Medicare covers some orthotics, but not all — and the rules depend on whether you have Original Medicare or a Medicare Advantage plan

Orthotics are custom-made or prefabricated devices that support or correct the function of your limbs or spine — things like shoe inserts for flat feet, knee braces, ankle supports, or back braces. Original Medicare (Part B) covers orthotics only when a doctor orders them for a specific medical condition and they meet Medicare's definition of "durable medical equipment" or DME. Medicare Advantage plans (Part C) may cover different items or have different rules, so you need to check your plan's coverage document.

The catch is that Medicare does not cover all orthotics equally. A custom orthotic prescribed by your doctor has a better chance of being covered than an over-the-counter brace you buy yourself. And some orthotics — like compression socks or shoe inserts for general foot pain — are rarely covered no matter who prescribes them.

Key Takeaways

  • Original Medicare Part B covers orthotics classified as durable medical equipment when prescribed by a doctor for a medical condition, but you typically pay 20 percent of the approved amount after your deductible.
  • Your doctor must document that the orthotic is medically necessary and that you cannot function without it — general comfort or prevention alone is not enough for coverage.
  • Medicare Advantage plans set their own coverage rules for orthotics, so you must check your specific plan's formulary or call the plan to learn what is covered.
  • You will need a written prescription from your doctor and must use a Medicare-approved supplier to have the best chance of coverage being processed without delay.
  • Some orthotics — like compression socks, shoe inserts for bunions, or braces for arthritis prevention — are typically not covered even with a prescription.

What Original Medicare Part B covers

Original Medicare Part B covers orthotics when they meet three conditions: a doctor must prescribe them, they must be medically necessary for a diagnosed condition, and they must be classified as durable medical equipment. In practice, this means the orthotic has to help you function or reduce pain from a condition that significantly limits your movement or activity.

Common orthotics that may be covered include custom foot orthotics for severe flat feet or diabetic neuropathy, knee braces for arthritis or ligament damage, ankle-foot orthotics (AFOs) for stroke recovery or nerve damage, and spinal orthotics for vertebral compression fractures or post-surgical support. The key word is "custom" — devices made specifically for your body are more likely to be covered than off-the-shelf braces.

If Medicare approves your orthotic, you pay 20 percent of the Medicare-approved amount after you have met your Part B deductible. The supplier bills Medicare directly, and Medicare sends you an explanation of benefits showing what they paid and what you owe.

How to get coverage through Original Medicare

Start by talking to your doctor about your condition and whether an orthotic might help. Your doctor does not have to be an orthopedist or specialist — your primary care doctor can prescribe one. The doctor will write a prescription that describes the orthotic, the reason you need it, and how long you will use it.

Next, find a Medicare-approved supplier. You can search for one at the DMEPOS Supplier Directory on the Centers for Medicare & Medicaid Services (CMS) website, or ask your doctor's office for a referral. Using an approved supplier matters because they know Medicare's rules and can submit your claim correctly the first time.

Bring your prescription and insurance card to the supplier. They will take measurements or molds if needed, create or fit the orthotic, and submit the claim to Medicare on your behalf. Medicare will review the prescription and your medical records to decide whether to cover it. This review can take one to three weeks.

If Medicare denies the claim, the supplier will send you a notice explaining why. You can ask your doctor to provide more medical documentation, or you can file an appeal. Many denials are overturned on appeal if your doctor can show the orthotic is truly medically necessary.

Medicare Advantage plan coverage

Medicare Advantage plans (Part C) are required to cover at least what Original Medicare covers, but many plans cover more. Some plans cover over-the-counter orthotics or compression socks that Original Medicare does not. Others have lower out-of-pocket costs for orthotics or do not require a deductible.

The problem is that each plan writes its own rules. You need to check your plan's coverage document — usually called the "formulary" or "benefits guide" — or call your plan's customer service line to ask specifically about the orthotic you need. When you call, have your doctor's diagnosis ready and describe the orthotic as clearly as you can.

Some Medicare Advantage plans also require prior authorization, meaning the plan must approve the orthotic before you get it. If your plan requires this, your doctor's office or the supplier will submit the request, and the plan will respond within a few business days.

Orthotics Medicare typically does not cover

Medicare rarely covers orthotics prescribed for prevention or general comfort. Compression socks for circulation, shoe inserts for mild bunions, or braces to prevent arthritis are examples. Medicare's standard is that the orthotic must treat an existing condition that significantly limits your function — not prevent a future problem or provide comfort alone.

Orthotics for cosmetic reasons are never covered. If you want a brace or insert mainly because you prefer how it looks or feels, Medicare will not pay for it. Similarly, orthotics for sports performance or athletic training are not covered, even if a doctor prescribes them.

Some conditions fall into a gray area. Orthotics for mild arthritis, chronic pain without nerve damage, or balance problems may or may not be covered depending on how severe your condition is and how well your doctor documents that you cannot function without the device. Your doctor's documentation is everything in these cases.

What you pay out of pocket

With Original Medicare, you pay 20 percent of the Medicare-approved amount after you have met your Part B deductible (which is $240 in 2024, though this amount changes yearly). If the approved amount is $500, you would pay $100 after your deductible is met. If you have not met your deductible yet, you pay the full amount until you do.

The actual cost to you depends on what the supplier charges and what Medicare approves. Medicare approves a set amount for each type of orthotic, and the supplier cannot charge you more than that approved amount. If the supplier's price is higher, they must write off the difference.

With Medicare Advantage, your out-of-pocket cost depends on your plan. Some plans charge a copay (a flat fee like $50), others charge coinsurance (a percentage like 20 percent), and some cover orthotics with no additional cost beyond your monthly premium. Check your plan documents or call to find out.

What to ask your doctor

Before your appointment, write down your symptoms and how they affect your daily life — this helps your doctor understand why the orthotic is medically necessary. At your visit, ask these questions:

  • Do you think an orthotic would help my condition, and if so, what type?
  • Will you write a prescription for it, and will you include details about why it is medically necessary?
  • Do you have a preferred supplier, or should I find one on the Medicare DMEPOS directory?
  • If Medicare denies the claim, will you provide additional documentation to support an appeal?

Your doctor's willingness to document the medical necessity and support an appeal if needed makes a real difference in whether you get coverage.

When to contact Medicare or your plan

Contact Original Medicare (1-800-MEDICARE) if a supplier tells you that Medicare will not cover an orthotic and you believe it should, or if you receive a denial notice and want to understand the reason. You can also ask Medicare whether a specific orthotic is typically covered for your condition before you get it.

Contact your Medicare Advantage plan if you are unsure whether an orthotic is covered under your plan, or if you need prior authorization. Call the number on your insurance card. Have your doctor's diagnosis and the name of the orthotic ready when you call.

If you receive a denial and disagree with it, you have the right to appeal. Original Medicare appeals go through a formal process with multiple levels; your denial notice will explain how to start. Medicare Advantage appeals follow your plan's process, which is also described in your denial notice.

Frequently Asked Questions

Can I buy an orthotic over the counter and have Medicare reimburse me?

Not usually. Medicare requires a doctor's prescription and typically covers only custom orthotics made by a Medicare-approved supplier. If you buy an off-the-shelf brace on your own, Medicare will not reimburse you. The exception is if your Medicare Advantage plan specifically covers over-the-counter orthotics — check your plan first.

Does Medicare cover replacement orthotics if mine wears out?

Yes, but only after a certain amount of time. Medicare typically covers a replacement orthotic after five years of use, or sooner if your condition changes significantly and your doctor prescribes a new one. The supplier can tell you when you become may be able to access for a replacement.

What if my doctor says I need an orthotic but Medicare denies it?

Ask your doctor to submit additional medical records or a letter explaining why the orthotic is medically necessary for your specific condition. Then file an appeal with Medicare or your plan using the instructions on the denial notice. Many denials are overturned when doctors provide more detail about how the orthotic will improve your function.

Do I need prior authorization before getting an orthotic?

Original Medicare does not require prior authorization for most orthotics, but some Medicare Advantage plans do. Check your plan's rules or call your plan to ask. If prior authorization is required, your doctor's office or the supplier will submit the request before you get the orthotic.

Can I choose any supplier, or does it have to be Medicare-approved?

You can choose any supplier, but using a Medicare-approved supplier gives you the best chance of smooth coverage. Approved suppliers know Medicare's rules and submit claims correctly. If you use a non-approved supplier, you may have to pay upfront and file for reimbursement yourself, which is slower and riskier.
