<human>:  How does the Affordable Care Act (ACA) impact healthcare costs?
<bot>: The Affordable Care Act (ACA) requires health insurance companies to provide high-quality coverage to all insured individuals, and regulates how much companies can charge for insurance and health care services. This has helped to reduce the overall costs of healthcare, as it ensures that more people have access to insurance, and that they pay less for both insurance and healthcare services. Additionally, ACA has put into place preventive services and health care delivery system reforms that have helped to better manage the cost of health care and to reduce unnecessary spending.
