Which of the following categories of medical insurance are not APTC eligible?

Catastrophic plans are specifically designed to provide a safety net for individuals who are generally healthy and do not expect to incur significant medical costs. These plans have lower monthly premiums but come with high deductibles, which means that they are intended for worst-case scenarios rather than regular healthcare needs.

One key aspect of Catastrophic plans is that they are not eligible for Advanced Premium Tax Credits (APTC). APTC is a subsidy that helps lower-income individuals afford health insurance through the Health Insurance Marketplace. In contrast, Gold, Silver, and Bronze plans are all eligible for APTC because they offer a broader range of coverage and can cater to individuals who might not be able to afford premiums without assistance. This makes the choice of Catastrophic plans distinct, as they are excluded from APTC eligibility due to their specific target demographic and structure.
