Final answer:
Patients with prior continuous health coverage are protected by HIPAA from being denied insurance due to preexisting conditions, which is termed 'Preexisting condition protection'. The ACA further enhanced this by prohibiting any denial of coverage to these individuals, leading to a significant decrease in the uninsured rate.
Step-by-step explanation:
The correct answer to the question is, patients with prior continuous health coverage cannot be denied due to preexisting conditions under HIPAA, is a) Preexisting condition protection.
The Health Insurance Portability and Accountability Act (HIPAA) was passed into law in 1996, ensuring that individuals with preexisting conditions who have had continuous coverage would not be denied insurance due to their health history. This protection was further strengthened by the Patient Protection and Affordable Care Act (ACA), also known as Obamacare, which mandated that people with preexisting conditions could no longer be denied health insurance. These legislative actions have significantly reduced the percentage of those without health insurance in the US and increased the number of Americans with coverage.
The ACA achieved substantial decreases in the uninsured rate, from 20.3% in 2012 to 8.6% by 2020. Additionally, the ACA's advancements supported employer and individual mandates, ensuring further expansion of healthcare coverage.
