Which of the following is an example of a pre-existing condition in health insurance?

A pre-existing condition in health insurance refers to any health issue or illness that existed prior to obtaining an insurance policy. When someone has a chronic illness diagnosed before the start date of their health insurance coverage, that condition qualifies as a pre-existing condition. This means the insurer is often allowed to consider this condition when determining coverage options, premiums, and exclusions.

In contrast, an accident that occurs after purchasing insurance does not fall under pre-existing conditions, as it happened post-coverage. Weight loss surgery that is covered by the policy typically implies that it is considered a new procedure and not a condition that existed prior to policy commencement. A new health issue that develops while the person is insured is also not considered pre-existing, as it occurs after the policy is in place. Therefore, the option indicating a chronic illness diagnosed before the policy begins accurately exemplifies a pre-existing condition.
