On January 1, 2026, CMS flipped the switch on the Transforming Episode Accountability Model (TEAM), the most aggressive mandatory bundled payment program since BPCI Advanced. Approximately 741 acute care hospitals in 188 Core-Based Statistical Areas (CBSAs) are now required to take financial accountability for five surgical episodes from admission through 30 days post-discharge.
The five episodes: lower extremity joint replacement (LEJR), surgical hip femur fracture treatment (SHFFT), spinal fusion, coronary artery bypass graft (CABG), and major bowel procedures.
This is not a voluntary pilot. It is not a demonstration. Every IPPS hospital in a selected CBSA is in, whether they wanted to be or not. And for ACOs operating in those same markets, the downstream effects are massive.
I have started six ACOs and helped generate over $300 million in shared savings. And I can tell you from firsthand experience: surgical episode costs are one of the most undermanaged cost categories in the MSSP. TEAM changes that, whether ACOs are ready or not.
Under TEAM, participating hospitals receive a target price that covers all Medicare costs associated with the surgical episode, including the inpatient stay, post-acute care (skilled nursing facility stays, home health), physician follow-up visits, and any readmissions within 30 days. If total episode costs come in below the target price, the hospital earns a reconciliation payment. If costs exceed the target, the hospital owes CMS money back.
The model runs for five performance years through December 31, 2030. Quality performance adjustments factor into the final reconciliation amounts, meaning hospitals that score poorly on quality metrics see their potential upside reduced and their downside exposure increased.
Here is the critical detail for ACOs: CMS has explicitly designed TEAM to overlap with both MSSP and ACO REACH. A beneficiary can be attributed to an ACO and simultaneously trigger a TEAM episode at a participating hospital. CMS will not adjust the ACO's benchmark or the hospital's target price to account for the overlap.
That means both entities have independent financial incentives to reduce the total cost of the surgical episode. In theory, this should drive collaboration. In practice, it creates a coordination problem that most ACOs and hospitals are not equipped to solve.
Let me walk through the math. Say your ACO has 25,000 attributed beneficiaries, and 15% of them are in a CBSA with a TEAM-participating hospital. That is 3,750 beneficiaries whose surgical episodes are now subject to dual financial accountability. If even 8% of those beneficiaries undergo one of the five TEAM procedures in a given year, you are looking at 300 surgical episodes where both the hospital and your ACO have skin in the game.
The average Medicare spend on a lower extremity joint replacement episode is roughly $26,000 to $32,000. For CABG, it can exceed $55,000. For major bowel procedures, $40,000 to $50,000. If your ACO's care coordination does not extend into surgical episode management, you are leaving significant cost reduction on the table while the hospital captures the upside through TEAM reconciliation.
Here is where it gets worse. Early analyses from Brandeis University and the Institute for Accountable Care project that up to two-thirds of participating hospitals will lose revenue under TEAM, averaging $1,350 in lost revenue per case. Hospitals under financial pressure will look for ways to cut costs, and that often means shorter inpatient stays and faster discharges to lower-cost post-acute settings. Without ACO-level oversight, those decisions can lead to higher readmission rates, which directly inflate your ACO's total cost of care.
This is the surgical cost trap: the hospital optimizes for the episode target price, the ACO eats the readmission cost, and nobody coordinates the post-acute transition.
LEJR has the longest track record in bundled payments, dating back to CJR. Most hospitals have already optimized length of stay and shifted toward outpatient total joint replacements. The ACO risk here is primarily in post-acute care utilization. If your beneficiaries are being discharged to SNFs instead of home with home health, you are overpaying by $8,000 to $12,000 per episode. AI-driven post-acute placement optimization is the single highest-ROI intervention for LEJR episodes.
Hip fractures are a different animal. These patients are older, frailer, and have significantly higher 30-day mortality and readmission rates. The average episode cost is $35,000 to $45,000, and post-acute care represents 40% to 50% of total spend. For ACOs, the key lever is ensuring timely surgical intervention (within 24 to 48 hours of admission) and structured post-discharge follow-up. Every day of delayed surgery increases mortality risk by 5% to 7%.
Spinal fusion episodes have the widest cost variation of any TEAM procedure, ranging from $20,000 to $60,000 depending on the number of levels fused, surgical approach, and implant costs. The ACO opportunity is in upstream utilization management. Many spinal fusions are elective, and evidence shows that 20% to 30% of lumbar fusions do not meet clinical appropriateness criteria. Pre-surgical review and conservative treatment pathways can reduce unnecessary procedures while improving patient outcomes.
CABG is the highest-acuity procedure in TEAM, with average episode costs exceeding $55,000. Readmission rates for CABG hover around 12% to 15% nationally. Post-discharge complications, including surgical site infections, arrhythmias, and heart failure exacerbations, drive the majority of avoidable readmissions. ACOs need real-time post-discharge monitoring and rapid clinical escalation pathways to keep CABG episodes on track.
Major bowel procedures carry the highest complication rates of the five TEAM episodes, with surgical site infection rates of 10% to 15% and 30-day readmission rates approaching 15% to 20%. Post-operative ileus, anastomotic leaks, and sepsis are the primary cost drivers. For ACOs, the intervention point is post-discharge monitoring with early detection of complications before they escalate to emergency department visits or readmissions.
The fundamental problem with surgical episode management is that it requires coordination across entities that do not share data, do not share incentives, and do not share workflows. The surgeon, the hospital, the SNF, the home health agency, the PCP, and the ACO are all operating in parallel with limited visibility into each other's actions.
This is exactly the kind of problem that multi-agent AI systems are designed to solve.
At Zynix, we deploy specialized AI agents that each handle a distinct piece of the surgical episode workflow:
At PBACO, we deployed multi-agent workflows that reduced post-acute spend by over 30% on orthopedic surgical episodes. At Union Health, our AI agents identified $2.1 million in avoidable surgical episode costs within the first two quarters by flagging inappropriate SNF placements and coordinating earlier home health transitions.
If your ACO operates in any of the 188 CBSAs where TEAM is active, here is your immediate action plan:
Identify which of your attributed beneficiaries are likely to receive care at TEAM-participating hospitals. Cross-reference your beneficiary panel with CMS's published list of TEAM participants. Quantify the number of expected surgical episodes by procedure type.
Approach your TEAM-participating hospitals with a shared savings alignment proposal. Both parties benefit from lower episode costs. The ACO brings care coordination infrastructure and post-acute management. The hospital brings surgical quality improvement and inpatient cost control. Formalize this with a data-sharing agreement and joint care protocols.
Post-acute care is the single largest cost lever in four of the five TEAM episodes. You need real-time visibility into where your beneficiaries are being discharged, whether those placements are clinically appropriate, and how post-acute costs compare to benchmarks. If you are still relying on claims data with a 90-day lag, you are managing surgical episodes with a rearview mirror.
The 48-hour and 7-day post-discharge windows are where readmissions are either prevented or allowed to happen. Manual call center models cannot scale across 300 or more surgical episodes per year. Multi-agent AI systems can execute structured post-discharge outreach, process patient responses, escalate concerns to clinical staff, and document everything in the care management platform without human bottlenecks.
Do not wait for annual reconciliation to find out whether your surgical episodes were profitable. Build or deploy prospective episode cost tracking that integrates hospital discharge data, post-acute claims, and pharmacy data to project episode costs in near-real-time.
TEAM is not just a hospital problem. For ACOs with beneficiaries in the 188 mandatory markets, surgical episode costs are now a shared accountability. The ACOs that build surgical episode management capabilities, whether through hospital partnerships, post-acute optimization, or multi-agent AI deployment, will capture significant savings. The ACOs that ignore TEAM will watch their total cost of care inflate as hospitals make unilateral decisions to optimize their own target prices.
The $300 million in shared savings I have helped generate across six ACOs did not come from ignoring the details. It came from building systems that manage every cost category with precision. Surgical episodes are the next frontier. TEAM just made it mandatory.
