An insurance exam has to be impartial and provide objective information relative to risk assessment. Often a personal doctor is a patient advocate- and wants the client to do well. So do insurance companies, but with all the accurate information needed to make a fair decision. Additionally, a client can ask a personal doctor not to disclose certain information (doctor-patient privilege), which may be a conflict of interest for the doctor to act as both an agent for the company and the potential insured.
