That's not what parent said. Sure, they arguably "know how pricing works". Their staff (or at least, their data systems) know about each patient's insurance. And hopefully, what physician services it covers. But I doubt that physicians themselves know that stuff. It's not what they focus on. In my experience, staff generally know how to code referrals for lab work and specialists so patients' insurance will cover it. But sometimes they screw up. So for example, I've been prescribed a testosterone supplement. But insurance won't cover testing for blood testosterone, level unless they use the right diagnostic code. Also for prostate-specific antigen checking. They have to code "enlarged prostate" in order to have it covered. There's another code for routine testing, but it isn't enough.
