What is the pre-determined amount of money paid by the patient before an insurance company pays?

A premium is a recurring amount paid by the patient or their employer to maintain insurance coverage. It is not a predetermined amount paid before insurance coverage.

  A co-pay is a fixed amount paid by the patient for each visit or service. It is not a predetermined amount paid before insurance coverage.

  An out-of-pocket maximum is the limit of the total amount of money the patient is responsible for paying for covered services. It is not a predetermined amount paid before insurance coverage.

  The deductible is the amount of money the patient is responsible for paying out of pocket before the insurance company begins to cover the cost of services. This is the predetermined amount referred to in the question. Once the deductible is met, the insurance company will then begin to cover a portion or all of the costs for the patient's covered services. Therefore, the correct answer is C Deductible.
