Even Deeper Utilization of NaviNet Multi-Sponsor Communications Portal Accompanies Dramatic Growth of NaviMedix Provider Network

CAMBRIDGE, Mass. — May 21, 2008 — NaviMedix, the leading innovator in automating healthcare provider communications, today announced that its online communications platform, NaviNet®, is now used by over half a million providers across the country to interact with leading national and regional health plans, and other sponsoring healthcare service organizations. In addition to the dramatic increase in the number of providers in its network, NaviMedix has also seen even deeper utilization of NaviNet as users take advantage of more sophisticated clinical and financial communications and interact with newer sponsors. NaviMedix continues to enroll more than 1,000 new physicians and clinicians in its network every day.

NaviMedix enables health plans and other NaviNet sponsors to offer a wide range of clinical, financial and administrative transactions to physician offices and hospitals in all 50 states – the largest provider communications network of its kind. NaviMedix solutions deliver unprecedented transaction volume and value to its health plan customers and partners by providing access to a ready-made network of over 500,000 providers already using NaviNet to interact with multiple healthcare organizations. Providers have found that NaviNet has become an indispensable part of their office’s daily processes. Among other benefits, NaviNet offers real-time access to health plan information, HIPAA-compliant and secure exchange of patient data, and the convenience and efficiency of communicating with multiple organizations from one site.

“In the last couple of years NaviMedix has not only added most of the major national payers to our NaviNet offerings, but we have also added extremely useful functionality like PHRs, care gap alerts and real-time determination of patient payment responsibility,” said Tim Hargarten, president and CEO of NaviMedix. “That kind of breadth and depth is a very powerful combination for practices and it has driven our new-user enrollment rates off the charts. Our interactive communications network that reaches more than half a million providers is something the industry has never seen before and we are just beginning to scratch the surface of its potential to improve care and reduce costs across the healthcare system.”
