$400 a month, in a reasonably busy dermatologists office, would probably come to about $20 "per use". A lot less if you have multiple patients use it a day.
Primary use case would be PCPs who aren’t trained to diagnose skin cancer. There will be cost saving because the patient won’t have to visit a derm. Also it opens it up beyond dermatologists so it could be a PA or NP. That means in theory you could go to could go to a CVS minute clinic if you have suspicious mole.
I wonder what the liability will be if the machine misses a cancer and the PCP didn't refer them to a skin expert (eg, dermatologist).
Which will probably be billed at $200, if my long experience with dermatologists is any guide.
