What is Short-Term Health Insurance
Short-term health insurance is a temporary, limited health coverage plan designed to bridge gaps in coverage — such as between jobs or during a waiting period — typically lasting 1 to 12 months, with lower premiums but significant coverage limitations.
Short-term health insurance (also called short-term limited-duration insurance or STLDI) is temporary health coverage that fills gaps when you're between plans — between jobs, aging off a parent's plan, or waiting for employer benefits to begin. These plans offer lower premiums than ACA-compliant plans but come with significant trade-offs in coverage, consumer protections, and financial risk.
When People Turn to Short-Term Coverage
Short-term health insurance is typically sought during:
- A gap between jobs with no COBRA coverage or when COBRA is too expensive
- Waiting for employer benefits to begin (many employers have 30–90 day waiting periods)
- Aging off a parent's plan at 26 and not yet employed with benefits
- Early retirement before Medicare eligibility at 65
- Missing open enrollment for an ACA marketplace plan
What Short-Term Plans Cover
Short-term plans are not ACA-compliant. They are not required to cover the ACA's 10 essential health benefits, meaning many plans:
- Do not cover pre-existing conditions
- Do not cover mental health or substance use treatment
- Do not cover maternity care
- Do not cover prescription drugs (or offer very limited coverage)
- Can cap annual or lifetime benefits
The coverage that is typically included: emergency care, hospitalization, physician visits, and sometimes basic preventive care — though benefit structures vary widely between carriers.
Short-Term vs. ACA Marketplace Plans
| Feature | Short-Term Plan | ACA Marketplace Plan |
|---|---|---|
| Pre-existing conditions | Often excluded | Must cover |
| Essential health benefits | Not required | All 10 required |
| Annual/lifetime limits | May apply | Prohibited |
| Deductibles | Often high | Regulated |
| Subsidy eligibility | No | Yes (if eligible) |
| Duration | 1–12 months (varies by state) | Annual, renewable |
| Cost | Lower premiums | Varies; subsidies available |
Premium Costs
Short-term plans are significantly cheaper than ACA plans in many cases — a healthy 30-year-old might pay $100–$200/month for a short-term plan versus $300–$500+ for an unsubsidized ACA bronze plan. However, if you qualify for ACA subsidies (premium tax credits), the actual cost of a marketplace plan may be comparable or even lower.
Always check marketplace subsidy eligibility before defaulting to a short-term plan. If your income is between 100–400% of the federal poverty level (or higher, in some years), you may be entitled to substantial premium subsidies.
The Hidden Costs and Risks
Short-term plans deny claims in ways ACA plans cannot:
- A pre-existing condition exclusion can turn a $40,000 hospital bill into your full financial responsibility
- Some plans rescind (cancel) coverage retroactively after a claim if undisclosed conditions are found in your application
- Annual benefit caps can leave you with large out-of-pocket costs after serious illness or injury
- Out-of-pocket maximums may not apply
State Regulations
Short-term plan rules vary significantly by state:
- Some states (California, New York, Massachusetts, others) prohibit or severely restrict short-term plans
- Other states allow plans up to 12 months, renewable for up to 36 months total
- Federal rules (which changed in 2024) may limit initial terms — always check current rules for your state
Better Alternatives to Consider First
- COBRA insurance: Extends your employer plan; expensive but full ACA-compliant coverage
- ACA marketplace plan: Losing job-based coverage qualifies you for a Special Enrollment Period; check subsidy eligibility
- Medicaid: If your income drops significantly, you may qualify for free or low-cost Medicaid
- Spouse's or partner's plan: Job loss often qualifies you as a Special Enrollment event on a spouse's employer plan
Short-term plans serve a narrow use case — a truly temporary gap where cost is paramount and you're in good health. For most situations, exploring ACA marketplace options with subsidy analysis is the more financially prudent choice.
