News Release Details

SANTA CLARA, Calif., BURLINGTON, North Carolina, October 4, 1999 -- Healtheon Corporation (NASDAQ: HLTH) and Laboratory Corporation of America® Holdings (LabCorp®) (NYSE: LH), one of the largest national clinical laboratories in the United States, today announced that LabCorp has selected BenefitCentral™, Healtheon's online enrollment and benefits management service, to streamline the process of benefits management for approximately 18,400 LabCorp employees. BenefitCentral will be deployed and serviced by Buck Consultants, a leading worldwide human resources consulting firm.


As previously announced, Healtheon and WebMD agreed in May to merge to form Healtheon/WebMD, the first end-to-end provider of healthcare information and services. Additionally, LabCorp and Healtheon recently entered into an e-commerce agreement for Healtheon to process laboratory requests and reports for physicians using LabCorp's clinical laboratory services.


Healtheon's BenefitCentral is an Internet-based service used by employers, employees and members, consultants and payers to provide online enrollment and benefits management. BenefitCentral enables employers to better manage benefit enrollment and administration and to improve the accuracy of critical data. Plan administrators benefit from an enormous improvement in their productivity while using the Internet. BenefitCentral also allows human resource administrators to tailor their benefits programs to their company's needs.


Employees can access BenefitCentral from home, work or on the road to compare health plans, search provider directories and electronically enroll in or change their benefits online. This reduces the costs and errors associated with today's paper-based enrollment systems. BenefitCentral also provides secure e-mail between the employee and employer to simplify customer service communications.


“We are pleased that LabCorp has selected BenefitCentral as its benefits administration service,” said Sanjiv Luthra, general manager for Employer Services, of Healtheon. "It is another example of how Healtheon is enabling companies like LabCorp to address Internet-enabled connectivity among healthcare participants - in this case, connectivity between employees, their health plans and their physicians."


“BenefitCentral will provide our employees with a fast, accurate and secure method of managing their benefits and obtaining information. It also will help us collect accurate and timely data, helping us better manage our benefit plans,” said Bradford T. Smith, Executive Vice President, Human Resources, of LabCorp.


“The partnership we have developed with Healtheon to deploy and service BenefitCentral allows us to provide our clients with a benefit management system that is secure and cost-effective,” said Steven J. Ferruggia, Principal and National Director of Buck Consultants' Health and Welfare Consulting Services. “Through the use of the Internet, BenefitCentral connects all participants, allowing employees to enroll in benefit plans in real time.”
