-----------------------

(1) Calculated based on (i) 359,708,024 shares of Common Stock, par value
$0.0001 per share ("Common Stock"), of WebMD Corporation (f/k/a Healtheon/WebMD
Corporation, the "Issuer") outstanding on July 27, 2001, as reported on the
Issuer's Quarterly Report on Form 10-Q filed on August 14, 2001.



CUSIP No. 422209106                                                 Page 3 of 5


         This Amendment No. 3 amends and supplements the Schedule 13D filed by
Quintiles Transnational Corp. with the Securities and Exchange Commission on
June 5, 2000, as amended on June 30, 2000 and March 1, 2001, respectively, with
respect to the Issuer's Common Stock.

ITEM 4.  PURPOSE OF THE TRANSACTION

         Item 4 shall be amended to add the following information:

         Effective at the end of the day on October 8, 2001, Dr. Gillings
resigned from the Issuer's board of directors.

         On October 12, 2001, Quintiles and the Issuer entered into a settlement
agreement (the "Settlement Agreement"), which resolved all disputes between the
two companies that were the subject of litigation. A copy of the Settlement
Agreement is filed as Exhibit E to this Schedule 13D and is incorporated into
this Schedule 13D by reference.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         Item 5 shall be deleted in its entirety and replaced with the
following.

         Based on information contained in the most recent publicly available
filings of the Issuer with the Securities and Exchange Commission, Quintiles is
deemed to beneficially own the number of shares and the percentage of
outstanding shares of Common Stock listed on lines 11 and 13, respectively, of
Page 2 of this Schedule 13D/A. In addition, the number of shares of Common Stock
as to which Quintiles has sole or shared voting power and sole or shared
dispositive power, is listed on lines 7-10 of Page 2 of this Schedule 13D/A.

         On October 12, 2001, Quintiles ceased being a beneficial owner of more
than five percent (5%) of the Issuer's Common Stock.


ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER

         Item 6 shall be deleted in its entirety and replaced with the
following.

         On October 12, 2001, Quintiles and the Issuer announced the settlement
of the litigation between the companies and the resolution of their disputes.
Under the terms of the settlement, the companies agreed to terminate all of
their business agreements, including their Data Rights and Internet Product
Development and Marketing agreements, and the Issuer agreed to purchase from
Quintiles for $185 million in cash all 35 million shares of Issuer Common Stock
held by Quintiles.

         As part of the financial terms, Quintiles will also have the right to
receive a contingent payment (payable at Issuer's option in cash and/or stock)
in the event that, on or before June 30, 2004, Issuer is acquired at a price per
Issuer share greater than $4.00 or Envoy Corporation, a subsidiary of Issuer
("Envoy"), is sold at an aggregate price of greater than $500 million. Issuer
has no obligation to pursue either of these transactions under this arrangement
and has indicated that it has no intention of doing so.

         In the case of the execution of a definitive agreement related to an
acquisition of Issuer before June 30, 2003, the contingent payment to Quintiles
will equal the amount by which the




CUSIP No. 422209106                                                 Page 4 of 5

price paid exceeds $4.00 per share, multiplied by 35 million. If an acquisition
is agreed to after June 30, 2003, and closes before June 30, 2004, the
contingent payment will be 80% of that amount.

         In the case of the execution of a definitive agreement related to a
sale of Envoy before June 30, 2003, the contingent payment to Quintiles will
equal 10% of the amount by which the sale price exceeds $500 million. If a sale
is agreed to after June 30, 2003, and closes before June 30, 2004, the
contingent payment will be 80% of that amount.

         The foregoing is not a complete description of all the terms and
conditions of the Settlement Agreement and is qualified in its entirety by
reference to Exhibit E to this Schedule 13D which is incorporated into this
Schedule 13D by reference.

         Except as described in this Schedule 13D, as amended, there are no
contracts, understandings or relationships (legal or otherwise) among the
persons named in Item 2 and between such persons and any person with respect to
any securities of the Issuer, including but not limited to transfer or voting of
the securities, finder's fees, joint ventures, loan or option arrangements, puts
or calls, guarantors of profit, division of profit or loss or the giving or
withholding of proxies.
