HCCI data on the cost of childbirth was mentioned in a report by NPR.
From the article:
"C-sections also cost more than vaginal deliveries. In the Denver area, for instance, the average vaginal delivery costs $7,716 while the average C-section costs $14,274, according to 2019 data from the Health Care Cost Institute. On average, commercial and Medicaid insurers pay 50% more for C-sections than for vaginal deliveries, according to a 2013 report by Truven Health Analytics, a health industry consulting group."
