MEDNAX, Inc. (NYSE:MD) specializes in intensive care for critically ill newborns and pregnant women. In January 2009, Pediatrix Medical Group changed its name to MEDNAX, Inc. 
As of 2007, PDX had more than 1000 affiliated physicians in its network, all of whom focus on neonatal care, neonatal cardiology, and maternal-fetal care.  PDX has expanded in the last 2 years into the field of anesthesiology and says it will continue its strategy of acquiring related physician practices to enlarge its network.
PDX earns revenue from its physicians' patients. 26% of revenues come from reimbursement through government programs such as Medicare and Medicaid, 63% come from commercial insurance HMOs and PPOs, and around 10% from other third-party payors.
Pediatrix provides specialized intensive medical care for newborn babies, critically ill children, and expectant mothers through a network of affiliated hospitals and physician practices. As of December 2007, PDX's pediatric care network consisted of more than 1000 affiliated physicians based in the continental US and Puerto Rico. Most physician practices affiliated with PDX are based in hospitals in neonatal intensive care units (NICU) as well as clinics providing care for pregnancies, pediatric cardiology, and other pediatric specialties. 
In an effort to build upon its core competency as a specialty health care provider, PDX has expanded its neonatal and maternal-fetal care services to include anesthesia care. Pediatrix's affiliated anesthesiologists work with surgeons in hospitals, ambulatory emergency centers, and office practices by providing pain control and patient medical care throughout surgery. The firm plans to expand this division of its services in future years to diversify its specialty care services portfolio. 
The following chart shows a breakdown of Pediatrix's network.
|Physician Specialty Area||Number of PDX Physicians|
|Neonatal Clinical Care (NICU)||788|
|Pediatric Cardiology Care||69|
|Pediatric Intensive Care||37|
|Hospital-based Pediatric Care||16|
|Advanced Practice Nurses||1315|

|Total Number of Physicians||1072||17.29%||914||9.59%||834|
|Number of Births||707,274||4.88%||674,336||7.046%||629,948|

PDX's revenues come from compensation of the professional services provided by the company's affiliated physicians and nurses. Compensation for health care services from PDX physicians are given by third-party payors rather than the patients themselves. These third-party payors include government-funded health care plans such as Medicaid and Medicare, managed care organizations, and other commercial health insurance plans including HMOs and PPOs . A breakdown of revenues received from each type of third-party payor is shown in the table below.
Compensation rates for the services provided by PDX physicians are not negotiated for government-sponsored plans and state-sponsored managed care organizations. Anesthesia care services are paid by the Medicare plan, while neonatal and maternal-fetal care services are paid by the Medicaid plan.
Throughout its company history, PDX has expanded its specialty care services to newborns and expectant mothers by acquiring private physician practices. In 2008, PDX has acquired three major practices specializing in neonatal and maternal-fetal care, including:
All three acquisitions were fully paid in cash, and all are expected to contribute to Pediatrix's earnings immediately. As a result of acquisitions, PDX's revenues increased by $42.2 million, $45.8 million, and $41.1 million respectively in fiscal years 2007, 2006, and 2005. 
In March 2008, Pediatrix completed the sale of its newborn metabolic screening division to PerkinElmer for a cash sum of $66 million. This newborn metabolic screening lab analyzes more than 50 genetic disorders in newborns through its StepOne newborn screening product, and generated revenues of around $15 million in 2007.  Pediatrix continues to operate a separate internal newborn hearing screening service based in hospitals. The two companies will also cooperate in future research to identify possible new mass spectrometry technologies in prenatal and neonatal testing. 
From 1994 to 2007, the number of preterm births (babies born after less than 37 weeks of gestation) grew by a compound rate of 1.7%, from 434,804 to 525,000 births. In 2007, preterm births represented 12.7% of all births in the U.S. The March of Dimes predicts that preterm births will continue to increase in the next year, to 543,000 births, or around 12.8% of all births next year. Similarly, the number of low-weight births has been increasing at the compound rate of 1.45% from 1994 to 2007, consisting of approximately 8.1% of all births in the U.S. 
Births at facilities where PDX affiliated physicians practice consist around 16% of all births in the U.S., and PDX physicians treat around 11% of all babies born at these facilities. The rise in premature births and low-weight babies will increase the number of NICU admissions, which increases potential patients for PDX affiliated physicians. 
In 2007, 89% of PDX revenues came from reimbursement from managed care programs and government healthcare reimbursement programs such as Medicare and Medicaid (see chart above, in Business Financials section). Therefore, reductions in coverage and reimbursement practices from third-party payors including Medicaid, Medicare, and commercial managed care programs will adversely affect PDX's revenue. According to estimates by PDX, there has been a general decline in insurance coverage and reimbursement practices for most private employers; reduced insurance coverage by governmental and commercial programs would shift PDX's third-party payor mix and result in potential decrease in net patient service revenue. 
PDX's business strategy is completely based on successful expansion of its physician base through acquisition of private physician practices in neonatal health services. As a result, it is completely dependent on the successful and efficient integration of the newly-acquired practices into its corporate structure to expand patient base. PDX plans to continue this business strategy in the anesthesiology sector. Due to differences in the nature of regulation and compensation for anesthesiology services from neonatal health services, PDX may meet potential obstacles in successfully implementing its acquisition-based business strategy to expand its market base in the anesthesiology sector. One important difference is that anesthesiologists typically do not operate their own private practices but circulate in various medical practices where their services are needed. This would prohibit PDX to extend its acquisition-based business strategy to the anesthesiology sector. 
Since PDX is focused on specialized segments of medical care, its pure play competitors are not publicly traded companies. We therefore compare PDX to other specialized healthcare service providers who operate and make money through similar business models. The comparison is useful not only because the business models are similar, but also because these specialized healthcare providers could also expand to the neonatal and anesthesiological areas that PDX focuses on, much like PDX has expanded from purely neonatal and maternal-fetal services to include general anesthesiology as well.
