How will a pre-existing conditions exclusion affect Karen's new insurance contract?

A pre-existing conditions exclusion in an insurance contract means that the insurance company may limit or exclude coverage for health issues that existed before the start date of the new policy. In Karen’s case, if she has a pre-existing condition, the exclusion could lead to a reduction in benefits for treatment related to that condition. This is because the insurer may choose to only partially cover costs associated with that condition, or include waiting periods before coverage for those specific conditions kicks in.

In many cases, insurers implement such exclusions to mitigate the risk of insuring individuals with existing health issues, as these can result in higher costs. Therefore, it’s plausible to conclude that Karen’s new insurance would either outright deny coverage for her pre-existing condition, which is one possibility, but more commonly it would result in a reduced level of benefit provided for that condition. This interpretation aligns with the option indicating a reduction in her benefits, as opposed to having either full benefits, the exclusion being inapplicable, or complete denial of coverage, which might not accurately reflect how such exclusions typically function.
