Medicial Coding is done the same way. The clinic where my wife works employes a medicial coder full time. Her staff has to constantly call Medicare and insurance companies all the time. I got out of cable to work on a medical coding certification. It is a way to not pay. At least that is the way it works in the medicial industry.
