ACA plan vs Catastrophic
ACA Marketplace Plan and Catastrophic Health 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 plans are ACA-compliant plans with very low premiums and very high deductibles, available only to people under 30 or those with a qualifying hardship or affordability exemption. They cover the essential health benefits and three primary-care visits before the deductible, plus free preventive care — but you pay for most other care out of pocket until you hit the deductible. They function as worst-case protection for young, healthy people. Below we compare them on cost, coverage, eligibility, and who each one fits best — with sources you can check.
