Hospitals don't necessarily overcharge for everything, those prices are negotiated with insurance companies.

If you pay out of pocket a lot of times things are reasonably priced but obviously if you need significant hospital stay in the ICU or something you are going to be charged an insane amount of money, but even for just the nurse it cost the hospital 1000-1400 for 24 hours.

Whenever I've paid out of pocket for CT scan, MRI or my knee surgery-300, 500, 1700 respectively, those were all reasonable prices to me.
