It all began when Dr. Renee Hsia of the University of California at San Francisco received a simple request from a good friend who had checked into a local hospital for an emergency appendectomy. The fairly routine procedure took place 19,368 times during 2009 in California.
After he returned home, he received a bill from the hospital for $19,000, his co-payment for the parts of the $54,000 operation that his insurance company didn’t cover. “He wanted to know if this was the usual and customary charge for a one-day stay in the hospital,” she recalled.
And thus began her research into pricing variability in the state, which was published this week in the Archives of Internal Medicine. The prices ranged from $1,529 to $182,955 with the median hospital charge of $33,611, the study showed.
The prices not only varied between hospitals, they varied within hospitals. The largest spread occurred at one hospital, which Hsia wouldn’t reveal, where the cheapest appendectomy went for $7,504 while the most expensive charged was $171,696. There were numerous hospitals where the spread was $100,000 or more.
“They had the same diagnosis, but different things could have been done,” she said. For instance, one patient could have had multiple imaging tests and robotic laparoscopy, while the other received no imaging and a regular laparoscopy. There’s no evidence to suggest one set of alternatives had better outcomes than the other.
