18. When a policy claim contains a deductible and a coinsurance provision, the policyholder's portion of the claim is calculated by:

Answer: B

Explanation:

The policyholder's portion of the claim is calculated by applying the deductible first.

In a policy that includes both a deductible and a coinsurance provision, the policyholder's financial responsibility begins with the deductible. This means that the policyholder must pay the deductible amount before any coinsurance calculations are made.

A) Applying the coinsurance percentage first.

This option is incorrect because the coinsurance percentage is only applied after the deductible has been satisfied. The purpose of the deductible is to reduce the amount of the claim that the insurance company will cover, so it must be addressed initially.

B) Applying the deductible first.

This option is correct as it reflects the standard process in insurance claims where the deductible amount is subtracted from the total claim before any coinsurance calculations take place. Therefore, the policyholder's portion of the claim is effectively determined after this initial reduction.

C) First applying the higher of the coinsurance percentage or the deductible.

This option is incorrect because it misrepresents how deductibles and coinsurance work in conjunction. The deductible is a fixed amount that must be paid first, and coinsurance is a percentage of the remaining amount, not a comparison between the two.

D) First applying the lower of the coinsurance percentage or the deductible.

This option is also incorrect as it suggests that there is a choice between applying the deductible or the coinsurance percentage based on which is lower. The deductible must always be applied first, regardless of its relation to the coinsurance percentage.

Conclusion

Applying the deductible first is essential in determining the policyholder's portion of the claim, as it establishes the initial out-of-pocket expense before any insurance calculations for coverage take place. The other options fail to recognize the correct order of operations in such claims, making them incorrect. Understanding this process is crucial for policyholders to accurately assess their financial responsibilities in the event of a claim.
