Does Medicare cover knee braces?
Medicare Part B does cover knee braces as durable medical equipment when they're medically necessary and ordered by your doctor — but unsolicited 'free brace' phone or TV offers are a well-documented Medicare fraud scheme, not a real benefit.
What flips the answer
- Not covered when
There's no doctor's order and no documented medical necessity — a brace bought without a prescription, or ordered through an unsolicited telemarketing or TV ad, is not a legitimate Medicare claim and is a common fraud pattern.
- Not covered when
The supplier isn't enrolled in Medicare or doesn't accept assignment — Medicare won't pay its share, and you could be billed the full amount.
Knee braces fall under Medicare's orthotics and prosthetics category of DME, and Original Medicare Part B covers them when a doctor determines they're medically necessary — for example, for osteoarthritis, ligament instability, or post-surgical support. Coverage requires a doctor's written order and a supplier that's enrolled in Medicare and accepts assignment.
The coverage process matters as much as the medical necessity: the brace has to come from a Medicare-enrolled DME supplier, and Medicare only pays its share when that supplier accepts Medicare's approved amount as full payment (accepting assignment). Going through a non-enrolled or non-participating supplier can mean paying full price out of pocket even though the brace itself would otherwise qualify.
This benefit is also one of the most heavily exploited by fraud schemes. Scammers cold-call or advertise 'free' knee, back, or wrist braces to Medicare beneficiaries, get a Medicare number over the phone, and then bill Medicare for equipment that's never even sent — or send a low-quality unnecessary brace and bill Medicare for far more than it's worth. This is a well-documented and ongoing fraud pattern that the HHS Office of Inspector General and CMS have both flagged repeatedly. A legitimate knee brace under Medicare only ever starts with your own doctor's order, never with an unsolicited call or TV ad promising a 'free' brace.
How to actually get it covered
- 1
Get an in-person evaluation and written order from your doctor documenting medical necessity for the specific type of knee brace.
- 2
Choose a supplier enrolled in Medicare that accepts assignment — search the official directory at medicare.gov/medical-equipment-suppliers rather than responding to any unsolicited call, mailer, or ad.
- 3
Confirm the supplier bills Medicare directly with your order on file.
- 4
You pay 20% coinsurance after the Part B deductible; Medicare pays the rest of its approved amount.
- 5
If you ever receive an unsolicited call or ad offering a 'free' brace, do not give out your Medicare number — report it to 1-800-MEDICARE.
