Deductible: The amount you must pay for medical treatment before your health insurance company starts to pay. Co-Insurance: The part of your bill, often in addition to your co-pay, that you must pay. It is usually a percentage of the total medical bill. Co-payment “Co-pay”: The part of your medical bill you must pay each time you visit the physician. This is a pre-set fee determined by your health insurance policy. In-Network: The physician has a contract with the health insurance company to provide you with medical care. Out-of-Network: The physician is not contracted with the health insurance company to provide you with medical care.
