Likely not going to happen purely out of complexity if nothing else. Look at the list of ICD procedure codes[1] and imagine all of these with a price attached. Comprehensive, sure, but comprehensible? Ehhh.. pushing it.
"Hey, we'll do CPR, but that'll will be $100, please sign here so we can save your life".
The ala cart method seems like it might work until you start thinking about the logistics. If someone goes to a doctor complaining about chest pain, do we really want them to leave because an EKG and blood test are going to cost $200. No matter how much the doctor explains to them "You might be dying" plenty of people will walk out of the hospital once the bill is presented. In some of those situations, that's going to be deadly.
