The Centers for Medicare & Medicaid Services (CMS) has officially announced a significant expansion of its Advancing Chronic Care with Effective, Scalable Solutions (ACCESS) model, a move designed to integrate modern digital health tools and value-based payment structures into the management of some of the most prevalent and costly chronic conditions facing the American elderly population. Beginning in the spring of 2027, the ACCESS model will incorporate four new clinical tracks—heart failure, chronic obstructive pulmonary disease (COPD), substance use disorders (SUD), and tobacco cessation—marking a pivotal shift in how traditional Medicare approaches long-term disease management. This expansion follows the initial launch of the program in July, which focused primarily on high blood pressure and diabetes, and it signals a broader federal commitment to transitioning away from episodic, fee-for-service care toward a continuous, technology-enabled healthcare delivery system.
The ACCESS model serves as a centerpiece of the CMS Innovation Center’s (CMMI) ten-year strategic plan to evaluate whether outcome-based payments can effectively incentivize providers to adopt remote monitoring, artificial intelligence (AI) diagnostics, and non-traditional care teams. By including heart failure and COPD, CMS is targeting two of the primary drivers of hospital readmissions among seniors. Furthermore, the inclusion of substance use disorder and tobacco cessation tracks reflects a growing recognition of the behavioral health crisis within the Medicare demographic, aligning the program with the broader goals of the Great American Recovery initiative. With this latest expansion, CMS estimates that approximately 75% of all traditional Medicare beneficiaries will qualify for at least one of the clinical tracks under the ACCESS model, representing a massive scaling of digital health intervention.
The Evolution and Mechanism of the ACCESS Model
The ACCESS model was established as a decade-long experimental framework to test the viability of scalable, tech-driven solutions in the public payer space. Unlike traditional Medicare, which often operates on a rigid fee-for-service (FFS) schedule that reimburses for specific office visits or procedures, the ACCESS model allows for a more fluid use of resources. Participating providers—which currently number approximately 160 organizations—are granted the flexibility to utilize digital tools, remote patient monitoring (RPM) devices, and health coaches that are not typically covered under standard Medicare reimbursement rules.
In exchange for this flexibility, providers assume a higher degree of financial and clinical responsibility. The model utilizes a shared savings structure where organizations are rewarded if they successfully improve patient outcomes and reduce the total cost of care over a specified period. This shift is intended to encourage "continuous engagement" rather than the "episodic" nature of traditional medicine, where a patient might only see a physician after a health crisis has already occurred. By utilizing connected devices—such as digital scales for heart failure patients or pulse oximeters for those with COPD—care teams can identify physiological red flags in real-time, allowing for early intervention that prevents emergency room visits.
Detailed Breakdown of the New Clinical Tracks
The expansion scheduled for 2027 introduces tracks that address high-acuity and high-cost conditions. Each new track has been designed to address specific gaps in the current Medicare landscape:
Heart Failure and COPD Management
Heart failure is currently a leading cause of hospitalization for Americans aged 65 and older, often resulting in a "revolving door" of readmissions that are both costly for the taxpayer and detrimental to the patient’s quality of life. The ACCESS track for heart failure will focus on daily monitoring of weight and fluid retention, enabling providers to adjust medications remotely. Similarly, the COPD track aims to reduce exacerbations by monitoring lung function and oxygen levels, providing patients with immediate digital access to respiratory therapists and specialized care teams.
Substance Use Disorder and Tobacco Cessation
The SUD track is perhaps the most significant policy shift within the expansion. It is designed to provide comprehensive support for opioid and alcohol use disorders, which have seen a steady rise among the elderly. Notably, this track will also address co-occurring mental health conditions such as depression and anxiety. CMS has explicitly tied this track to the Great American Recovery initiative, a federal effort to combat the addiction crisis through increased access to treatment and recovery resources. The tobacco cessation track further emphasizes prevention, acknowledging that long-term smoking remains a primary contributor to the severity of both heart and lung diseases.
Musculoskeletal (MSK) Pain Extension
In addition to the four new tracks, CMS is extending the duration of its existing musculoskeletal pain track. Previously, support for patients with chronic pain was limited to a 12-month care period. Under the new guidelines, beneficiaries with qualifying conditions can continue to receive technology-enabled support and specialized physical therapy interventions beyond the initial year, recognizing that chronic pain management is often a multi-year or lifelong requirement.
Chronology of the ACCESS Model Development
The trajectory of the ACCESS model reflects a multi-year effort to modernize the Medicare infrastructure. The following timeline outlines the key milestones of the program:
- January 2024: CMS identifies the need for a scalable model to bridge the gap between traditional Medicare and the digital health capabilities seen in the private sector.
- July 2024: The ACCESS model officially launches with 160 participating organizations. The initial focus is restricted to hypertension (high blood pressure) and Type 2 diabetes.
- Late 2024 – Early 2025: Initial data from the first cohorts suggest improved patient engagement through the use of mobile health apps and remote monitoring.
- February 2025: CMS Administrator Mehmet Oz announces the expansion of the program, introducing the Spring 2027 start date for the four new tracks.
- 2025–2026: CMS begins a rolling recruitment process for new healthcare organizations, including health systems, physician groups, and tech-enabled clinics, to prepare for the 2027 rollout.
- Spring 2027: The heart failure, COPD, SUD, and tobacco cessation tracks go live for all participating providers.
Supporting Data and Economic Context
The decision to expand the ACCESS model is rooted in the staggering economic burden of chronic disease. According to data from the Centers for Disease Control and Prevention (CDC), chronic diseases account for roughly 90% of the nation’s $4.5 trillion in annual healthcare expenditures. Within the Medicare population, the costs are even more concentrated; beneficiaries with five or more chronic conditions account for a disproportionate share of total spending.
By targeting heart failure and COPD, CMS is addressing conditions that have historically high per-capita costs. For instance, the average cost of a single heart failure-related hospitalization can exceed $14,000. If the ACCESS model can reduce readmission rates by even 10% through remote monitoring and AI-enabled triage, the savings to the Medicare Trust Fund could reach billions of dollars over the ten-year test period.
Furthermore, the "Great American Recovery" focus on substance use disorders addresses a demographic reality: from 2000 to 2020, the rate of overdose deaths among seniors aged 65 and older increased significantly. By folding SUD treatment into a primary care-aligned model like ACCESS, CMS hopes to destigmatize treatment and improve long-term recovery rates for older adults.
Official Responses and Industry Reactions
The expansion has drawn significant attention from healthcare leadership and policy experts. CMS Administrator Mehmet Oz emphasized the technological necessity of the move during the agency’s announcement.
"ACCESS is one of the tools we are using to bring healthcare into the digital age, giving 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," Oz stated. "This latest expansion of the program will help more Americans get the care they need and reward providers who deliver actual results."
Industry stakeholders, including digital health companies and primary care associations, have generally welcomed the expansion. Many proponents argue that traditional Medicare has lagged behind Medicare Advantage (MA) in offering "supplemental" digital benefits. By bringing these tools to traditional Medicare, CMS is narrowing the "digital divide" between the two programs. However, some critics remain cautious, noting that the success of the model depends heavily on the "digital literacy" of the elderly population and the ability of rural providers to access high-speed internet required for connected device functionality.
Broader Impact and Future Implications
The expansion of the ACCESS model represents a significant milestone in the federal government’s transition toward value-based care. By the time the new tracks are implemented in 2027, the program will likely serve as the primary blueprint for how CMS intends to handle the "Silver Tsunami"—the aging of the Baby Boomer generation.
One of the most critical implications of this expansion is the potential for AI in clinical decision support. The ACCESS model encourages the use of AI to analyze data streams from remote devices. For a COPD patient, an AI algorithm might detect subtle changes in breathing patterns days before the patient feels symptomatic, prompting a nurse to intervene. This "proactive" rather than "reactive" stance is the ultimate goal of the 10-year CMMI test.
However, the program remains exclusive to traditional Medicare beneficiaries. Those enrolled in Medicare Advantage plans—which currently make up about half of the Medicare population—are not eligible for the ACCESS model, as MA plans already have their own private-sector incentives for cost-saving and digital tool integration. This distinction creates a two-tiered system of innovation that CMS will eventually need to reconcile if the ACCESS model proves successful.
As the 2027 rollout approaches, the healthcare industry will be watching closely to see if the expanded tracks can deliver on the promise of "actual results." If the ACCESS model succeeds in lowering the cost of care for heart failure and COPD while effectively addressing the SUD crisis, it may move from a "10-year test" to a permanent fixture of the American healthcare landscape, fundamentally changing the relationship between the government, the provider, and the patient.
