Understanding Medicare Coverage for Hip Replacement Surgery
Hip replacement surgery is one of the most common orthopedic procedures in the United States, with approximately 370,000 procedures performed annually according to the Agency for Healthcare Research and Quality. Medicare, the federal health insurance program for people age 65 and older, covers hip replacement surgery when medically necessary. However, understanding what Medicare covers and what you may pay out-of-pocket requires understanding the different parts of Medicare and how they work together.

Medicare Part A covers hospital inpatient services, which includes the surgical procedure itself, operating room costs, anesthesia, and the hospital stay. Most hip replacements are performed as inpatient procedures, meaning you stay in the hospital overnight. Medicare Part B covers the surgeon's fees and other physician services. Together, these two parts form the foundation of your coverage for hip replacement.
The actual costs you face depend on several factors: whether you have Original Medicare or a Medicare Advantage plan, your deductible status, whether you're in the hospital's service area where you receive care, and whether your surgeon accepts Medicare assignment. A person with Original Medicare who had hip replacement surgery in 2023 paid approximately $1,412 in Part A deductible costs plus additional coinsurance amounts for extended hospital stays.
It's important to note that Medicare does not cover the entire cost of your procedure. You will have financial responsibility for certain amounts. Understanding these costs before surgery allows you to plan financially and make informed decisions about your care. Speaking with your hospital's billing department and your surgeon's office before the procedure helps clarify what you'll owe.
Practical Takeaway: Request an itemized cost estimate from your hospital and surgeon's office at least 30 days before your scheduled hip replacement surgery. This estimate should include facility charges, surgeon fees, and any other associated costs, allowing you to understand your financial responsibility.
How Original Medicare Pays for Hip Replacement
Original Medicare, also called Traditional Medicare, consists of Part A (hospital insurance) and Part B (medical insurance). When you undergo hip replacement surgery with Original Medicare, the payment process involves your deductible, coinsurance, and copayments at different stages of your care.

For the inpatient hospital portion covered under Part A, you pay a deductible for each benefit period. In 2024, this deductible is $1,632. After you meet this deductible, Medicare covers your hospital costs for the first 60 days of your stay. Days 61 through 90 require you to pay coinsurance of $408 per day (in 2024). If your stay extends beyond 90 days, costs increase further. Most hip replacement patients stay in the hospital for one to three days, so many will only pay the Part A deductible and no additional coinsurance.
Part B covers your surgeon's fees and other physician services related to your surgery. You pay 20% of the approved amount for these services after you meet your Part B deductible, which is $240 in 2024. Your surgeon must accept Medicare assignment, meaning they accept Medicare's approved amount as payment in full. If your surgeon does not accept assignment, you may owe additional amounts beyond Medicare's approved fee.
Post-operative care covered by Original Medicare includes follow-up visits with your surgeon, physical therapy, and other medically necessary services. Physical therapy may be covered under Part A if you receive it as an inpatient, or under Part B if you receive outpatient therapy at a rehabilitation facility or your surgeon's office. You pay coinsurance for Part B services even after meeting your deductible.
The structure of Original Medicare means your total costs depend heavily on the specifics of your surgery and recovery. Someone with a straightforward hip replacement and one-day hospital stay might pay around $1,872 in Medicare-required costs (the Part A deductible plus 20% of surgeon and anesthesia fees). Someone with complications requiring a longer stay could pay considerably more.
Practical Takeaway: Before your surgery, verify that your surgeon accepts Medicare assignment. Call your surgeon's billing office and ask for written confirmation. Also ask which hospitals they operate at and confirm those facilities are in your Medicare network.
Medicare Advantage Plans and Hip Replacement Coverage
Medicare Advantage plans, also called Medicare Part C, are an alternative way to receive your Medicare benefits. These plans are offered by private insurance companies and must cover everything Original Medicare covers, but they often do so with different cost structures. Approximately 42% of Medicare beneficiaries are enrolled in Medicare Advantage plans according to the Centers for Medicare & Medicaid Services.

With a Medicare Advantage plan, your hip replacement surgery remains covered, but your out-of-pocket costs may differ significantly from Original Medicare. Instead of paying a deductible and 20% coinsurance, Medicare Advantage plans typically charge a copayment for surgery. This copayment might be a fixed amount, such as $500 or $1,000, depending on your specific plan. Many Medicare Advantage plans also have annual out-of-pocket maximums, which means once you reach a certain amount in total costs for the year, the plan covers remaining services at no additional cost to you.
Medicare Advantage plans often require you to use network providers. This means your surgeon and hospital must be part of your plan's network, or you may face higher costs or limited coverage. Before scheduling surgery, contact your Medicare Advantage plan to confirm your surgeon and the facility where surgery will occur are in-network. Plans also frequently require prior authorization for surgery, meaning your surgeon's office must receive advance approval from the plan before the procedure is scheduled.
The trade-off with Medicare Advantage plans is that while your upfront surgery costs may be lower than Original Medicare, you have less flexibility in choosing your provider and you're bound by the plan's rules about which hospitals and doctors you can see. Additionally, some Medicare Advantage plans include supplemental benefits like dental, vision, or fitness programs that Original Medicare doesn't cover, though these vary by plan.
Your Medicare Advantage plan documents outline exactly what you'll pay for hip replacement surgery. These documents are complex, so calling your plan's member services line and speaking with a representative about your specific plan's coverage is worthwhile. Ask them to explain in writing what your copayment will be and whether any prior authorization is needed.
Practical Takeaway: Review your Medicare Advantage plan's summary of benefits at least two months before your planned hip replacement surgery. Contact your plan to confirm your surgeon is in-network and request written documentation of your copayment responsibility and any prior authorization requirements.
Supplemental Insurance and Medigap Coverage for Hip Replacement
Medigap policies, also called Medicare supplemental insurance, are additional insurance policies you can purchase to help cover costs that Original Medicare doesn't pay. These policies help cover the coinsurance, copayments, and deductibles that Medicare leaves for you to pay. Approximately 27% of Original Medicare beneficiaries have some form of Medigap coverage.

There are 10 standardized Medigap plans, labeled A through N. Each plan offers different coverage levels. For example, Medigap Plan F covers your Part A deductible, Part B deductible, Part B coinsurance, and other costs. If you have Plan F and undergo hip replacement surgery, your Medigap policy would pay the $1,632 Part A deductible and help cover the 20% coinsurance you owe for surgeon fees and other Part B services. This means you might have minimal out-of-pocket costs beyond your plan's premiums.
However, not all Medigap plans cover all costs equally. Medigap Plan G, for example, covers most of the same services as Plan F except the Part B deductible. Plan K covers a smaller percentage of costs. The monthly premium you pay for your Medigap policy varies based on which plan you choose and your age, location, and health status at the time you purchase it. In 2024, Medigap premiums range from approximately $100 to $300+ per month depending on your location and plan type.
An important consideration is that if you have a Medicare Advantage plan, you should not purchase Medigap coverage. Medicare prohibits Medigap policies from being sold to Medicare Advantage enrollees, and Medigap policies do not work with Medicare Advantage plans. Additionally, if you let your Medigap coverage lapse and later want to re-enroll, you may face higher premiums or medical underwriting, depending on your state's rules.
