Catastrophic health insurance is a specific type of individual (non-group) health coverage defined under the Affordable Care Act.
Prior to the ACA, "catastrophic coverage" was a generic term that referred to any sort of health plan with high out-of-pocket costs and limited coverage for routine health needs. The ACA created catastrophic health plans as a new type of plan available in the individual market. As defined by the ACA, catastrophic plans are not available as employer-sponsored coverage.
Note that catastrophic plans are fully compliant with the ACA, which means they cover essential health benefits and cap enrollees' out-of-pocket costs.

Catastrophic plans: What They Cover and How They Work
Catastrophic plans serve as a financial safety net in case you have very high medical costs during the year. They also include the same fully covered preventive care benefits that all ACA-compliant plans provide, as well as three non-preventive office visits per year that are covered with copays, even if you haven't met your deductible yet.
And although most services are counted towards the deductible until you meet it, essential health benefits are covered on all catastrophic plans. Note that "covered" means that the costs count towards the deductible until you meet it, and then the health plan pays for the rest of your essential health benefits needs for the remainder of the year.
But other than specific preventive care and up to three non-preventive office visits, you have to meet your deductible before your catastrophic health plan will start to pay for your care. However, you will be able to pay the health plan's negotiated rates during this time, instead of having to pay the full amount that the medical provider bills.
The deductible on a catastrophic health plan is so high that most enrollees don't meet it in a given year. It's equal to the maximum out-of-pocket amount that's allowed under federal rules, so for 2025, it's $9,200. (For 2026, this will increase to $10,150.)
That means there's no coinsurance on catastrophic plans—once you hit the deductible, the plan will start to pay for 100% of your covered services for the rest of the year.
So if you do end up with a year where you have very high medical costs, your catastrophic plan will kick in and start to pay your expenses. And racking up more than $9,200 in medical costs (or whatever the limit is in a given year) is much easier than you might think it would be. Any sort of inpatient hospital care is almost guaranteed to get you there, and so are a lot of outpatient procedures.
Some employers offer "skinny" plans or "mini-meds" that aren't real major medical health insurance (for example, they only cover preventive care, or might only provide $10,000 worth of coverage). You might hear people refer to these plans as "catastrophic coverage" but that is not what they are. And indeed, they will not cover catastrophic health needs at all.
What Defines a Catastrophic Health Plan?
Catastrophic health insurance offered on the Affordable Care Act’s health insurance Marketplaces/exchanges (and outside the exchanges, purchased directly from insurance companies) has the following conditions:
- It limits who can enroll. Not everyone is eligible to buy a catastrophic plan.
- Premium subsidies (premium tax credits) can't be used to help pay the monthly premiums.
- It has a very high deductible, equal to the maximum allowable out-of-pocket limit. (The ACA requires the federal government to set a limit on how high health plans' out-of-pocket caps can be. It changes each year, so catastrophic health plans' deductibles change each year as well. In 2014, it was $6,350, but it will have grown to $10,150 by 2026.)
- It covers all of the ACA's essential health benefits, including certain preventive care with no out-of-pocket costs.
- It covers three non-preventive primary care office visits each year with a copay. Beyond that, including any specialist visits, the member pays for their own costs until the deductible is met.
The deductibles on catastrophic health plans tend to be much higher than the deductibles on other plans, although it's common to see bronze plans with similar out-of-pocket maximums and deductibles that are nearly as high.
(The actuarial value of a catastrophic plan has to be less than 60%, which can overlap with the actuarial value of a bronze plan. But bronze plans and catastrophic plans are not in the same pool for risk adjustment, which allows catastrophic plans to have lower premiums even with fairly comparable benefits.)
It's common to see bronze plans with slightly lower deductibles and then some level of coinsurance until the out-of-pocket maximum is reached, whereas the deductible on a catastrophic plan uses up the full out-of-pocket maximum.
Once you’ve paid enough out of your own pocket to meet the deductible, your catastrophic health insurance plan will start paying for 100% of your covered health care expenses, as long as you stay in-network and follow the plan's rules for things like referrals and prior authorization.
What’s a Covered Health Care Expense?
A catastrophic plan has to cover the same essential health benefits that all ACA-compliant individual market health plans have to cover. For example, it must cover medically necessary care like doctor visits, inpatient care, surgeries, blood tests, maternity care, mental health care, and substance abuse treatment. However, it won’t start paying for those benefits until you’ve paid your deductible.
There are two exceptions to that rule:
- Like other health plans, catastrophic health insurance must pay for certain preventive health care even if you haven’t paid your deductible. This includes things like your yearly flu shot, screening mammogram, well-woman visit, and contraception (but note that not all preventive health care is fully paid for—or even covered at all—by health insurance plans, including catastrophic plans).
- Catastrophic health plans must pay for you to see your primary care provider three times per year without having to pay the deductible first. But they can require you to pay a copay for these visits.
During the COVID public health emergency, catastrophic plans were allowed (but not required) to pay for telehealth services before the member had met their deductible. That flexibility ended with the end of the public health emergency, in May 2023.
Who Can Buy a Catastrophic Plan?
Only certain people qualify to buy catastrophic health insurance in the individual insurance market. You have to either be under the age of 30 or have a hardship exemption (which includes affordability exemptions) from the ACA's individual mandate penalty.
In 2018, the federal government expanded the list of circumstances that make people eligible for hardship exemptions, so more people became eligible to purchase catastrophic plans.
Although the federal penalty for being uninsured was eliminated after the end of 2018, an exemption is still necessary to buy a catastrophic plan if you're 30 or older.
Very few people enroll in catastrophic plans, due to the limited eligibility rules and the fact that premium subsidies cannot be used with catastrophic plans. In addition, there are some areas of the country where no insurers offer catastrophic plans.
During the open enrollment period for 2024 coverage, less than 0.3% of all Marketplace enrollees nationwide opted for catastrophic plans—fewer than 59,000 people, out of more than 21.4 million enrollees.
Cost
If you’re eligible for a premium subsidy to help you pay your monthly health insurance premiums, you can’t use that subsidy with a catastrophic health plan. You have to pick a bronze, silver, gold, or platinum plan to use the subsidy.
It's important to note here that premium subsidies are larger and more widely available through the end of 2025, as a result of the American Rescue Plan and Inflation Reduction Act.
Some bronze plans have deductibles nearly as high as catastrophic plans (and total out-of-pocket costs that are equal to those on catastrophic plans), but will not pay for non-preventive primary care visits before the deductible.
Although premium subsidies can't be used on catastrophic plans, a healthy young person who doesn't qualify for premium subsidies might find a catastrophic plan to be a better deal than a bronze plan.
Although bronze plans tend to have out-of-pocket maximums that are the same as catastrophic plans, the catastrophic plans are generally less expensive. This is due in large part to the fact that catastrophic plans are pooled separately for risk adjustment calculations.
Bronze plans tend to be selected by fairly healthy applicants, but that means the insurers with significant bronze plan enrollment generally have to send money (via the risk adjustment program) to insurers that tend to enroll less healthy people, who may select silver, gold, or platinum health plans.
But catastrophic plans, which also tend to be selected by young, healthy people, don't have to send risk adjustment money to balance out the risk in metal-level plans. This helps to keep prices lower for catastrophic plans.
Hidden Benefit of Catastrophic Health Insurance
Even if you don’t spend enough on health care to meet your catastrophic health plan’s deductible, you’ll still pay less on out-of-pocket medical expenses with a catastrophic plan than if you had no health insurance coverage at all.
A catastrophic plan can be an HMO, PPO, EPO, or POS plan. These plans all negotiate discounted rates with the doctors, hospitals, labs, and pharmacies that are in their network of providers. As a subscriber to the catastrophic health plan, you get the benefit of these discounted rates even before you’ve paid your deductible.
Here’s an example: Let’s say you haven’t met your catastrophic plan’s deductible yet. You injure your ankle and need an ankle X-ray. The billed charge for your X-ray is $200. Without your catastrophic health insurance, you’d have to pay $200 out-of-pocket.
Now let's say that the in-network discount rate for health plan members is $98. Since you’re a member of the health plan using an in-network X-ray facility, you’ll only have to pay the $98 discounted rate.
Catastrophic Health Insurance and High-Deductible Health Plans Are Not the Same Things
It’s easy to make the mistake of thinking that a catastrophic health insurance plan is the same thing as a high deductible health plan (HDHP). After all, a catastrophic plan has a high deductible, so it must be a high-deductible health plan, right?
Wrong. And in fact, there is zero overlap between the two: Catastrophic plans can never be HDHPs. A qualified HDHP is a very specific type of health insurance designed to be used with a health savings account (HSA).
If you enroll in a catastrophic plan, you will not be able to contribute to an HSA, since the plan is not an HDHP. And if you enroll in an HDHP, you will not get three primary care visits covered with copays, since HDHPs cannot provide those.
Summary
Although "catastrophic coverage" used to be a generic term that could refer to any plan with fairly high out-of-pocket costs and limited benefits for day-to-day medical expenses, that is no longer the case.
Catastrophic health plans are a specific category of individual health coverage created by the Affordable Care Act. These plans are available in the Marketplace/exchange and directly from insurance companies.
They can only be purchased by a person who is under 30 or eligible for a hardship exemption from the ACA's individual mandate. Premium tax credits (subsidies) cannot be used with catastrophic plans, so these plans are generally not a good option for a person who is subsidy-eligible.
Catastrophic plans, as defined by the ACA, have deductibles equal to the allowable annual maximum out-of-pocket limit (these change each year). Before the enrollee meets the deductible, the plan will only pay for certain preventive care, and will cover three primary care visits with copays. All other covered expenses will count toward the deductible until it is met.
Very few people enroll in catastrophic plans, mostly because of the limited eligibility and availability, and the fact that premium subsidies can't be used with catastrophic plans. But if you're not eligible for subsidies and have the option to purchase a catastrophic plan, you might find that it's less expensive than a bronze plan, while providing similar coverage.
