Which term refers to the percentage of the total healthcare cost that a patient is responsible for after insurance has paid its share?

The term that refers to the percentage of the total healthcare cost that a patient is responsible for after insurance has paid its share is coinsurance. Coinsurance is a cost-sharing arrangement where the insured individual pays a certain percentage of healthcare costs, while the health insurance company covers the rest. For instance, if a patient has a coinsurance rate of 20%, after the insurance has paid its portion, the patient will be responsible for 20% of the remaining costs.

Understanding coinsurance is crucial for patients as it directly affects out-of-pocket expenses for medical services. Unlike a deductible, which is the amount a patient pays before insurance starts covering costs, or a copayment, which is a fixed amount paid for specific services, coinsurance involves a percentage that can vary based on the type of service received.

Additionally, an out-of-pocket maximum is the maximum amount a patient will spend in a given year before their insurance covers 100% of covered expenses. While all these terms relate to healthcare costs, coinsurance specifically addresses the shared cost percentage that follows insurance coverage. Therefore, the correct answer highlights an essential aspect of patient responsibility in healthcare financing.
