In a significant shift toward value-based care and digital health integration, the Centers for Medicare & Medicaid Services (CMS) has announced a major expansion of its flagship initiative, the Advancing Chronic Care with Effective, Scalable Solutions (ACCESS) model. Starting in the spring of 2027, the program—which aims to revolutionize how chronic conditions are managed within traditional Medicare—will incorporate four critical new health tracks, effectively broadening the reach of the initiative to cover approximately 75% of all Medicare beneficiaries.
The expansion marks a pivotal moment in the 10-year trajectory of the CMS Innovation Center’s test program, signaling a firm commitment to moving away from episodic, fee-for-service medicine toward a model defined by continuous, technology-enabled, and outcome-based care.
The Core Mandate: What is the ACCESS Model?
Launched in July 2025, the ACCESS model was engineered to address the systemic inefficiencies inherent in the traditional Medicare fee-for-service payment structure. Under standard arrangements, providers are often compensated for individual procedures or visits, a model that frequently discourages long-term monitoring and preventive intervention.
ACCESS (Advancing Chronic Care with Effective, Scalable Solutions) flips this script. It empowers healthcare providers to utilize digital tools, telehealth services, and multidisciplinary care teams that were previously ineligible for standard reimbursement. By doing so, CMS incentivizes providers to take full responsibility for the total cost of care and the quality of patient outcomes. Under this arrangement, the 160 participating organizations currently enrolled in the model can earn a share of the savings if they demonstrate improvements in health outcomes while simultaneously reducing overall expenditures.
The program is fundamentally a 10-year sandbox designed to determine if outcome-based financial incentives can successfully bridge the gap between traditional medicine and the modern, connected digital health landscape.
Expansion Details: Addressing the Burden of Chronic Disease
The upcoming expansion scheduled for spring 2027 represents the most substantial update to the program since its inception. By adding heart failure, chronic obstructive pulmonary disease (COPD), substance use disorders (SUD), and tobacco cessation to the existing tracks of high blood pressure and diabetes, CMS is directly targeting the primary drivers of Medicare spending and mortality.
The Four New Tracks
- Heart Failure: A chronic condition requiring meticulous management to prevent costly hospital readmissions.
- COPD: Focused on respiratory health and proactive, remote monitoring.
- Substance Use Disorders (SUD): This track is particularly comprehensive, covering opioid and alcohol use disorders while explicitly including support for co-occurring mental health conditions like depression and anxiety.
- Tobacco Cessation: A preventive initiative aimed at reducing the long-term systemic impact of nicotine addiction on cardiac and pulmonary health.
Notably, the SUD track is closely aligned with the Trump administration’s "Great American Recovery" initiative, highlighting the intersection of federal policy and public health intervention. Furthermore, CMS has announced the extension of its musculoskeletal pain track, allowing patients who have exhausted their initial 12-month care window to receive ongoing, long-term support—a recognition that chronic pain management rarely adheres to a one-year timeline.
Chronology: From Concept to National Scalability
The evolution of the ACCESS model is a study in the gradual adoption of healthcare technology by federal regulators.
- July 2025: The ACCESS model officially launches. The initial phase focuses on foundational chronic conditions, primarily high blood pressure and diabetes, setting the stage for a new era of digital health integration.
- Late 2025 – 2026: CMS monitors the performance of the initial 160 provider organizations. Data begins to emerge regarding the efficacy of remote monitoring and virtual care in reducing hospitalizations.
- Early 2027: CMS announces the formal expansion, incorporating heart failure, COPD, SUD, and tobacco cessation into the model’s framework.
- Spring 2027: The official rollout of the expanded tracks begins, with new cohorts expected to onboard throughout the year.
- 2027–2035: The ongoing evaluation phase, during which CMS will continuously assess whether the model is meeting its goals of cost containment and patient quality improvement.
CMS has maintained an open-door policy for the program, confirming that it will continue to accept new participating organizations on a rolling basis throughout the remainder of its 10-year mandate.
Official Commentary: Dr. Mehmet Oz on the Future of Care
CMS Administrator Dr. Mehmet Oz heralded the expansion as a critical step in modernizing the Medicare system. In a statement released on Tuesday, Dr. Oz emphasized the necessity of integrating advanced technologies into the standard clinical workflow.
"ACCESS is one of the tools we are using to bring healthcare into the digital age," Dr. Oz stated. "It gives patients and their providers greater access to AI-enabled technologies, remote monitoring, connected devices, and other innovative tools that can help identify problems earlier and improve care. This latest expansion of the program will help more Americans get the care they need and reward providers who deliver actual results."
The emphasis on "AI-enabled technologies" and "connected devices" underscores the agency’s belief that the future of medicine is not merely human-centric, but augmented by data-driven insights. By incentivizing the adoption of these tools, CMS is essentially forcing a digital transformation upon the provider community, rewarding those who can successfully leverage data to prevent health crises before they result in emergency department visits.
Implications for the Healthcare Ecosystem
For Providers: A Shift in Business Models
The transition to an ACCESS-aligned model requires a significant cultural and operational shift for healthcare systems. Providers must move from a volume-based mindset to a value-based one. This requires investing in data infrastructure, hiring care coordinators, and becoming comfortable with risk-sharing arrangements. While the potential for shared savings is lucrative, the financial risk of failing to meet outcome targets is a substantial hurdle for smaller or rural practices.
For Patients: A More Cohesive Experience
For the average Medicare beneficiary, the expansion promises a more proactive approach to their health. Rather than waiting for a scheduled appointment to address a symptom, a patient in an ACCESS-participating practice may benefit from continuous monitoring. For example, a patient with heart failure might have a connected scale and blood pressure cuff that transmits data directly to their care team, allowing for medication adjustments before a cardiac event occurs.
For Technology Vendors: A Market Opportunity
The expansion creates a robust marketplace for digital health companies. Developers of remote patient monitoring (RPM) platforms, AI-driven diagnostic tools, and digital therapeutics now have a clear path to integration. As providers seek to meet the quality benchmarks set by the ACCESS model, their demand for reliable, scalable, and user-friendly technology will likely skyrocket.
Challenges and Limitations
Despite the optimism surrounding the announcement, the model faces significant challenges. The most prominent limitation is the exclusion of Medicare Advantage (MA) enrollees. Because the ACCESS model is currently restricted to traditional Medicare beneficiaries, a massive segment of the population—those enrolled in private MA plans—remains outside the scope of this particular experiment.
Furthermore, critics have long argued that "digital health" is not a panacea. The success of the program will depend heavily on the digital literacy of the elderly population. If the tools provided are too complex or if the "connected" nature of the care leads to alarm fatigue among clinicians, the expected outcome improvements may fail to materialize.
Finally, there is the question of the "digital divide." As CMS pushes for more technology-enabled care, there is a risk that rural or low-income populations—who may lack reliable internet access or the devices required for remote monitoring—could be left behind, potentially widening health disparities despite the program’s intended goal of increasing access.
Looking Ahead
The 2027 expansion of the ACCESS model is a bold, high-stakes gamble on the power of technology to improve public health. As the new cohorts begin their work next year, the healthcare industry will be watching closely. Will the program lead to genuine improvements in chronic disease management, or will it merely serve as a vehicle for broader digital tool adoption with marginal impacts on long-term clinical outcomes?
The next phase of the 10-year test will provide the data necessary to answer these questions. If the model succeeds, it may serve as the foundational blueprint for a total overhaul of the Medicare payment system, permanently altering the relationship between providers, patients, and the technology that sustains them. For now, the medical community remains cautiously optimistic, awaiting the tangible results that only time and patient participation can provide.
