Final answer:
If more than one doctor is treating a patient, the patient's primary physician is responsible for coordinating the care and evaluations of all the doctors involved.
Step-by-step explanation:
If more than one doctor is treating a patient, the patient's primary physician is responsible for coordinating the care and evaluations of all the doctors involved. This primary physician is typically assigned by the patient's insurance company or chosen by the patient themselves. The primary physician does not need to assign authorization to other doctors unless it is required by the insurance company or if there are specific procedures or treatments that need approval.
