The one wildcard with outpatient services is the coinsurance. Coinsurance is a percentage of the invoiced services that the health plan member is responsible for. For outpatient procedures, the coinsurance is not subject to the medical deductible for Silver plans. However, you may find yourself getting billed for coinsurance when you thought the health service had just a set copayment. For example, imaging with the injection of a dye to enhance image contrast. The machine imaging scan will have a set copayment, but the injection of the dye is considered an outpatient procedure subject to coinsurance.
