ACO Enablers and Primary Care Aggregators

The ACO Enablers and Primary Care Aggregators category focuses on organizations that help healthcare providers transition to and thrive in value-based care models. These entities play a crucial role in supporting primary care practices and health systems by enabling participation in Medicare programs, including the Shared Savings Program (MSSP) and ACO REACH, as well as Medicare Advantage and commercial value-based contracts. Their services include care coordination, chronic disease management, and administrative support to streamline participation in these programs.

A primary function of these enablers is to provide technology platforms that integrate data, deliver point-of-care insights, and offer population health analytics to identify care gaps and manage patient outcomes. Additionally, they assist with financial management, compliance, and regulatory reporting to ensure sustainable operations under risk-bearing models. By offering care management teams and strategies for patient engagement, these organizations foster better adherence to care plans and promote healthier patient behaviors. Through aggregation and risk-sharing models, ACO enablers empower providers to deliver high-quality, coordinated care while improving financial performance under value-based care contracts.
