Pediatrix Medical Group, the neonatal and pediatric physician-staffing company formerly known as Mednax, has been the defendant in lawsuits spanning federal fraud allegations, insurer overbilling claims, securities cases, a large data breach class action, and thousands of consumer complaints about surprise medical bills. The most consequential resolutions include a $25 million False Claims Act settlement with the Department of Justice in 2006 and a $6 million data breach settlement approved in 2024. Others, including a $50 million overbilling suit brought by Aetna, ended in confidential terms.
The $25 Million Federal Fraud Settlement
In September 2006, Pediatrix paid $25,078,918 to resolve U.S. Department of Justice allegations that it had systematically upcoded bills submitted to Medicaid, TRICARE, and the Federal Employees Health Benefits Program between January 1996 and December 1999. The government said Pediatrix used billing codes for critically ill infants when the babies were not, in fact, critically ill.
The alleged pattern was substantial. On admission days, the DOJ said, one-third or more of the infants billed at critical-care rates did not meet the threshold for critical illness. That figure rose to 50 percent or more on subsequent care days and 85 percent or more on discharge days.
The case began as a qui tam action filed by Dr. Daniel M. Hall, a Colorado neonatologist, who received $1,557,588 as his whistleblower share. U.S. Attorneys in Maryland and Colorado led the investigation with Medicaid Fraud Control Units in North Carolina, South Carolina, New Jersey, and Maryland. As part of the resolution, Pediatrix entered a five-year Corporate Integrity Agreement with the HHS Office of Inspector General. The company denied wrongdoing and said it had cooperated fully.
Aetna’s $50 Million Overbilling Lawsuit
In November 2017, Aetna sued Mednax and its subsidiary Pediatrix Medical Group of Florida over an alleged upcoding scheme running from 2009 through at least September 2016. Aetna put the overbilling at roughly $50 million and said the company exaggerated newborn conditions to justify unnecessary tests and higher billing rates. One specific claim: that Pediatrix billed advanced auditory brainstem hearing screens at three times the rate of non-Mednax clinicians.
In October 2018, U.S. District Judge Wendy Beetlestone of the Eastern District of Pennsylvania denied Mednax’s motion to dismiss, ruling that questions about the statute of limitations and Aetna’s reliance on Mednax’s billing forms could not be resolved at the pleading stage. A parallel case in the Southern District of Florida was voluntarily dismissed the same year.
In early 2021, Aetna filed a 30-page sanctions motion accusing Mednax of deleting “years’ worth of emails related to the lawsuit.” A Mednax spokesperson denied any spoliation, saying the company had “not destroyed or otherwise spoliated evidence in this case, which is itself without basis.” In July 2021, Aetna voluntarily dismissed the suit with prejudice. Each side bore its own legal costs, and the terms were confidential.
Data Breach Class Action Settlement
A June 2020 phishing attack on Mednax exposed the personal information of approximately 2.7 million patients and triggered a multidistrict class action consolidated in the Southern District of Florida before Judge Rodolfo A. Ruiz II as In Re: Mednax Services, Inc., Customer Data Security Breach Litigation.
On October 4, 2024, Judge Ruiz granted final approval to a $6 million settlement, calling it “fair, reasonable and adequate.” Class members could claim up to $5,000 for documented out-of-pocket expenses, up to $420 for time spent responding to the breach, and three years of medical-fraud monitoring. Attorneys received $1.8 million in fees, or 30 percent of the fund.
SEC Stock Option Backdating Case
In March 2009, the Securities and Exchange Commission filed a civil complaint against the company (then operating as Mednax) alleging that it backdated stock option grants to executives and employees between 1997 and 2000. By selecting favorable exercise prices in hindsight, the company failed to recognize $8.8 million in compensation expenses, overstating pretax income by roughly 6.74 percent for the period.
An internal audit committee found that a former senior financial officer, who resigned in May 2000, was responsible for most of the backdating and personally realized about $12,000 from grants to himself. CEO Roger Medel did not receive backdated grants but was found to have been “actively involved in determining grant recipients and amounts” and party to emails about favorable grant dates. Medel’s spouse, a founding physician, received backdated grants and offered to repay $519,000. President and COO Joseph Calabro offered roughly $145,000, and CFO Karl Wagner about $155,000; neither was found to have engaged in intentional misconduct, though both were faulted for inadequate oversight.
The company settled without admitting or denying the allegations and consented to an injunction against future securities-law violations. The SEC credited its cooperation.
Shareholder Securities Class Actions
Pediatrix and Mednax have faced three notable securities class actions:
- A 2001 case in the Southern District of Florida settled in December 2001 for $12 million in cash, with no admission of liability. Pediatrix absorbed about $750,000 in legal costs; insurance covered the rest.
- A 2003 wave of shareholder suits followed the disclosure of a U.S. Attorney’s Office investigation into the company’s Medicaid billing practices, which drove a 24 percent stock drop. All the suits filed in June and July 2003 were voluntarily dismissed without prejudice by October.
- Cambridge Retirement System v. Mednax, Inc., filed in 2018, alleged that executives made misleading statements about the viability of the company’s anesthesiology-acquisition strategy, inflating the stock price from February 2016 through July 2017. The stock fell more than 15 percent after the company disclosed it had failed to complete any anesthesiology acquisitions.
Surprise Billing Complaints
Outside formal litigation, Pediatrix has drawn sustained complaints from families over surprise medical bills. The mechanic is straightforward: Pediatrix clinicians often work inside hospitals as out-of-network providers, so a parent who confirmed that the hospital and obstetrician were in-network may still receive a separate, out-of-network bill from Pediatrix for newborn hearing screens, NICU attendance, or delivery standby.
Pediatrix administers hearing tests to nearly one million newborns annually. Between January 2019 and mid-November 2021, 192 complaints were filed against Pediatrix and Mednax with the Better Business Bureau, most about billing and collections. An earlier BBB tally cited more than 70 similar complaints as of mid-2018.
Reported individual cases include an obstetrician, Dr. Michelle Barhaghi, who received a $6,538 charge for her own unplanned cesarean plus a separate $1,311 bill for her baby’s discharge preparation, which was withdrawn after a media inquiry. Sarah Tela spent more than a year, with BBB assistance, resolving a $1,010 bill for a nurse practitioner’s attendance at a birth after her insurer rejected the claim over an incorrect date of service. Christine Malik was billed $326 for a newborn hearing screen that produced a false positive; her insurer paid $177. Sarah Hayes received a surprise bill exceeding $1,000 after her son’s birth despite having confirmed in-network status for her hospital and doctors; Pediatrix ultimately waived the charge.
The federal No Surprises Act, signed in 2020 and effective in 2022, was designed to shield insured patients from balance bills in situations like these. Pediatrix publicly supported provisions requiring arbitrators to consider factors beyond insurers’ internal benchmark rates, and has identified the law’s evolving regulations as a risk factor in its SEC filings.
