PCP is certainly not going to be the one doing the colonoscopy.
maybe they’d do the stool sample or some silly blood test if you are extremely insistent and can somehow demonstrate a risk factor.
I’ve dealt with a few PCPs and they seem less informed about their own area than a 30 sec google search.
They’re basically L6 tech support…
I read here (on Hacker News) that the stool test is actually really valuable and cheap enough to pay out of pocket prior to trying to justify an out-of-schedule colonoscopy.
