Ask whether Medicare covers "orthotics" and you will get a frustrating answer: it depends entirely on what you mean. A rigid leg brace prescribed after surgery is covered. A pair of custom shoe inserts from a podiatrist usually is not — unless you have diabetes and meet a specific set of conditions, in which case it is. The confusion is not accidental. These items sit in separate benefit categories written into Medicare law decades apart, and each category has its own rules about what qualifies and who can supply it. Here is how the pieces fit together in 2026.
The Three Categories
Prosthetic devices. This category covers devices that replace all or part of an internal body organ or function — items such as cardiac pacemakers, cochlear implants, breast prostheses after a mastectomy, ostomy supplies, and prosthetic eyes. It also covers enteral and parenteral nutrition in certain circumstances.
Artificial limbs and braces. Medicare law specifically covers artificial legs, arms, and eyes, and leg, arm, back, and neck braces, including replacements needed because of a change in your physical condition. This is the category that covers rigid and semi-rigid bracing — ankle-foot orthoses, knee-ankle-foot orthoses, back braces, and cervical collars.
Therapeutic shoes and inserts for diabetes. This is its own benefit, separate from the two above, with its own eligibility and quantity rules described further below.
The practical significance: a device that fits one of these categories may be covered even if it would not meet the definition of durable medical equipment. A device that fits none of them is generally not covered, no matter how helpful it might be.
What Is Generally Covered
- Artificial limbs — including the prosthesis itself, sockets, liners, and components, plus repairs and replacement when medically necessary
- Braces for the leg, arm, back, and neck — when rigid or semi-rigid and used to support a weak or deformed body part or restrict motion
- Prosthetic eyes and, in certain circumstances, related supplies
- Breast prostheses and post-mastectomy bras following a covered mastectomy
- Ostomy supplies for people with a colostomy, ileostomy, or urinary ostomy
- Cardiac pacemakers, cochlear implants, and similar implanted devices, generally billed with the surgery that places them
What Is Generally Not Covered
- Over-the-counter arch supports and shoe inserts bought without a prescription
- Most custom foot orthotics for conditions such as plantar fasciitis, when not part of a leg brace and not tied to diabetes
- Orthopedic or corrective shoes on their own — with the diabetes exception below, and a narrow exception when the shoe is an integral part of a leg brace
- Elastic supports, compression sleeves, and soft garments that do not meet the definition of a brace
- Cosmetic replacements beyond what is medically necessary
Coverage of a specific item can also depend on local coverage determinations issued by the contractor that processes claims in your region, which is why two people in different states occasionally get different answers on borderline items.
Therapeutic Shoes for Diabetes
This benefit has narrow eligibility and precise limits. Medicare may cover therapeutic shoes and inserts if you have diabetes and at least one additional qualifying foot condition — such as a history of partial or complete foot amputation, a past foot ulcer, calluses that could lead to ulcers, nerve damage with evidence of callus formation, poor circulation, or foot deformity.
Per calendar year, Part B covers:
- One pair of custom-molded shoes and inserts, or one pair of extra-depth shoes
- Three pairs of inserts for extra-depth shoes, or two additional pairs for custom-molded shoes
- Shoe modifications may be substituted for inserts in some cases
Three separate people must be involved, and skipping any of them causes a denial:
- The doctor treating your diabetes must certify that you need therapeutic footwear
- A podiatrist or other qualified doctor must prescribe the shoes and inserts
- A qualified supplier — a podiatrist, orthotist, prosthetist, or pedorthist — must furnish and fit them
Our guide to podiatry and foot care coverage covers the related question of which foot exams and treatments Medicare pays for.
What You Pay in 2026
Under Original Medicare, these items follow standard Part B cost sharing:
- $283 annual Part B deductible
- 20% coinsurance of the Medicare-approved amount after the deductible
- No annual out-of-pocket limit under Original Medicare — a Medigap policy may cover the 20%, depending on the plan letter
For higher-cost items like a prosthetic limb, that 20% can be substantial, which is one reason people compare supplemental coverage options carefully.
Suppliers must be enrolled in Medicare. If a supplier is not enrolled, Medicare will not pay the claim. Suppliers who accept assignment may bill you only the deductible and coinsurance; those who do not may charge more. Ask before the device is ordered, and look up enrolled suppliers at medicare.gov/medical-equipment-suppliers.
In a Medicare Advantage plan, the plan must cover everything Original Medicare covers, but sets its own cost sharing, uses a provider and supplier network, and may require prior authorization. Those costs count toward the plan's out-of-pocket maximum — no more than $9,250 in-network in 2026. See our guide to prior authorization for how those reviews work.
Repairs, Replacement, and Documentation
- Repairs to a device you own are generally covered when the device still meets your medical need
- Replacement may be covered when an item is lost, stolen, irreparably damaged, or when your physical condition changes enough that the existing device no longer works
- Documentation drives outcomes. Denials in this category usually come down to a missing certification, an order that does not describe the medical need in the required detail, or a supplier enrollment problem
If a claim is denied, ask the prescriber and supplier to review the documentation first — many denials resolve without a formal appeal. If it stands, our guide to appealing a Medicare decision explains the levels and deadlines.

Summary and Next Steps
- Medicare covers prosthetic devices, artificial limbs and leg/arm/back/neck braces, and therapeutic shoes for diabetes under three separate benefit categories
- Over-the-counter inserts and most custom foot orthotics are generally not covered outside the diabetes benefit
- The diabetes footwear benefit covers one pair of shoes and a set number of inserts per calendar year, and requires certification, a prescription, and a qualified supplier
- You pay the $283 deductible and 20% coinsurance in 2026 under Original Medicare; Medigap may cover the 20%
- Use a Medicare-enrolled supplier and ask whether they accept assignment before ordering
- Repairs and replacements may be covered when medically necessary
Before a device is ordered, ask the supplier two questions: which benefit category does this fall under, and what documentation do you have on file? Those two answers predict most coverage outcomes in this category.
