An ACA catastrophic health plan is a distinct plan type available only to adults under 30 years old or to individuals of any age who have received a qualifying hardship or affordability exemption from the Marketplace. Catastrophic plans carry lower monthly premiums than Bronze plans and a deductible equal to the ACA out-of-pocket maximum, which CMS set at $9,450 for individual coverage in 2026. Three primary care visits per year and all ACA-required preventive services are covered before the deductible applies. Everything else accumulates toward it.
Key Takeaways
- An ACA catastrophic plan is a distinct plan type available only to adults under 30 or to those with a qualifying hardship or affordability exemption. They are not a Bronze plan. They do not appear in standard quote results for clients who do not qualify.
- Catastrophic plans cover three primary care visits per year and all ACA-required preventive services before the deductible. Everything else applies toward the deductible, which equals the ACA out-of-pocket maximum ceiling: $9,450 for individuals in 2026.
- CSR cannot be applied to catastrophic plans under any circumstances. APTC can be applied only by clients who qualify via a hardship or affordability exemption, not by the under-30 route.
- A Bronze HDHP frequently beats a catastrophic plan on net cost once APTC is factored in, because APTC reduces the Bronze premium but cannot offset the catastrophic premium for most under-30 enrollees.
- A client who turns 30 before January 1 of the coverage year is not eligible for a catastrophic plan for that year. Eligibility is based on age at the start of the plan year, not at enrollment.
Two paths to catastrophic plan eligibility
Eligibility for a catastrophic plan follows one of two separate tracks and the rules differ between them.
Age-based eligibility. A client is eligible if they are under 30 years old on the first day of the plan year. A client who turns 29 before January 1 can enroll in a catastrophic plan for that year. A client who turns 30 before January 1 is not eligible, even if they are 29 at the time of enrollment during OEP. The Marketplace checks the age at the start of coverage, not at the enrollment application date.
Hardship or affordability exemption. Adults of any age can access catastrophic plans if the Marketplace determines they qualify for an approved hardship category, or if all available Marketplace plans are unaffordable (meaning the lowest-cost Bronze plan exceeds a set percentage of household income). The client receives an exemption certificate number that must be entered during enrollment. Common hardship categories include homelessness, substantial debt from medical expenses, domestic violence situations, and natural disaster-related financial disruption.
What catastrophic plans cover and what they do not
All ACA essential health benefits are covered on catastrophic plans. The distinction is when the plan starts paying. Three primary care visits per year are covered at the regular cost-sharing rate before the deductible. All ACA-required preventive services, including annual wellness visits, screenings, and recommended vaccines, are covered at no cost before the deductible. For everything else, the client pays the full allowed amount until they have met the $9,450 individual deductible.
On a catastrophic plan, the deductible and the out-of-pocket maximum are the same number. Once the client meets the deductible in a plan year, the plan covers 100 percent of additional covered costs. There is no coinsurance layer between the deductible and the OOPM, which differs from Bronze and Silver plans where the client typically pays coinsurance after meeting the deductible until a separate OOPM is reached.
The APTC and CSR interaction: the part brokers get wrong
CSR is not available on catastrophic plans under any circumstances. Cost-sharing reductions apply to Silver plans only. A client who qualifies for CSR based on income cannot receive that benefit on a catastrophic plan, regardless of how low their premium is. For income-eligible clients, this matters: a Silver 94 CSR plan often has a lower effective deductible than a catastrophic plan even though the Silver gross premium is higher.
APTC is more nuanced. The credit is available on catastrophic plans only for clients who qualify via the hardship or affordability exemption route. An under-30 client who qualifies for APTC based on income cannot apply that credit to a catastrophic plan. They receive the same APTC amount as usual and can apply it to any metal-tier plan. This is the counterintuitive rule that changes the comparison most often.

Catastrophic vs Bronze HDHP: run the comparison
For most under-30 clients who qualify for APTC, the Bronze HDHP is the lower-cost option on a net premium basis, even though catastrophic plans have the lowest gross premiums. The reason: APTC reduces the Bronze premium, but an under-30 client cannot apply that credit to catastrophic.
To illustrate: a 26-year-old with projected income at 250 percent FPL might qualify for $180 per month in APTC. A Bronze HDHP grosses at $220 per month. Net after APTC: $40 per month. A catastrophic plan grosses at $155 per month. Net after APTC: $155 per month (credit cannot be applied). The Bronze HDHP wins by $115 per month, and it also qualifies the client for HSA contributions.
Illustrative example. Actual premiums and APTC depend on rating area, plan year, and household income. Run a live quote before advising.
Bronze HDHPs that qualify for HSA contributions add a further advantage for under-30 clients with any income who can set aside pre-tax dollars for healthcare. For how HSA eligibility works with ACA Bronze plans, read HSA and ACA Marketplace plans: what brokers need to know.
When catastrophic makes sense
Catastrophic plans are the right conversation for a narrow client profile. The clearest case is an under-30 client who does not qualify for APTC (income above the subsidy range), has very low expected healthcare utilization, and values the lowest possible monthly premium. The three free primary care visits per year cover a basic needs tier, and the HSA-eligible structure adds tax efficiency for the right client.
The second case is a hardship-exempt client of any age whose income situation changes the calculus. For a client who qualifies for the affordability exemption and also qualifies for APTC through the exemption route, catastrophic with APTC applied may compete with Bronze on net premium. This case is less common but worth checking when the circumstances arise.
The case it does not make: an income-eligible under-30 client who expects to use healthcare. A $9,450 deductible before the plan pays is a significant exposure for a client who visits specialists, takes regular medications, or is managing an ongoing condition. The low premium disappears quickly against one unplanned medical event.
FAQ
Questions brokers and clients ask about ACA catastrophic health plans.
Can a client use APTC on a catastrophic plan?
Only in limited cases. APTC can be applied to a catastrophic plan if the enrollee qualifies via a hardship or affordability exemption, not simply by being under 30. For the vast majority of under-30 enrollees, APTC is not available on catastrophic plans. This is the most counterintuitive aspect of catastrophic plan eligibility. A 27-year-old who qualifies for $250 per month in APTC cannot apply that credit to a catastrophic plan. They can apply it to any Bronze, Silver, Gold, or Platinum plan instead.
What is the deductible on an ACA catastrophic plan?
The catastrophic plan deductible equals the ACA out-of-pocket maximum ceiling set by CMS each year. For 2026, that is $9,450 for individual coverage and $18,900 for family coverage. Three primary care visits per year and all ACA-required preventive care are covered without applying this deductible. All other covered services accumulate toward the deductible before the plan pays. The deductible and the out-of-pocket maximum are the same figure on a catastrophic plan, which differs from other plan types where cost-sharing continues as coinsurance after the deductible until the separate OOPM is reached.
Is a catastrophic plan HSA-eligible?
Most ACA catastrophic plans qualify as high-deductible health plans (HDHPs) because their deductible exceeds the IRS minimum threshold for HDHP status. Enrollees who meet the IRS HDHP definition can contribute to an HSA while on a catastrophic plan. The IRS HDHP thresholds and the ACA OOPM limits are separate calculations, and the overlap means catastrophic plans typically qualify. Confirm HSA eligibility with the specific carrier plan documentation before advising a client to open an HSA account, since plan design details vary.
What qualifies as a hardship exemption for catastrophic plan access?
CMS recognizes several hardship categories that open catastrophic plan eligibility for adults of any age. These include domestic violence or abuse, homelessness, bankruptcy or substantial debt from medical expenses, the death of a close family member, a natural disaster that damaged the home or caused major financial disruption, a tribal enrollment qualifying event, and a determination that all available plans are unaffordable (meaning the lowest-cost Bronze plan exceeds a threshold percentage of household income). Brokers should document the specific exemption category when enrolling a client over 30 on a catastrophic plan. CMS requires the exemption certificate number at enrollment.
How does a catastrophic plan appear in a quote workflow?
Catastrophic plans only appear when the enrollee has been confirmed as eligible, either through age verification in the Marketplace application or through a hardship exemption certificate. In standard quoting workflows without the under-30 flag or exemption entered, catastrophic plans are not displayed in results. Brokers using integrated enrollment platforms like Inshura or submitting directly through Healthcare.gov will see catastrophic options populate once the age or exemption criteria are entered. If a client claims they want the cheapest possible plan and asks about catastrophic, the first question is whether they qualify; if not, the lowest-cost Bronze HDHP is the correct starting point.
