Sorry, but I am compelled to add my 2 cents...

I worked in medical billing in both a psychiatry practice and a medical practice. I was the only person who EVER talked directly to the insurers. Not a single time did one of the docs ever get on the horn and talk to them. When a prior authorization was required, it was me who did the paperwork and legwork, the docs just signed the forms.

In the years I worked in billing, there was never a single case of an insurer letting us know a patient was seeing multiple doctors or receiving medications elsewhere. So I agree 100% with the previous poster that the label is given by the physician and generally doesn't get much farther than that practice unless records travel to a different doctor.
