What short-term health insurance is and when people use it

Short-term health insurance is a temporary plan that covers medical expenses for a set period — usually between 3 and 12 months, depending on your state and the insurer. It is not the same as major medical insurance (the kind you get through an employer or the health marketplace). Short-term plans have lower monthly premiums but cover fewer things and have higher out-of-pocket costs when you do use them.

People typically buy short-term coverage during gaps in their regular insurance — between jobs, while waiting for employer coverage to start, during a divorce, or after aging off a parent's plan. Some use it as a temporary bridge while they decide on a longer-term plan. Short-term plans are sold directly by insurers, not through the government marketplace.

The trade-off is straightforward: you pay less per month, but the plan covers less, and you are responsible for more of the bill when you need care. Pre-existing conditions are usually not covered, and routine preventive care may not be included.

Key Takeaways

  • Short-term plans cost less per month than major medical insurance but cover fewer services and require you to pay more out of pocket when you use them.
  • Coverage periods last 3 to 12 months depending on your state, and you cannot renew indefinitely — most states limit total coverage to 3 to 6 months per year.
  • Pre-existing conditions are typically excluded, and routine preventive care, mental health services, and prescription drugs may not be covered or may have separate high deductibles.
  • Short-term plans do not count as coverage under federal law, so you may owe a penalty on your taxes if you have no other insurance for part of the year.
  • You buy short-term plans directly from insurers like Cigna, Aetna, or regional carriers — not through the health marketplace or your employer.

What short-term plans actually cover

Coverage varies by plan and insurer, but short-term policies typically cover emergency room visits, hospital stays, and urgent care. Many include some outpatient services like X-rays and lab work. However, they almost never cover routine doctor visits, preventive screenings, mental health treatment, or prescription drugs — or if they do, you pay a separate high deductible for each category.

Pre-existing conditions are excluded by design. If you have diabetes, asthma, high blood pressure, or any condition diagnosed before your coverage starts, claims related to that condition will be denied. Some plans have a waiting period (often 30 days) before any coverage kicks in at all.

Maternity care, dental, vision, and physical therapy are almost never included. If you need any of these, you pay the full cost out of pocket. This is why short-term insurance is meant to be a safety net for major medical events, not a replacement for comprehensive coverage.

How much short-term plans cost and what you pay when you use them

Monthly premiums for short-term plans are typically 40 to 60 percent lower than comparable major medical plans — sometimes $50 to $150 per month for an individual, though this varies widely by age, location, and the insurer. The catch is the deductible and out-of-pocket maximum.

Most short-term plans have deductibles between $1,000 and $5,000 per person, meaning you pay that amount out of pocket before the plan pays anything. Once you hit the deductible, the plan usually covers 60 to 80 percent of the next costs, and you pay the rest. The out-of-pocket maximum — the most you will pay in a year — is often $10,000 to $25,000 or higher.

A hospital stay or emergency surgery can quickly exceed what the plan covers. If you have a serious accident or illness, you could end up owing thousands of dollars even with the plan in place. This is why short-term coverage is not a substitute for major medical insurance if you have any health risks or ongoing medical needs.

How long coverage lasts and renewal rules

Short-term plans are sold for initial periods of 3 to 12 months, depending on your state. Some states allow longer initial periods; others cap them at 3 or 6 months. When your initial period ends, you can renew for another term, but federal rules limit how much total short-term coverage you can have in a 12-month period.

As of 2024, federal regulations allow short-term plans to cover no more than 3 months initially, with renewals allowed up to a total of 4 months in a 12-month period. However, some states have stricter rules — a few states do not allow short-term plans at all, and others cap total coverage at 6 months per year. Check your state's insurance department website to see what applies where you live.

You cannot use short-term plans indefinitely as a substitute for regular insurance. If you need coverage beyond the state limit, you will need to move to a major medical plan or another type of coverage.

Tax penalties and how short-term plans affect your taxes

Short-term health insurance does not count as "minimum essential coverage" under federal tax law. This means that if you have no other insurance for any month of the year, you may owe a penalty when you file your taxes — though the federal penalty itself is currently $0. However, some states impose their own penalties for being uninsured, and that amount varies.

More importantly, if you are receiving a tax credit to help pay for marketplace insurance, being on a short-term plan instead will disqualify you from that credit. If you are considering short-term coverage, check whether you would lose any subsidies you currently receive.

When you file your taxes, you will need to report any months you had short-term coverage separately from months you had major medical insurance. Keep your plan documents and any paperwork showing your coverage dates.

When short-term insurance makes sense and when it does not

Short-term coverage works best in specific situations: you are between jobs and your new employer's coverage does not start for two months; you are aging off your parents' plan and need a bridge until you turn 26 and can go back on; you are waiting for marketplace open enrollment; or you have a planned gap in coverage and want protection against a major accident or emergency.

Short-term insurance does not make sense if you have any ongoing medical needs, take prescription medications regularly, see a doctor more than once or twice a year, or have a pre-existing condition. It also does not make sense if you are trying to avoid marketplace coverage because you think it is too expensive — in that case, you may be may be able to access for a tax credit that would make a major medical plan cheaper than you think.

If you are young and healthy and truly only need coverage for a few months, short-term insurance can save you money. If you have any uncertainty about your health needs or how long you will need coverage, a major medical plan or marketplace plan with a tax credit is usually the safer choice.

How to compare short-term plans and what to read before you buy

Short-term plans are sold directly by insurers — companies like Cigna, Aetna, United Healthcare, and regional carriers. You can visit their websites, call their sales lines, or use a broker who sells multiple plans. There is no single marketplace where you can compare all short-term plans side by side the way you can with marketplace plans.

Before you buy, read the plan's summary of coverage document (sometimes called a "benefits summary" or "coverage outline"). This document lists exactly what is and is not covered, the deductible, the out-of-pocket maximum, and any exclusions or waiting periods. Pay special attention to the pre-existing condition clause — it will tell you whether any of your current health conditions are excluded.

Ask the insurer directly: What is not covered? What is the deductible for emergency room visits versus hospital stays? Is there a waiting period? Can I renew after my initial period ends, and for how long? What happens if I need care for a condition I had before the plan started? Write down the answers and keep them with your plan documents.

Frequently Asked Questions

Can I use short-term insurance if I have a pre-existing condition?

No. Short-term plans exclude pre-existing conditions by law. If you have been diagnosed with any condition before your coverage starts, claims related to that condition will be denied. If you have an ongoing health condition, you need a major medical plan, which cannot exclude pre-existing conditions.

What happens if I get sick or injured while on a short-term plan?

The plan will cover some costs if the condition is not pre-existing and is covered under the plan. However, you will pay your deductible first (usually $1,000 to $5,000), then the plan covers 60 to 80 percent of the rest. You are responsible for the remaining 20 to 40 percent, up to your out-of-pocket maximum. A serious illness or injury can cost you thousands even with the plan.

Can I switch from short-term insurance to a marketplace plan?

Yes, but only during open enrollment (usually November through January) or if you have a may have access to life event like losing your job or moving to a new state. You cannot switch to a marketplace plan in the middle of the year just because you want to. If your short-term coverage ends before open enrollment, you may have a gap in coverage.

Do short-term plans cover prescription drugs?

Most short-term plans do not cover prescription drugs, or they cover them only with a separate high deductible. If you take medications regularly, you will pay the full cost out of pocket. This is one of the biggest gaps in short-term coverage and a reason it does not work for people with ongoing medical needs.

What is the difference between short-term insurance and a health sharing ministry?

Short-term insurance is actual insurance sold by licensed insurers and regulated by state insurance departments. Health sharing ministries are membership organizations that pool money to pay members' medical bills, but they are not insurance and are not required to cover anything. Short-term plans have legal obligations to pay covered claims; ministries do not. If cost is your concern, compare short-term plans to marketplace plans with tax credits before considering a ministry.
