WEBMD CORPORATION TO BE RENAMED EMDEON CORPORATION

ELMWOOD PARK, NJ (August 4, 2005) — WebMD Corporation (NASDAQ: HLTH) today announced that it is now operating under the name Emdeon Corporation. The Company’s ticker symbol will remain HLTH.

Kevin Cameron, Chief Executive Officer of Emdeon Corporation, stated: “While our name is changing, our mission and goals remain the same. As a leading provider of business, technology and information solutions, we intend to continue to work on behalf of our payer, vendor and provider customers to transform 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.”

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.

Emdeon Corporation’s businesses include:

• Emdeon Business Services, which provides revenue cycle management and clinical communications solutions that enable payers, providers and patients to improve healthcare business processes. Emdeon Business Services offers a full suite of products and services to automate key healthcare business functions, including electronic transaction services, document management solutions, payment services, print-and-mail services, decision support and data warehousing solutions, and consulting services.

• Emdeon Practice Services, which provides physician practice management and electronic health record software and related services. Its innovative solutions are used by large and small medical practices in all specialties to improve efficiency and enhance patient care.

• WebMD Health, which provides health information services for consumers, physicians, healthcare professionals, employers and health plans through its public and private online portals and health-focused publications. WebMD’s mission is to be the most trusted brand of health information, providing the most effective and efficient channel to reach, inform and educate consumers and providers.

• Porex, which manufactures and distributes porous plastic products and components used in healthcare, industrial and consumer applications.

At the Annual Meeting of Stockholders of the Company 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. The implementation of operational and branding use of the name Emdeon will begin immediately.
