For many people managing a knee condition, the cost of a brace is a genuine concern, and the natural question is whether Medicare will help. The short answer is that Medicare frequently does cover knee braces, including custom options, when they are medically necessary and the right conditions are met. The longer answer involves understanding how the coverage works, what documentation is required, and an important policy change that took effect in 2026. Coverage rules are detailed and can change, so treat what follows as an orientation rather than a guarantee, and confirm specifics with your supplier and Medicare.
The Basics: Braces as Durable Medical Equipment
Knee braces are classified as orthotics, a form of durable medical equipment (DME), and are covered under Medicare Part B’s braces benefit. To qualify, a brace must be a rigid or semi-rigid device used to support a weakened body part or to restrict motion in an injured or diseased area, and it must be deemed medically necessary. As DME, a covered brace is also expected to be durable enough to have a useful lifespan of several years.
What Medicare Requires
Several conditions generally have to be satisfied. The brace must be ordered by a physician or qualified healthcare provider, and your medical records must document why it is necessary — the diagnosis, your symptoms, and the functional impairment being addressed. You must obtain the brace from a supplier enrolled in the Medicare program; a device purchased from a non-enrolled supplier will not be reimbursed. It is worth asking whether the supplier accepts Medicare assignment, because suppliers who do can only charge you the applicable deductible and coinsurance.
What You Can Expect to Pay
Under Part B, after you meet the annual deductible — $257 in 2026 — Medicare typically pays 80% of the approved amount for a covered brace, leaving you responsible for the remaining 20% coinsurance. Those with a Medicare Supplement (Medigap) plan may find that this coinsurance is largely or entirely covered, depending on the plan. Individuals enrolled in Medicare Advantage should check with their specific plan, as cost-sharing and supplier networks can differ from Original Medicare.
Custom Versus Off-the-Shelf
Not all braces are billed the same way. Off-the-shelf devices require minimal customization, while a genuinely custom-fabricated brace is uniquely constructed or substantially modified for one specific patient according to a physician’s orders — a device that, by definition, no one else could use. Custom devices fall under different billing codes and typically carry more rigorous documentation requirements to establish that the custom approach is warranted for your particular situation.
The 2026 Update for Osteoarthritis
A significant change took effect on January 25, 2026. A revised Local Coverage Determination expanded Medicare coverage for knee braces used to treat medial or lateral tibiofemoral osteoarthritis — the offloading, or “unloader,” braces that shift pressure away from a worn compartment. Crucially, the update recognized that joint instability is not the only valid reason for a brace; coverage can now rest on documented osteoarthritis symptoms and functional impairment, provided the brace offers the appropriate varus or valgus adjustment. For younger and active patients trying to delay more invasive treatment, this broadened access is meaningful.
If a Claim is Denied
Coverage decisions are not always final. If Medicare declines to cover a brace you believe is medically necessary, you have the right to appeal, and denials are sometimes overturned when the supporting documentation is strengthened. The most common stumbling block is not the brace itself but the paper trail behind it — records that do not clearly establish medical necessity, or a missing detail in the physician’s order. Working closely with both your prescriber and a knowledgeable supplier to get the documentation right the first time is the single best way to avoid a denial, and to resolve one if it occurs.
How to Navigate the Process
Start with your physician, who can confirm the diagnosis and document medical necessity. Ask whether an off-the-shelf or custom brace is appropriate for your condition, then confirm that your chosen supplier is Medicare-enrolled and accepts assignment. Because coverage hinges on specific billing codes and documentation, it is entirely reasonable to ask the supplier directly whether your brace is expected to be covered and what your out-of-pocket cost is likely to be.
Medicare’s coverage of knee braces is real and, as of 2026, broader than it used to be — but it is conditional. The path to reimbursement runs through a clear diagnosis, proper documentation, and an enrolled supplier. When those pieces are in place, a medically necessary brace, including a custom one, is often within reach.
