ACA plan vs Catastrophic
ACA Marketplace Plan and Catastrophic Marketplace plan solve the same problem in different ways. ACA Marketplace plans are comprehensive major-medical insurance that must cover the ten essential health benefits, cannot deny you or charge more for pre-existing conditions, and are the only option eligible for income-based premium tax credits. Depending on income and household size, subsidies can dramatically lower the premium — many enrollees qualify for plans at little or no monthly cost — which makes the Marketplace the default starting point for most people buying their own coverage. By contrast, Catastrophic Marketplace plans are ACA-compliant major medical options available to people under 30 or with a hardship exemption. They feature low premiums and very high deductibles, covering preventive care and three primary visits before the deductible in typical designs. Below we compare them on cost, coverage, eligibility, and who each one fits best — with sources you can check.
