In health insurance, who qualifies for services based on a relationship to the main subscriber?

In health insurance, dependents qualify for services based on their relationship to the main subscriber. Dependents typically include spouses, children, and sometimes other family members who are covered under the health insurance policy. This coverage allows them to access health services on the same terms as the primary member.

The reasoning behind this is that health insurance plans are designed to provide broad coverage to the family unit, ensuring that all members have access to necessary medical care. This system of including dependents in a health insurance plan recognizes the communal nature of family health needs and the responsibility of the primary policyholder for their dependents’ well-being.

Other groups mentioned in the options, such as healthcare providers and other insurance customers, do not qualify for health insurance services based solely on their relationship to the main subscriber. Healthcare providers offer services but are not insured under the subscriber's policy, while other customers are unrelated individuals who might have their own separate insurance coverage.
