Many of those “simple diagnostic procedures” are a tenth of the cost if done outside of insurance out of pocket. MRIs are one of them.

My routine blood work done via my doctor bills something like $1600 to my insurance every other year or so - but it do it on my own outside of the medical system for about $180 every six months.

No one should have to do this for necessary care - but once you get into things not typically covered by insurance like plastic surgery or LASIK the true costs are generally rather reasonable.

A whole shadow ecosystem for “health hackers” or whatever you might want to call it exists where standard medical stuff is 10% of the cost if paid out of pocket and through alternative prescribers. It’s a small subset of all available medical items, but the difference in true cost is illuminating.
