Introduction:
Congenital anomalies are one of the leading causes of infant deaths and pediatric hospitalizations, but existing estimates of the associated healthcare costs are either cross-sectional survey studies or economic projections. This study sought to determine the percent of total healthcare expenditures attributable to major anomalies requiring surgery within the first year of life. 

Methods:
Utilizing comprehensive California state-wide data from 2008-12 and validated selection criteria, cohorts of major surgery, birth defect, and surgical anomalies were constructed alongside referent groups of non-surgical/non-defect newborns. Cost-to-charge and physician fee ratios were used to estimate hospital and professional costs, respectively. For each cohort, costs were broken down according to admission, birth episode, and first-year-of-life; with additional stratifications by birthweight, gestational age, and involved organ system.  

Results:
In total, 68,126 of 2,205,070 infants (3.1%) underwent major surgery (n=32,614) or had a diagnosis of a severe congenital anomaly (n=57,793), comprising $7.7 of $18.9 billion (40.7%) of total first-year of life hospitalization costs/expenditures, $7.1 billion (49.3%) of costs for infants with long birth hospitalizations (5+ days; n=211,791), $5.2 billion (57.8%) of total NICU admission costs. More specifically, infants with surgical anomalies (n=14,296) totaled $3.7 billion (19.6%) at $80,872 per infant. Cardiovascular and gastrointestinal diseases comprised most admission costs secondary to major surgery or congenital anomalies.   

Conclusion:
Considering the medical costs of all newborns, infants with congenital surgical anomalies consume a disproportionate cost within the US healthcare system. The care and associated costs of these infants, which are covered to a significant degree by Medicaid, represent a particular focus in an era of healthcare payment reform.
