I have spent a week in a hospital twice, once in the late 90s, once in the lates 00s. Different hospitals, different health plans.
Here's the thing: in the 90s experience, I received a complete itemized bill, organized by time and day, for everything that was done to me. I didn't have to pay, my insurance did, but I received copies of the bill. In the 00s, I received virtually nothing. Again, my insurance paid, and I was just given the very briefest of letters explaining that I was covered, and how to handle short term disability, and the like.
I found receiving the complete itemized bill truly enlightening. What I learned was:
+ exactly what was done to me in the hospital and when
(I was not in a position to understand when I was admitted)
+ exactly what was being charged
+ exactly how expensive everything was
+ some charges did seem erroneous, perhaps for treatments that did not take place
The sum of the bill was staggering. But it was truly a good thing to see the bill. It helped me understand exactly what had happened. It served as a reference for googling my illness and treatment. It helped me understand the costs.
It helped me appreciate the efforts by others to get me that coverage. And it let me return some of that by giving me a way to check for mistakes in the billing.
I hope everyone has the coverage they need when they need it.
I do think that part of every medical service should be a completely itemized bill. I think it's a useful reference for the patient, I think it's a simple way to inform everyone on the complexities and costs of healthcare, and it's a simple way to encourage informed use, and correct mistakes.
If everyone had these bills, there would be websites developed to explain, compare, manage them, and it would help eliminate many of the games that hospitals seem forced to play.
So it would also encourage better accounting and put better incentives in place to have that better accounting.
