The short answer
Catastrophic health plans are low-premium, high-deductible ACA plans meant to protect against worst-case medical costs. But they have a catch: not everyone can buy one. They're generally limited to people under 30, or to people 30 and older who qualify for a hardship or affordability exemption. For those who qualify and are healthy, they can be a low-cost safety net.
So a catastrophic plan is a niche option gated by eligibility, not a plan anyone can simply choose.
Who qualifies
Two groups can buy catastrophic plans: anyone under 30, and people 30 or older who have a hardship or affordability exemption (for example, if other coverage would cost more than a set share of income). If you're over 30 without an exemption, you generally can't enroll in one. Our guide to catastrophic plans for under-30s covers the younger group in detail.
Also note: subsidies generally don't apply to catastrophic plans, so if you qualify for a large subsidy, a Bronze or Silver plan may actually cost less after the credit.
When they make sense
A catastrophic plan can make sense for a healthy young person, or a qualifying older person, who wants the lowest premium and mainly protection against a serious event, and who doesn't qualify for a subsidy that would make a Bronze or Silver plan cheaper. You get essential health benefits and free preventive care, but a high deductible for most other care. Our individual health insurance overview covers the alternatives.
The takeaway: check eligibility and compare against a subsidized Bronze or Silver plan, which often wins if you qualify for help.
