Age can be a factor in health insurance eligibility in various contexts. For instance, children under the age of 26 are eligible to be covered under their parents’ health insurance plans, even if they’re no longer a tax dependent, if they’re eligible for other health insurance through their employer, or if they’re married. For older individuals, eligibility for Medicare starts typically at age 65.
Under the Affordable Care Act, health insurance providers cannot deny coverage based on age, though older individuals might pay more if the group is age rated.
