Shrouded prices for blood tests in the U.S.

One of the features of the American health care system is that prices are heavily shrouded--insurance companies reach negotiated prices with providers, that may be very different with different providers, and very different from list prices, and are not quoted. So prices aren't nearly as informative in health care as in most other markets.

Here's a NYT story that focuses on blood tests:

They Want It to Be Secret: How a Common Blood Test Can Cost $11 or Almost $1,000
Huge price discrepancies like that are unimaginable in other industries. Also unusual: not knowing the fee ahead of time.
