It probably wasn't hyperbole. I had to learn the lesson the hard way because of the FAA as well. FAA required a follow-up CT after kidney stone. Got hit with a $3,000 bill for it from a large healthcare provider (it was "covered", but it hit my high-deductible plan). Next time I needed a CT for the FAA, I went to the clinic literally across the street and it was about $350. All this to document what the urologist said all along were a few small retained stones positioned in an way that they weren't ever coming out. My urologist humored the FAA, but said all along none of the follow-up testing was medically necessary. I've been on BasicMed since day 1 that it was available as an option.
