The CMS LEAD Model Starts in January. You’re Going to Have to Run It.
As organizations accepted into the CMS LEAD model enter their implementation period before performance Year 1 begins January 1, 2027, there’s only about three months to finish building networks, configure systems and train staff.
Most of the coverage so far has focused on benchmarks and payment tracks. Far less has been said about the people who will actually have to make this work, and for a lot of participants, that’s where the real exposure sits.
A model built for newcomers
The CMS LEAD model replaces ACO REACH and runs through 2036, making it the longest ACO test CMS has ever attempted. The design choices point in a clear direction. CMS wants organizations that have stayed out of value-based care to finally step in. The model explicitly targets providers new to ACOs, including smaller, independent and rural-based practices, and it offers a 1.5% add-on payment to ACOs whose baseline spending runs above their regional average, a group that often includes high-need and rural providers.
That’s good news for community hospitals and independent groups that have watched ACOs from the sidelines. It also means a wave of organizations is about to take on two-sided risk without anyone on staff who has done it before.
The leadership gap
Running an ACO is its own discipline. Someone has to understand how patients get attributed, read claims data well enough to spot where spending leaks out, and persuade physicians to change referral habits they’ve had for fifteen years. That person also has to report to a board that may not fully understand what it signed up for.
In practice, this is rarely one job. Most ACOs that perform well have an operational leader who owns the contracts, data and reporting, paired with a physician leader who can walk into a department meeting and get colleagues to take the work seriously. The physician half of that pairing is often the harder hire. Clinicians who have credibility with peers, experience managing to a cost target and any interest in administrative work make up a very short list.
People with this background exist, but most of them are already spoken for. CMS made continuity for current ACO REACH organizations a central goal of the LEAD design, so the leaders running those ACOs today have every reason to stay put. First-time participants will be competing for a small pool of talent, on a short timeline, often from locations that are hard to recruit into under the best circumstances.
A rural health system can’t afford to spend the first six months of a ten-year model searching for the executive who should have been in place on day one.
Ten years changes the turnover math
The feature getting the most attention is the benchmark. LEAD sets a ten-year performance period with no rebasing, so improvements can compound without being penalized. For finance leaders, that stability is the main attraction.
It also raises the stakes on who stays.
Under shorter models, losing a primary care physician hurt for a year and then washed out. In a decade-long arrangement, that departure has a longer tail. The physician who leaves in year two takes years of trust with them. Some of their patients follow them out of the network. Others stop scheduling preventive visits and resurface in the emergency department. The care management work that was supposed to pay off in years four and five gets restarted with a new clinician and a skeptical patient panel.
APPs matter just as much here, since they carry a growing share of primary care panels, especially in rural clinics. So do the care coordinators, community health workers and home-based teams LEAD leans on to serve patients eligible for both Medicare and Medicaid and those who are homebound or home limited. Many organizations will need to hire several of these roles at once, in the same few months, while their HR teams are already stretched filling nursing and physician openings.
These positions were hard to fill before LEAD. Now each vacancy chips away at results the organization is counting on for the next decade.
Specialists enter the picture
LEAD also asks more of specialists than earlier models did. Through CMS-administered risk arrangements, CMS will run voluntary, episode-based risk arrangements between ACOs and specialists, and a new sub-capitation option lets an ACO pay a specialty group a fixed monthly amount for its patients’ care.
For well-staffed urban systems, that opens new partnership options. For a rural ACO with one cardiologist covering three counties, it raises a harder question about whether the specialist capacity exists at all. When that single cardiologist takes leave or retires, the ACO loses more than visit volume. It loses the partner it was counting on to manage those episodes.
What boards and executives should be doing now
Start with ownership. If no single leader is accountable for LEAD performance by January, that’s the first problem to solve. For organizations still searching, an interim executive with value-based care experience can carry the first performance year and build the infrastructure a permanent leader will inherit. That approach also takes pressure off the permanent search. A board choosing a ten-year leader under a deadline tends to settle, and a retained search run without that deadline usually produces a better fit.
Look hard at who carries your attributed patients. Pull the list of physicians and APPs with the largest panels and ask some uncomfortable questions. Who is within a few years of retirement? Who has been open about burnout? Who is the only provider covering a clinic or service line? Those are the names that determine whether your ACO performs, and they deserve succession plans as much as any executive does.
Build coverage plans before you need them. A locum tenens physician or PRN clinician who can step into a panel quickly keeps patients connected to the practice while a permanent search runs. The organizations that handle this well line up coverage relationships in advance. Scrambling after a resignation letter lands usually means weeks of cancelled appointments, and in a LEAD ACO, those are attributed patients drifting elsewhere.
Treat care team hiring as a project, with its own plan and capacity. Filling a dozen care coordination and population health roles in one quarter is a different undertaking than filling them one at a time over two years. If internal recruiters are already at capacity, that work needs a dedicated team, internal or external, with a clear owner and timeline.
Bring retention into the boardroom. If the board is tracking shared savings, it should also be tracking provider turnover in the practices driving those savings. They are the same number, reported on different timelines.
Where outside support fits
Few organizations entering LEAD will have every piece of this in-house, and they shouldn’t try to. The ones that do well will know which gaps to fill themselves and which to hand to partners who do this work every day. At Optigy, that tends to look like interim leaders who keep a new ACO moving while a permanent search runs, physician and executive searches built for rural and community settings, and locum and PRN coverage that holds panels together through transitions.
Driving down risk
Most LEAD participants will spend the next three months on data feeds, network contracts and technology setup. Those things matter. But the organizations that struggle in 2029 probably won’t trace it back to a software problem. They’ll find a leadership seat that stayed empty too long and a primary care bench that thinned out one departure at a time.
