What Medicare Covers for Knee Scooters and Mobility Aids

Medicare's Coverage for Knee Scooters

Medicare Part B covers knee scooters, but only if your doctor prescribes one and it meets Medicare's definition of durable medical equipment (DME). A knee scooter is a wheeled device you kneel on to keep weight off an injured leg — Medicare treats it the same way it treats walkers, canes, and wheelchairs. You will pay 20% of the approved amount after you meet your Part B deductible; Medicare pays the other 80%.

The catch is that Medicare will not pay for a knee scooter you buy outright or rent on your own. Your doctor must write an order stating that you need it for a medical reason — a broken leg, severe ankle sprain, knee surgery recovery, or similar injury. The supplier you rent or buy from must be enrolled as a Medicare DME provider. If you use a non-enrolled supplier, Medicare will not reimburse you at all.

Knee scooters are usually rented rather than purchased through Medicare. A typical rental runs 28 to 30 days, and Medicare will cover multiple rental periods if your doctor continues to prescribe it. If you rent long enough, the total rental cost may reach the purchase price; at that point, Medicare switches you to a purchase instead, and you own the scooter.

Key Takeaways

• Your doctor must write a prescription for a knee scooter before Medicare will pay for it; you cannot buy one on your own and ask Medicare to reimburse you.
• You must rent or buy from a Medicare-enrolled DME supplier, or Medicare will not cover the cost.
• You pay 20% of the Medicare-approved amount after meeting your Part B deductible; Medicare pays 80%.
• Most people rent a knee scooter through Medicare for 28 to 30 days at a time, and can request additional rental periods if their doctor approves.
• If you rent for long enough that the total cost reaches the purchase price, Medicare will buy it for you instead.

How to Get a Knee Scooter Through Medicare

Start by talking to your doctor about whether a knee scooter is medically necessary for your condition. Your doctor does not have to write a formal prescription form — a note in your medical record stating that you need a knee scooter for your injury is enough. The note should say why you need it (for example, "non-weight-bearing status following ACL repair") and how long you will need it.

Once you have your doctor's order, contact a Medicare-enrolled DME supplier. You can find one by calling your Medicare plan or searching the Medicare DME supplier directory online. Tell the supplier you have a doctor's order for a knee scooter rental. The supplier will verify your Medicare coverage, confirm your deductible status, and calculate what you owe. They will then deliver the scooter to your home or a location you choose.

Keep your doctor's order and the supplier's paperwork. If you need the scooter for longer than the initial rental period, your doctor can write an extension order, and you can request another rental period from the same supplier or a different one.

What Medicare Considers Medically Necessary

Medicare will cover a knee scooter only if the reason you need it fits their definition of medical necessity. Common reasons Medicare approves include a broken leg or ankle, ACL or other knee surgery recovery, severe sprains, diabetic foot ulcers that require non-weight-bearing status, and post-surgical swelling that prevents walking. Your doctor's order should clearly state the medical reason.

Medicare is less likely to cover a knee scooter if you straightforward prefer it to crutches or if you want one "just in case." The device must be medically necessary for your specific condition right now. If your doctor believes it is necessary but Medicare's contractor denies the claim, your doctor can appeal the decision and provide additional medical documentation.

Renting Versus Buying a Knee Scooter

Most people rent a knee scooter through Medicare because the rental period is usually short — typically four to eight weeks while an injury heals. Renting costs less upfront and you do not have to store or maintain the equipment once you no longer need it. Medicare covers the rental in the same way it covers other DME rentals: you pay 20% of the approved rental amount after your deductible.

If you need the scooter for a longer time, the rental costs add up. Medicare has a rule called the rental-to-purchase threshold: once the total amount paid in rentals reaches the purchase price Medicare approves, the supplier must sell you the scooter instead of continuing to rent it. At that point, you own it and can keep it as long as you need it. You still pay 20% of the purchase price; Medicare pays 80%.

Some people choose to buy a knee scooter outright from a retail store instead of renting through Medicare. If you do this, you pay the full retail price yourself, and Medicare will not reimburse you. This route makes sense only if you want a specific brand or model that your Medicare supplier does not stock, or if you want to own it when ready without waiting for Medicare approval.

Your Out-of-Pocket Costs

Your cost depends on whether you have met your Part B deductible for the year. For 2024, the Part B deductible is $240 (this amount changes each year). Once you meet it, you pay 20% of the Medicare-approved rental or purchase price for the knee scooter.

The Medicare-approved amount varies by supplier and region, but a typical monthly knee scooter rental might be approved at $100 to $150. If the approved amount is $120 per month and you rent for one month, you would pay $24 (20% of $120) after your deductible is met. If you rent for three months, you would pay $72 total in coinsurance.

If you have a Medigap or Medicare Advantage plan, your out-of-pocket cost may be lower. Medigap plans often cover the 20% coinsurance, and Medicare Advantage plans have their own cost-sharing rules. Check your plan documents or call your plan to find out what you will owe.

What Happens if Medicare Denies Your Claim

If Medicare or your DME supplier tells you that a knee scooter is not covered, ask for the reason in writing. Common reasons for denial include: your doctor did not write an order, the supplier is not Medicare-enrolled, or Medicare's contractor decided the scooter was not medically necessary for your condition.

If you disagree with the denial, you have the right to appeal. Your doctor can help by submitting additional medical records or a letter explaining why the knee scooter is necessary. The appeal process takes time — usually 30 to 60 days — so if you need the scooter urgently, you may choose to rent it privately while the appeal is pending and then seek reimbursement if you win.

Contact your Medicare plan or the DME supplier's customer service line to start an appeal. They will tell you what documents to submit and where to send them. Keep copies of everything you send.

Alternatives to a Knee Scooter

If Medicare denies coverage for a knee scooter or you cannot wait for approval, other mobility aids may be covered instead. Crutches, walkers, and canes are all covered by Medicare Part B under the same DME rules. A wheelchair or rollator (a walker with wheels and a seat) may also be an option depending on your condition.

Your doctor can prescribe any of these alternatives, and you would follow the same process: use a Medicare-enrolled DME supplier and pay 20% of the approved amount after your deductible. Some people find crutches difficult to use if they have balance problems, arthritis, or upper-body weakness; in those cases, a knee scooter or wheelchair may be more practical even if it takes longer to arrange.

Frequently Asked Questions

Do I need a prescription from my doctor to get a knee scooter?

Yes. Your doctor must document in your medical record that you need a knee scooter for a medical reason. This does not have to be a formal prescription pad — a note from your doctor saying you need non-weight-bearing mobility aids is enough. Without this documentation, Medicare will not pay.

Can I buy a knee scooter online and have Medicare reimburse me?

No. Medicare will only pay if you rent or buy from a Medicare-enrolled DME supplier. If you purchase from a retail store or online retailer that is not enrolled with Medicare, you pay the full cost yourself and cannot get reimbursed.

How long can I rent a knee scooter through Medicare?

There is no set limit. Your doctor can write extension orders, and you can request additional rental periods as long as the scooter remains medically necessary. If the total rental cost reaches the purchase price Medicare approves, Medicare will buy it for you instead of continuing to rent.

What if I have a Medicare Advantage plan instead of Original Medicare?

Medicare Advantage plans must cover knee scooters under the same rules as Original Medicare, but your out-of-pocket cost may be different. Call your plan to ask what you will owe for a knee scooter rental or purchase. Some Advantage plans have copays instead of coinsurance, or may cover the full cost with no patient payment.

Will my Medigap plan cover the 20% coinsurance for a knee scooter?

Most Medigap plans cover Part B coinsurance, which means they would pay the 20% you owe for a knee scooter. Check your Medigap plan documents or call your plan to confirm. If your plan covers coinsurance, you may owe nothing out of pocket once your Part B deductible is met.
