I have a personal story about dermatologists overcharging ridiculous amounts. I had a rash that I couldn’t explain on my back and chest. I took several visits to the dermatologist before it cleared. Now let me explain these visits. They were each less than 15 minutes long, the dermatologist did hands on work in on 2 of the 7 appointments. And the medicine he gave me, I later found out could have been bought at a pharmacy for $40. But this man, for less than 2 hours of work and half of a $40 tube of medicine, billed my insurance over $4,000 for the treatment.
