Quick Answer
Short term health insurance offers coverage lasting 1 to 364 days per federal rules, with monthly premiums averaging $124–$199 for a healthy 30-year-old as of July 2025. It fills gaps cheaply but excludes pre-existing conditions and ACA essential health benefits — making it a calculated risk, not a safety net.
Short term health insurance is a limited-duration medical plan designed to bridge coverage gaps — not replace comprehensive insurance. According to KFF’s analysis of short-term plan enrollment, these plans can legally exclude pre-existing conditions, cap annual benefits, and deny claims for conditions that ACA-compliant plans must cover.
With ACA marketplace premiums rising and coverage gaps widening for gig workers and job-switchers, short term health insurance has surged in demand — but the tradeoffs are significant and often misunderstood.
What Does Short Term Health Insurance Actually Cover?
Short term health insurance covers basic acute care — doctor visits, emergency room trips, and hospitalizations — but it does NOT cover the ten essential health benefits mandated by the Affordable Care Act (ACA). That means no guaranteed coverage for mental health, maternity care, prescription drugs, or preventive services.
Insurers like UnitedHealthcare, Pivot Health, and National General offer short-term plans with varying benefit tiers. Most include a deductible ranging from $1,000 to $10,000, a coinsurance structure, and a hard benefit cap — often between $250,000 and $2 million per term.
What Is Typically Excluded?
Exclusions are where short-term plans expose their biggest gaps. Common exclusions include:
- Pre-existing conditions (any diagnosis or treatment in the prior 2–5 years)
- Prescription drug coverage (unless added as a rider)
- Maternity and newborn care
- Mental health and substance use disorder treatment
- Preventive care and wellness visits
The Centers for Medicare and Medicaid Services (CMS) defines short-term plans as lasting fewer than 12 months with a maximum renewal period of 36 months under current federal rules. State rules vary sharply — states like California, New York, and New Jersey ban short-term plans entirely.
Key Takeaway: Short term health insurance covers acute care but excludes ACA-mandated benefits. Per CMS guidelines, plans can last up to 364 days and renew for up to 36 months — but pre-existing conditions and mental health care are routinely excluded.
How Much Does Short Term Health Insurance Cost?
Short term health insurance costs significantly less than ACA marketplace plans upfront, but the out-of-pocket exposure can be far higher if you get sick. A healthy 30-year-old pays roughly $124–$199 per month, compared to an average ACA benchmark premium of $477 per month before subsidies in 2024, according to KFF’s 2024 premium data.
Premium cost depends on age, health status, state, deductible level, and benefit cap. Unlike ACA plans, short-term insurers use medical underwriting — meaning they can charge more or deny coverage based on your health history.
| Plan Type | Avg. Monthly Premium (Age 30) | Pre-Existing Conditions Covered? | Benefit Cap |
|---|---|---|---|
| Short-Term Plan | $124–$199 | No | $250,000–$2M per term |
| ACA Bronze Plan | $350–$450 | Yes | No annual/lifetime cap |
| ACA Silver Plan | $450–$550 | Yes | No annual/lifetime cap |
| COBRA Continuation | $600–$700+ | Yes | No annual/lifetime cap |

Understanding the full cost picture — including deductibles — is critical; our breakdown of common health insurance deductible mistakes explains why low premiums can become expensive traps.
Key Takeaway: Short term health insurance premiums average $124–$199/month for a 30-year-old — roughly 60–70% cheaper than ACA Silver plans before subsidies. But high deductibles and benefit caps mean a single serious illness can cost tens of thousands more out-of-pocket. See KFF’s short-term plan analysis for full cost modeling.
Who Should — and Should Not — Consider Short Term Health Insurance?
Short term health insurance is best suited for healthy individuals facing a defined, short coverage gap — not as a long-term solution. Ideal candidates are people between jobs, recent college graduates aging off a parent’s plan, early retirees not yet eligible for Medicare, or those who missed ACA Open Enrollment and don’t qualify for a Special Enrollment Period.
It is a poor fit for anyone with chronic conditions, a history of serious illness, pregnancy plans, or regular prescription needs. The Department of Health and Human Services (HHS) has repeatedly warned consumers that these plans leave people exposed to catastrophic costs when major health events occur.
The Gig Worker Dilemma
Freelancers and gig economy workers represent one of the fastest-growing short-term plan demographics. Without employer-sponsored coverage, the temptation of a $150/month premium is real. Our comprehensive resource on building an insurance safety net as a freelancer outlines why short-term plans should be a last resort, not a default choice.
“Short-term plans can look like a bargain until you actually need care. A cancer diagnosis, a car accident, a premature birth — any of these can trigger benefit limits or exclusions that leave patients with hundreds of thousands of dollars in uncovered bills.”
Key Takeaway: Short term health insurance suits healthy people with coverage gaps under 12 months. Anyone with pre-existing conditions, pregnancy plans, or chronic illness faces serious financial exposure. HHS recommends ACA marketplace coverage as the primary alternative for anyone who qualifies for subsidies.
What Are the Legal and Regulatory Risks of Short Term Health Insurance?
Short term health insurance exists in a shifting regulatory environment. In 2024, the Biden administration finalized a rule limiting short-term plans to 3 months with a maximum renewal of 4 months — a rollback from the Trump-era 364-day rule. However, federal courts blocked that rule in several states, creating a patchwork of coverage durations depending on where you live.
As of mid-2025, more than 15 states have enacted their own restrictions or outright bans on short-term plans. States including California, Massachusetts, New York, and Washington prohibit them entirely. States like Texas and Florida allow the full federal maximum. Checking your state’s Department of Insurance website is essential before purchasing.
Consumers have also filed complaints against insurers for retroactive claim denials — a practice where an insurer investigates your medical history after a large claim and rescinds coverage based on an alleged pre-existing condition. The National Association of Insurance Commissioners (NAIC) tracks these complaints through its Consumer Insurance Information database.
If you’ve recently experienced a life change — job loss, divorce, relocation — you may qualify for a Special Enrollment Period and access ACA coverage instead. Our guide on health insurance options after job loss explains exactly when that window opens and how to use it. For those tracking the latest marketplace changes, see what’s new in health insurance open enrollment for 2026.
Key Takeaway: Federal rules on short term health insurance have changed multiple times since 2018, and over 15 states now restrict or ban these plans. Retroactive claim denials remain a documented risk. Always verify current rules with your state’s NAIC-affiliated Department of Insurance before enrolling.
What Are the Best Alternatives to Short Term Health Insurance?
Before defaulting to short term health insurance, evaluate whether a better-protected option is available. Several alternatives offer broader coverage at competitive costs, especially for those who qualify for ACA subsidies.
- ACA Marketplace Plans: Available year-round during Special Enrollment Periods. Subsidies through the Advance Premium Tax Credit (APTC) can reduce costs to near zero for lower-income households.
- Medicaid: Free or very low-cost coverage for those earning under 138% of the federal poverty level in expansion states.
- COBRA: Continues your employer plan for up to 18 months after job loss, though full premiums average $600–$700/month.
- Health Sharing Ministries: Not insurance, but a lower-cost option for some; no regulatory consumer protections apply.
- Catastrophic Plans: ACA-compliant low-premium plans available to adults under 30 or those with hardship exemptions.
Understanding how your insurance needs shift with life events is critical. Our overview of updating insurance after a major life event covers exactly when each alternative becomes available and how to switch without a gap in coverage.
Key Takeaway: ACA marketplace plans with subsidies often cost less than short term health insurance for income-eligible enrollees. COBRA preserves full benefits for up to 18 months. Before buying a short-term plan, use the HealthCare.gov subsidy estimator to check if you qualify for reduced ACA premiums.
Frequently Asked Questions
Is short term health insurance ACA compliant?
No. Short term health insurance is explicitly exempt from ACA requirements. It does not have to cover the ten essential health benefits, cannot be community-rated, and can deny coverage for pre-existing conditions. Enrolling in a short-term plan does not satisfy any ACA mandate.
Can short term health insurance deny claims after I enroll?
Yes, and it happens. Insurers can conduct post-claim underwriting — reviewing your medical history after a large claim to determine if a pre-existing condition existed. If they find one, they can rescind coverage retroactively. This practice is documented in complaints filed with the NAIC and state Departments of Insurance.
How long can I keep short term health insurance?
Under current federal rules, a single short-term plan can last up to 364 days and be renewed for a total duration of up to 36 months. However, many states set shorter limits or ban renewals entirely. Check your state’s rules before assuming you can extend coverage.
Does short term health insurance cover pre-existing conditions?
No. This is the most critical distinction from ACA plans. Short term health insurance can legally exclude any condition diagnosed or treated before coverage began, often going back 2 to 5 years. Anyone with a medical history should treat this exclusion as a near-certainty, not a possibility.
What happens if I get seriously ill on a short-term plan?
If a serious illness falls within the plan’s covered conditions and benefit cap, you will receive partial coverage. But if the illness is deemed a pre-existing condition, or if your bills exceed the benefit cap, you bear all remaining costs. A single hospitalization averaging $15,000–$30,000 can exhaust many short-term plan limits quickly.
Is short term health insurance worth it for a healthy 25-year-old between jobs?
Potentially, for a narrow window. If you are healthy, have no prescriptions, expect no planned procedures, and your gap is under three months, a short-term plan offers a cost-effective stopgap. But first check if you qualify for an ACA Special Enrollment Period or Medicaid — either may offer better protection at a comparable or lower cost.
