The core reasons seems to be that you seem to keep misrepresenting my arguments.

I'm not talking about "practicing medicine" at all, just about who pays for what.

Ensuring patients are able to access the treatments ordered for them, or at least trying to do that, qualifies as part of the practice of medicine. That's why medical practices have billing departments to deal with insurance on the patient's behalf, rather than requiring cash up front and letting patients figure their own way through the reimbursement process.

The problem isn't that I'm misrepresenting your arguments, such as they are. The problem is that, instead of finding out how this stuff actually works and understanding why it works the way it does, you prefer to continue insisting on your opinions, which are as apparently uninformed as strongly held.

I don't see what you hope to achieve by this save wasting someone time, and my test suite just finished running, so it'll have to be someone else's time from here.

You're right, maybe I'm just unfamiliar with how health insurance works in the US.

In Europe, neither public nor private insurance covers beauty surgeries (at least the ones I'm familiar with).
