I have run into those types of scams. My favorite was the chiropractor who was part of an organization called Disc Centers of America. First red flag: didn't like the quality of my MRI that had not shown anything terrible. Then, he sent me to an imaging center(they owed him a favor) for a CT scan, I had to pay cash on the spot. Second red flag: we reviewed the CT scan. "look at that bulging disc! Man, there's more above. Good thing you got to me when you did". Third red flag: Twenty or thirty decompression treatments (not covered by insurance for thirteen thousand dollars. Fourth red flag: Wait! If you sign up today, the price will go down to nine thousand. And. we can set up the payments right here. i said. 'no thanks".
