Even better: clearly the market has proven that it's possible to offer these services with transparent pricing. Why can't hospitals keep pace?
This also raises the question why preventative care often falls into the same category. Lawyers have a predictable billable rate, personal physicians and doctors often don't. Most scheduled hospital procedures require multiple consultations and planning before the procedures take place. Most of that stuff is not transparently priced.
There's no reason why a hospital shouldn't be able to figure out the cost of minor anesthesia before a scheduled minor surgery. That's not a surprising part of the procedure, that should be something that's fully negotiated with insurance and disclosed to the patient beforehand so they can decide.
> Has the demonstrated value been worth the cost?
Yes, absolutely, you can find tons of stories online about people negotiating smaller bills because itemized bills turn out to include services that they never requested (and in some cases services that were never even actually performed). If you talk to experts about managing personal health costs, pretty much all of them will tell you to always request an itemized bill after you visit a hospital or doctors office.
It's also absolutely worthwhile because you're seeing creative line items like $500 for aspirin that prove that the costs of the services aren't being based on market rates. That's really important information because it opens the door to other questions like "why are these prices what they are", and "can you tell me in advance before you give me a $500 aspirin?"
I mean... you're saying this is the norm in complex industries, it absolutely is not. Complex industries are complex because they don't know up front what they'll be billing you for. That's not even remotely the same thing as "we think your stay should cost $5000 for reasons we can't disclose, so I guess we'll jack up the aspirin cost after the fact to try and prevent anyone from questioning us."
It is extremely worthwhile to put hospitals in a position where they have to answer consumers why an in-patient aspirin is priced so much higher than the market rate for the drug. I don't know if this is your intention, but what you're implying when you say that the itemized bills aren't accurate is that hospital pricing isn't based on any kind of competitive or visible market rate, or even anything objective at all. Which is a pretty bold claim.
Other industries with high-variability pricing exist, but they're not just making up numbers completely out of thin air after the fact and then lying about line items to try and justify that cost. Hopefully hospitals aren't doing that either. But if they're not, if they are actually basing their prices off of the combined prices of the services they provided... then we gotta ask about that $500 aspirin, because that's a weird price.
