Medicare's Coverage of Knee Scooters

Medicare Part B covers knee scooters, but only if your doctor prescribes one and it meets specific conditions. The scooter must be deemed medically necessary — meaning your doctor has documented that you cannot walk safely or bear weight on one leg due to injury, surgery, or illness. Medicare will not cover a knee scooter you buy on your own or one prescribed without proper medical justification.

Coverage works through Durable Medical Equipment (DME) suppliers that contract with Medicare. You cannot order directly from a retail store and expect reimbursement. Your doctor must write an order, you must use an approved DME supplier, and Medicare pays 80 percent of the approved amount after you meet your Part B deductible. You pay the remaining 20 percent.

The approval process typically takes one to two weeks. Your DME supplier submits the prescription and medical documentation to Medicare for review. During this time, some suppliers will loan you equipment at no cost so you are not immobilized while waiting. Ask about this when you contact them.

Key Takeaways

  • Your doctor must prescribe the knee scooter and document that it is medically necessary for your condition.
  • You must rent or purchase through a Medicare-approved Durable Medical Equipment supplier, not a retail store.
  • Medicare pays 80 percent of the approved amount after your Part B deductible is met; you pay 20 percent.
  • The approval process usually takes one to two weeks, and some suppliers offer loaner equipment while you wait.
  • If Medicare denies coverage, you can request a reconsideration within 180 days of the denial letter.

How to Start the Process With Your Doctor

Begin by scheduling an appointment with the doctor treating your leg injury or condition. Bring documentation of your diagnosis — recent imaging, surgical reports, or clinical notes. The doctor needs to see evidence that weight-bearing on the affected leg is unsafe or impossible.

During the visit, tell your doctor you want to use a knee scooter and ask whether they believe it is medically necessary. If they agree, ask them to write a written order (sometimes called a prescription or DME order) that includes your diagnosis, the reason the scooter is needed, and how long you will need it. The order should specify "knee scooter" or "knee walker" by name.

Some doctors' offices have relationships with specific DME suppliers and may hand you a referral. Others will give you the order and leave the supplier choice to you. Either way, keep a copy of the order for your records.

Finding and Working With a Medicare-Approved DME Supplier

Not every medical supply store is a Medicare-approved DME supplier. You can search for approved suppliers in your area using the Medicare DME Supplier Locator on Medicare.gov, or call 1-800-MEDICARE to ask for a list. When you call a supplier, have your doctor's order ready and ask three things: whether they accept Medicare assignment, how long approval takes, and whether they offer loaner equipment while you wait.

"Medicare assignment" means the supplier agrees to accept Medicare's approved amount as payment in full for their services. This protects you from surprise bills. Some suppliers do not accept assignment, which means you could owe more than the 20 percent coinsurance.

Once you choose a supplier, give them your doctor's order, your Medicare card, and any other medical records they request. They will submit everything to Medicare for review. Ask for a timeline and a contact person you can follow up with if you do not hear back within the expected window.

What Happens if Medicare Denies Coverage

Medicare may deny coverage if your doctor's order lacks sufficient medical documentation, if the scooter is deemed not medically necessary, or if your condition does not meet Medicare's criteria. The denial will come in a letter that explains the reason and your next steps.

You have the right to request a reconsideration within 180 days of the denial date. To do this, write to the address listed in the denial letter and include new medical evidence if you have it — for example, a more detailed letter from your doctor explaining why the scooter is essential, or additional test results showing the severity of your condition.

If reconsideration is denied, you can request a hearing before an administrative law judge. This process is free and does not require a lawyer, though some people choose to have one. The Medicare.gov website has instructions for each appeal level.

Renting Versus Purchasing Through Medicare

Medicare covers both rental and purchase of knee scooters, but the rules differ. For rental, Medicare typically covers up to the point where cumulative payments equal the purchase price of the item. After that, the scooter becomes yours and Medicare stops paying. Most knee scooters reach this threshold after three to six months of rental.

If you purchase outright, Medicare pays 80 percent of the approved amount in a single payment (after your deductible). If you rent, Medicare pays 80 percent of the monthly rental fee each month until the total paid equals the purchase price.

Ask your DME supplier which option costs less for your situation. Sometimes renting is cheaper if you only need the scooter for a few weeks. Sometimes purchasing makes sense if you will need it for months. The supplier can show you both costs before you decide.

Medicare Advantage Plans and Knee Scooter Coverage

If you have a Medicare Advantage plan (Part C) instead of Original Medicare, your coverage for knee scooters may differ. Some Advantage plans cover DME the same way Original Medicare does. Others have different rules, higher copays, or require prior authorization from the plan before your doctor writes the order.

Call your Advantage plan's customer service number (on your insurance card) and ask specifically about knee scooter coverage. Ask whether you need prior authorization, which DME suppliers are in-network, and what your out-of-pocket cost will be. Get the answer in writing if possible, so you have it for your records.

If your Advantage plan denies coverage that Original Medicare would cover, you can file a complaint with your state's insurance commissioner or with Medicare directly.

Frequently Asked Questions

Does Medicare cover knee scooters for arthritis or chronic knee pain?

Medicare covers knee scooters only when weight-bearing on the leg is unsafe or impossible due to acute injury, surgery, or acute illness. Chronic arthritis or pain alone is usually not enough. Your doctor must document that the scooter is medically necessary for your specific condition, not just helpful for comfort.

What if I already bought a knee scooter before getting a prescription?

Medicare will not reimburse you for a scooter you purchased without a prior prescription and approval. Going forward, get your doctor's order and work with a Medicare-approved supplier before you buy. If you have already spent money, ask your doctor whether they would have prescribed one — if so, you can still submit a claim with the receipt and prescription, though approval is not may provide.

How much will I pay out of pocket?

You pay 20 percent of Medicare's approved amount after you meet your Part B deductible for the year. The exact cost depends on the scooter model and your deductible status. Your DME supplier can tell you the approved amount and calculate your 20 percent share before you commit.

Can I use my Supplemental Insurance to cover the 20 percent?

Many Medigap (Supplemental Insurance) plans cover the 20 percent coinsurance for DME, including knee scooters. Check your plan documents or call your Medigap insurer to confirm. If you have coverage, tell your DME supplier so they can bill both Medicare and your supplement in the correct order.

What if my condition improves and I no longer need the scooter?

If you are renting, you can return it and stop paying. If you purchased it, you own it and can keep it, donate it, or sell it. Medicare does not require you to return purchased equipment. If you rented and want to stop early, contact your supplier about their return policy — some allow early returns without penalty.
