According to the ACA in 2010, which of the following actions are insurance companies no longer able to do?

The Affordable Care Act (ACA), signed into law in 2010, implemented significant reforms aimed at expanding access to health insurance and improving healthcare affordability. One of the landmark provisions of the ACA was the prohibition against denying coverage for children based on pre-existing conditions. This means that insurance companies can no longer refuse to enroll children who have health issues that existed before the start of their insurance coverage.

This protection laid the groundwork for broader reforms, as the ACA later expanded these protections to apply universally, preventing insurers from denying coverage to individuals of any age for pre-existing conditions. This provision was particularly important as it aimed to ensure that vulnerable populations, such as children with chronic illnesses, could receive necessary medical care without facing discrimination from insurers.

In contrast, the other options address aspects of insurance practices that remain permissible. For example, although the ACA can limit the extent to which insurers can charge higher premiums based on age, it does not eliminate age as a factor entirely in pricing, as age-based pricing is still allowed within certain limits. Thus, the prohibition on denying coverage for pre-existing conditions is a core element that sets the ACA apart in its efforts to protect individuals seeking insurance.
