Emdeon Closes Acquisition of Altegra Health

Acquisition brings together Altegra Health’s cloud-based, risk adjustment and quality analytics platform and related healthcare consumer engagement capabilities with Emdeon’s Intelligent Healthcare Network™ to help customers elevate care quality, optimize financial performance and improve the member and patient experience

NASHVILLE, Tenn. (August 13, 2015) – Emdeon Inc. today announced that it has closed its previously announced acquisition of Altegra Health, a national provider of technology and intervention platforms that combine data aggregation and analytics with unique member engagement and reporting capabilities to achieve actionable insights and improved management for value-based healthcare. The acquisition combines Altegra Health’s risk adjustment and quality analytics platform with Emdeon’s Intelligent Healthcare Network™, revenue cycle technology and payment solutions, enabling the delivery of innovative products designed to help customers elevate care quality, optimize financial performance and improve the member and patient experience.

With this acquisition, Emdeon is better positioned to support healthcare organizations as they navigate unprecedented marketplace disruption, including the growth in Medicare Advantage, Managed Medicaid, exchange-based insurance markets and the transition to value-based care models. The combination of the two companies is expected to strengthen the existing capabilities of both organizations and create new, innovative platforms that will address the opportunities and challenges created by the evolution of a more dynamic healthcare marketplace and regulatory landscape.

As the single largest financial and administrative network in the United States healthcare system, Emdeon’s Intelligent Healthcare Network reaches 750,000 physicians, 105,000 dentists, 60,000 pharmacies, 5,000 hospitals, 600 vendors, 450 laboratories and 1,200 government and commercial payers and processed approximately 8.1 billion transactions in 2014.

“We are thrilled to welcome Altegra Health to Emdeon,” said Neil de Crescenzo, president and chief executive officer for Emdeon. “The powerful combination of our people and solutions will allow us to further leverage our Intelligent Healthcare Network, as we expand our customer relationships and help them thrive in the world of value-based healthcare. Altegra Health has created leading end-to-end solutions that provide health plans and other risk-bearing organizations with the data, insights and related services they need to expertly manage care, ensure appropriate reimbursement and engage individuals in improving their use of the healthcare system. Together, we can bring tremendous value to the markets, organizations and individuals we serve.”

“This is an exciting time for organizations focused on delivering measurable value to a rapidly evolving healthcare marketplace,” said Kevin Barrett, who joins Emdeon as executive vice president and president of Altegra Health. “Being part of Emdeon allows us to continue our growth as a leading provider of quality measurement and risk analytics, revenue management and eligibility and enrollment solutions to health plans and other risk-bearing organizations, as well as expand into emerging areas important to our customers.”
