Is Short-Term Health Insurance Worth It? Costs and Risks

Short-term health insurance can cost less per month than a Marketplace plan or COBRA, but it is cost-effective only for healthy people with a brief, predictable coverage gap. These plans can exclude pre-existing conditions, skip essential health benefits, cap payouts and deny applicants based on health, so one serious illness can erase the premium savings.

Key takeaways

  • Short-term, limited-duration insurance (STLDI) is not ACA-compliant coverage and does not count as minimum essential coverage.
  • A 2024 federal rule limited new plans to a three-month term and four months total, but federal agencies said in 2025 they would not prioritize enforcing it while they revisit the rules.
  • State law still controls availability: some states ban or effectively block these plans.
  • Compare total expected cost, including excluded care, not just the monthly premium.

What is short-term health insurance?

STLDI is a type of health coverage designed to fill temporary gaps, such as the weeks between jobs or before employer coverage starts. Because it is excluded from the federal definition of individual health insurance coverage, it is generally exempt from Affordable Care Act market rules. According to healthinsurance.org, that means short-term plans:

  • Are not required to cover essential health benefits such as maternity care, mental health or prescription drugs.
  • Are not required to cover pre-existing conditions.
  • Can use medical underwriting to set eligibility and premiums.
  • Can impose annual or lifetime benefit caps.
  • Do not count as minimum essential coverage, and the end of a short-term plan does not trigger a Marketplace special enrollment period.

What are the current federal rules on short-term plans?

The rules have changed several times. A 2018 rule allowed initial terms up to 364 days and renewals up to 36 months. Final rules issued by the Departments of Labor, Health and Human Services and the Treasury in 2024 limited plans sold or issued on or after September 1, 2024, to an initial term of three months and a maximum of four months including renewals, and they also restricted stacking policies from the same insurer.

On August 7, 2025, the Department of Labor published a statement that the Departments do not intend to prioritize enforcement of the 2024 STLDI definition, including its notice requirement, until new rulemaking takes effect, and that HHS encourages states to take a similar approach. The Departments said they intend to propose amendments to the definition through notice-and-comment rulemaking. Because this area is in flux, check the Department of Labor's STLDI page and your state insurance department for the rules that apply when you buy.

Many people overlook Marketplace subsidies. Losing job-based coverage usually opens a special enrollment period, and income-based premium tax credits can make an ACA plan cheaper than expected. Our explainer on how health insurance subsidies work covers eligibility.

When is short-term coverage cost-effective?

It can make sense when

  • You are healthy, take no ongoing medications and expect a gap of a few weeks.
  • You missed Marketplace enrollment and do not qualify for a special enrollment period.
  • You do not qualify for subsidies and COBRA premiums are very high.

It is usually a poor fit when

  • You have any chronic condition, are pregnant or plan to become pregnant, or need regular prescriptions.
  • You qualify for Marketplace subsidies or Medicaid.
  • You are mid-treatment and need to keep your providers and deductible credit, which COBRA preserves.

A quick cost check

  1. Add the premiums for the full gap.
  2. Add the deductible and coinsurance you would pay for a plausible bad event, such as an emergency room visit.
  3. Read the exclusions and caps, and assume excluded care costs the full price.
  4. Compare the total with COBRA and a subsidized Marketplace plan for the same period.

Before buying any policy, review the fine print with the same care as other insurance purchases. Our list of things to watch when buying or renewing insurance applies here.

What employers and HR teams should know

Short-term plans often come up during offboarding and waiting periods. HR teams should send required COBRA notices, point departing employees to the Marketplace and avoid recommending specific short-term products. For new hires, a shorter benefits waiting period reduces the gap that drives people toward short-term coverage. Our open enrollment prep checklist covers benefit communications that help employees compare options.

Frequently Asked Questions

How long can a short-term health plan last?

Under the 2024 federal rule, new plans sold on or after September 1, 2024, were limited to three months initially and four months total. In 2025 federal agencies said they would not prioritize enforcing that limit while they revisit the rules, and states can set stricter limits. Check your state insurance department before buying.

Are short-term health plans available in every state?

No. According to healthinsurance.org, California, New Jersey and New York ban them, and several other states have rules or market conditions that leave no plans available. Availability can change as state and federal rules change, so confirm with your state insurance department or a licensed agent.

Does short-term insurance count as qualifying coverage?

No. Short-term plans are not minimum essential coverage under the ACA. When a short-term plan ends, that loss of coverage does not by itself qualify you for a Marketplace special enrollment period, so plan your exit to align with open enrollment or another qualifying event.

Next steps

  • Estimate how long your coverage gap will really last.
  • Check Marketplace subsidy eligibility and your COBRA election deadline.
  • If you consider a short-term plan, list its exclusions and caps in writing.
  • Confirm your state's current rules with the state insurance department.
