(c) Exhibits 99.1 Press Release of Pediatrix Medical Group, Inc., dated September 28, 2004.

                                                                    Exhibit 99.1

          Pediatrix Lowers 2004 Quarterly EPS Guidance; Board Increases
                     Share Repurchase Program by $50 Million

           FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Sept. 28, 2004--Pediatrix
Medical Group, Inc. (NYSE:PDX) today revised its previously issued
earnings guidance for the three months ending September 30, 2004 and
the three months ending December 31, 2004. This revision is the result
of lower-than-anticipated revenues principally attributable to a
payor-mix shift from commercial to government payors that occurred
during the month of August 2004.
           Separately, the Board of Directors of Pediatrix authorized a
$50 million increase to its existing share repurchase program.
           For the 2004 third quarter, Pediatrix now expects earnings per
share of $1.04 to $1.06. Pediatrix also expects earnings per share of
$1.02 to $1.04 for the 2004 fourth quarter. The fourth quarter
guidance considers the seasonal impact of traditionally lower patient
volume, includes estimates for contributions from acquisitions
expected to be completed during the remainder of this year, and
assumes that the payor mix remains at current levels. Pediatrix's
previous guidance was for earnings per share of $1.11 to $1.13 for
each of the 2004 third and fourth quarters.
           For all of 2004, Pediatrix expects earnings per share to be in a
range of $3.90 to $3.94, up by 14 to 15 percent from 2003.
           Pediatrix expects that same-unit revenue for the 2004 third
quarter will be slightly negative when compared against the 2003 third
quarter due to the shift in payor mix. However, Pediatrix expects
same-unit patient volume growth at neonatal intensive care units
(NICUs) staffed by its physicians to be within its historical range of
3 to 5 percent for the 2004 third quarter when compared with the same
period of 2003.
           Cash flow from operations is expected to exceed $120 million for
all of 2004.
           Including today's announcement to increase the existing share
repurchase program Pediatrix's Board of Directors has authorized the
repurchase of up to $100 million of its common stock since early
August 2004. Pediatrix has completed $7 million of that repurchase to
date, leaving the Company with the authorization to acquire up to an
additional $93 million of its common stock. The share repurchase
program allows the Company to make open market purchases from time to
time based on general economic and market conditions. Pediatrix has
not included any possible impact of this share repurchase program in
its current earnings guidance.
           Pediatrix expects to report complete financial results for the
three months ending September 30, 2004, on November 4, 2004. These
final results are subject to completion of the quarter and customary
financial closing and review procedures.
