A paradox of medical costs is that people who can least afford them — the uninsured — end up being charged the most. Insurance companies, with large numbers of customers, have the financial muscle to negotiate low rates from health-care providers; individuals do not. Whereas insured patients would have been charged about $900 by the hospital that performed Pat's biopsy (and pay only a small fraction of that out of their own pocket), Pat's bill was $7,756. For lab work — and there was a lot of it — he was being charged as much as six times the price an insurance company would pay.
There are lots of things to hate about our current medical system, and all of us have our own favorite things to hate. This is mine: the fact that the system massively overcharges you if you're uninsured, and they do it just because they can. If you're uninsured, you've got no leverage, no alternatives, no nothing. So you get screwed. It's like the shopkeepers who charge twenty bucks for a pair of flashlight batteries after hurricanes. Maybe it's the free market at work, but if so, that's all the worse for the free market. In the healthcare biz, it just doesn't work.
