Medicare covers prosthetic limbs, but only through Part B and only when a doctor prescribes one as medically necessary after amputation or severe limb loss

Medicare Part B pays for prosthetic arms, legs, hands, and feet when you have lost a limb or have a severe condition that makes a natural limb unusable. The prosthetic must be prescribed by your doctor and fit into one of Medicare's covered categories. Medicare does not cover cosmetic prosthetics, prosthetics for people born without a limb, or devices that straightforward improve comfort without restoring basic function.

You will pay 20% of the approved cost after you meet your Part B deductible. The supplier must be enrolled with Medicare — not all prosthetic companies are. The process typically takes several weeks from prescription to fitting, so planning ahead matters if you know an amputation is coming.

Key Takeaways

  • Medicare Part B covers prosthetic limbs prescribed by a doctor after amputation or severe limb loss, and you pay 20% of the approved amount after your deductible.
  • The prosthetic supplier must be enrolled with Medicare, and you should check their status before starting the fitting process.
  • Medicare covers the prosthetic itself, basic repairs, and replacements every five years, but not custom cosmetic features or routine maintenance like socks and liners.
  • Your doctor must document that the prosthetic is medically necessary and that you are physically and mentally able to use it safely.
  • If Medicare denies your claim, you can file an appeal, and your supplier can help you gather the medical records needed to support it.

What Medicare Part B actually covers for prosthetics

Medicare covers the prosthetic limb itself — the artificial arm, leg, hand, or foot — along with the socket that attaches it to your body. It also covers the initial fitting and adjustments needed in the first few months after you receive the prosthetic. If your prosthetic breaks or wears out, Medicare covers repairs.

Every five years, Medicare will cover a replacement prosthetic if your medical condition or body size has changed enough to require a new one. Your doctor must document that the replacement is necessary, not just that you want an upgrade. Medicare also covers certain add-ons that restore basic function — for example, a motorized knee joint or a hand with multiple grip positions — if your doctor prescribes them as medically necessary.

What Medicare does not cover includes routine maintenance items like replacement socks or liners (the soft material between your skin and the prosthetic), cosmetic upgrades like custom paint or realistic skin tones, or prosthetics prescribed purely for comfort rather than function. Some suppliers bundle these items into their fees, so ask upfront what is included in the Medicare-covered price and what you would pay out of pocket.

Who qualifies and what your doctor needs to document

You may have access to if you have lost a limb due to amputation, diabetes, vascular disease, trauma, or cancer, or if you have a severe condition that makes your natural limb unusable — for example, severe arthritis or nerve damage that prevents you from controlling it. You do not may have access to if you were born without a limb, even if you have never had a prosthetic before.

Your doctor must write an order stating that the prosthetic is medically necessary for you to perform basic daily activities. The doctor also needs to confirm that you are physically and mentally able to use the prosthetic safely — for example, that you have enough balance, strength, and cognitive ability to walk with a prosthetic leg without falling. If you have severe dementia or are bedbound, Medicare may deny the claim because the prosthetic would not be safe or practical for you to use.

The doctor's order should specify which type of prosthetic you need and any special features required by your condition. If you use a wheelchair and do not walk, Medicare will likely deny coverage for a prosthetic leg because you cannot use it. Be honest with your doctor about your daily activities and your goals — this information goes into the medical record and affects whether Medicare will cover the device.

How to find a Medicare-enrolled prosthetic supplier

Not every prosthetic company is enrolled with Medicare. If you use a supplier who is not enrolled, Medicare will not pay, and you will owe the full cost. Before you schedule a fitting, ask the supplier directly: "Are you enrolled with Medicare?" or "Can you bill Medicare for prosthetics?" You can also search the Medicare provider directory at Medicare.gov under "Suppliers" and filter for prosthetic and orthotic suppliers in your area.

Once you have found an enrolled supplier, give them your Medicare card and your doctor's prescription. The supplier will submit the prescription to Medicare for approval before they order or fit the prosthetic. This step is important because it gives Medicare a chance to review whether the prosthetic meets coverage rules before you incur the cost. If Medicare denies it at this stage, you will know before spending money on fitting appointments.

If you live in a rural area or cannot find an enrolled supplier nearby, ask your doctor for a referral or contact your state's vocational rehabilitation agency — they sometimes have contracts with suppliers and can help you find one. Some suppliers will travel to your home for fitting if you cannot travel to them.

What you pay and how the billing works

You pay 20% of Medicare's approved amount for the prosthetic after you have met your Part B deductible for the year. The approved amount is set by Medicare, not by the supplier's list price. A prosthetic leg might have a list price of $15,000, but Medicare's approved amount might be $8,000 — you would pay 20% of $8,000, or $1,600, plus any remaining deductible.

The supplier bills Medicare directly. Medicare pays its 80% share to the supplier, and the supplier bills you for your 20% share. You should receive an Explanation of Benefits (EOB) from Medicare showing what was approved, what Medicare paid, and what you owe. Keep this document — you will need it if you file an appeal or if you have questions about the bill.

If the supplier charges you more than your 20% share, that is illegal. Medicare-enrolled suppliers are required to accept Medicare's approved amount as payment in full for the prosthetic itself. If a supplier tries to bill you extra, contact Medicare at 1-800-MEDICARE to report it.

Repairs, replacements, and when Medicare will cover them again

Medicare covers repairs to your prosthetic if it breaks or stops working properly. The supplier can bill Medicare for the repair, and you pay 20% of the approved repair cost. Routine maintenance — cleaning, adjusting the fit, replacing worn liners — is usually covered as part of the initial fitting and adjustment period, but after that, some maintenance costs may fall to you.

Medicare will cover a replacement prosthetic five years after your current one was fitted, or sooner if your medical condition has changed significantly. For example, if you gain or lose a large amount of weight, your prosthetic socket may no longer fit properly, and Medicare may cover a new one before five years have passed. Your doctor must document the change and explain why a new prosthetic is necessary.

If your prosthetic is damaged beyond repair — for example, if you are in an accident — Medicare may cover a replacement sooner than five years. The supplier and your doctor will need to document that repair is not possible and that a new prosthetic is medically necessary. This is not automatic, so ask your supplier about the appeal process if you need an early replacement.

What to do if Medicare denies your claim

If Medicare denies your prosthetic claim, you will receive a notice explaining the reason. Common reasons include: the supplier was not enrolled with Medicare, your doctor did not document medical necessity clearly enough, or Medicare determined you cannot safely use the prosthetic. You have the right to appeal.

Start by asking your supplier and doctor to review the denial together. Often, the issue is that the doctor's order did not include enough detail about why the prosthetic is medically necessary or how you will use it. Your doctor can write a more detailed letter explaining your condition, your functional goals, and why the prosthetic is essential. The supplier can then resubmit the claim with this additional documentation.

If the resubmission is denied, you can file a formal appeal with Medicare. The process has several levels: reconsideration, hearing before an administrative law judge, and further appeal. Your supplier may help you gather medical records and write the appeal, though they are not required to. You can also contact your State Health Insurance information Program (SHIP) — it is free and can help you understand your appeal rights.

Frequently Asked Questions

Does Medicare cover prosthetics for people born without a limb?

No. Medicare only covers prosthetics for people who have lost a limb through amputation or have a severe condition that makes a natural limb unusable. If you were born without a limb, Medicare does not cover a prosthetic, even if you have never had one before. You may be able to find coverage through Medicaid, private insurance, or nonprofit organizations that provide prosthetics.

Will Medicare pay for a prosthetic before I have the amputation?

No. Medicare requires that you have already lost the limb or have a documented condition that makes it unusable. If your doctor knows an amputation is coming, you can discuss prosthetic options and get a prescription ready, but Medicare will not pay until after the amputation has occurred and you have healed enough to be fitted.

What if I want a prosthetic with special features like a waterproof foot or a microprocessor knee?

Medicare covers prosthetics with advanced features if your doctor prescribes them as medically necessary for your specific condition and activity level. A microprocessor knee, for example, may be covered if you are an active walker and your doctor documents that it reduces your fall risk. You will still pay 20% of the approved cost. Ask your supplier which advanced features are covered and which are considered upgrades you would pay for out of pocket.

How long does it take from prescription to getting my prosthetic?

The timeline varies, but typically expect four to eight weeks. This includes time for Medicare approval (usually one to two weeks), the supplier ordering the components (one to two weeks), your fitting appointments (one to two weeks), and adjustments after you start wearing it (ongoing). If you need the prosthetic urgently, tell your doctor and supplier — they may be able to expedite some steps.

Can I use my Medigap or Medicare Advantage plan instead of Part B?

Medicare Advantage plans must cover at least what Original Medicare Part B covers, so your prosthetic should be covered. However, your out-of-pocket costs, deductibles, and supplier networks may differ from Part B. Check your plan's coverage details or call the plan before you start the fitting process. Medigap plans supplement Part B but do not replace it, so Part B is still your primary coverage.
