Final answer:
A medical assistant should verify the patient's insurance coverage before referring them to another facility.
Step-by-step explanation:
Before referring a patient to another facility, a medical assistant should be sure to verify the patient's insurance coverage. This is important because insurance coverage determines whether the patient will be able to receive the necessary treatment at the referred facility. By verifying insurance coverage, the medical assistant can ensure that the patient will not face any financial difficulties or unexpected costs.
