FOR IMMEDIATE RELEASE

Emdeon to Acquire Chamberlin Edmonds to Expand its Technology-
Enabled Services Platform in the Hospital Market

NASHVILLE, Tenn. (September 7, 2010) — Emdeon Inc. (NYSE: EM), a leading provider of healthcare revenue and payment cycle management solutions, today announced it has entered into a definitive agreement to acquire Chamberlin Edmonds & Associates, Inc., a leading provider of government program eligibility and enrollment services to over 200 acute care facilities in 30 states. Chamberlin Edmonds’ technology-enabled services assist hospitals in lowering the incidence of uncompensated care, reducing bad-debt expense and increasing overall cash flow.

Emdeon will acquire Chamberlin Edmonds, a privately held company, for $260 million in cash. The transaction will be financed through the use of unrestricted cash and borrowings under an amendment to Emdeon’s existing credit facility that will be established simultaneously with the closing of the transaction. In connection with the credit facility amendment, Emdeon has entered into an incremental $100 million financing commitment with Citigroup Global Markets Inc.

Headquartered in Atlanta, Georgia, Chamberlin Edmonds has a 24-year track record of patient advocacy and guiding uninsured patients through the complex processes associated with securing reimbursement from Medicaid, Social Security Disability, state disability, charity care and other community benefit programs. Chamberlin Edmonds’ service model includes highly-trained professionals, such as staff nurses, trained social services personnel and government program specialists, that are located on-site at a hospital and collaborate closely with the hospital’s revenue cycle team. To support its on-site healthcare representatives, Chamberlin Edmonds utilizes its regional resolution centers and centralized back office infrastructure to deliver cost-efficient and comprehensive eligibility services from initial patient referral through the post-application resolution process.

“The acquisition of Chamberlin Edmonds continues Emdeon’s strategic expansion into technology-enabled services that drive meaningful value for our customers and make healthcare more efficient,” said George Lazenby, chief executive officer for Emdeon. “As government programs continue to expand under healthcare reform, hospitals will need better tools to lower the rate of uncompensated care and increase cash flows. The combined company will be able to offer enhanced revenue cycle services designed to help providers navigate the complex systems related to government reimbursement.”

According to the Congressional Budget Office, healthcare reform is expected to result in Medicaid volumes growing from 39 to 55 million eligible individuals by 2014. These Medicaid volume increases will likely impact providers because the amount of uncompensated care provided to low income or unemployed patients is greatly affected by the amount of state Medicaid funding. By integrating Emdeon’s revenue cycle management solutions with Chamberlin Edmonds’ technology-enabled enrollment services, providers will have an enhanced platform to assist patients in applying for financial assistance programs and increase the likelihood of receiving payments for services provided to those patients.

“Chamberlin Edmonds has created a scalable technology-enabled service delivery platform that blends national reach and perspective with local delivery and knowledge,” said T. Ulrich Brechbühl, president and chief executive officer for Chamberlin Edmonds & Associates. “By joining Emdeon, we are significantly better

positioned to offer the full suite of tools, technologies, services and expertise required to build an optimized eligibility process, from screening through enrollment and cash recovery, to hospitals nationwide.”

For the six-months ended June 30, 2010, Chamberlin Edmonds’ revenue was approximately $46.3 million. The acquisition is subject to customary closing conditions, including expiration or early termination of the waiting period under the Hart-Scott-Rodino Act, and is expected to close in the fourth quarter of 2010.
