News Release — 24-Jun-2003

Pediatrix Notified of Billing Inquiry

FORT LAUDERDALE, Fla.—(BUSINESS WIRE)—June 24, 2003—Pediatrix Medical Group, Inc., (NYSE:PDX) today announced that it has been advised by a U.S. Attorney’s Office that it is conducting a civil investigation into Pediatrix’s Medicaid billing practices nationwide.

Pediatrix understands that the U.S. Attorney’s Office intends to make a document and information request, informally or by subpoena, within the next few weeks. Pediatrix intends to cooperate fully with this investigation.

Since 2000, Pediatrix, the nation’s largest provider of neonatal and maternal-fetal medicine physician services, has resolved similar Medicaid billing investigations with six state attorney general offices, including previously-announced settlements with Florida, Arizona, Nevada and Colorado. None of these settlements has had a material impact on Pediatrix’s financial condition and none involved an admission of wrong-doing on the Company’s part. The Company believes that its billing practices have been appropriate.

However, Pediatrix is not able to predict whether the investigation will have a material adverse effect on its business, financial condition or results of operations, nor is it able to estimate the amount of time such an investigation will take to be resolved.
