Catastrophic Health Insurance in 2027: Who Qualifies?
Answer first: A 2027 catastrophic Marketplace plan can be purchased when it is available locally and the enrollee is under age 30 or has an approved hardship or affordability exemption. HealthCare.gov lists the 2027 affordability test as more than 8.5% of household income for the lowest-priced available coverage. The lower premium is not automatically the cheapest total choice: premium tax credits cannot be used on catastrophic plans, and the deductible is intentionally high.
What a catastrophic plan covers
Catastrophic plans are Affordable Care Act qualified health plans designed around a low-premium, high-deductible structure. They still cover the ACA's essential health benefits and cannot exclude a person for a pre-existing condition. Federal rules also require preventive services without cost sharing and at least three primary-care visits before the deductible is met.
Most other nonpreventive care is paid by the member until the deductible is reached. After that, the plan pays according to its benefits and network rules. “Catastrophic” describes the cost-sharing design; it does not mean the plan covers only hospital catastrophes.
Three ways to qualify in 2027
1. You are under 30
A person who has not attained age 30 before the first day of the plan year can enroll without an exemption, if a plan is sold in the service area. Availability varies by county and issuer.
2. Coverage fails the affordability test
HealthCare.gov says the 2027 affordability exemption applies when the lowest-priced Marketplace or job-based coverage available costs more than 8.5% of household income. The application requires income and coverage documentation. This exemption is not automatic simply because a premium feels expensive.
3. You receive a hardship exemption
Recognized hardships can include homelessness, eviction or foreclosure, bankruptcy, a utility shut-off notice, substantial disaster damage, domestic violence, unpaid medical expenses, death of a close family member, and certain caregiving-cost increases. CMS also expanded policy for people ineligible for advance premium tax credits or cost-sharing reductions because projected income falls below 100% or above 250% of the federal poverty level and they experience an income change.
Unemployment by itself is not automatically a hardship, according to HealthCare.gov. Explain the actual qualifying circumstance and provide requested evidence.
The 8.5% affordability test in dollars
Multiply projected annual household income by 0.085, then divide by 12 for a rough monthly threshold. The official determination uses Marketplace rules and the actual lowest-priced available coverage, so these examples are screening tools only.
| Projected household income | 8.5% annual amount | Approximate monthly amount |
|---|---|---|
| $30,000 | $2,550 | $212.50 |
| $50,000 | $4,250 | $354.17 |
| $80,000 | $6,800 | $566.67 |
| $120,000 | $10,200 | $850.00 |
Household income for Marketplace purposes is generally modified adjusted gross income for the tax household, not take-home pay. Changes in wages, self-employment income, unemployment compensation, household members or employer coverage can alter the result.
Catastrophic versus Bronze: compare net cost
CMS says the lowest-cost catastrophic premium available for 2027 averages nearly 10% less than the next-lowest plan at other metal levels. That national statement is not a quote for your ZIP code. More importantly, premium tax credits cannot be used to buy catastrophic coverage. A Bronze plan with a tax credit can therefore have a lower net premium than an unsubsidized catastrophic plan.
| Question | Catastrophic | Bronze |
|---|---|---|
| Premium tax credit usable? | No | Yes, if eligible |
| Cost-sharing reductions? | No | No; CSRs require an eligible Silver plan |
| Three pre-deductible primary-care visits? | Required | Depends on plan design |
| Best comparison figure | Full premium + expected out-of-pocket cost | Net premium after credit + expected cost |
If you qualify for cost-sharing reductions, compare Silver before either option. Those reductions can lower deductibles, copays and the out-of-pocket maximum only when enrolled in a qualifying Silver plan.
What changed for 2027
The 2027 federal rule codified broader hardship access and permits catastrophic plans to use plan terms of one year or multiple consecutive years, up to ten years, under specified standards. A multi-year term does not mean the premium, provider network or every plan feature is frozen for a decade. Read renewal and change notices each year.
The rule also allows certain value-based insurance designs in multi-year catastrophic plans, subject to federal guidance. Consumers should compare the actual Summary of Benefits and Coverage rather than assuming every catastrophic product has identical pre-deductible benefits.
How to apply for an exemption
- Preview plans. Confirm a catastrophic plan is actually offered for your ZIP code.
- Choose exemption type. Use affordability or the hardship category that matches your facts.
- Gather documents. Income records, employer-offer information, eviction notices, disaster records or a written explanation may be needed.
- Submit early. HealthCare.gov says people seeking next-year coverage should apply before January 1.
- Use the ECN. If approved, the Marketplace sends an Exemption Certificate Number used to enroll.
California, Connecticut, the District of Columbia and Maryland use their own exemption processes. Follow the state Marketplace instructions shown by HealthCare.gov.
Network, prescriptions and HSA checks
A low premium can be false economy if your physician, hospital or medication is not covered as expected. Search the current provider directory, then call important providers and the insurer. Check the formulary tier, prior-authorization rules, specialty-drug coinsurance and whether out-of-network care is covered beyond emergency protections.
For an HSA, verify the specific plan is identified as HSA-eligible and confirm you have no disqualifying other coverage. The 2027 HSA limits guide explains contribution rules. An HSA can help with qualified expenses, but it does not turn a high deductible into affordable care if you cannot fund the account.
A seven-point decision checklist
- Compare the catastrophic full premium with each metal plan's net premium.
- Add expected prescriptions, therapy, specialist visits and planned procedures.
- Check the deductible and individual/family out-of-pocket maximum.
- Verify doctors, hospitals, urgent care and pharmacies.
- Test whether one emergency could be paid from savings.
- Confirm exemption and HSA eligibility separately.
- Save plan documents and enrollment confirmation.

Frequently asked questions
Who can buy a catastrophic health plan in 2027?
You may qualify if a catastrophic plan is offered in your area and you are under 30, or if you receive an approved hardship or affordability exemption. Each person enrolling in family coverage must independently meet the eligibility rule.
What is the 2027 affordability-exemption threshold?
HealthCare.gov states that coverage is considered unaffordable for this exemption when the lowest-priced available Marketplace or job-based option costs more than 8.5% of household income in 2027.
Do catastrophic plans cover preventive care?
Yes. Federal rules require specified preventive services without cost sharing, and catastrophic plans cover at least three primary-care visits before the deductible. Other covered care generally faces the high deductible first.
Can premium tax credits pay for a catastrophic plan?
No. Marketplace premium tax credits cannot be applied to catastrophic-plan premiums. A subsidized Bronze or Silver plan may therefore cost less and offer better cost sharing.
Are 2027 catastrophic plans HSA eligible?
Plan design and federal HSA rules must both be satisfied. Do not assume eligibility from the word catastrophic; confirm the plan is labeled HSA-eligible and verify your other coverage does not disqualify contributions.
When is 2027 Marketplace open enrollment?
For HealthCare.gov, 2027 open enrollment runs November 1, 2026 through January 15, 2027. State-based Marketplaces may use different deadlines.
