EMDEON ANNOUNCES PRELIMINARY FIRST QUARTER RESULTS

EMDEON ANNOUNCES INCREASE IN FULL YEAR 2006 FINANCIAL GUIDANCE

ELMWOOD PARK, NJ (April 18, 2006) — Emdeon Corporation (NASDAQ: HLTH) today announced preliminary financial results for the quarter ended March 31, 2006 and an increase in its 2006 financial guidance.

“Due to a variety of recent factors, we expect to report stronger than anticipated first quarter results and with this in mind are increasing our full year expectations,” said Kevin Cameron, Chief Executive Officer of Emdeon. “We are completing our normal closing process and expect to provide more detail on May 4, 2006, our previously scheduled earnings release date.”

Preliminary Results for Three Months Ended March 31, 2006
Emdeon expects that it will report the following financial results for the first quarter of 2006:

• Revenue of $338 million to $339 million, compared to prior guidance of $328 million to $338 million and compared to $304 million in the prior year period.

• Earnings before interest, taxes, non-cash and other items (“Adjusted EBITDA”) of $0.18 per share, compared to prior guidance of $0.14 to $0.15 per share and compared to $0.12 per share in the prior year period.

• Net income of $0.05 to $0.06 per share, compared to prior guidance of $0.02 to $0.03 per share and compared to $0.03 per share in the prior year period.

Key factors impacting the preliminary results are described below. Some of these items impacted the mix of revenue in a manner that disproportionately impacted Adjusted EBITDA and net income. These factors include:

• Stronger than anticipated medical claims volume at Emdeon Business Services resulting in part from the renegotiation of a number of customer agreements during the first quarter and increased compliance by submitters with respect to certain pre-existing agreements.

• Stronger than anticipated volume in our remittance and payment services at Emdeon Business Services due to volume ramping up faster than expected with respect to certain new customer implementations.

• Stronger than anticipated growth in sales of direct-to-provider revenue cycle management solutions at Emdeon Business Services resulting in part from improvements made to the sales and implementation processes.

• Stronger than anticipated software sales at ViPS.

• Stronger than anticipated gross margins on system sales at Emdeon Practice Services.

• Lower than anticipated expenses at Emdeon Business Services, Emdeon Practice Services and Corporate resulting primarily from greater than expected operating efficiencies and cost savings as well as the shift of certain planned expenses to future periods.

• Revenue and Adjusted EBITDA for Emdeon’s WebMD Health subsidiary are anticipated to be at or slightly above the high end of its previously issued financial guidance range.

Emdeon Increases 2006 Financial Guidance
As a result of the favorable trends experienced in the first quarter and increased customer interest in certain new products at Emdeon Business Services, Emdeon is increasing its financial guidance for the twelve months ending December 31, 2006. Emdeon expects:

• Revenue of $1.380 billion to $1.430 billion, compared to prior guidance of $1.365 billion to $1.415 billion and compared to $1.277 billion in the prior year period.

• Adjusted EBITDA of $225 million to $255 million, compared to prior guidance of $200 million to $230 million and compared to $184 million in the prior year period.

• Net income of $70 million to $90 million, compared to prior guidance of $45 million to $65 million and compared to $73 million in the prior year period. The current year guidance reflects incremental non-cash stock-based compensation expense of $43 million to $45 million related to the January 1, 2006 adoption of SFAS 123R, when compared to the prior year period.

Attached to this press release are schedules that outline Emdeon’s preliminary first quarter financial results and updated 2006 financial guidance and include reconciliations between GAAP and non-GAAP financial measures used in this release.
