 Vaginal delivery with and without complicating diagnoses and caesarean section with and without comorbidities or major comorbidities account for four of the 15 types of hospital stays with low rates of ICU utilization (where less than 20% of visits were admitted to the ICU).During stays with ICU services, approximately 20% of costs were attributable to the ICU.A 2013 study found varying costs by facility for childbirth expenses in California, varying from $3,296 to $37,227 for a vaginal birth and from $8,312 to $70,908 for a caesarean birth.
