Final answer:
The claim is false; the Affordable Care Act allows young adults to stay on their parents' health insurance plans until age 26, not 19.
Step-by-step explanation:
The statement that the Affordable Care Act allows young adults to continue on a parent's health insurance plan until age 19 is false. The correct provision of the Affordable Care Act, commonly referred to as Obamacare, allows young adults to stay on their parents' health insurance plans until they turn 26 years old.
This provision aims to help provide continuous health coverage for young adults as they transition into the workforce or higher education and may not have access to their own employer-sponsored health plans.
Moreover, the ACA is a pivotal piece of legislation that also broadens Medicaid coverage, prohibits insurance companies from denying coverage based on preexisting conditions, and seeks to reduce the number of uninsured or underinsured Americans.
