According to the Affordable Care Act, which of the following coverages is not required?

The Affordable Care Act (ACA) delineates essential health benefits that all qualified health plans must cover, which includes preventive care, maternity services, and mental health services. These essential health benefits are designed to ensure comprehensive healthcare coverage for individuals.

Cosmetic surgery, on the other hand, is typically considered non-essential because it does not address a medical necessity in the same manner as the other coverages listed. Such surgeries are generally elective and not required under the guidelines set forth by the ACA. This distinction is crucial because it emphasizes that while necessary medical services are mandated for coverage, elective procedures aimed at aesthetic enhancement do not fall under the requirements.

Therefore, the correct answer reflects the nature of coverage outlined in the ACA and how it categorizes various health services in terms of necessity and medical importance.
