I briefly worked in healthcare at a tech startup. The thing you quickly learn is that the market for healthcare is fundamentally broken. You could invent something that saves a patient $10,000 and they will never know. The hospital and doctors won't care about saving money. And the insurance company has no leverage to make them. And it will never make it onto the patient bill in a way that they understand.
And as much as doctors and hospitals love to paint insurance as the bad guy, the only reason things like prior authorization is a pain in the ass is because doctors don't actually put in any effort into prescribing generics or really learn how much anything costs. This is highly unusual in most professions: Imagine if your roofer grabbed whatever shingles they liked best and billed you for it after they were up. Now imagine every roofer worked the same way.
