Under the recent legislation, guaranteed insurance issue for children applies to those under what age?

The correct answer is that guaranteed issue of health insurance for children applies to those under age 19. This aligns with provisions from various health reform laws, notably the Affordable Care Act, which stipulates that children can obtain coverage without being denied due to pre-existing conditions up until they reach their 19th birthday.

This guarantee allows families peace of mind, ensuring that children have access to necessary health services and coverage, thereby promoting preventive care and overall well-being. This age limit reflects the understanding that young individuals are still developing and may encounter health issues that necessitate insurance coverage.

In the context of the options provided, the ages 20 and 21 exceed the age limit for children's guaranteed issue coverage. Thus, while the coverage continues into adulthood, young adults above these ages do not qualify for guaranteed issue under the same provisions aimed explicitly at children.
