In Ariana's scenario, after excluding her deductible, what will the insurance company pay of the remaining bill?

In an insurance context, the portion of the bill that the insurance company pays after the deductible is applied is referred to as the coinsurance rate. If Ariana's insurance plan specifies that the company covers 80% of the costs after the deductible is met, it means that she is responsible for the remaining 20%. This structure is designed to share the costs of healthcare between the insurer and the insured, encouraging individuals to be more mindful of their healthcare spending while still providing significant coverage.

In this case, since the correct choice is 80%, it suggests Ariana's plan offers solid coverage, typical of many health insurance policies. The coinsurance is a percentage applied to the costs beyond the deductible; since many plans have coinsurance rates of commonly 80% or 90%, this fits within standard industry practice. Understanding how deductibles and coinsurance work helps individuals gauge their potential out-of-pocket expenses and plan their finances accordingly.
