ACO REACH Program Shift to LEAD: Why RPM and CCM Matter More Than Ever

Now CMS is building on those lessons. The Long-term Enhanced ACO Design (LEAD) model, launching January 1, 2027, extends the performance horizon to 10 years and fixes benchmarks for the full duration, creating a fundamentally different investment case for chronic care management infrastructure.

This post explains what the ACO REACH program is, how REACH compares to MSSP, what changes under LEAD, and why Remote Patient Monitoring (RPM) and Chronic Care Management (CCM) are the most direct operational tools available to ACOs navigating this transition.

What Is the ACO REACH Program?

The Accountable Care Organization Realizing Equity, Access, and Community Health (ACO REACH) program is a CMS Innovation Center model designed to shift providers from volume-based reimbursement to a model where payment is tied to patient outcomes, care quality, and cost efficiency.

To understand ACO REACH, it helps to start with the ACO meaning in healthcare. An Accountable Care Organization (ACO) is a network of physicians, hospitals, and other healthcare providers that voluntarily coordinates care for a defined patient population. Instead of each provider billing independently for individual services, ACO members share responsibility and financial risk for the total cost and quality of care delivered to their aligned beneficiaries.

What ACO REACH adds on top of the basic ACO model:

• A higher-risk reimbursement structure with capitated payment options
• A mandatory health equity focus, requiring participating ACOs to identify and address disparities in their patient populations
• Greater operational flexibility, ACOs can deploy innovative care tools and models that would not be reimbursable under standard fee-for-service
• Prospective beneficiary alignment, giving ACOs more certainty about their patient panel from the start of each performance year

Who Are ACO REACH Participants?

ACO REACH participation is open to several types of organizations, making it more inclusive than its predecessor models:

• Professional ACOs: Typically, physician-led groups taking on 50% shared savings and losses
• Global ACOs: Larger health systems and integrated delivery networks taking on 100% shared savings and losses
• High Needs Population ACOs: Organizations focused specifically on complex, high-cost Medicare beneficiaries with serious illness or disability
• New Entrant ACOs: Organizations new to CMS risk models that receive additional support during their first performance years

CMS publishes a list of ACO REACH participants annually. As of the most recent performance year, over 130 ACOs participate in the REACH model, collectively managing millions of Medicare beneficiaries.

How Does the ACO REACH Program Work?

ACO REACH structures reimbursement around two core financial levers: shared savings (when your ACO spends less than the CMS-calculated benchmark) and shared losses (when you spend more). The specific risk level depends on which track your ACO selects.

Risk and Reimbursement Tracks

The ACO REACH model offers two participation tracks based on how much financial risk an organization is ready to take on and how it wants to be reimbursed.

Professional Option

The Professional option is designed for physician-led ACOs that want meaningful upside opportunity without taking on full financial risk:

• 50% shared savings and 50% shared losses against the CMS benchmark
• Payment mechanism: Primary Care Capitation Payment (PCCP) a monthly, risk-adjusted flat fee covering all primary care services for aligned beneficiaries
• Better suited for smaller or newer ACOs building their value-based care capabilities

Global Option

The Global option is for mature health systems and integrated networks willing to accept full accountability:

• 100% shared savings and 100% shared losses
• Payment mechanism: PCCP or Total Care Capitation Payment (TCCP), a single capitated payment covering all Medicare-covered services for aligned beneficiaries
• Requires sophisticated care coordination infrastructure and population health analytics

How CMS Sets the Benchmark

CMS calculates a spending benchmark for each ACO based on a blend of the ACO's own historical spending and population-based benchmarks, adjusted for risk. If your ACO's actual spending falls below the benchmark, you receive a portion of the savings. If spending exceeds the benchmark, you owe a portion of the losses back to CMS.

This structure makes cost containment, particularly for high-utilization chronic patients, a direct financial priority. Every avoidable hospitalization or unnecessary ED visit that your care team prevents translates into shared savings.

At KangarooHealth, our connected care platform provides the RPM, CCM, and care coordination infrastructure ACOs need to manage chronic populations between visits and contain the utilization costs that drive benchmark overruns.

ACO REACH vs. MSSP: Key Differences

The Medicare Shared Savings Program (MSSP) is CMS's largest ACO program and the most common entry point for organizations new to value-based care. Understanding how ACO REACH differs from MSSP is critical when evaluating which model fits your organization's risk appetite and care delivery model.

The most important structural difference: MSSP allows ACOs to start with upside-only arrangements (no downside risk), while ACO REACH requires downside risk from day one. This higher risk exposure comes with greater reimbursement flexibility and the capitated payment options that make proactive chronic care management more financially rewarding under REACH.

ACO REACH Quality Measures

Financial performance in ACO REACH is not purely about cost. Quality scores gate your access to the full shared savings opportunity. ACOs must meet minimum quality thresholds to receive their full savings allocation. CMS updates the specific quality measure set periodically, but the core domains consistently reflect the program's emphasis on chronic disease management, preventive care, and patient experience.

The connection between quality measures and program design is intentional: the two quality areas with the most direct financial impact - unplanned admissions and readmissions are exactly where RPM and CCM deliver the most measurable results. ACOs that invest in connected care infrastructure don't just improve quality scores; they reduce the high-cost utilization events that most threaten benchmark performance.

Value-Based Care Cost Pressure: The Problem LEAD Solves

Here is the structural tension that has made it difficult for many ACOs to sustain and scale their REACH programs over time.

When your ACO successfully lowers healthcare utilization and reduces costs in one performance year, CMS uses that data to recalibrate your benchmark downward for future years. The better you perform, the harder it becomes to beat the next benchmark, a dynamic sometimes called the "ratchet effect." Your cost-reduction success today effectively becomes your performance hurdle tomorrow.

For practice managers and ACO administrators weighing long-term capital investments in staffing, technology platforms, or care management infrastructure, this benchmark volatility creates a real problem. The return horizon on those investments may not fit within a performance period where the goalposts keep moving.

This is the structural flaw LEAD is designed to fix.

LEAD Model Transition: What ACO REACH Participants Need to Know

CMS is transitioning from ACO REACH to the Long-term Enhanced ACO Design (LEAD) model, which launches January 1, 2027, and runs through December 31, 2036. The transition reflects CMS's intent to preserve what worked in REACH while solving the investment horizon and benchmark volatility problems.

What the Fixed Benchmark Means Operationally

The single most significant change in LEAD is the elimination of rebasing. Under LEAD, the spending benchmark is set at the start of the model period and locked in for the full 10 years. Once your ACO lowers spending below that fixed benchmark, the gap stays in your favor year after year, for a decade.

This changes the investment calculus entirely. A connected care platform or expanded care coordination team that costs money to implement in Year 1 but reduces hospitalizations by 15% in Year 2 continues generating compounding shared savings through Year 10. Under ACO REACH's 4-year window and periodic rebasing, that same investment might not reach payback before the benchmark shifts again.

Non-Primary Care Capitation (NPCC)

LEAD also introduces Non-Primary Care Capitation (NPCC), a mechanism that makes it easier for ACOs to bring specialists into risk arrangements. For ACOs managing patients with complex, multi-specialty conditions, heart failure, advanced CKD, oncology, NPCC creates a financial pathway for specialist coordination that did not exist cleanly within REACH's structure.

This matters for connected care: as specialists join ACO risk arrangements, care coordination across settings becomes more financially critical, and the care management workflows that CCM enables become more valuable across the care team.

The Current Transition Timeline

ACO REACH will complete its final performance year in December 2026. Current REACH participants who meet LEAD's eligibility criteria may apply to transition directly into the LEAD model beginning January 2027. CMS has indicated its intention to provide a clear pathway for eligible REACH participants, though application requirements and transition timelines will be published closer to the deadline.

Why RPM and CCM Are the Right Operational Response

ACO REACH and LEAD both reward the same behavior: keep patients healthier, reduce avoidable utilization, and deliver high-quality coordinated care. Remote Patient Monitoring (RPM) and Chronic Care Management (CCM) are the programs most directly designed to achieve those outcomes, and they carry their own Medicare billing pathways, making them revenue-generating investments on top of their ACO value.

Remote Patient Monitoring (RPM)

RPM enables continuous, passive monitoring of patient health data between in-person visits, using connected devices that automatically transmit readings to your care platform. For the chronic conditions that drive the most ACO utilization costs, RPM provides the early warning system that makes proactive intervention possible. Learn more about remote patient monitoring and how it works within a value-based care model.

RPM for Diabetes

Continuous glucose monitors (CGMs) and connected glucometers transmit blood sugar readings in real time. Care coordinators can identify patterns indicating poor control, adjust medication titration protocols remotely, and intervene before hyperglycemic or hypoglycemic episodes require emergency care. Directly supports the HbA1c quality measure that ACOs are scored on.

RPM for Hypertension

Wi-Fi or cellular-enabled blood pressure cuffs generate daily readings without requiring clinic visits. Your team monitors trends, flags outliers, and intervenes early when a patient's blood pressure trajectory indicates a cardiovascular event risk. This directly reduces the unplanned admissions that most threaten ACO benchmark performance.

RPM for Heart Failure and COPD

Daily weight monitoring (a proxy for fluid retention) and pulse oximetry allow early detection of decompensation in heart failure and COPD patients, 2 of the highest-cost readmission drivers in Medicare. Early intervention through RPM-triggered outreach can prevent hospitalizations that cost multiples of what an entire year of monitoring costs.

Chronic Care Management (CCM)

CCM is a Medicare benefit that reimburses non-face-to-face care coordination services for patients with 2 or more chronic conditions, exactly the population at the center of ACO financial risk. Where RPM provides continuous monitoring, CCM provides continuous coordination. For a detailed look at how these two programs work together, see: Chronic Care Management and Remote Patient Monitoring.

CCM's core value for ACOs:

• Comprehensive electronic care plans that travel with patients across specialists and care settings, reducing duplication and care gaps
• Medication reconciliation and adherence coaching, particularly high-value for patients on complex multi-drug regimens
• Care transitions management- post-discharge follow-up that directly reduces the 30-day readmissions tracked in ACO quality scoring
• 24/7 access to a care team member- reducing the unnecessary ED visits that occur when patients don't know where else to turn

The benefits of chronic care management for ACOs extend well beyond the patient outcomes from improved quality scores to new monthly billing revenue.

The Dual Revenue Advantage

A critical feature that separates RPM and CCM from other ACO cost-containment strategies: they carry independent Medicare billing pathways. CCM (CPT 99490, 99439, 99491, 99437) and RPM (CPT 99454, 99457, 99458) generate monthly fee-for-service reimbursement on top of any shared savings the ACO earns.

For an ACO managing 500 patients in CCM and 400 in RPM, the incremental monthly billing revenue can be substantial - revenue generated while simultaneously reducing the utilization that eats into benchmark performance. It is one of the few strategies in value-based care where the intervention pays for itself directly.

Under LEAD's 10-year fixed benchmark, deploying RPM and CCM infrastructure in 2027 creates a compounding return: shared savings widen year over year while monthly billing revenue accrues across a growing patient panel.

Frequently Asked Questions About ACO REACH (FAQs)

The following FAQs clarify what ACO REACH means, how it compares to MSSP, who can participate, and what providers should know as the model transitions toward LEAD.

What does ACO REACH stand for?

ACO REACH stands for Accountable Care Organization Realizing Equity, Access, and Community Health. The name reflects CMS's intent to go beyond pure cost efficiency and explicitly address health disparities within the Medicare population.

How does ACO REACH differ from MSSP?

The primary differences are risk level, payment mechanism, and operational flexibility. MSSP allows upside-only arrangements with no downside risk (in its Basic tracks), while ACO REACH requires downside risk from the start, either 50% (Professional) or 100% (Global). In return, REACH offers capitated payment options (PCCP and TCCP) and greater freedom to deploy non-traditional care tools. See the full comparison table in Section 3.

What quality measures does ACO REACH use?

ACO REACH quality measures span five domains: chronic disease management (HbA1c control, blood pressure control), preventive care (fall risk screening), patient experience (CAHPS surveys), and utilization (all-cause unplanned admissions, hospital readmissions). Quality performance gates access to the full shared savings allocation, making it inseparable from the financial success of the program.

Who are the ACO REACH participants?

Participants include Professional ACOs (typically physician-led), Global ACOs (health systems and integrated networks), High Needs Population ACOs (focused on complex Medicare beneficiaries), and New Entrant ACOs. CMS publishes an annual list of ACO REACH participants on its Innovation Center website. As of the most recent performance period, more than 130 ACOs participate in the REACH model.

Can a small independent practice participate in an ACO?

Yes. Small independent practices frequently participate in ACOs, either by joining an existing ACO network or forming one with other local providers. Participating in an ACO gives smaller practices access to care coordination infrastructure, population health analytics, and shared savings opportunities that would be difficult to develop independently. Contact KangarooHealth to learn how our platform supports practices of all sizes.

What happens to current ACO REACH participants during the LEAD transition?

ACO REACH concludes at the end of the 2026 performance year. Participants who meet LEAD's eligibility requirements will have an opportunity to apply for and transition into the LEAD model starting January 1, 2027. CMS is expected to publish detailed eligibility and application guidance ahead of the transition. For more on how KangarooHealth supports CMS model transitions, see: How KangarooHealth Powers Connected Care for CMS Models.

Can an ACO use both RPM and CCM simultaneously?

Yes. RPM and CCM address complementary aspects of chronic care - RPM provides continuous biometric monitoring, while CCM provides structured care coordination and care planning. Patients who qualify for both can be enrolled in both programs concurrently. For a full overview of how the two programs work together, see: Chronic Care Management and Remote Patient Monitoring. Each carries its own Medicare billing pathway, and KangarooHealth maintains separate time tracking and documentation for each to ensure compliance.

Conclusion

The shift from ACO REACH to LEAD is not just a program transition; it is a structural signal from CMS that long-term investment in chronic care management infrastructure is the right bet. A fixed 10-year benchmark with no rebasing and no minimum savings rate means that every dollar you save through better care coordination stays in your column for the remainder of the performance period.

RPM and CCM are the most direct operational tools for capturing those savings: they reduce the hospitalizations and ED visits that eat into benchmark performance, improve the quality measures that gate shared savings access, and generate independent monthly billing revenue while doing it. Under LEAD's investment horizon, deploying this infrastructure early doesn't just make clinical sense; it makes compelling financial sense.

KangarooHealth provides the connected care platform, clinical team, and CMS-compliant workflows ACOs need to execute that strategy at scale from the first enrolled patient to a panel of thousands. Explore our RPM services and CCM and PCM programs to see what's possible.
