Downside risk is no longer the edge of value-based care. It is the mainstream. In Performance Year 2026, the Medicare Shared Savings Program grew to 511 ACOs, and 82.8% of them now sit in two-sided risk arrangements where the organization is accountable for losses as well as savings, the highest share since the program began in 2012.[1] For clinical teams, that shift will feel like greater urgency around care gap closure, more pressure to document chronic conditions accurately and consistently, and more accountability for whether the patients attributed to the practice stay engaged and out of the emergency department.

The problem is that risk is signed at the executive level but produced at the front line. An organization can model benchmarks and risk corridors perfectly on paper and still lose money if the daily behaviors that drive quality, attribution, and avoidable utilization are not reliably happening in the exam room. Preparing frontline teams for downside risk is the part of readiness most organizations underinvest in, and it is the part that decides the result.

CMS finalized changes in the Calendar Year 2026 Physician Fee Schedule intended to move more ACOs into two-sided risk, and the Shared Savings Program now coordinates care for roughly 14.3 million Medicare beneficiaries.[1] The practical takeaway is direct: accepting accountability for losses is increasingly the price of admission to value-based care, and the organizations that perform under that accountability will be the ones whose frontline teams were prepared before the risk-bearing period began.

Two-sided risk has become the default, and the margin for unmanaged variation has narrowed

Under upside-only arrangements, a missed care gap was a missed opportunity. Under downside risk, the same miss can become a financial loss the organization has to absorb. The direction of travel is unmistakable, and it changes what readiness means for every role that reaches a patient. Whether a patient stays attributed to the practice, whether their chronic conditions are accurately captured and addressed over time, and whether avoidable admissions are prevented all depend on what frontline staff do consistently, visit after visit.

That is fundamentally a longitudinal care problem. Value-based care is built on continuous, whole-person management rather than isolated episodes, and downside risk simply raises the financial stakes of that continuity.[3] A patient who slips out of follow-up, whose chronic condition goes unmanaged between visits, or who ends up in the emergency department for something preventable is both a quality failure and a financial one. The front line is where that variation either gets controlled or does not.

The ACO REACH sunset compresses the timeline for teams that are not yet ready

For organizations in ACO REACH, the clock is even tighter. REACH concludes at the end of 2026, and its successor, the LEAD Model, launches January 1, 2027 as a long-term accountable care model.[2] Whatever path an organization chooses next, the runway to prepare frontline teams for sustained downside risk is measured in months, not years.

Transition planning tends to focus on contracts and actuarial structures, but the contract is not where risk is won or lost. The clinical reality is. An organization that moves into a new risk-bearing agreement without preparing the people who generate its outcomes is taking on accountability it has not yet built the capability to manage. Training takes time to land. Behaviors have to be defined, taught, practiced, and reinforced before they become reliable, which is exactly why preparation has to begin before the performance period, not during it.

Defining the behaviors that move the numbers gives frontline staff something concrete to act on

Telling a team to help the organization succeed under risk accomplishes nothing. Readiness comes from translating financial accountability into specific, role-based behaviors:

• Keeping attributed patients engaged in the practice
  Attribution in the Shared Savings Program is not a one-time assignment. It is earned and held through the ongoing care relationship, determined by where a patient receives the plurality of their primary care services across the year. When a patient disengages from the practice, misses follow-up visits, or drifts to outside providers for their primary care needs, the organization can lose that attribution and the shared savings potential that comes with it. Frontline staff, from the front desk managing scheduling to the care coordinator handling outreach, play a direct role in keeping that relationship intact. Understanding that patient engagement is not just a satisfaction goal but an attribution and financial one gives every touchpoint a clearer purpose. 

• Documenting chronic conditions accurately and consistently so the patient's complexity is reflected in their care plan
  Risk adjustment is designed to reflect how sick a population actually is, but it only works when clinical documentation captures that complexity accurately and consistently across the year. A patient whose chronic conditions are addressed at one visit and then left undocumented at the next is a patient whose true risk profile is invisible to the model. That gap understates the organization's attributed population complexity, weakens its benchmark, and ultimately undermines its financial position. Clinicians need to understand that documenting a chronic condition at every relevant encounter is not administrative repetition. It is the mechanism by which the care they are already providing gets properly credited. 

• Closing care gaps during the visit rather than deferring them, and following up after discharge to prevent a second admission.
  Under downside risk, a deferred care gap is no longer just a missed quality opportunity. It is a potential financial loss the organization absorbs directly. The same is true for a patient who leaves the hospital without a timely follow-up and returns to the emergency department within thirty days. Both outcomes are preventable, and both depend on frontline behaviors that have to be defined, practiced, and built into the workflow before the risk-bearing period begins. Rooming protocols that surface open gaps at the start of every visit, post-discharge follow-up ownership that is assigned rather than assumed, and escalation pathways for high-risk patients are not process improvements for their own sake. They are the specific behaviors that protect both the patient and the organization's performance under risk. 

Each of those is a teachable, observable behavior rather than an abstraction. When staff understand how their documentation and follow-through connect to attribution and shared savings, the financial model stops being someone else's spreadsheet and becomes a set of actions they can actually influence. Plain language talking points help the team explain a follow-up or a screening to patients in everyday terms, so the behaviors that protect both the patient and the organization happen naturally rather than feeling like compliance overhead.

Protecting capacity before adding accountability is a precondition for sustained performance

Asking a stretched team to carry more accountability without relieving anything is how readiness efforts fail. Excessive workload and administrative burden are recognized drivers of health worker burnout, and a downside-risk strategy that ignores those conditions risks worsening the workforce instability it depends on.[4] Credible preparation includes subtraction. Before layering on new expectations, leaders should identify what can be simplified, automated, or reassigned, so the behaviors that protect the organization financially are realistic to sustain rather than one more task on an overloaded day.

In each training scenario, the team should answer five questions: 

1. Who owns the next step?
   In high-functioning value-based care teams, accountability does not float. Every care gap, follow-up task, and post-discharge touchpoint needs a named owner before the patient leaves the building. When ownership is assumed rather than assigned, steps get missed, not because staff are careless, but because no one was explicitly responsible. Training should build the habit of closing every encounter with a clear handoff: who is doing what, by when, and how it will be confirmed. 

2. What information must be documented before the handoff is complete?
   A handoff without documentation is a gap waiting to happen. Under downside risk, incomplete information at the point of transition creates the conditions for both clinical harm and financial loss. Training must define the minimum documentation standard for each transition type so that the receiving party has what they need to act, and so the organization has the record it needs to demonstrate the care was delivered. 

3. What is the clinical risk if the step is missed?
   Frontline staff are more likely to follow through on a step when they understand what is at stake if they do not. When training connects the missed step to the clinical consequence, the behavior stops feeling like a compliance requirement and starts feeling like patient care. That shift in framing is what makes new workflows stick. 

4. What system or workflow supports the work?
   A behavior that depends on individual memory is not a reliable behavior. Training should walk staff through exactly where in the EHR, care management platform, or scheduling system each step lives, so that doing the right thing is the path of least resistance. If the system does not support the behavior, that is a workflow problem that needs to be solved before the risk-bearing period begins. 

5. What should be escalated rather than left for the next visit?
   Not every clinical situation can wait. Part of preparing frontline teams for downside risk is building clear escalation criteria so that high-risk patients and post-discharge warning signs are acted on immediately rather than added to a follow-up queue. Training should give every role a concrete answer: here is what you handle, here is what you escalate, and here is exactly how you do it. 

Conclusion: Build Frontline Readiness Before the Risk-Bearing Period Begins

Downside risk has become the standard form of value-based participation, and the organizations that thrive under it will not be the ones with the best actuarial models. They will be the ones whose frontline teams were prepared to produce the outcomes the model rewards.[1] Two-sided risk arrangements, compressed transition timelines, attribution accountability, care gap closure, avoidable utilization, and workforce capacity all show that teams need to understand how their daily behaviors affect the organization's financial performance before they are expected to deliver results under risk.
