Medicare covers bunion surgery, but only if a doctor documents that the bunion is causing you pain or functional problems — not for appearance alone
Medicare Part B will pay for bunion surgery if your doctor determines it is medically necessary. The key word is medically necessary. Medicare does not cover cosmetic foot surgery. If your bunion is painful, limits how far you can walk, or makes it hard to wear normal shoes because of pain (not just fit), you have a stronger case for coverage. Your doctor needs to document the problem in your medical record before surgery is scheduled.
You will pay 20 percent of the approved amount after you meet your Part B deductible for the year. The surgeon's office will submit the claim to Medicare, and Medicare will tell you what it approves. The actual cost depends on where you live and which surgeon performs the procedure, because Medicare pays different amounts in different regions.
Key Takeaways
- Medicare covers bunion surgery only when a doctor documents that the bunion causes pain or limits your ability to walk or wear shoes, not for cosmetic reasons.
- Your doctor must submit documentation to Medicare before surgery showing the medical reason for the procedure.
- You pay 20 percent of Medicare's approved amount after meeting your Part B deductible, which resets each January.
- The approved amount varies by region, so ask your surgeon's office what Medicare typically pays in your area.
- If Medicare denies the claim, you have the right to request a review and provide additional medical evidence.
How Medicare decides whether bunion surgery is medically necessary
Medicare uses specific criteria to decide whether a bunion qualifies for coverage. The bunion must be causing you pain that interferes with daily activities, or it must be limiting your ability to walk, stand, or wear shoes. straightforward having a bunion that looks odd or feels slightly uncomfortable is not enough. Your doctor needs to examine you, document your symptoms in writing, and explain why surgery is the right treatment rather than other options like padding, taping, or different shoes.
Your doctor should note in your medical record things like: how long you have had pain, what activities the pain stops you from doing, whether you have tried non-surgical treatments and how they worked, and why surgery is necessary now. If you have tried shoe inserts, bunion pads, or anti-inflammatory medications and they have not helped, mention that to your doctor. This history strengthens the case that surgery is medically necessary rather than elective.
What you pay out of pocket
Your costs depend on whether you have met your Part B deductible for the year. The Part B deductible is the amount you must pay out of pocket before Medicare starts paying its share. In 2024, the Part B deductible is $240, but this amount changes each year. Once you have paid that deductible, Medicare pays 80 percent of the approved amount, and you pay 20 percent.
The approved amount is what Medicare decides the surgery is worth in your region — not necessarily what the surgeon charges. If your surgeon charges more than Medicare approves, you may owe the difference. Ask your surgeon's office before the procedure what the Medicare-approved amount is and what your 20 percent share will be. If you have a Medigap policy or Medicare Advantage plan, your out-of-pocket costs may be lower, depending on your plan.
Getting Medicare approval before surgery
Your surgeon's office should handle submitting the medical documentation to Medicare. You do not need to submit it yourself. However, you should make sure your doctor's office knows you have Medicare and that they understand Medicare's requirements. Ask them directly: "Will you submit the medical information to Medicare before surgery to make sure it is covered?" This step is important because if Medicare denies the claim after surgery, you could be responsible for the full cost.
Some surgeons' offices will request a pre-authorization from Medicare before scheduling your surgery. This is a formal review where Medicare looks at your medical records and tells the surgeon whether the surgery meets Medicare's criteria. Pre-authorization is not required, but it protects you by confirming coverage before you have the procedure. If your surgeon's office does not mention pre-authorization, you can ask them to request it.
What happens if Medicare denies your claim
If Medicare denies coverage, you have the right to request a review. This is called an appeal. You have 120 days from the date you receive the denial notice to file an appeal. In the appeal, you can submit additional medical evidence — for example, photos of your foot, notes from your doctor about your pain, or records showing you tried other treatments first.
The appeal process has several levels. The first level is called redetermination, where a Medicare contractor reviews the denial. If you disagree with that decision, you can request reconsideration, where a different reviewer looks at your case. If you still disagree, you can request a hearing before an administrative law judge. Your surgeon's office or a patient advocate can help you gather the medical evidence needed for an appeal.
Medicare Advantage plans and bunion surgery coverage
If you have a Medicare Advantage plan instead of Original Medicare, your coverage for bunion surgery may be different. Medicare Advantage plans must cover at least what Original Medicare covers, but they can have different rules about pre-authorization, which surgeons you can see, and how much you pay out of pocket. Some plans require you to see a surgeon in their network, and some require pre-authorization before any surgery.
Call your Medicare Advantage plan's customer service number before scheduling surgery and ask: "Does my plan cover bunion surgery if my doctor says it is medically necessary? Do I need pre-authorization? Which surgeons are in my network?" Your plan will tell you what your costs will be and what steps you need to take.
Questions to ask your doctor before scheduling bunion surgery
Before you move forward with surgery, have a conversation with your doctor about whether Medicare is likely to cover it. Ask: "Is my bunion causing enough pain or functional limitation that Medicare would consider this medically necessary?" and "Will you document in my medical record why surgery is the right treatment for me?" Also ask whether your doctor has submitted cases like yours to Medicare before and what the typical outcome was.
If your doctor is unsure whether Medicare will cover the surgery, ask whether the office can request pre-authorization from Medicare. This gives you a clear answer before you schedule the procedure. If your doctor thinks Medicare might deny the claim, discuss whether you want to proceed anyway and pay out of pocket, or whether you want to try non-surgical treatments first.
Frequently Asked Questions
Will Medicare cover bunion surgery if it is not causing me pain right now?
No. Medicare requires that the bunion cause pain or limit your ability to walk or wear shoes. If you have a bunion that looks unusual but does not hurt, Medicare will not cover surgery. If your pain develops later, you can discuss surgery with your doctor at that time.
What if I have already had bunion surgery and paid out of pocket — can I get reimbursed?
No. Medicare does not reimburse for surgery that was already performed and paid for before you contacted Medicare. If you are considering bunion surgery, contact Medicare or your surgeon's office before the procedure to confirm coverage.
Does Medicare cover bunion surgery on both feet at the same time?
Yes, if both bunions are medically necessary. However, some surgeons prefer to operate on one foot at a time so you can walk and care for yourself while one foot heals. Discuss with your surgeon what approach makes sense for your situation, and make sure your doctor documents that both bunions require surgery.
What if my surgeon is not in the Medicare network?
If you have Original Medicare, there is no network — any doctor who accepts Medicare can treat you. If you have a Medicare Advantage plan, you may need to use an in-network surgeon, or you may pay more if you see an out-of-network surgeon. Check your plan's rules before scheduling.
How long does it take Medicare to approve bunion surgery?
If your surgeon requests pre-authorization, Medicare typically responds within 5 to 10 business days. If you wait until after surgery to submit the claim, processing can take 2 to 4 weeks. Requesting pre-authorization before surgery is faster and gives you certainty about coverage.
