Which term describes a complete lack of coverage for a medical condition?

The term that describes a complete lack of coverage for a medical condition is "exclusion." Exclusions in a health insurance policy refer to specific conditions or situations that are not covered by the policy. When a condition is excluded, it means that the insurer will not provide benefits or payment for any medical expenses related to that particular condition. This could be due to various reasons such as the insurance company deeming it too risky or because it falls outside the scope of the policy's coverage.

In contrast, a deductible is the amount that a policyholder must pay out-of-pocket before their insurance begins to cover costs. Co-insurance refers to the percentage of costs that a policyholder must pay after the deductible has been met. A premium is the amount paid to maintain the insurance policy itself, typically on a monthly basis. Therefore, only exclusion correctly identifies a scenario where there is no coverage at all for a specific medical condition.
