If it's not medicine, why do they say the word "medical"? Why does the insurance company pay a doctor to do it, if they could pay someone cheaper to say those words? I'm not a doctor or lawyer, but if I had to guess, the answers are that the law requires it be a doctor exercising their medical training, while the company tries to hide behind arguments like this to get around the law.
Your guess would be wrong. At least at the federal level there is no such law. (It's possible that some states might have more stringent laws.)
