Final answer:
New York's group accident and health insurance policies must include unmarried dependent children up to 26 years old. This complies with the Affordable Care Act's provisions to extend health coverage, with Medicaid being available more broadly and the introduction of state-based insurance purchasing organizations.
Step-by-step explanation:
Group accident and health insurance policies issued in New York must generally include an unmarried dependent child who is 26 years old or younger. This is in accordance with the Affordable Care Act, which expands coverage and subsidies for Medicaid and introduces new insurance purchasing organizations through which individuals can buy coverage. Insurance companies are not allowed to reject individuals for preexisting conditions, and lifetime limits on insurance payments have been removed.
In the context of health insurance for various age groups provided by the government, it is important to note that other programs exist for specific groups such as those over age 65, military veterans, and children in families with relatively low incomes.
