Final answer:
It is true that under the Affordable Care Act, individuals between the ages of 18 and 34 with pre-existing conditions cannot be denied coverage or charged higher premiums. The ACA has significantly increased health insurance coverage and decreased the uninsured rate among Americans.
Step-by-step explanation:
The statement that with The Affordable Care Act (ACA), 18-34 year olds with a pre-existing condition can no longer be charged higher premiums or denied coverage altogether is TRUE. One of the significant reforms under the ACA is that it mandated that people with pre-existing conditions, including young adults in the age bracket of 18 to 34, could not be denied health insurance coverage. As a result of the ACA, health insurance coverage significantly increased, and by 2020, the percentage of the uninsured population dropped to 8.6%.
Prior to the ACA, insurance companies used pre-existing conditions to charge higher rates or refuse coverage. The ACA addressed this issue by prohibiting such practices, thereby allowing millions of Americans to gain access to healthcare. This was part of a larger effort to counteract the rising healthcare costs and expand healthcare access to uninsured and underinsured individuals across the United States.
