Item 5.  Other Events

         On March 14, 2000, Medical Manager Corporation (the "Company") was
served with a summons in a lawsuit filed on February 17, 2000, against the
Company, its subsidiary, CareInsite, Inc. ("CareInsite"), and certain of their
officers and directors, among other parties, in the New Jersey Superior Court,
Chancery Division, in Bergen County. The plaintiff purports to be a holder of
CareInsite common stock. The lawsuit, captioned Ina Levy, et al. vs. Martin
J.Wygod, et al., C-59-00, purports to bring an action on behalf of the plaintiff
and others similarly situated to enjoin the defendants from consummating the
proposed merger of Medical Manager and CareInsite with Healtheon/WebMD Corp.
(the "Merger"). The plaintiff alleges that the defendants have breached their
fiduciary duties in that the proposed Merger favors the interests of the Company
and its shareholders over the interests of CareInsite's minority shareholders.
The plaintiff also alleges that the proposed Merger provides the defendants and
other Medical Manager shareholders with a premium which exceeds the premium
provided to CareInsite's minority shareholders. The lawsuit seeks, among other
things, an injunction prohibiting the proposed Merger unless certain mechanisms
are implemented by CareInsite, as well as plaintiff's costs and disbursements.
The Company believes that this lawsuit is without merit and intends to
vigorously defend against it. No assurances can be given that this lawsuit will
not have a material adverse effect on the Company's business, financial
condition or results of operations.
