According to a HuffingtonPost.com article, "When a patient arrives at Bayonne Hospital Center in New Jersey requiring treatment for the respiratory ailment known as COPD, or chronic obstructive pulmonary disease, she faces an official price tag of $99,690.
"Less than 30 miles away in the Bronx, N.Y., the Lincoln Medical and Mental Health Center charges only $7,044 for the same treatment, according to a massive federal database of national health care costs made public on Wednesday." (read more)
The problem with healthcare is that it isn't a marketplace in the usual capitalist sense of the term, where market forces work to keep prices low. Keeping prices low in health care is pretty much on the honor system.
When one needs health care, one typically doesn't shop around, especially when the need is urgent. One goes either to the nearest ER or where your doctor tells you to go. If you want to go somewhere else, there's a good chance s/he won't be one of the doctors who can practice there.
By contrast, when shopping for a car you can visit several different dealerships, get quotes, weigh whatever differences there are beyond price such as their reputation or extras they might throw in, and make a halfway intelligent choice, typically largely driven by how much you'll pay
This is the sort of capitalistic environment that functions to keep prices low in a normal marketplace. Health care functions in a very different way such that price competition hardly exists at all. Institutions that do try to keep costs down do so at their own peril, and may only be doing so due to the mandate under which they were created. For example, they may be run by a charity of some sort (yes, sometimes a religious charity) intent upon serving the community by keeping medical costs down.
What can be done?
