The cost of having a baby ranges from $3,000 to $37,000 in the state of California, a new study published in the journal BMJ Open has found, with no apparent logical explanation for the wild range or the high costs. The study highlights some of the issues with soaring health care costs in the U.S. More from NBC News:
"Even after adjusting for patient characteristics like their length of stay and their age and even adjusting for hospital characteristics and things like the cost of living, we found significant variations in price," said Dr. Renee Hsia of the University of California, San Francisco, who led the study.
For a simple, uncomplicated vaginal delivery, prices ranged from $3,296 to $37,227, Hsia's team found. For a C-section, women were billed between $8,312 and nearly $71,000.
"This is, unfortunately, the appalling state of affairs of health care in the United States," Hsia said.
Even getting the prices wasn't easy. Hsia's team had to tease it out from state data on each patient admission. They figured out which ones were for childbirth, and then eliminated any complicated cases.
"Of course we would expect that if woman is in the hospital for six days as opposed to for two days, she would have larger charges," Hsia said. "And if you deliver a baby in San Francisco, it will be more expensive than if you deliver in a cheaper suburban area."
But the prices her team found — they are not naming individual hospitals — varied way more than these differences should account for.
The main problem is that patients do not know how much their insurers are paying on their behalf, and they certainly don't know the price up front, Hsia says.
"This study shows that the market doesn't take care of health care the way that we would like," Hsia said in a telephone interview.
"If I go to buy a dozen eggs at the grocery store, I know if they are cage-free," she added. "As a consumer, I know what I am buying and why there might be price differences. But as a patient, I don't even know what things cost."
Health experts say this is one of the main reason U.S. health care is so much more expensive than in other countries — $8,915 per person in 2012, for a total of $2.8 trillion. Of that, $882 billion is spent on hospitals services, like giving birth.
In May, the federal government said it would start publishing data on hospital charges. Their first numbers confirmed what health reform advocates complained about for years: The charges vary enormously, and for seemingly unclear reasons.
The Obama administration hopes that publishing prices will help force health care providers to be more consistent in their billing.
