The health system, its volumes, prices and projections are composites written for a model paper; federal rules, data and research come from the sources listed.

At the planning meeting for the system's proposed same-day joint program, the chief financial officer asked the question everyone was thinking: why would the system build a program that takes knee and hip replacements away from its own main hospital, where they earn more? The director of strategy and marketing answered that the patients would leave either way; the question was whether they would leave for the system's surgery center or for a competitor's. This paper explains the opportunity, sizes it and tests whether the system should pursue it.

The Change That Created the Opportunity

For years, Medicare treated total knee replacement as an inpatient procedure. Rules in recent years removed it from the inpatient-only list and, for 2020, added it to the list of procedures Medicare covers when performed in ambulatory surgery centers, alongside changes to outpatient and surgery center payment (Centers for Medicare & Medicaid Services, 2019). Hip replacement followed. Advances in anesthesia, pain control and rapid recovery protocols made same-day discharge safe for many carefully selected patients, and surgeons gained experience with it quickly.

National Trends

The shift is well under way. Federal payment advisers found that surgery center volume for traditional Medicare patients grew in 2024 partly because of increases of 27.6% in knee replacements and 28.7% in hip replacements; for most services, Medicare's surgery center rates were about 46% lower than hospital outpatient rates (Medicare Payment Advisory Commission, 2026). Commercial insurers and self-insured employers have moved in the same direction, often with stronger incentives.

Why Patients Move

Demand for joint replacement is rising with an aging population; projections based on Medicare data put annual primary knee replacements among Medicare patients at about 1.2 million by 2040 (Shichman et al., 2023). Many patients also prefer going home the same day. The first paper found that patients in the system's market valued same-day discharge and recovery support, while the second found that working adults and active retirees fit outpatient surgery well.

Sizing the Local Opportunity

The metropolitan market performs roughly 4,100 hip and knee operations each year. Clinical criteria suggest that about 45% of patients are suitable candidates for same-day surgery, about 1,850 cases. The system currently performs 1,300 joint replacements a year, all in its hospitals, about 32% of the market. A physician-owned surgery center across town began outpatient joint replacement last year and performs about 300 cases a year.

Competition

The competing center has advantages: surgeon owners, lower overhead and a head start. Its disadvantages include limited capacity, no hospital backup on site and no relationships with the region's largest employer. Two national companies that partner with surgeons to open centers have approached orthopedic groups in the region, raising the chance of another competitor within two years.

Cannibalization

The system's outpatient program would draw mostly from its own hospital cases. Of its first-year projected 520 outpatient cases, about 400 would otherwise have been done in its hospitals, and 120 would be new to the system. Each hospital case moved to the surgery center earns less revenue: roughly $6,000 less per Medicare case and more for some commercial contracts. Cannibalizing your own revenue is painful; watching a competitor do it for you is worse.

The Counterfactual

The key question is not whether the program earns less per case than the hospital did but how the system compares with and without it. Without the program, the analysis estimated that the system would lose about 250 of its hospital joint cases a year to competitors within three years, as surgeons and payers moved cases to lower-cost sites. With the program, the system keeps most of those cases and gains new ones from the employer contract and growth.

A Five-Year Model

The model assumes 520 outpatient cases in year one, rising to 900 in year five; average payment of $17,500 per case across payers; direct cost of $12,900 per case, including implants, which are the largest single cost; and $1.8 million in one-time costs for equipment and program launch. The program reaches a positive cumulative contribution in year three. Freed hospital operating room time is reused for more complex procedures that remain inpatient.

Commoditization Risk

As outpatient joint replacement becomes routine, it risks becoming a commodity purchased mainly on price, especially by employers and insurers. The system's defense is quality and coordination: outcome reporting, a hospital backup for complications and smooth, rehearsed transfer to inpatient care when needed.

The Employer Opportunity

The region's largest employer offers a separate opening. Self-insured employers pay commercial prices, often far above Medicare's, and many now contract directly with providers for fixed-price bundles covering surgery, implants, anesthesia and follow-up. The system proposed a bundle for outpatient knee and hip replacement with a guarantee that treatment of specified complications arising within three months would carry no added charge. For the employer, the bundle offers predictable costs and faster return to work; for the system, it offers volume and a relationship that competitors lack.

Surgeons as Partners

No outpatient program works without surgeons. The system's orthopedic group had two concerns: loss of control over scheduling and the competing center's ownership opportunity. The director proposed a co-management agreement in which surgeons help set protocols and share in quality-based incentives, structured within federal rules on physician payments. Surgeons would also gain predictable operating room blocks, which the busy main hospital could not offer.

Sensitivity of the Model

The director tested the model's assumptions. If volume reached only 70% of projections, the program would reach positive cumulative contribution in year four rather than three. If implant costs fell by only half of the targeted amount, margin per case would drop by about $600. If both occurred, the program would still break even over five years but with little room for error. These scenarios shaped the conditions below.

Conditions for Going Ahead

The director recommended pursuing the opportunity with four conditions: orthopedic surgeons must commit to moving suitable cases; implant contracts must be renegotiated to reduce per-case cost; patient selection criteria must be clinical and consistent; and outcomes must be reported quarterly to the board.

Risks

The main risks are lower-than-expected volume if surgeons stay with the competing center, higher costs if implant prices do not fall and complications that damage reputation. Each has a measure and a trigger for review: fewer than 400 cases in year one, per-case cost above $13,500 or any rise in 90-day complications above the hospital's rate would bring the program back to the board.

Conclusion

A federal payment change opened joint replacement to surgery centers, and national data show volume moving quickly at lower prices. The system's outpatient program would take cases from its own hospitals, but competitors would take more if it did nothing. Sized with local data, tested with a five-year model and bounded by conditions, the opportunity is worth pursuing on the system's own terms.
