According to the ACA, older adults may be charged no more than how many times the premium of younger adults?

Under the Affordable Care Act (ACA), the guidelines stipulate that older adults can be charged no more than three times the premium of younger adults. This is designed to prevent age discrimination in health insurance pricing and to ensure that older individuals have access to affordable coverage.

This regulation is part of the broader effort to enhance equity within the health insurance market. By setting this limit, the ACA aims to balance the interests of insurance providers, who need to charge higher premiums to cover the anticipated higher healthcare costs for older adults, while also protecting consumers from excessive charges based solely on age. Therefore, the correct answer reflects the ACA's intention to maintain fairness in premium pricing among different age groups.
