Final answer:
Knowledge regarding the charge or price of a healthcare service is not enough information to determine the cost sharing amount. Additional factors such as deductibles, co-insurance payments, and co-payments also play a role.
Step-by-step explanation:
Knowledge regarding the charge or price of a healthcare service is not enough information to determine the cost sharing amount because cost sharing also depends on factors such as deductibles, co-insurance payments, and co-payments. A deductible is a fixed amount that insurance does not cover before paying benefits. Co-insurance payments are a percentage of the costs that individuals have to pay, while co-payments are fixed amounts for specific services. These additional factors affect the overall cost sharing amount and cannot be determined solely based on the charge or price of a healthcare service.
