Losing health insurance — even temporarily — is one of the most financially precarious situations an American can face. A single emergency room visit averages $2,200, a three-day hospital stay runs roughly $30,000, and an unexpected surgery can generate bills exceeding $100,000. Short-term health insurance exists to bridge those dangerous gaps, offering temporary coverage at a fraction of the cost of a standard Affordable Care Act (ACA) plan. But that lower price comes with substantial tradeoffs that every buyer needs to understand before enrolling.
An estimated 2.8 million Americans currently hold short-term health insurance policies, a figure that has grown as healthcare costs have continued to climb. These plans appeal to people caught between coverage options — transitioning between employers, graduating from college, aging off a parent's plan at 26, or simply unable to afford the full cost of an ACA-compliant policy outside of subsidy eligibility. This guide breaks down how short-term health insurance actually works, what it will and will not pay for, where it is legal, and whether it is the right choice for your situation.
What Is Short-Term Health Insurance?
Short-term health insurance — also called short-term limited duration insurance (STLDI) — is a type of temporary medical coverage designed to protect against unexpected illnesses and injuries during a defined period. Unlike ACA-compliant plans sold on the health insurance marketplace, short-term plans are not required to follow the same consumer protections established by the Affordable Care Act.
The concept is straightforward: you pay a monthly premium, typically far less than an ACA plan, and receive coverage that pays for certain medical expenses if you get sick or injured. Policies generally include a deductible (often $2,500-$5,000), coinsurance (usually 20-50% after the deductible), and a benefit maximum (commonly $250,000 to $1 million per policy term).
What makes these plans "short-term" is their limited duration. Under current federal regulations established by a 2018 rule from the Department of Health and Human Services, short-term plans can last up to 364 days with total coverage through renewals extending up to 36 months. Before 2018, they were limited to three months with no renewals. Many states have since imposed their own stricter limits, creating a patchwork of rules that varies significantly depending on where you live.
The key distinction to understand from the outset: short-term plans are regulated more like property insurance than health insurance. Insurers can deny applications based on health history, exclude pre-existing conditions, set benefit caps, and cancel coverage under certain circumstances. These are all practices that ACA-compliant plans cannot do.
How Short-Term Plans Differ from ACA Coverage
The differences between short-term health insurance and an ACA marketplace plan are not minor — they represent fundamentally different approaches to health coverage. Understanding these differences is critical because many consumers purchase short-term plans expecting ACA-level protection at a discount, which is not what they receive.
| Feature | Short-Term Plan | ACA Marketplace Plan |
|---|---|---|
| Pre-existing conditions | Excluded from coverage | Must be covered; cannot charge more |
| Medical underwriting | Yes — can deny application based on health | No — guaranteed issue |
| Essential health benefits | Not required (often omits mental health, maternity, Rx) | All 10 required by law |
| Benefit maximums | $250K-$1M typical caps | No annual or lifetime limits |
| Premium subsidies | Not eligible for tax credits | Eligible based on income |
| Premium cost (30-year-old) | $110-$180/month | $350-$500/month (unsubsidized) |
| Enrollment period | Any time of year | Open enrollment or qualifying event |
| Maximum duration | Up to 364 days (federal); varies by state | 12-month plan year |
| Counts as minimum essential coverage | No | Yes |
| Preventive care | Usually not covered at no cost | Covered at no cost (in-network) |
The most consequential difference is the treatment of pre-existing conditions. If you have diabetes, take blood pressure medication, have been treated for anxiety or depression, or have virtually any ongoing health condition, a short-term plan will not cover treatment related to that condition. In some cases, the insurer may deny your application entirely. ACA plans, by contrast, must cover every applicant regardless of health status and cannot charge higher premiums based on medical history.
What Short-Term Plans Cover and Exclude
Short-term health insurance is designed primarily to protect against acute, unforeseen medical events — think broken bones, sudden infections, appendicitis, or car accident injuries. The coverage is built for otherwise healthy people who need a safety net against catastrophic costs, not for managing ongoing health needs.
What most short-term plans cover:
- Emergency room visits and urgent care
- Hospitalization for new conditions (subject to deductible and benefit cap)
- Surgery for non-pre-existing conditions
- Diagnostic testing (X-rays, MRIs, blood work) related to new conditions
- Some outpatient physician visits (often limited to a set number)
- Limited prescription drug coverage (varies widely by plan)
What most short-term plans exclude:
- Pre-existing conditions — Any condition diagnosed, treated, or symptomatic within the look-back period (typically 12-60 months). This is the single largest exclusion and the one most likely to result in denied claims.
- Mental health and substance use treatment — Approximately 85% of short-term plans do not cover therapy, psychiatry, or inpatient mental health services. Given that roughly one in five American adults experiences mental illness each year, this exclusion affects a significant portion of potential enrollees.
- Maternity and newborn care — Pregnancy and delivery are not covered by the vast majority of short-term plans. An uncomplicated delivery averages $13,000-$18,000; a cesarean section runs $22,000-$28,000. If pregnancy is a possibility, a short-term plan leaves you fully exposed.
- Preventive care and wellness visits — Annual physicals, cancer screenings, immunizations, and other preventive services are generally not covered or not covered at zero cost-sharing. Under ACA plans, all recommended preventive services must be free.
- Prescription drug coverage — About 40% of short-term plans offer no prescription coverage at all. Those that do often cap pharmacy benefits at $500-$1,500 per term or cover only generic medications.
- Chronic disease management — Even if a chronic condition develops during the coverage period, ongoing management after the plan term ends becomes a pre-existing condition for renewal purposes.
| Coverage Category | Short-Term Plans | ACA Bronze Plan | ACA Silver Plan |
|---|---|---|---|
| Doctor visits | Limited (3-6 per term typical) | Covered after deductible | Covered with copay |
| Emergency room | Covered after deductible | Covered after deductible | Covered with copay |
| Hospitalization | Covered up to benefit cap | Covered (no cap) | Covered (no cap) |
| Mental health | Usually excluded | Covered after deductible | Covered with copay |
| Maternity | Excluded | Covered after deductible | Covered after deductible |
| Prescription drugs | Limited or excluded | Covered after deductible | Covered with tiered copays |
| Preventive care | Not at zero cost | Free (in-network) | Free (in-network) |
| Rehabilitation | Limited or excluded | Covered | Covered |
Duration Limits: Federal Rules and State Variations
The duration rules for short-term health insurance have been a political tug-of-war for a decade. Under the Obama administration, short-term plans were limited to 90 days with no renewals. In 2018, the Trump administration extended the maximum to 364 days per term with total renewal periods of up to 36 months. The Biden administration proposed rolling back to 3-4 months but that rule was not finalized. As of 2026, the federal framework allows up to 364-day terms with renewals.
However, individual states retain the authority to impose stricter limits, and many have done exactly that. The result is a fragmented regulatory landscape where the same product is treated very differently depending on your zip code.
Federal maximum (default for states without their own rules): Initial term up to 364 days. Renewals permitted up to a total coverage duration of 36 months. Insurers may require new medical underwriting at each renewal.
States with stricter duration limits: Some states that allow short-term plans cap the initial term at 3, 6, or 11 months. Others limit total renewals to 12 months or prohibit renewals entirely. A handful of states allow the full federal maximum. Your agent or insurer should disclose the state-specific rules at application, but it pays to verify independently through your state department of insurance.
There is an important nuance around renewals. When a short-term plan renews, the insurer often treats it as a new application. Any condition that developed during the prior term — even something as common as a knee injury or a new prescription — may be classified as pre-existing on the renewal and excluded from coverage. This creates a paradox: the longer you stay on short-term insurance, the more likely you are to develop conditions that future renewals will not cover. For this reason, consumer advocates generally recommend treating short-term coverage as truly temporary rather than relying on it as a long-term solution.
Cost Comparison: Short-Term vs ACA Plans
The price difference between short-term and ACA coverage is the primary reason people choose short-term plans. On a pure premium-to-premium basis, short-term plans are dramatically cheaper. But a meaningful cost comparison requires looking beyond monthly premiums to consider out-of-pocket exposure, benefit limits, and subsidy eligibility.
| Cost Factor | Short-Term Plan | ACA Bronze | ACA Silver (with CSR) |
|---|---|---|---|
| Monthly premium (age 30) | $110-$180 | $350-$500 | $400-$560 |
| Monthly premium (age 45) | $160-$270 | $480-$670 | $530-$740 |
| Monthly premium (age 60) | $250-$420 | $900-$1,200 | $1,000-$1,350 |
| Typical deductible | $2,500-$5,000 | $7,000-$9,200 | $1,500-$3,500 |
| Benefit maximum | $250K-$1M | No limit | No limit |
| Annual premium cost (age 30) | $1,320-$2,160 | $4,200-$6,000 | $4,800-$6,720 |
| Max out-of-pocket (with serious illness) | $250K-$1M+ (plan cap) | $9,200 (2026 limit) | $3,000-$6,500 |
The table above reveals a critical distinction. Short-term plans have lower monthly premiums but offer no ceiling on your total financial exposure if something goes seriously wrong. An ACA plan with a $9,200 out-of-pocket maximum means that no matter how catastrophic your medical event, you will never pay more than that amount in a plan year. A short-term plan with a $500,000 benefit cap might sound generous until you learn that a complicated cancer treatment can exceed $1 million in the first year alone.
The subsidy factor also deserves close attention. Under the enhanced ACA premium subsidies — currently extended through 2025 and expected to be addressed by Congress for 2026 and beyond — households earning up to 400% of the federal poverty level ($58,320 for a single person in 2026) receive significant premium reductions. A 35-year-old earning $40,000 might pay just $180-$250 per month for a silver plan after subsidies, making the cost gap with short-term insurance much narrower or even nonexistent. If you have not checked your marketplace subsidy eligibility recently, it is worth doing before defaulting to a short-term plan.
Who Should Consider Short-Term Coverage
Short-term health insurance is not designed to be anyone's permanent solution. It occupies a specific niche: healthy individuals facing a defined, temporary gap in coverage who need protection against catastrophic costs. Here are the scenarios where it makes the most financial sense:
Between jobs (waiting for new employer benefits). Most employer health plans impose a waiting period of 30 to 90 days before new hires are eligible. If you are healthy, have no pre-existing conditions, and simply need a safety net for one to three months, a short-term plan can bridge that gap at a fraction of the cost of COBRA continuation coverage. A healthy 35-year-old might pay $450 total for three months of short-term coverage versus $1,800-$2,400 for COBRA.
Aging off a parent's plan at 26. Under the ACA, young adults can stay on a parent's health insurance until they turn 26. Turning 26 qualifies as a life event that triggers a Special Enrollment Period for marketplace plans, but if you miss that 60-day window, short-term insurance can cover you until the next Open Enrollment Period. Paying attention to monthly budgets during this transition is particularly important for recent graduates managing student loan payments alongside new insurance costs.
Missed the Open Enrollment Period. ACA marketplace enrollment runs from November 1 through January 15. If you miss that window and do not qualify for a Special Enrollment Period through a qualifying life event (job loss, marriage, birth of a child, relocation), your only options until the next enrollment period are short-term plans, COBRA, or health sharing ministries. In this scenario, short-term insurance is often the most affordable bridge.
Early retirees not yet eligible for Medicare. People who retire between ages 55 and 64 face some of the highest unsubsidized health insurance costs. A 62-year-old couple might face ACA premiums exceeding $2,000 per month before subsidies. If both are healthy and subsidy-ineligible (high retirement income), a short-term plan at $400-$600 per month for the couple could save $15,000-$20,000 annually, assuming they remain healthy. However, this is a higher-risk strategy given that health issues become more common with age.
Recent college graduates. Graduates who do not immediately start jobs with benefits may face a gap of several months. If they are healthy and under 26, staying on a parent's plan is almost always the better option. But if parental coverage is not available, a short-term plan provides basic protection during the job search at a cost that fits a tight budget.
State Restrictions and Bans
Not every state allows short-term health insurance. As of 2026, eleven states and the District of Columbia either ban these plans outright or restrict them so severely that they are effectively unavailable. These states generally have robust ACA marketplace participation and view short-term plans as a threat to the stability of their individual insurance markets, since short-term plans siphon healthy enrollees away from the ACA risk pool, potentially raising premiums for everyone else.
| State | Status | Maximum Duration Allowed |
|---|---|---|
| California | Banned | N/A |
| Colorado | Severely restricted | 6 months, no renewals |
| Connecticut | Severely restricted | 6 months, no renewals |
| Hawaii | Severely restricted | 6 months, limited renewals |
| Maine | Severely restricted | 6 months, no renewals |
| Massachusetts | Banned | N/A |
| New Jersey | Banned | N/A |
| New York | Banned | N/A |
| Rhode Island | Severely restricted | 3 months, no renewals |
| Vermont | Banned | N/A |
| Washington | Severely restricted | 3 months, no renewals |
| District of Columbia | Banned | N/A |
In states that allow short-term plans under the full federal framework, the maximum initial term is 364 days with renewals up to 36 months total. Several other states fall between these extremes, allowing short-term plans but imposing duration caps shorter than the federal maximum — typically 6 or 11 months with limited or no renewal options.
If you live in a state that bans or heavily restricts short-term insurance, your best alternatives are ACA marketplace plans (with potential subsidies), COBRA continuation from a previous employer, Medicaid (if income-eligible), or health sharing ministries. Our guide to the best health insurance companies covers the major ACA carriers and how to choose between them.
How to Apply for Short-Term Health Insurance
One of the practical advantages of short-term health insurance is that you can apply and receive coverage quickly — often within 24 to 48 hours — at any time of year. There is no enrollment window to wait for. Here is how the application process typically works:
Step 1: Gather your health history. Unlike ACA plans, short-term insurers ask detailed health questions. You will need to disclose current medications, past diagnoses, recent surgeries, ongoing treatments, and sometimes family medical history. Be completely honest — misrepresenting your health history is grounds for policy rescission, which means the insurer can retroactively cancel your coverage and deny all claims.
Step 2: Compare plans from multiple carriers. Use an aggregator site (eHealth, HealthMarkets, or GoHealth) or work with a licensed insurance broker. Compare not just monthly premiums but deductibles, coinsurance percentages, benefit maximums, covered services, and provider networks. The cheapest plan by premium may have a $10,000 deductible and a $250,000 cap — while a slightly more expensive plan might offer a $2,500 deductible and a $1 million cap.
Step 3: Complete the application. Applications are typically online and take 15-30 minutes. The health questionnaire is the most critical section. Based on your answers, the insurer will either approve your application, approve with specific condition exclusions, or deny you outright. Denial rates for short-term plans vary by insurer but generally range from 10% to 25% of applicants.
Step 4: Choose your start date. Most short-term plans allow you to select a coverage start date within the next 1 to 30 days. Some offer next-day effective dates for an additional fee. Coordinate your start date with the end of any existing coverage to avoid a gap.
Step 5: Understand what happens at renewal. If your plan term expires and you want to continue coverage, you will likely need to reapply. Any conditions that arose during the prior term may be excluded. Review the renewal terms in your policy before you need them — do not wait until the last week of your term to find out how renewal works.
A useful benchmark for budgeting: if you are healthy and have a clean medical history, expect to set aside an additional $5,000-$10,000 in liquid savings as a self-insurance buffer. This covers the deductible on your short-term plan plus out-of-pocket costs for services the plan does not cover. Having an adequate emergency fund is especially important when relying on coverage with benefit limitations. If you are also investing for the future, coordinating a health savings account (HSA) strategy can provide tax-advantaged medical savings — though note that HSAs are only available with HSA-eligible high-deductible plans, and most short-term plans do not qualify.
Alternatives to Short-Term Health Insurance
Before committing to a short-term plan, evaluate these alternatives that may provide better coverage, more consumer protections, or comparable costs:
COBRA continuation coverage. If you recently left a job that provided health insurance, the Consolidated Omnibus Budget Reconciliation Act (COBRA) allows you to continue your employer's group plan for up to 18 months (36 months in some circumstances). The catch: you pay the full premium plus a 2% administrative fee, which typically runs $600-$700 per month for individual coverage or $1,700-$2,000 for family coverage. COBRA is expensive, but it maintains your exact same coverage with no pre-existing condition exclusions and counts as minimum essential coverage. It is often the best option for people with ongoing health conditions.
ACA marketplace Special Enrollment Period (SEP). Qualifying life events — including job loss, moving to a new state, getting married, having a baby, or losing other health coverage — trigger a 60-day Special Enrollment Period to buy an ACA plan outside of Open Enrollment. Many people who think they are stuck without options actually qualify for an SEP. Check HealthCare.gov or your state's exchange to see if a recent life event makes you eligible.
Medicaid. If your income has dropped (due to job loss, for example), you may qualify for Medicaid, which provides comprehensive coverage at little to no cost. Income limits vary by state, but in the 40 states plus DC that expanded Medicaid, adults earning up to 138% of the federal poverty level ($20,783 for a single person in 2026) are eligible. Medicaid applications are accepted year-round with no enrollment window.
Health sharing ministries. These are faith-based organizations where members contribute monthly "shares" that are used to pay each other's medical bills. Monthly costs range from $150-$500 depending on age and plan level. Health sharing ministries are not insurance — they are not regulated by state insurance departments, and there is no legal guarantee that your bills will be paid. However, they do provide an alternative for people who cannot afford ACA coverage and are ineligible for subsidies or Medicaid.
Spouse or domestic partner's employer plan. If your spouse or domestic partner has employer-sponsored insurance, you may be able to join their plan. Most employers allow enrollment within 30 days of a qualifying life event such as losing your own coverage. Employer plans are typically the most cost-effective option because the employer subsidizes a portion of the premium.

Frequently Asked Questions About Short-Term Health Insurance
No. Short-term health insurance plans almost universally exclude pre-existing conditions. Any medical condition for which you received treatment, diagnosis, or advice in the 12 to 60 months before applying will not be covered. This includes chronic conditions like diabetes, asthma, heart disease, and depression. Some plans also apply a look-back period during underwriting and may deny your application entirely based on your health history.
Under federal rules, short-term plans can last up to 364 days with renewals extending total coverage up to 36 months. However, many states impose stricter limits — some cap initial terms at 3 or 6 months, and several states ban short-term plans entirely. When renewing, the insurer may require a new application and any conditions developed during the previous term could be excluded as pre-existing.
Yes, short-term plans typically cost 50-80% less than comparable ACA marketplace plans on a premium basis. A 30-year-old might pay $110-$180 per month versus $350-$500 for an unsubsidized ACA bronze plan. However, short-term plans are cheaper because they cover far less. If you qualify for ACA premium tax credits, a marketplace plan may actually cost less than a short-term plan while providing comprehensive coverage.
As of 2026, states with outright bans include California, Massachusetts, New Jersey, New York, and Vermont. States with severe restrictions include Colorado, Connecticut, Hawaii, Maine, Rhode Island, and Washington. The District of Columbia also bans short-term plans. These eleven jurisdictions generally have strong ACA marketplace participation.
No. While the federal individual mandate penalty was reduced to $0 in 2019, several states including California, Massachusetts, New Jersey, Rhode Island, and the District of Columbia still impose their own penalties for being uninsured. If you live in one of those states, relying solely on a short-term plan may result in a state tax penalty. Short-term coverage also does not qualify you for a Special Enrollment Period.
If you develop a serious illness while covered, the plan will generally cover initial treatment up to its benefit caps, provided the condition was not pre-existing. However, many plans impose benefit maximums of $250,000 to $1 million — potentially insufficient for serious conditions like cancer. When the plan term ends, your new condition becomes pre-existing for renewal purposes and may be excluded. You may then need to wait for ACA Open Enrollment unless you qualify for a Special Enrollment Period.
The Essentials
- Short-term health insurance costs 50-80% less than ACA plans ($110-$180/month vs $350-$500 for a 30-year-old), but that savings comes from excluding pre-existing conditions, mental health, maternity care, and imposing benefit caps.
- Federal rules allow plans up to 364 days with renewals to 36 months, but 11 states plus DC ban or severely restrict short-term coverage. Check your state's rules before shopping.
- Short-term plans work best for healthy individuals facing a defined, temporary gap — between jobs, aging off a parent's plan, or waiting for employer benefits. They are not designed as long-term coverage.
- Always check ACA marketplace subsidy eligibility before buying a short-term plan. With premium tax credits, an ACA silver plan may cost the same or less while covering far more.
- If you have any pre-existing conditions, short-term insurance will not cover treatment for those conditions. COBRA, marketplace SEPs, or Medicaid are almost always better options in that situation.
- Keep at least $5,000-$10,000 in liquid savings as a buffer when relying on short-term coverage. The combination of deductibles, coinsurance, benefit caps, and coverage gaps means your out-of-pocket exposure can be substantial.
