WEBMD CORPORATION COMPLETES ACQUISITION OF MEDIFAX-EDI

WebMD acquires a leading provider of real-time medical eligibility transactions

WebMD continues to expand its suite of reimbursement cycle management services
for nation’s healthcare payers and providers

ELMWOOD PARK, NJ (December 22, 2003) – WebMD Corporation (NASDAQ: HLTH) today announced that it has completed its previously announced acquisition of Medifax-EDI, Inc. for $280 million in cash, subject to customary post-closing adjustments. Medifax-EDI, a privately-held, Nashville-based company, is a leading provider of real-time medical eligibility transaction services and other claims management solutions to hospitals, medical centers, physician practices and other medical organizations throughout the U.S. Medifax-EDI will be combined with WebMD Envoy, the Company’s Nashville-based Transaction Services business.

As previously announced, just prior to closing, Medifax-EDI distributed its Pharmacy Services companies to its owner, an entity advised by Crescent Capital Investments, Inc. and these companies were not included in this transaction.

Medifax-EDI is a leading provider of medical eligibility transaction services which enable providers to verify insurance coverage for their patients on a real-time basis. WebMD Envoy provides electronic transactions and business process outsourcing services which enable the nation’s providers and payers to facilitate reimbursement. The acquisition of Medifax-EDI strengthens WebMD Envoy’s position as a provider of all-payer, all-transaction service offerings to the healthcare provider marketplace. When combined, WebMD Envoy becomes a leading supplier of both medical claims and real-time transaction solutions for both commercial and government payers.

Roger C. Holstein, CEO of WebMD, said, “The acquisition of Medifax immediately strengthens our service offering to payers and providers, enabling the provision of pre-adjudication real time transactions. The integration of Medifax with WebMD Envoy will be essential as we enhance our position as a leader for all-payer all-transaction services.”

David F. Bacon, Jr., President and CEO of Medifax-EDI, said, “On behalf of the entire Medifax team, we are very pleased to join the WebMD Envoy team. Combining our systems and technologies with WebMD Envoy’s strong distribution channels and large customer base presents exciting growth opportunities.”
