Most places are 800-2500/year if you go cash.
Personally:
Initial cash visit. You get labs prior to the visit.
$400 to establish care, plan, etc.
Follow ups are $100-200 depending on complexity(time) and are required 1 month after first visit, then every 3 months.
I deal with some trt/hrt, but I do a significant amount of "general" medicine on these patients too...
