Total hip replacement (total hip arthroplasty) removes the damaged ball-and-socket joint and substitutes a metal femoral stem, a ceramic or metal ball, and a polyethylene or ceramic acetabular liner. The operation usually runs 60 to 120 minutes under spinal or general anesthesia. Most patients stay one to two nights in the hospital — or go home the same day under modern outpatient protocols — and then work with a physical therapist for six to twelve weeks. The total episode of care includes the surgeon, anesthesia, the implant itself, the hospital or ASC facility fee, inpatient therapy, and outpatient PT, so quoted prices should always be compared on a bundled basis. Implant choice (brand, bearing surface, robotic-assisted vs manual technique) and site of service (hospital vs ASC) are the two largest cost levers. Commercial plans almost always require prior authorization, and some offer center-of-excellence programs that pay for travel to a designated high-volume surgeon.
費用に影響する要素
- Site of service: ambulatory surgery centers now handle many healthy outpatient hip replacements and typically bill 25-40% less than a hospital inpatient stay.
- Implant selection: ceramic-on-polyethylene, ceramic-on-ceramic, and dual-mobility cups carry different device prices; branded implants can add thousands over baseline.
- Surgical technique: robotic-assisted or computer-navigated procedures add equipment charges the facility passes through to the patient.
- Anesthesia approach: spinal anesthesia with a nerve block is often less expensive than full general anesthesia and can shorten the hospital stay.
- Length of stay and rehab setting: discharge to home with outpatient PT is far cheaper than a skilled nursing facility or inpatient rehab stay.
- Bundled-payment participation: hospitals in CMS bundled programs often offer more predictable pricing than open fee-for-service billing.
節約方法
- Ask whether you qualify for outpatient hip replacement at an ambulatory surgery center; eligibility depends on age, BMI, and comorbidities.
- Request a bundled all-in price from the surgeon's office covering surgeon, facility, anesthesia, implant, and post-operative therapy.
- Check whether your employer or insurer offers a center-of-excellence program — many waive copays and deductibles plus cover travel stipends.
- Confirm the surgeon, anesthesiologist, and any assisting provider are in-network; the No Surprises Act protects you, but proactive verification avoids billing disputes.
- Line up home-based physical therapy rather than a skilled nursing facility if medically appropriate — the cost difference is substantial.
- Use your HSA or FSA for deductible and coinsurance payments, and ask the hospital about prompt-pay discounts before settling the bill.
保険とカバレッジに関する注意事項
Medicare Part A covers inpatient hip replacement; Medicare Part B covers the surgeon, anesthesia, and outpatient rehab. Since CMS removed total hip arthroplasty from the inpatient-only list, outpatient ASC coverage is also available for appropriate candidates. Commercial plans cover medically necessary hip replacement but almost always require prior authorization, often with documentation of a failed course of conservative therapy such as physical therapy, NSAIDs, weight loss, or injections. Expect to owe your full deductible plus coinsurance — the out-of-pocket maximum is often reached on this single episode. Medicare Advantage plans can impose step therapy. Preoperative medical clearance labs and cardiology visits are billed separately.
