Fallon Total Care

Selected to Provide Integrated Health Care to Dual Eligible Medicare and Medicaid Residents in Massachusetts

The joint venture between Fallon Community Health Plan and Magellan Health Services will serve individuals in 10 counties across the state.

Worcester, Mass., November 5, 2012—Fallon Total Care™, the joint venture between Fallon Community Health Plan (FCHP) and Magellan Health Services (NASDAQ: MGLN), has been selected to participate in a new, three-year demonstration program to provide integrated health care to individuals aged 21 to 64 years who are eligible for both Medicare and Medicaid. Participation in the program will allow Fallon Total Care to serve dual-eligible residents in 10 counties across Massachusetts: Barnstable, Bristol, Essex, Hampden, Hampshire, Middlesex, Norfolk, Plymouth, Suffolk and Worcester.

Fallon Total Care integrates Magellan’s expertise in behavioral health services and FCHP’s physical health capabilities and clinical experience to create an entirely new and transformative model of care specific to this population.

“Fallon Community Health Plan is very pleased to partner with Magellan to create Fallon Total Care, and to work together to support the unique health care needs of this important and vulnerable population,” said Richard Burke, FCHP’s President of Senior Care Services and Government Programs and Chairman of Fallon Total Care’s board of managers. “For FCHP, one of the first health plans in the country to provide coverage to Medicare beneficiaries and the nation’s top NCQA-ranked Medicaid health plan for five of the past six years, this opportunity further supports our mission and our unwavering commitment to increasing and improving access to quality-based, affordable health care.”

“We welcome the opportunity to bring our experience and innovation to the people of Massachusetts,” said Scott Markovich, Magellan’s senior vice president for Medicaid strategy.  “As one of the largest providers of behavioral health services for Medicaid members nationally,

we’ve been at the forefront of serving this population, many of whom are dual eligibles. We understand the importance of moving beyond the traditional care management system to integrate both medical and behavioral health care. Our goal in partnering with Fallon Community Health Plan is to fundamentally change how health care is delivered so that we can improve the quality and outcomes of this population. This is a transformational event for Magellan as we move aggressively from developing a Medicaid strategy for the future to implementing Fallon Total Care’s unique model of care to specific states.”

Massachusetts will be one of the first states in the nation to launch a dual-eligible demonstration program being offered by the Centers for Medicare & Medicaid’s Federal Coordinated Health Care Office. The goal of the contract awards, subject to completion of readiness review and contract negotiation, is to provide enrollees with comprehensive, integrated services that address their full range of medical and behavioral health needs. Dual-eligible adults under the age of 65 typically have complex care needs—they may be disabled and often have serious mental illnesses.

FCHP’s Medicaid ranking is according to the National Committee for Quality Assurance’s Health Insurance Plan Rankings 2012-13. NCQA is a private, non-profit organization dedicated to improving health care quality.
