EMDEON AND WEBMD ANNOUNCE EXPECTED TIMING FOR PROVIDING 2007 FINANCIAL GUIDANCE

ELMWOOD PARK, N.J. and NEW YORK, N.Y., October 20, 2006 — Emdeon Corporation (Nasdaq: HLTH) and its 85.6% owned subsidiary, WebMD Health Corp. (Nasdaq: WBMD) today announced the expected timing for providing the companies’ 2007 financial guidance.

As a result of the previously announced pending transaction regarding the Emdeon Business Services segment, Emdeon does not intend to provide its financial guidance for 2007 until early 2007. WebMD will provide its financial guidance for 2007 on November 2, 2006, when it reports its results for the quarter ended September 30, 2006. WebMD expects that its financial guidance for 2007, taking into account the May 2007 expiration of its existing agreement with the AOL division of Time Warner (“AOL”), will be within the range of existing published analyst estimates.

Under the AOL Agreement, which was entered into in May 2001 and expires on May 1, 2007, WebMD provides healthcare content, tools and services for use on certain AOL properties. WebMD does not expect its existing agreement with AOL to continue following the expiration of that agreement. The page view traffic from AOL was less than 5% of the aggregate WebMD Health Network page view traffic for the quarter ended June 30, 2006. As a result of the expiration in May 2007, the page view traffic from AOL will no longer be part of the WebMD Health Network. Additionally, revenues and earnings of approximately $5 million per year related to certain contractual guarantees will also end with the expiration of the Agreement.

As previously announced, Emdeon and WebMD will release their respective financial results for the three months ended September 30, 2006 at approximately 4:00 pm (ET) on Thursday, November 2, 2006. The Companies will host a conference call at 4:45 pm (ET) on that day to discuss those results. Investors can access the call via webcast at www.emdeon.com (in the About Emdeon section) or at www.wbmd.com (in the Investor Relations section) at that time. A replay of the call will be available at the same web addresses.
