Issue Statement
The High Needs model was designed to provide high-quality, coordinated care for Medicare’s most complex and vulnerable patients. Originally part of the Global and Professional Direct Contracting model launched under the Trump Administration and now part of ACO Realizing Equity Access and Community Health (REACH),the model is currently set to expire in 2026. Given the promising early signals that it is improving outcomes and reducing costs for high need patients, it is critical that the Centers for Medicare & Medicaid Services (CMS) and the Innovation Center take swift action to ensure that patients have continued access to high-needs focused accountable care beyond 2026.
Accountable care models are essential for high needs patients because they enable the pro-active, team-based care that is impossible to deliver under a fee-for-service payment system. To support high need beneficiaries and their specialized care providers, accountable models must include flexibilities and design elements that are tailored to the unique needs and characteristics of these patients.
Results Show Cost Savings and Improved Care
The High Needs ACO program has already demonstrated promising impacts on utilization and cost. A recent evaluation showed gross savings of 3.5% and reduced emergency department visits and hospitalizations.
