you're right about the hidden costs not mentioned in the article. He stayed at the hospital for 2 days, consulted with doctors, and received medication. this is why the bill is so high.
however, an x-ray should cost around $200. there's no need for an "expert" medical billing administrator here, $200 is double or triple the price of an x-ray in many european countries, and many facilities in america (where the youtuber lives) will charge less than $1000.
