                           ATTACHMENT A TO FORM 12b-25


                 Form 10-Q for the Quarter Ended March 31, 2007



PART III - NARRATIVE

         Although the management of Pediatrix Medical Group, Inc. (the
"Registrant") has been working diligently to complete all required information
for its Form 10-Q for the quarter ended March 31, 2007 (the "Form 10-Q"), the
Registrant is unable to file its Form 10-Q within the prescribed time period
without unreasonable effort or expense. The reason causing the Registrant's
inability to file timely could not be eliminated by the Registrant without
unreasonable effort or expense.

         As disclosed in the Registrant's Form 8-K filed with the Securities and
Exchange Commission on March 1, 2007 (the "Form 8-K"), although the Audit
Committee of its Board of Directors (the "Audit Committee") has not completed
its work or reached final conclusions with respect to its previously disclosed
independent review of the Registrant's practices relating to its stock option
grants, management has concluded, and the Audit Committee has approved the
conclusion, that the Registrant's financial statements for the fiscal years
ended December 31, 1995 through and including 2005, the interim periods
contained therein, and the fiscal quarter ended March 31, 2006 and all earnings
and press releases and similar communications issued by the Registrant relating
to periods commencing on January 1, 1995 and ending on March 31, 2006 should no
longer be relied upon and that its financial statements will need to be
restated. The restatement is expected to include additional non-cash
compensation expense and the resulting tax and accounting impact. The Registrant
has not completed its determination of the amount of such charges or which
periods may require restatement. Consequently, although the Registrant issued a
press release on May 10, 2007 (the "Press Release"), announcing revenues and
other selected unaudited financial information for the quarter ended March 31,
2007, the Registrant is unable to file the Form 10-Q by the required filing date
of May 10, 2007. Based on the status of the review to date, the Registrant
currently anticipates that it will not be able to file the Form 10-Q on or
before the fifth calendar day following the prescribed due date according to
Rule 12b-25 under the Securities Exchange Act of 1934.

                           ATTACHMENT B TO FORM 12b-25

         As reported in the Press Release, the Registrant expects to report the
following significant changes in its results of operations in the Form 10-Q: an
increase in net patient service revenue of 14 percent from $187.7 million to
$214.5 million for the three months ended March 31, 2007 compared to the same
period in 2006. Because the Audit Committee has not yet completed its review of
the Registrant's practices relating to its stock option grants and reached final
conclusions with respect thereto, at the date hereof, the Registrant is unable
to determine if any other significant change in its results of operations from
the corresponding period for the last fiscal year will be reflected in the
earnings statements to be included in the Form 10-Q.
