ANS and Quality Systems, Inc. Partner to Integrate ANSLink Real Time Patient Eligibility with QSI's Practice Management Software
CHICAGO, IL -- October 2, 2000 -- Affiliated Network Services (ANS) and Quality Systems, Inc. (Nasdaq: QSII) announced today that they have signed an agreement to integrate ANS's ANSLinkSM Internet Eligibility component into QSI's practice management software and QUIC e-services suite.

By incorporating ANSLink's real time eligibility component, QSI will now deliver to its practice clients an end-to-end functionality, and succeed in removing the gap that many healthcare practices face -- incorporating up-to-the-minute patient eligibility data from health and dental plans. Through a seamless integration with its practice management software and EDI network, QSI's customers will have eligibility for patients with upcoming appointments confirmed, without the need to place calls or perform individual inquiries.

�We are excited about the partnership with QSI because it expands on our vision of a convenient, standardized and meaningful solution for carriers and providers,� said Dr. Fred Horowitz, president of ANS. �It's a win-win situation: QSI's provider clients are able to get the functionality they want through their EDI network and web site, and payors are happy because the additional convenience means fewer phone calls to check eligibility.�

�Our partnership with ANS allows us to immediately provide labor saving connectivity between carriers and our dental practice customers, who are under increasing pressure to streamline operations and optimize their performance,� said David Razin, Vice President, Business Development of Quality Systems. �The addition of the ANSLink technology to our e-services suite allows us to further fulfill Quality Systems' commitment to enable our customers to compete in the digital age.�

Affiliated Network Services is dedicated to accelerating healthcare transactions, enabling health and dental plans and providers to save money and time. Through the ANSLink web site, providers quickly access real time eligibility information, determine co-pay amounts and submit claims.

Quality Systems, Inc. is a developer and provider of computer-based practice management, medical records, and e-business applications for medical and dental group practices.
