Step-by-step explanation:
When an insurance carrier has denied payment for a procedure that did not get prior authorization, the service is typically billed to the patient for the full fee. This means that the patient is responsible for paying the entire cost of the procedure out of pocket. The insurance carrier does not contribute any payment towards the procedure since it was not authorized beforehand.
