Medicare Part B covers orthotics, but only specific types and only when you follow the right steps. The term “orthotics” means different things to different people, and Medicare draws sharp lines between what qualifies and what doesn’t. Understanding those distinctions is the difference between a covered claim and an out-of-pocket expense.
What Medicare Considers an “Orthotic”
Medicare defines orthotics narrowly: they are braces for the leg, arm, back, or neck. By law, Medicare cannot pay for an orthosis that falls outside those four categories. The device must be rigid or semi-rigid and serve one of two purposes: supporting a weak or deformed body part, or restricting movement in an injured or diseased area. A soft elastic knee sleeve, for instance, typically won’t qualify. A hinged knee brace prescribed after ligament surgery likely will.
This definition matters because many people searching for “orthotics” are actually looking for custom shoe inserts or foot orthotics. Medicare does not cover custom shoe inserts for most people. The major exception is if you have diabetes with serious foot complications, which has its own separate benefit with its own rules (covered below).
The Three Requirements for Coverage
Every covered orthotic must meet three conditions. Miss any one of them and Medicare will deny the claim.
- Medical necessity. A doctor or qualified health care provider must determine that the brace is medically necessary for your specific condition. “Medically necessary” means the device treats or manages a diagnosed problem, not that it would be nice to have for comfort or prevention.
- A face-to-face encounter. Federal rules require an in-person visit with the ordering practitioner before certain orthotics can be delivered. During this visit, your provider documents why you need the device and writes a formal order. This written order must exist before the brace is delivered to you.
- An enrolled Medicare supplier. The company or provider who furnishes the brace must be enrolled in Medicare as a durable medical equipment (DME) supplier. If you get a brace from a supplier that isn’t enrolled, Medicare won’t pay anything.
How the Documentation Process Works
Documentation is where most claims succeed or fail. Your treating physician needs to record in your medical chart exactly why you need the orthotic. For custom-fabricated devices (made from a mold or scan of your body rather than pulled off a shelf), the documentation bar is higher. Your doctor’s records must explain why a custom device is necessary rather than a prefabricated one, and the orthotist who builds the device keeps a separate functional evaluation on file.
None of this paperwork typically falls on you directly. Your doctor writes the order, the supplier handles the claim coding, and Medicare processes the payment. But you can protect yourself by confirming two things before you receive the device: that your doctor has completed the written order, and that your supplier is Medicare-enrolled. Ask the supplier directly whether they “accept assignment,” which is the term for agreeing to bill Medicare at the approved rate.
What You’ll Pay Out of Pocket
Once Medicare approves an orthotic, you pay 20% of the Medicare-approved amount. You also need to have met your annual Part B deductible first, which is $257 in 2025 and rises to $283 in 2026. So if Medicare approves a back brace at $500 and you’ve already met your deductible, your cost is $100.
This math changes if your supplier doesn’t accept assignment. A participating supplier is required to charge you only the 20% coinsurance plus any remaining deductible. A non-participating supplier can charge more than the Medicare-approved amount, leaving you with a larger bill. Always confirm assignment before you agree to receive the device. If you have a Medigap (supplement) plan, it may cover part or all of that 20% coinsurance depending on your policy.
Medicare Advantage Plans
If you’re enrolled in a Medicare Advantage plan (Part C) rather than Original Medicare, your plan must cover everything Original Medicare covers, including orthotics. However, your plan can require prior authorization before approving the device, and it may limit you to in-network suppliers. Call the number on your plan’s member card before scheduling anything. Ask whether the specific device needs prior authorization and whether the supplier is in your plan’s network. Going out of network or skipping prior authorization can result in a denial even when the device itself would otherwise be covered.
Diabetic Therapeutic Shoes and Inserts
Custom foot orthotics and shoe inserts are excluded from Medicare’s general orthotic benefit. The exception is a separate benefit for people with diabetes who have severe foot problems. If you qualify, Medicare covers one pair of custom-molded shoes with inserts, or one pair of extra-depth shoes, per calendar year. You can also get additional pairs of inserts: two extra pairs per year with custom-molded shoes, or three extra pairs per year with extra-depth shoes.
Qualifying requires all of the following:
- A diabetes diagnosis.
- At least one serious foot condition documented in your medical record: a previous amputation of part of either foot, a history of foot ulcers, pre-ulcerative calluses, peripheral neuropathy with callus formation, foot deformity, or poor circulation in either foot.
- Certification from the physician managing your diabetes. This doctor must confirm in writing that you meet the criteria and that therapeutic footwear is part of a comprehensive diabetes care plan.
Timing matters. The certifying physician must have seen you in person within six months before the shoes or inserts are delivered, and the certification statement must be signed after that visit and no more than three months before delivery. If the foot condition was documented by a podiatrist or another provider rather than your diabetes doctor, the certifying physician can reference those records but must initial and date them to confirm agreement.
Replacements and Repairs
Medicare covers adjustments to braces when they’re needed because of normal wear or a change in your condition, as long as a physician orders the adjustment. If your brace is lost, stolen, irreparably damaged, or has exceeded its reasonable useful lifetime, Medicare will cover a replacement. The standard useful lifetime for DME is generally five years from the date you started using it. You typically cannot get a new version of the same brace before that five-year mark unless one of those exceptions applies.
Diabetic shoes and inserts follow a different schedule. Because the benefit resets each calendar year, you’re eligible for a new pair of shoes and new inserts annually, provided you still meet all the qualifying criteria and your physician recertifies your need.
What to Do If a Claim Is Denied
If Medicare denies your orthotic claim, the denial letter (called a Medicare Summary Notice) will include the reason. Common reasons include missing documentation, no written order prior to delivery, or a determination that the device wasn’t medically necessary. You have the right to appeal, and the first level is a redetermination request, which must be filed within 120 days of receiving the notice.
Before a supplier provides a device they expect Medicare to deny, they’re required to give you an Advance Beneficiary Notice (ABN). This form tells you ahead of time that Medicare may not pay and gives you the choice to proceed at your own expense or decline the item. If you never received an ABN and the claim is denied, you generally cannot be held responsible for the cost. Knowing this gives you leverage if billing disputes arise.
