Is it because the insurance coverage algorithms are too complicated? Because the different entities involved in a single treatment plan is too complicated to navigate? Because physicians feel that cost is orthogonal to medicine and they prefer not to be involved/prefer to recommend the ideal treatment based on a predicted outcome? All of the above?
It feels like if there were a particular hospital group / physician group that had this feature, they would attract a lot of attention. Just imagine, "Your initial differential diagnosis will not exceed $150 and we'll discuss treatment options or more conclusive diagnostic tests afterwards."
All I've heard so far are physicians who don't accept insurance but instead have a straightforward "menu" for common items, which is interesting but not what I think most people want.
