Does Medicare cover ankle replacement?
Total ankle replacement (ankle arthroplasty) is covered by most major insurers as an alternative to ankle fusion for end-stage ankle arthritis. Coverage criteria typically require imaging-confirmed severe ankle arthritis, failed conservative care, and assessment by a foot and ankle specialist experienced in ankle replacement. Some older insurance policies and certain Medicaid plans still classify ankle replacement as investigational - verify with your specific plan.

Prior authorization for Medicare
Medicare Part B covers orthopedic office visits, diagnostic imaging, and outpatient procedures. Part A covers inpatient surgical procedures like joint replacements. Medicare typically covers 80% of approved amounts after the annual deductible, with the remaining 20% covered by supplemental insurance (Medigap) or paid out of pocket. No referrals are needed for specialists under Original Medicare.
Always verify your specific Medicare plan before scheduling. Plans within the same insurer (Medicare) can have different prior authorization rules, network requirements, and cost-sharing. Call the number on the back of your insurance card or log into your plan portal to confirm coverage for your specific plan.
How to confirm your coverage before scheduling
- 1Call Medicare member services (number on back of your insurance card) and ask specifically if ankle replacement is covered under your plan.
- 2Ask your orthopedic surgeon's office to verify benefits on your behalf - they do this routinely and can identify in-network requirements.
- 3Request the prior authorization criteria in writing if prior auth is required. Ask what documentation is needed from your surgeon.
- 4Confirm your deductible remaining for the year - your out-of-pocket cost depends on where you are in the deductible cycle.
- 5Get a pre-service cost estimate from the facility if you want a specific dollar figure before scheduling.
What to do if Medicare denies coverage
Insurance denials for orthopedic procedures are common and frequently overturned on appeal. Follow these steps:
- 1Confirm your plan does not classify ankle replacement as investigational
- 2Provide imaging documenting end-stage ankle arthritis
- 3Document failed conservative treatment (PT, bracing, injections)
- 4Submit surgeon's clinical notes supporting ankle replacement over fusion
- 5Request peer-to-peer review if denied - emphasize functional preservation advantages
