CMS’s New Joint Replacement Bundle Could Squeeze Skilled Nursing Revenue — and Nobody Knows by How Much

Washington, D.C. — A new federal payment model that would hold hospitals financially accountable for every hip and knee replacement — from the operating room through 90 days of recovery — has skilled nursing operators asking a question CMS hasn’t fully answered: how much of the projected savings comes out of their revenue?

The Centers for Medicare and Medicaid Services tucked the Comprehensive Care for Joint Replacement Expanded Model, or CJR-X, into its proposed FY 2027 hospital payment rule, published in April 2026. The model would be mandatory for virtually all eligible acute-care hospitals nationwide, with Performance Year 1 set to begin October 1, 2027.

CMS estimates the model would save Medicare roughly $725 million over five years. That sounds like a win for taxpayers. But it raises an uncomfortable question for every skilled nursing facility in the country: who actually absorbs those savings?

How the Bundle Works

Under CJR-X, hospitals are accountable for the total cost of care during a 90-day window that starts at the moment of surgery. Everything falls inside that window — the inpatient stay, physical therapy, home health visits, durable medical equipment, outpatient follow-ups, and yes, skilled nursing facility stays.

When the episode wraps up, CMS compares actual spending to a risk-adjusted benchmark. If the hospital came in under target, it pockets a share of the difference. If costs ran over, it writes a check back to Medicare.

That structure creates a straightforward financial incentive: keep post-acute costs down. And post-acute care — particularly skilled nursing — is one of the most significant cost drivers in a joint replacement episode. A week in a skilled nursing facility can run several thousand dollars. A hospital under a spending target has every reason to push patients toward shorter SNF stays, home health instead of SNF, or outpatient rehab.

The Unanswered Question

The industry is watching carefully, because it’s been here before. The original CJR model ran from 2016 to 2024 across 67 metropolitan areas. Skilled nursing providers saw real pressure during that period as hospitals pushed patients toward lower-cost discharge settings. CJR-X doesn’t just expand the geography — it removes the geographic limits entirely. Every eligible hospital in the country would participate.

The model would also, for the first time, cover outpatient joint replacements alongside inpatient ones. As more of these surgeries shift to ambulatory surgical centers — a trend driven by both clinical advances and insurer incentives — CJR-X closes a gap that would otherwise let hospitals sidestep accountability by moving cases to the outpatient setting.

Industry groups haven’t issued formal responses yet, but the unease is palpable. Operators who have navigated recent shifts in how hospitals and skilled nursing facilities coordinate post-acute care know that bundled payment models change the relationship dynamic in real ways. A hospital with a financial stake in a patient’s 90-day trajectory isn’t a neutral referral source anymore.

What’s Next

The proposed rule is open for public comment through June 9, 2026. That’s the window for skilled nursing providers and industry associations to make their case to CMS — on everything from how benchmarks are calculated to whether the model adequately accounts for the complexity of patients who genuinely need skilled nursing care after surgery.

CJR-X won’t take effect until October 2027 at the earliest, and it’s still a proposed rule. But for skilled nursing operators, the direction of travel is clear. The question isn’t whether hospitals will have new incentives to reduce SNF utilization. They will. The question is whether CMS builds in enough guardrails so that patients who actually need skilled nursing still get it — and whether providers get paid fairly when they deliver it.
