Understanding Medicare Coverage for Hip Replacement Surgery

Hip replacement surgery is one of the most common orthopedic procedures performed in the United States, with more than 370,000 procedures done annually. Medicare, the federal health insurance program for people 65 and older, covers hip replacement surgery when medically necessary. Understanding how this coverage works is the first step in managing the costs associated with this procedure.

Hip replacement, also called hip arthroplasty, involves removing a damaged hip joint and replacing it with an artificial joint. Common reasons for this surgery include severe osteoarthritis, rheumatoid arthritis, hip fractures, and other conditions that cause significant pain and limit movement. When a doctor determines that hip replacement is medically necessary and conservative treatments have been tried, Medicare typically covers the procedure.

Medicare consists of several parts, each covering different services. Part A covers hospital stays, including the inpatient stay for hip replacement surgery. Part B covers physician services and outpatient care. Together, these parts cover the majority of hip replacement costs, but beneficiaries still have out-of-pocket expenses. The surgery itself, hospital facility fees, anesthesia, and post-operative care are all covered under Part A when the procedure is performed as an inpatient admission.

It is important to know that Medicare does not pay 100 percent of hip replacement costs. Beneficiaries pay deductibles, copayments, and coinsurance amounts. The exact amount depends on the specific Medicare plan and whether the person also has supplemental coverage. Understanding these cost-sharing requirements helps people prepare financially for the procedure.

Practical Takeaway: Contact your doctor to discuss whether hip replacement is medically necessary for your condition. Once your doctor recommends surgery, request information about the expected hospital stay length and recovery timeline, as this affects your Medicare cost-sharing obligations.

How Medicare Part A Covers Hip Replacement Hospital Costs

Medicare Part A is the hospital insurance portion of Medicare that covers inpatient hospital stays. When you have hip replacement surgery, you will typically stay in the hospital for one to three days. Medicare Part A covers the hospital facility charges, nursing care, medications administered during your stay, and use of operating rooms and equipment.

To receive Part A coverage for hip replacement, you must meet two requirements. First, your doctor must admit you as an inpatient to the hospital, meaning you stay overnight. Second, the surgery must be deemed medically necessary by Medicare standards. Medicare does not cover elective surgeries performed purely for cosmetic or quality-of-life reasons if the condition does not significantly impair function or cause severe pain.

Part A coverage includes several components of your hospital stay. The surgical team, operating room, anesthesia services, and surgical supplies are all covered. During recovery in the hospital, nursing care, medications given intravenously, meals, and a hospital room are covered. Rehabilitation services provided during your inpatient stay, such as physical therapy beginning the day after surgery, are also included in Part A coverage.

However, Part A does not cover all costs. You pay a deductible for each hospital stay, which in 2024 is $1,632. After you pay the deductible, Medicare covers all reasonable charges for days 1 through 60 of your hospital stay. From days 61 through 90, you pay a daily copayment of $408. If your stay extends beyond 90 days, you enter a "lifetime reserve" period where you pay a higher copayment. Most hip replacement patients are discharged within 3 days, so they typically only pay the deductible.

Practical Takeaway: Before surgery, ask the hospital billing department to estimate your Part A deductible and any copayments based on the expected length of stay. If you have already met your deductible earlier in the year, you may owe nothing for the hospital portion of hip replacement.

Medicare Part B Coverage for Physician and Professional Services

Medicare Part B is the medical insurance portion of Medicare that covers physician services, outpatient care, and other medical services. For hip replacement, Part B covers your surgeon's fees, the anesthesiologist's charges, and various professional services related to your procedure and recovery.

Your orthopedic surgeon performs the hip replacement surgery and manages your care. The surgeon's professional fee is covered under Part B. Additionally, the anesthesiologist who administers anesthesia during surgery and monitors you throughout the procedure bills separately, and this charge is also covered by Part B. Other physicians who may see you during your hospital stay, such as a cardiologist if you have heart conditions, are covered under Part B as well.

Part B also covers physician services in the weeks following your surgery. Post-operative visits where your surgeon examines your incision, checks your progress, and manages your recovery are covered. If you develop complications or have concerns during recovery, follow-up appointments are covered. Physical therapy prescribed by your physician and performed by a licensed physical therapist is covered under Part B after you leave the hospital.

Similar to Part A, Part B requires you to pay costs before Medicare begins paying. You pay a Part B deductible, which is $240 in 2024. After meeting the deductible, you typically pay 20 percent coinsurance on most Part B services. This means if your surgeon's fee is $1,000, Medicare pays $800 and you pay $200. For outpatient physical therapy, you pay 20 percent of the cost after the deductible. Many people who have supplemental insurance (Medigap) or Medicare Advantage plans have this coinsurance covered, reducing their out-of-pocket costs.

Practical Takeaway: Request an itemized estimate from your surgeon's office that lists all charges that will be billed to Medicare Part B. Ask whether your surgeon participates with Medicare and accepts Medicare assignment, meaning they agree to accept Medicare's approved amount as payment in full.

Understanding Out-of-Pocket Costs and Cost-Sharing

While Medicare covers a significant portion of hip replacement costs, beneficiaries have out-of-pocket expenses through deductibles, copayments, and coinsurance. Understanding these costs helps you prepare financially and potentially explore options to reduce them.

The Part A deductible is paid once per hospital benefit period and covers all inpatient hospital stays within that period. In 2024, this deductible is $1,632. If your hip replacement surgery is your only hospital stay that year, you pay this deductible. However, if you were hospitalized earlier in the year for another condition and already paid the deductible, you owe nothing for the hospital portion of hip replacement.

Part B coinsurance is typically 20 percent of the approved amount for services. Your surgeon might charge $5,000 for hip replacement surgery, but Medicare's approved amount might be $3,500. You would pay 20 percent of $3,500 (which is $700) after meeting your deductible. If your surgeon does not accept Medicare assignment, you could owe more. Orthopedic surgeons typically accept Medicare assignment, but you should verify this before surgery.

Total out-of-pocket costs for hip replacement under Original Medicare typically range from $1,500 to $3,500, depending on your specific situation. This amount varies based on whether you have already met deductibles earlier in the year, whether you have supplemental insurance, and your surgeon's specific charges. Many beneficiaries have Medigap policies that cover deductibles and coinsurance, reducing or eliminating their out-of-pocket costs for hip replacement.

Some hospitals and surgical centers offer financial assistance programs or payment plans for uninsured or underinsured patients. While you have Medicare, the hospital may still offer payment arrangements if you need additional help managing copayments or deductibles. Speak with the hospital's financial counselor before your procedure to learn about these options.

Practical Takeaway: Calculate your potential out-of-pocket costs by adding any remaining deductible from earlier in the year, any coinsurance you will owe, and any costs for post-operative care. If this amount is substantial, ask whether you need supplemental insurance (Medigap) or whether the hospital offers payment plans.

Supplemental Insurance and Medicare Advantage Plan Options

Many Medicare beneficiaries purchase supplemental insurance or enroll in Medicare Advantage plans to reduce out-of-pocket costs for procedures like hip replacement. Understanding these options helps you determine whether additional coverage might benefit
