In medicine, all insurance related billing is done via codes: codes published by Medicare, and copied by virtually every other insurance company out there.

There are alphanumeric codes for diagnoses, level/complexity of an interaction/visit, and procedures. To get paid for something, a provider has to provide code(s) for the diagnosis and treatment, as well as proof (medical charting) of the service provided. So depending on the nature of the service provided, you'll either get paid by the diagnosis, the level of complexity of the visit (rated on a scale of 1-5), OR on the procedure that was performed. There are some modifiers which can alter the bill slightly, but nowhere is your declared specialty, level of experience, or background training taken into account in medical billing.
