WEBMD REPORTS SECOND QUARTER RESULTS

REVENUE, INCOME BEFORE TAXES, NON-CASH AND OTHER ITEMS AND NET INCOME
IN LINE WITH COMPANY GUIDANCE AND ANALYSTS’ CONSENSUS ESTIMATES

WEBMD CORPORATION TO BE RENAMED EMDEON CORPORATION

ELMWOOD PARK, NJ (August 4, 2005) — WebMD Corporation (NASDAQ: HLTH) today announced financial results for the three months ended June 30, 2005.

WebMD Corporation Now Operating As Emdeon Corporation

In a separate release issued today, WebMD Corporation announced that it is now operating under the name Emdeon Corporation. Emdeon’s ticker symbol will remain HLTH. WebMD Corporation is changing its corporate name in order to avoid confusion with its subsidiary, WebMD Health, which is expected to trade separately on NASDAQ under the symbol WBMD following its planned initial public offering of 10% to 14% of its equity. The Company made this decision because the WebMD name is more closely associated with WebMD Health and its Web sites than with its other businesses.

The Company’s segments will be known as Emdeon Business Services, Emdeon Practice Services, WebMD Health and Porex. The implementation of operational and branding use of the name Emdeon will begin immediately. At the Annual Meeting of Stockholders to be held on September 29, 2005, the Company will seek approval of an amendment to its Certificate of Incorporation to change its legal name from WebMD Corporation to Emdeon Corporation.

Kevin Cameron, Chief Executive Officer of Emdeon Corporation, stated: “While our name is changing, our mission and goals remain the same. We intend to continue to work, on behalf of our payer, vendor and provider customers, to improve both the financial and clinical aspects of healthcare delivery. At the core of our vision is the commitment to connect providers, payers, employers, physicians and consumers in order to simplify business processes, to provide actionable financial and clinical knowledge at the right time and place and to improve healthcare quality.”

Key Financial Highlights

Revenue for the second quarter was $322.6 million compared to $281.9 million a year ago, an increase of 14.4%. Income before taxes, non-cash and other items for the second quarter was $45.8 million or $0.13 per share compared to $30.0 million or $0.09 per share a year ago. Income before taxes, non-cash and other items for the second quarter includes approximately $3.6 million, or $0.01 per share, of charges primarily related to severance and recruiting expenses within the

WebMD Health segment, which was not previously included in our guidance or analysts’ consensus estimates for the quarter. Net income for the second quarter was $16.2 million or $0.05 per share compared to $5.8 million or $0.02 per share a year ago.

As of June 30, 2005, Emdeon had approximately $511 million in cash and short and long-term marketable debt securities.

Mr. Cameron continued, “I am pleased with our results for the second quarter and with the progress we are making across our businesses. While we still have much to do, it is gratifying to see that the planning and hard work to improve our operating infrastructure is beginning to yield benefits.”

Segment Operating Results

Emdeon Business Services revenue was $191.5 million for the second quarter compared to $166.0 million in the prior year, an increase of 15.3%. The increase in Emdeon Business Services revenue was attributable to the acquisition of ViPS as well as growth across our paid claims communications services and patient statement services. Income before taxes, non-cash and other items was $40.4 million compared to $28.9 million in the prior year. Operating margins increased as a result of decreases in HIPAA related expenses and lower transaction related expenses.

Emdeon Practice Services revenue was $78.6 million for the second quarter compared to $71.8 million in the prior year, an increase of 9.5%. Income before taxes, non-cash and other items was $8.2 million compared to $1.8 million in the prior year. Operating margins increased from 2.5% in the prior year to 10.4% as a result of revenue mix and improvements in our delivery and service infrastructure.

WebMD Health revenue was $40.5 million for the second quarter compared to $31.9 million in the prior year, an increase of 27.0%, driven by continued growth in our online public and private portals. Income before taxes, non-cash and other items was $4.4 million compared to $7.6 million in the prior year. These results include approximately $3.6 million of charges primarily related to severance and recruiting expenses. The Company indicated in April that these items were not included in its guidance.

Porex revenue was $20.4 million for the second quarter compared to $20.7 million in the prior year, a decrease of 1.6%. Income before taxes, non-cash and other items was $6.1 million compared to $6.3 million in the prior year.

Financial Guidance

The Company reaffirmed its full year 2005 financial guidance for revenue, income before taxes, non-cash and other items, and for net income. Per share amounts have been adjusted to reflect an increase in the number of shares outstanding resulting primarily from the conversion of $215 million of the Company’s 3 ¹/4% convertible notes. As previously announced following the Company’s first quarter, consolidated revenue for 2005 is expected to be between $1.260 billion and $1.30 billion, an increase of approximately 10% to 12% over 2004. Income before taxes, non-cash and other items is expected to be between $182 million and $202 million, or $0.51 to $0.57 per share. Net income in 2005 is expected to be between $73 million and $85 million, or $0.21 to $0.24 per share.

This guidance takes into account the $3.6 million of items at WebMD Health referenced above, the impact of the conversion and redemption of our 3 ¹/4% convertible notes and the actual expenses incurred in the first six months of 2005 related to the ongoing Department of Justice investigation.

Specifically for the third quarter of 2005, the Company expects revenues to be approximately $325 million to $335 million and income before taxes, non-cash and other items to be approximately $0.13 to $0.14 per share, and net income to be approximately $0.06 to $0.07 per share.

The Company’s guidance assumes weighted average shares outstanding of 356 million during the year.
