Introduction To One Care Webinar 

MassHealth created this webinar to help One Care plans and their network providers understand the basics of One Care. On the webinar, Robin Callahan, MassHealth Deputy Medicaid Director for Policy and Programs, discusses the populations that are eligible for One Care, the enrollment process, services provided, and how the program will operate.


Massachusetts’ reform efforts include initiatives to develop patient-centered medical homes, bundled payments, accountable care organizations (ACOs), and pending state legislation to promote a multi-payer transition to the use of ACOs

Starting in 2013, approximately 110,000 dual eligibles in Massachusetts, ages 21-64 years who quality for both Medicaid and Medicare, will be included in a demonstration which will combine health care services and long-term supports and services (LTSS) into one integrated care organization (ICO). Individuals will be able to opt out if they want to remain with the present fee-for-service system. The ICOs will enter into three-way contracts with Medicare and Medicaid. They will receive an annual, blended capitated dollar amount for health care and LTSS per dual eligible. This demonstration, termed Duals, is intended to lower the rising costs of Medicaid and Medicare and improve health outcomes by coordinating care for this population.

MassHealth recently selected six organizations to act as Integrated Care Organizations (ICOs). A readiness review evaluates the ICO‘s ability to perform effectively. The ICOs include Blue Care (Blue Cross and Blue Shield of Massachusetts & Value Options); Boston Medical Center HealthNet Plan (BMCHP), Commonwealth Care Alliance (CCA), Fallon Total Care, LLC (FTC) – until 9/30/2015, Neighborhood Health Plan (NHP), and Network Health, LLC.(division of Tufts Health Care).

Integrated Care Organizations with Corresponding Service Regions

Each ICO covers a range of geographical areas in Massachusetts.
For quality oversight, MassHealth has recently announced several implementation activities:

  • Implementation Council, which will review progress and outcomes of demonstration and advise EOHHS.
  • Ombudsperson role; the ombudsperson will track and report complaints and issues to the ICO s(although independent of the ICO), ImpleOne Care Videos – Watch and hear members talk about why One Care works for them.mentation Council, and senior leadership
