Hip dysplasia surgery typically costs between $10,000 and $50,000, depending on the type of procedure, the patient’s age, and where the surgery is performed. That range spans everything from a pediatric hip reduction in a young child to a total hip replacement in an adult with long-standing dysplasia. Insurance covers most of these procedures, but out-of-pocket costs can still run into the thousands.
Pediatric Hip Dysplasia Surgery Costs
When hip dysplasia is caught in infancy or early childhood, surgery tends to be less extensive and less expensive than adult procedures. National hospital data from 2012 (the most recent large-scale analysis) put the average inpatient cost for developmental dysplasia of the hip at about $9,978 for children under 5 and $13,094 for children ages 6 to 10. Adjusted for medical inflation, those figures are meaningfully higher today.
Pediatric procedures range from a closed reduction (repositioning the hip joint under anesthesia without an incision) to open reduction and pelvic or femoral osteotomies, where the surgeon reshapes bone to create a more stable joint. A closed reduction is the least costly option, while osteotomies involve longer operating times, hardware like screws or plates, and a hospital stay of one to several days, all of which increase the bill. Casting and follow-up imaging after surgery add to the total as well.
Adult Hip Dysplasia Surgery Costs
Adults with hip dysplasia generally face one of two surgical paths: a periacetabular osteotomy (PAO), which reshapes the hip socket to improve coverage of the femoral head, or a total hip replacement if the joint has already developed significant arthritis. A PAO is a complex procedure performed at specialized centers, and total charges often fall in the $30,000 to $50,000 range before insurance. Because fewer surgeons perform PAOs, patients sometimes travel to high-volume centers, which can add travel and lodging expenses.
Total hip replacement is the more common procedure for adults whose dysplasia has progressed to end-stage arthritis. Medicare’s 2026 national average payment for a total hip replacement is $10,776 at an ambulatory surgical center and $14,278 at a hospital outpatient department. Those figures include the surgeon’s fee and the facility fee but represent what Medicare approves, not what a commercially insured or uninsured patient might be billed. Private insurance negotiated rates and list prices for uninsured patients are typically higher.
What You’ll Pay Out of Pocket
Your actual cost depends heavily on your insurance plan. For Medicare beneficiaries getting a total hip replacement, the patient’s share is roughly $2,154 at a surgical center or $1,968 at a hospital outpatient department, though Medicare caps outpatient copayments at $1,676 for most procedures. Private insurance plans vary widely. If you have a high-deductible plan, you could owe several thousand dollars before your coverage kicks in. Once you’ve met your deductible, most plans cover 80% to 90% of the approved amount, leaving you with a coinsurance payment.
Keep in mind that the surgeon’s bill is only part of the total. Anesthesia, implants or hardware, imaging, physical therapy, and any overnight hospital stay are billed separately. Pre-surgical costs like MRIs and consultations also add up. Ask your surgeon’s office for a complete estimate and confirm with your insurer which components are in-network.
Why Costs Vary So Much by Location
Geography is one of the biggest drivers of surgical cost in the United States. A 2022 analysis of total hip replacement prices across the 30 largest U.S. cities found that Dallas and Fort Worth were the most expensive at $50,580 on average, while El Paso came in at $23,260. That is more than a twofold difference for the same procedure. These figures include facility, surgeon, and anesthesia fees based on what health plans actually paid on claims.
Urban hospitals and academic medical centers tend to charge more than outpatient surgical centers or facilities in smaller cities. If your procedure is not urgent and you have flexibility, comparing facility costs within your insurance network can save thousands. Many insurers now offer price transparency tools, and independent resources like Healthcare Bluebook let you look up fair prices by zip code.
Factors That Affect Your Total Bill
- Type of procedure: A closed reduction in an infant costs far less than a pelvic osteotomy or total hip replacement in an adult.
- Inpatient vs. outpatient: Procedures done in outpatient surgical centers are consistently cheaper than those requiring a hospital admission. Medicare data shows a difference of about $3,500 between the two settings for a hip replacement alone.
- Surgeon specialization: Complex reconstructive procedures like a PAO are performed at a limited number of centers, which can mean higher facility fees but often better outcomes.
- Implants and hardware: If your surgery involves metal plates, screws, or a prosthetic joint, the cost of those devices is a significant line item, sometimes thousands of dollars on its own.
- Rehabilitation: Physical therapy after hip surgery typically runs 6 to 12 weeks. Copays for two or three sessions per week add up quickly.
Ways to Reduce Your Costs
If you’re uninsured or facing a high deductible, ask the hospital’s billing department about a cash-pay discount. Many facilities offer 20% to 40% off for patients who pay upfront or set up a payment plan before surgery. Nonprofit hospitals are also required to have financial assistance programs for patients who qualify based on income.
Timing your surgery to align with your insurance deductible cycle can also help. If you’ve already met a large portion of your annual deductible from other medical expenses, scheduling surgery later in that same plan year means you’ll owe less out of pocket. For pediatric cases, state Medicaid programs and the Children’s Health Insurance Program (CHIP) cover hip dysplasia surgery with minimal or no cost sharing for eligible families.
