Understanding Medicare Coverage for Hip Replacement Surgery

Hip replacement surgery is one of the most common procedures performed in the United States, with over 370,000 procedures completed annually according to recent data from the National Institutes of Health. Medicare, the federal health insurance program for people age 65 and older, covers hip replacement surgery when certain conditions are met. This guide provides information about how Medicare's coverage works for this orthopedic procedure, what costs you might encounter, and what to expect throughout the process.

Hip replacement, medically known as total hip arthroplasty, involves replacing a damaged hip joint with an artificial implant. The procedure typically takes one to two hours and is performed when arthritis, injury, or other conditions make the joint severely painful or limit movement. Medicare Part B, which covers outpatient services and hospital procedures, generally covers hip replacement surgery when a doctor determines it is medically necessary.

The coverage structure depends on where the surgery takes place. If your surgery occurs in a hospital's outpatient department or as an inpatient stay, Medicare Part A (hospital insurance) covers the facility costs. If performed at an ambulatory surgical center, Part B typically covers the procedure. Understanding which setting applies to your situation affects your out-of-pocket costs and the coverage rules that apply.

Medicare's approach to hip replacement coverage focuses on medical necessity rather than age alone. This means that even patients under 65 who have Medicare due to disability or End-Stage Renal Disease may receive coverage if a physician documents that surgery is medically necessary. The determination of medical necessity typically involves documentation of conservative treatment attempts, imaging studies showing joint damage, and physician recommendations for surgical intervention.

Practical takeaway: Review your Medicare coverage type (Original Medicare, Medicare Advantage, or other plans) before scheduling hip replacement surgery, as coverage details vary by plan type. Contact your plan directly to understand your specific coverage terms, as different plans may have different rules about which hospitals or surgical centers participate in their networks.

Medicare Part A and Part B Coverage Details

Original Medicare consists of Part A and Part B, which work together to cover hip replacement surgery. Part A covers inpatient hospital stays, including the facility, nursing care, meals, and standard hospital services during your recovery. Part B covers the surgeon's fees, anesthesia, and related medical services. When you have both parts, they coordinate to provide coverage for the complete surgical experience.

If your hip replacement is performed as an inpatient procedure, meaning you spend at least one night in the hospital, Part A becomes your primary coverage for facility costs. Part A requires you to pay a deductible before coverage begins—in 2024, this deductible is $1,676 per benefit period. After you pay the deductible, Part A covers all approved facility costs for days 1-60 of your hospital stay at no additional cost. For days 61-90, you pay a daily copayment of $419 per day. This structure means that most hip replacements, typically requiring 1-3 days of hospitalization, fall within the fully covered period after the deductible.

Part B covers the surgeon's services, assistant surgeon (if needed), anesthesiologist, and other physician services related to your surgery. Part B requires an annual deductible ($240 in 2024) and then covers 80 percent of approved charges after that deductible is met. You are responsible for the remaining 20 percent, known as coinsurance. This means if your surgeon charges $5,000, and Medicare approves $4,500, you would pay 20 percent of $4,500, or $900, after meeting your Part B deductible.

It is important to understand that Medicare pays based on "approved amounts," which may differ from what a provider actually charges. Providers who accept Medicare assignment agree to accept the Medicare-approved amount as payment in full, except for deductibles and coinsurance. This protects you from unexpected billing surprises. Surgeons and hospitals performing hip replacements typically participate in Medicare and accept assignment, but it is wise to confirm this before your procedure.

Practical takeaway: Before scheduling surgery, request an estimate of the Medicare-approved amount for your surgeon's services and hospital facility charges. Ask your provider's billing department to calculate your expected out-of-pocket costs based on whether you have already met your deductibles for the year. This simple step can help you budget for your surgery and avoid billing surprises.

Out-of-Pocket Costs and Financial Planning

Hip replacement surgery involves several categories of out-of-pocket costs under Original Medicare. These costs accumulate in a specific order based on Medicare's deductible and coinsurance structure. Understanding these costs in advance allows you to plan financially and explore options like Medigap or Medicare Advantage coverage that might reduce your expenses.

The primary out-of-pocket costs include deductibles, coinsurance, and any charges above Medicare's approved amounts. If you have not met your Part A deductible for the year, you pay $1,676 before Part A coverage begins. Your Part B deductible is separate and totals $240 annually. Once deductibles are met, you typically pay 20 percent coinsurance on Part B-covered services. For a typical hip replacement with surgeon fees around $4,500 (approved amount), you would pay approximately $900 in Part B coinsurance after your deductible is met.

Facility costs vary significantly based on your geographic location and the hospital or surgical center where your procedure occurs. Urban hospitals generally charge more than rural facilities, and costs in high-cost areas can be substantially higher. Medicare's approved amount for facility charges is determined by the Outpatient Prospective Payment System (OPPS) for ambulatory surgery centers or the Inpatient Prospective Payment System (IPPS) for hospital inpatient stays. Your facility billing department can provide an estimate of these approved amounts.

Additional costs may include post-operative items not covered by Medicare. Physical therapy, occupational therapy, and home health services following surgery may be covered by Medicare Part B and Part A, respectively, but typically involve coinsurance or copayments. Durable medical equipment such as walkers, canes, crutches, and raised toilet seats are covered at 80 percent after deductible under Part B. Medications, including pain management prescriptions, are covered under Part D (prescription drug coverage) with copayments determined by your specific plan.

Many people with Original Medicare purchase supplemental insurance called Medigap. These policies, sold by private insurers, cover some or all of your Medicare deductibles and coinsurance. Medigap Plan G and Plan F (for those eligible) typically cover the Part A deductible and Part B coinsurance, potentially reducing your out-of-pocket costs to near zero for hip replacement surgery. However, Medigap premiums vary by location and age, so you should compare costs between Medigap coverage and your current out-of-pocket costs under Original Medicare alone.

Practical takeaway: Create a written budget for your hip replacement that includes the Part A deductible, Part B deductible, coinsurance percentages, estimated facility charges, surgeon fees, and post-operative supplies or therapy. Contact your surgeon's office and hospital billing department for itemized estimates. If your out-of-pocket costs exceed your ability to pay, ask your hospital's financial counselor about payment plans or charity care programs.

Medicare Advantage Plans and Hip Replacement Coverage

Medicare Advantage, also called Medicare Part C, is an alternative way to receive Medicare benefits through private insurance companies. Approximately 28 million people, or about 42 percent of Medicare beneficiaries, are enrolled in Medicare Advantage plans. These plans must cover everything that Original Medicare covers, including hip replacement surgery, but they often structure costs differently and may include additional services not available under Original Medicare.

Medicare Advantage plans typically use network providers, meaning you must receive care from doctors and hospitals within the plan's network to receive the highest level of coverage. Before scheduling hip replacement surgery, verify that your preferred orthopedic surgeon and hospital participate in your plan's network. Out-of-network care is usually possible but involves significantly higher out-of-pocket costs. Plans generally require prior authorization for major surgery, meaning your surgeon must obtain approval from the plan before scheduling your hip replacement.

Cost structures in Medicare Advantage plans vary widely. Many plans charge a copayment for inpatient hospital stays—for example, $300 to $500 per admission—rather than a percentage coinsurance. Others use a daily copayment structure. Surgeon and physician services may be covered with a copayment ranging
