Bundled payments are a healthcare payment model where a single price covers all the services, treatments, and supplies related to a specific medical episode, rather than billing separately for every blood test, doctor’s visit, and procedure. If you’re getting a hip replacement, for example, a bundled payment would wrap the surgery, hospital stay, anesthesia, physical therapy, and follow-up care into one combined price. The goal is to encourage providers to coordinate care and control costs instead of piling on services.
How Traditional Billing Works Differently
Under the traditional fee-for-service system, every provider involved in your care sends a separate bill for each individual service. The surgeon bills for the operation, the hospital bills for the room, the anesthesiologist bills separately, and the physical therapist sends yet another invoice. Each provider gets paid more when they do more, regardless of whether those extra services actually improve your outcome.
Bundled payments flip that incentive. Because there’s a fixed target price for the entire episode of care, providers share responsibility for keeping total costs within that budget. If they deliver quality care for less than the target price, they keep the savings. If costs run over, they may owe money back. This creates a financial reason for your surgeon, hospital, and rehab team to actually talk to each other and avoid unnecessary steps.
Two Ways Bundled Payments Work
Bundled payments come in two forms: retrospective and prospective. Both set a target price for an episode of care, but they differ in when the money changes hands.
With a retrospective approach, providers initially bill for each service the traditional way. After the episode ends, the total spending is compared against the target price. If the total came in under budget, providers receive a bonus payment. If it exceeded the target, they owe the difference back. This is how the largest current Medicare bundled payment program (BPCI Advanced) operates.
With a prospective approach, a designated provider (usually a hospital) receives a single lump-sum payment upfront. That provider then distributes the money among all the clinicians and facilities involved in the episode. Any savings compared to the target price stay with the providers, and any overruns come out of their pockets.
What Counts as an “Episode of Care”
An episode of care is a defined window of time surrounding a specific condition or procedure. It typically starts when you’re admitted for surgery or diagnosed with a condition and extends through your recovery, often 30 to 90 days after discharge. Everything that happens in that window, including complications, readmissions, and post-acute care like rehab, can be included in the bundle.
The conditions and procedures commonly covered by bundled payments span a wide range. Under the current Medicare BPCI Advanced model, 34 clinical episode categories fall into eight groups:
- Orthopedics: hip and knee replacements, spinal fusion, femur and hip fractures
- Cardiac procedures: bypass surgery, valve replacement, pacemaker and defibrillator implantation, stent procedures
- Cardiac care: heart failure, heart attack, cardiac arrhythmia
- Spinal procedures: back and neck surgeries, spinal fusion
- Gastrointestinal: bariatric surgery, major bowel procedures, GI bleeding, inflammatory bowel disease
- Neurological care: stroke, seizures
- Medical and critical care: pneumonia, sepsis, COPD, kidney failure, urinary tract infections, cellulitis
Joint replacements and cardiac procedures were among the earliest and most common bundled payment episodes because they’re high-volume, expensive, and follow relatively predictable recovery paths.
Financial Risk for Providers
The financial stakes for providers depend on the structure of the arrangement. In a one-sided (upside-only) model, providers can earn bonuses for spending below the target price but don’t owe anything if they go over. This is a lower-risk entry point.
In a two-sided model, providers face both the possibility of bonuses and the possibility of losses. The current BPCI Advanced program requires all participants to accept downside financial risk from the start, meaning hospitals and physician groups can owe money back to Medicare if their episode costs exceed the target. This stronger accountability is where the model gets its teeth. Providers who consistently run over budget have a real financial incentive to redesign how they deliver care.
What the Evidence Shows
Research on bundled payments shows meaningful but not dramatic savings. A 2025 study in JAMA Health Forum found that participation in a bundled payment program for outpatient spine surgery was associated with nearly 10% lower total episode spending, translating to about $1,200 less per episode. The same study found that hospitals in the BPCI Advanced model saw a 2.2 percentage-point reduction in 90-day return hospital admissions.
Earlier programs showed more modest results, partly because they didn’t always include post-acute care in the bundle. The Medicare Acute Care Episode Demonstration, which ran from 2009 to 2012, saved an average of $585 per episode on hospital and physician costs. But because post-acute care wasn’t included in that bundle, spending on rehab and skilled nursing actually increased, shrinking the net savings to $319 per episode. That experience taught program designers an important lesson: bundles work best when they capture the full arc of recovery, not just the hospital stay.
What This Means for Patients
For patients, the most tangible benefit of bundled payments is better coordination. When all providers share a financial stake in your outcome, they’re more likely to plan your discharge carefully, ensure your follow-up appointments happen, and catch complications early rather than waiting for a costly readmission. Programs like Geisinger’s ProvenCare, which bundled everything from preoperative evaluation through 90 days of post-surgical care including cardiac rehabilitation and readmissions, demonstrated that wrapping services together improves the care experience.
Bundled payments also increase price transparency. Instead of receiving a cascade of unpredictable bills from multiple providers over several months, a bundled model creates a single, more predictable cost for the whole episode. Early bundled payment programs for cardiovascular care showed that patients received high-quality care with little or no out-of-pocket expense while also gaining increased access to care. That said, your individual cost-sharing still depends on your insurance plan’s specific rules.
Where Bundled Payments Are Headed
Medicare is expanding bundled payments with a new mandatory model called TEAM (Transforming Episode Accountability Model), set to run from January 2026 through December 2030. Unlike voluntary programs where hospitals opt in, TEAM will require participation from acute care hospitals in selected geographic areas across the country. It covers five surgical procedures: lower extremity joint replacement, surgical hip fracture treatment, spinal fusion, coronary artery bypass graft, and major bowel procedures. The care episode extends from surgery through 30 days post-hospitalization.
The shift from voluntary to mandatory participation signals that Medicare views bundled payments as a proven enough model to scale nationally, not just test with willing hospitals. For patients in the affected regions, this means their surgical care will increasingly be delivered under a system designed to reward efficiency and coordination rather than volume.
