, walker, or manual chair) could work first, and document why it can’t.
Timelines You Need to Follow
Medicare enforces strict deadlines that can derail your claim if you miss them. Within 45 days of your face-to-face exam, your doctor must send the exam documentation and a completed written prescription to your wheelchair supplier. The supplier then has to deliver the wheelchair within 120 days of the original exam date. If delivery doesn’t happen within that window, you’ll need to start over with a new face-to-face exam to confirm the wheelchair is still appropriate for your condition.
These timelines mean it’s worth coordinating with both your doctor’s office and the supplier early. Don’t wait weeks after your exam to start shopping for equipment.
Prior Authorization for Power Wheelchairs
Manual wheelchairs don’t require prior authorization, but many power wheelchairs and scooters do. Prior authorization means Medicare reviews your documentation and approves coverage before the equipment is delivered. If you skip this step for a chair that requires it, you risk being stuck with the full bill.
The categories that need prior authorization include standard, heavy-duty, very heavy-duty, and extra heavy-duty power wheelchairs across multiple groups, as well as power-operated vehicles (scooters). Your supplier should know which codes require approval, but it’s worth confirming. A prior authorization request can be denied if Medicare determines you don’t medically need the device or if the submitted documentation is incomplete.
The Home Assessment
Your home has to physically accommodate the wheelchair you’re requesting. Medicare requires a home assessment that addresses the layout of your living space, the surfaces you’d be rolling across, doorway widths, and any obstacles. For manual wheelchairs, this assessment can be done in person by a supplier visiting your home or indirectly based on information you provide. For power wheelchairs, expect a more thorough evaluation. The results must be documented in your medical record or the supplier’s files.
This step exists because Medicare covers wheelchairs for home use specifically. If the chair you’re requesting can’t physically navigate your hallways or fit through your bathroom door, the claim won’t hold up.
Choosing the Right Supplier
Where you get your wheelchair matters as much as the prescription itself. Medicare-enrolled suppliers fall into two categories: those who “take assignment” and those who don’t. A supplier who takes assignment accepts Medicare’s approved payment amount as the full price. One who doesn’t can charge you above that amount, and Medicare will still only pay its standard 80%, leaving you responsible for the difference.
Then there are opt-out suppliers who haven’t signed up to bill Medicare at all. If you use one of these, Medicare pays nothing, and you owe the entire cost. The supplier should ask you to sign a private contract acknowledging this, but the safest approach is to search for participating suppliers at medicare.gov/supplier or call 1-800-MEDICARE before placing any order.
What You’ll Pay
Wheelchairs fall under Medicare Part B’s durable medical equipment benefit. After you meet the annual Part B deductible ($257 in 2025, rising to $283 in 2026), Medicare covers 80% of the approved amount. You pay the remaining 20% coinsurance. If you have a Medigap supplemental plan, it may cover some or all of that 20%.
If you’re on a Medicare Advantage plan, your out-of-pocket costs depend on your specific plan. Medicare Advantage plans must cover the same categories of equipment as Original Medicare, but they can set their own cost-sharing amounts and require you to use suppliers within their network. Check your plan’s Evidence of Coverage document or call the plan directly before starting the process.
Rental vs. Ownership
Medicare doesn’t buy most wheelchairs outright. Instead, it pays a monthly rental fee. After 13 continuous months of rental payments, the supplier is required to transfer ownership of the wheelchair to you at no additional cost. From that point on, you own the equipment.
During those 13 months, Medicare continues to cover the rental as long as medical necessity continues. If your condition improves and you no longer need the wheelchair before the 13 months are up, rental payments stop. Once you own the chair, Medicare may also cover reasonable repairs and maintenance.
If Your Claim Is Denied
Denials happen, and they’re not always final. The most common reasons are insufficient documentation or a determination that the equipment isn’t medically necessary based on what was submitted. If your claim is denied under Original Medicare, you can appeal through a formal process that starts with a redetermination request. If you’re on a Medicare Advantage plan, you appeal through the plan itself, which must provide an independent review of your case.
The best way to avoid a denial is to make sure your doctor’s notes are thorough from the start. Vague documentation like “patient has difficulty walking” won’t cut it. The notes need to specifically address why lesser mobility aids won’t work, what daily activities are impaired, and what your physical exam findings show. If your doctor isn’t familiar with Medicare’s documentation requirements for wheelchairs, bringing a printed copy of the criteria to your appointment can help.
