A New York Times article recently found that a cost of ONE stitch can cost up to $500.
You can fine the whole article here.
From the NYT article, a hospital called California Pacific has the following inflated prices (market prices in parenthesis):
Tylenol with codeine pill
IV fluid bag
$137 (Under $1)
$1,791 – Hospital fee only ($358 -Includes doctor)
Without insurance, these bills can really add up. Let us know any crazy markups you have experienced in hospitals (or anywhere) in the comments below.
