Short-Term Health Insurance: What It Covers, What It Doesn’t, and When It Makes Sense

By Paul Z Olah  |  July 18, 2026

Short-term health insurance occupies a unique and often misunderstood corner of the health coverage landscape. For some people, it’s a practical, affordable solution for a temporary coverage gap. For others, it’s a costly trap that leaves them underinsured precisely when they need coverage most. Understanding which situation you’re in requires knowing exactly what short-term plans cover, what they exclude, and when they make sense as a legitimate coverage option.

According to the Kaiser Family Foundation, approximately 3 million Americans purchase short-term health plans in any given year. The number fluctuates with regulatory changes, marketplace premium levels, and economic conditions. But regardless of volume, the product itself remains the same: a non-ACA-compliant insurance product that trades comprehensiveness for lower premiums and flexibility.

What Short-Term Health Insurance Actually Is

Short-term health insurance — formally called “short-term, limited-duration insurance” or STLDI — is a category of health coverage explicitly exempt from the Affordable Care Act’s consumer protection requirements. That exemption is both what makes it cheaper than ACA-compliant plans and what makes it potentially dangerous for people who don’t understand what they’re buying.

Traditionally, short-term plans were designed for gaps of a few months — hence the name. Federal rules were tightened in 2018 to allow plans lasting up to 364 days with renewals up to 36 months total, then restricted again in 2024 by the Biden administration to initial terms of no more than 3 months with total coverage of no more than 4 months. As of 2025, the regulatory status of short-term plan duration limits continues to evolve — check current federal rules or consult a broker for the most up-to-date guidance.

In New Jersey, state law takes a stricter approach. NJ does not permit short-term health plans to be sold to NJ residents at all. Garden State Benefits’ clients in New Jersey who need temporary coverage must use other options — continuation coverage, marketplace SEP plans, or Medicaid if eligible. Residents of other states where short-term plans are permitted have more flexibility.

What Short-Term Plans Cover

Short-term plans vary significantly by carrier and state, but most cover basic hospitalization, emergency care, surgery, and some outpatient physician services. The specific coverage is defined in the plan’s certificate of coverage — a document that is often long, complex, and full of exclusions that aren’t visible in the marketing materials.

Some short-term plans offer optional add-ons or riders for prescription drugs, preventive care, or accident coverage. Without these riders, short-term plans typically offer little or no prescription drug coverage — a critical gap for anyone taking regular medications.

Benefit limits are common in short-term plans. A plan may cap hospital benefits at $1 million or impose per-day limits on hospital stays ($500/day, for example). For a serious illness or injury that generates $500,000 in medical bills, a short-term plan might cover a fraction of those costs — leaving the individual with substantial uninsured debt.

What Short-Term Plans Exclude

The exclusions in short-term health plans are where the real risk lives. Because these plans are not subject to ACA requirements, they can and typically do exclude:

  • Pre-existing conditions: Most short-term plans exclude coverage for any condition for which you received diagnosis or treatment in the preceding 2 to 5 years. A person with diabetes, asthma, a history of cancer, or even a recently treated sinus infection may find their condition excluded.
  • Mental health and substance use disorders: ACA plans are required to cover these at parity with medical benefits. Short-term plans are not and often exclude them entirely.
  • Maternity care: Prenatal care, labor, delivery, and postpartum care are frequently excluded from short-term plans. An unexpected pregnancy on a short-term plan can result in tens of thousands of dollars in uninsured costs.
  • Prescription drugs: Without a rider, prescription coverage is often absent or severely limited.
  • Preventive care: Annual physicals, cancer screenings, and vaccinations — covered at no cost on ACA plans — may not be covered on short-term plans.

The pre-existing condition exclusion is the most consequential for most people. Unlike ACA plans, short-term insurers can — and routinely do — deny claims after the fact by conducting post-claim underwriting: reviewing your medical records after a claim is submitted to determine whether the condition was pre-existing. A 2020 report from the House Energy and Commerce Committee found that short-term plan insurers denied between 12% and 54% of claims in various states.

When Short-Term Health Insurance Makes Sense

Despite these limitations, there are genuinely appropriate use cases for short-term health insurance. The common thread is: a healthy individual who needs temporary coverage for a defined, short period and who understands precisely what they’re not covered for.

Young adults in a job transition: A 26-year-old who just graduated, aged off a parent’s plan, and is starting a job with a 60-day waiting period before benefits begin — and who has no pre-existing conditions and takes no regular medications — may find a short-term plan a reasonable bridge for that 60 days.

Early retirees waiting for Medicare: Someone who retires at 63 and needs coverage until Medicare eligibility at 65 has limited options. If their income is too high for marketplace subsidies to make marketplace plans affordable, a short-term plan might be the most cost-effective bridge — provided they understand the exclusion risks.

Coverage during a temporary international assignment: Employees sent abroad for a short period may find short-term international health plans more appropriate than maintaining domestic coverage. This is a specialized use case that requires careful evaluation.

In all of these scenarios, the key qualifier is: the person is healthy, understands the exclusions, and has a defined end date for when they’ll transition to comprehensive coverage. If any of those conditions aren’t met, the risk of being underinsured at a critical moment is too high.

Short-Term Plans vs. ACA Marketplace Plans: The Real Cost Comparison

The premium comparison between short-term and ACA plans often favors short-term plans significantly — a short-term plan for a healthy 35-year-old might cost $150/month versus $400/month for a comparable ACA silver plan. But this comparison is misleading without accounting for the value of what you’re giving up.

ACA marketplace plans include premium tax credits for individuals earning between 100% and 400% of the federal poverty level (and above that threshold through 2025 under the enhanced subsidy rules). Many people who would benefit from ACA coverage don’t investigate the subsidies they qualify for and default to short-term plans based on sticker price comparisons. When subsidies are factored in, ACA plans are often cost-competitive with or cheaper than short-term plans for people at many income levels.

Additionally, the out-of-pocket maximum on ACA plans ($9,450 for individuals in 2024) caps your total annual exposure. Short-term plans may have no out-of-pocket maximum — meaning a catastrophic illness could leave you with unlimited personal liability for uninsured costs.

Regulatory Changes and What They Mean for Consumers

The regulatory environment for short-term plans has changed multiple times in recent years and continues to evolve. Rules enacted in 2018 expanded duration; rules enacted in 2024 restricted it. State rules vary dramatically — some states ban short-term plans outright (NJ, NY, MA, WA, among others), others have few restrictions.

This volatility makes it essential to verify the current rules in your state before purchasing a short-term plan. A licensed broker who is current on regulatory developments — rather than a website that generates leads for whatever carrier pays the highest commission — is your most reliable source of guidance.

Frequently Asked Questions

Can I buy a short-term plan in New Jersey?

No. New Jersey does not permit short-term health plans to be sold to NJ residents. If you need temporary coverage in NJ, your options are continuation coverage (COBRA or NJ Mini-COBRA), a marketplace Special Enrollment Period plan (if you have a qualifying event), or Medicaid if you meet income requirements. A licensed broker can help you evaluate all three.

Will a short-term plan cover me if I get COVID-19 or another infectious disease?

It depends on the plan. Some short-term plans cover infectious disease treatment, others exclude it or have specific limitations. Review the certificate of coverage carefully before purchasing. Note that post-COVID conditions (long COVID) may be treated as a pre-existing condition on a subsequent short-term plan if you seek treatment during a prior plan period.

Can a short-term plan deny my claim after I’ve already paid premiums for months?

Yes. Post-claim underwriting — reviewing your medical history after a claim is submitted — is a common practice among short-term plan insurers. If the insurer determines that a condition was pre-existing, it can deny the claim even if you paid premiums for months without issue. This is one of the most significant consumer protection risks with short-term plans.

Is short-term health insurance the same as catastrophic coverage?

No. ACA catastrophic plans are ACA-compliant plans designed for people under 30 or those with hardship exemptions. They cover ACA essential health benefits and have the same consumer protections as other ACA plans. Short-term plans are a different, non-ACA category with far fewer protections. The two products are sometimes confused because both have lower premiums, but they are fundamentally different.

What should I do if I’m stuck in a short-term plan and become seriously ill?

If you experience a qualifying life event while on a short-term plan (the short-term plan itself ending is a qualifying event in some states), you may be able to enroll in an ACA plan through a Special Enrollment Period. Consult a licensed broker immediately — time is critical. If you’re in New Jersey, you have additional state-level protections worth exploring with a broker who knows NJ law.
