Hip Replacement Surgery Cost in 2026: Full Breakdown

Total hip arthroplasty is among the most common and most costly surgical procedures in the United States—more than 450,000 are performed each year. Without insurance, the total charge can exceed $70,000. Medicare pays the hospital a bundled $12,000–$18,000 for the same procedure. That enormous gap between charged amounts and actual payment creates fertile ground for billing errors, which BillKarma finds in 29% of hip replacement claims. This guide breaks down every cost component, explains Medicare’s DRG payment system, and gives you the questions to ask before and after surgery to protect your wallet.

1. Cost components: surgeon, facility, implant, and rehab

A hip replacement bill does not arrive as one number. Multiple providers bill separately, and some charges appear weeks after discharge. Here is every major cost component and its typical range:

The total charged amount ($30,000–$70,000) looks alarming, but it is the hospital’s “chargemaster” rate—not what any payer actually pays. Medicare’s DRG payment is $12,000–$18,000 for the entire inpatient episode. Commercial insurers negotiate rates typically 150–250% of Medicare. Cash-pay rates at hospitals are often available on request and may be significantly lower than the chargemaster rate.

2. How Medicare pays for hip replacement (DRG 470)

Medicare reimburses hospital inpatient procedures through a system of Diagnosis-Related Groups (DRGs). Rather than paying itemized charges, Medicare pays a single bundled amount per episode based on the diagnosis and procedure. Hip replacement falls under:

• MS-DRG 470: Major joint replacement of the lower extremity without major complication or comorbidity (MCC). Medicare pays approximately $12,000–$15,000 depending on the hospital’s geographic wage index and teaching status.
• MS-DRG 469: Major joint replacement with MCC (significant comorbidities like severe heart disease, kidney disease, or active infection). Medicare pays approximately $18,000–$22,000.

The DRG payment is all-inclusive for the facility—it covers the operating room, the implant device, nursing care, standard medications, and most ancillary services during the hospitalization. The hospital cannot bill Medicare separately for the hip implant as though it were an additional item on top of the DRG. If your itemized bill shows a separate implant charge alongside a DRG code on a Medicare claim, that is a potential billing error.

The surgeon and anesthesiologist bill separately under Medicare Part B, as the DRG only covers the facility. Your Part A deductible ($1,676 in 2026) covers the first 60 days of inpatient care with no daily coinsurance. After day 60, coinsurance of $419/day applies through day 90.

3. Implant types and cost: titanium, ceramic, and metal

The hip implant device—the femoral stem, femoral head, acetabular cup, and liner—is one of the largest cost components in the procedure. Different material combinations have different longevity profiles, price points, and complication risks.

Hospitals purchase implants at wholesale prices—often $1,500–$4,000—and mark them up significantly in their chargemaster. Under Medicare DRG rules, the implant cost is already factored into the DRG payment rate; no separate billing is permitted. For commercial insurance patients, implant billing is sometimes separated as a device line item, and the markup can be substantial. If you see a device or implant line item exceeding $10,000 on your commercial insurer’s EOB, it is worth requesting an audit of the specific device billed.

4. Hospital vs. ambulatory surgery center

Total hip arthroplasty was added to Medicare’s ASC-eligible procedure list in 2020, and CMS has continued to expand outpatient hip replacement coverage since. For appropriately selected patients—generally healthy adults under 70 with no significant cardiac or pulmonary comorbidities and good home support—outpatient hip replacement is safe and dramatically cheaper.

The surgical approach can also affect facility and recovery costs. The direct anterior approach (operated from the front of the hip) typically results in shorter hospital stays and faster recovery than the traditional posterior approach, which may reduce your facility fee if it means a shorter length of stay. Ask your surgeon about both techniques and whether either is better suited to your anatomy and their experience.

5. Inpatient vs. outpatient status: a critical Medicare distinction

For Medicare patients, whether you are formally admitted as an inpatient or kept in observation status (outpatient) has dramatic cost implications—and you may not be told which status you are in unless you ask.

• Inpatient: Covered under Part A. You pay the deductible ($1,676 in 2026) and nothing further for the first 60 days. Implant and facility costs are bundled into the DRG rate.
• Observation / outpatient: Covered under Part B. You owe 20% coinsurance on the hospital’s outpatient charges, which are not DRG-bundled. A hip replacement billed as outpatient at a hospital could generate a 20% coinsurance obligation on $30,000+—meaning $6,000 or more out of pocket.
• Skilled nursing facility (SNF) qualification: Medicare covers up to 100 days in a skilled nursing facility after a qualifying inpatient stay of at least 3 days. If you are in observation status (even overnight), that time does not count toward the 3-day SNF qualification—meaning Medicare will not cover your post-acute rehabilitation stay.

Ask every day you are in the hospital: “Am I admitted as an inpatient or am I on observation status?” If you are on observation and expect a multi-day stay, ask your surgeon or hospitalist to change your status to inpatient if clinically justified. The Medicare Appeals Council has upheld observation status challenges in some cases.

6. CPT codes on your hip replacement bill

7. Common billing errors to look for

BillKarma identifies billing errors in 29% of hip replacement claims. The most frequent errors include:

• Implant upcoding: Billing for a premium ceramic-on-ceramic implant when a standard metal-on-polyethylene device was used. Ask your surgeon what specific implant was used and look up its model number in the operative report. The device billed should match what is documented in the surgical notes.
• Separately billing components included in the DRG: Under Medicare inpatient billing, the facility cannot bill separately for the implant device, operating room supplies, standard medications, or nursing care—these are all bundled into the DRG rate. Separate line items for these services on a Medicare inpatient claim are billing errors.
• Wrong DRG assignment: Assigning DRG 469 (with MCC) when the patient had no major complication or comorbidity, increasing the payment by several thousand dollars. Review the discharge summary to verify that the comorbidities listed actually meet the severity criteria for the higher DRG.
• Unbundled physical therapy: Physical therapy provided during the inpatient stay is included in the DRG facility payment. If you receive a separate PT bill for sessions provided while you were an inpatient at the same hospital, that is an unbundling error.
• Incorrect revision code: Billing 27134 (full revision) when only one component (acetabular cup or femoral stem) was revised, which would be coded 27137 or 27138 at a lower rate.

8. Questions to ask before surgery and action steps after

1. Confirm prior authorization was obtained. Before surgery, call your insurer and ask for the prior auth reference number for your procedure. Do not assume the surgeon’s office handled it.
2. Ask about the ASC option. If your surgeon operates at an ASC in addition to a hospital, ask whether you are a candidate for the outpatient setting. If your insurer covers ASC for THA and you are medically appropriate, the savings can be $10,000–$25,000.
3. Ask which approach (anterior vs. posterior) and what implant will be used. Note the implant brand and model in writing before surgery so you can verify the correct device was billed afterward.
4. Confirm inpatient admission status on day 1. If you are going to an inpatient hospital, ask the admitting staff to confirm your admission status is “inpatient” in writing.
5. Request the itemized bill and operative report after discharge. Both are available on request. Match each line item on the bill to the CPT codes and implant details documented in the operative report.
6. Check for separate implant billing. If you are a Medicare inpatient and your bill shows a separate implant line item, that is a DRG bundling violation. If you are a commercial patient, compare the implant device billed to your operative notes.
7. Dispute in writing. For any billing error found, send a written dispute to the facility’s billing department citing the specific CPT code, the documentation that contradicts the charge, and the Medicare rate. See our dispute guide for letter templates.
