According to the Affordable Care Act, which date marks the cut-off for grandfathered plans?

The correct answer is March 23, 2010, as this date is significant because it marks the enactment of the Affordable Care Act (ACA). Under this legislation, health plans that were in existence on this date could qualify as "grandfathered plans." This means they could retain certain pre-existing features without having to comply with all the ACA provisions that apply to new health plans. Grandfathered plans are exempt from some ACA requirements, as long as they do not make significant changes that would cause them to lose that status. Understanding this cut-off date is vital for consumers and insurers alike, as it impacts the rights and protections homeowners have under their health insurance coverage.
