However, these plans come with critical trade-offs: they exclude pre-existing conditions, cap benefits at $500,000–$2 million, and do not cover essential health benefits like maternity care, mental health services, or prescription drugs. Since 2019, the federal maximum coverage period is 364 days (renewable up to 36 months in some states), but 14 states ban them entirely. For healthy individuals between jobs or waiting for ACA enrollment, short-term plans can save 40–60% on premiums, but they carry significant financial risk if you develop a serious illness. This guide breaks down every pro, con, and hidden rule so you can make an informed choice.

What Is Short-Term Health Insurance and How Does It Work?

Short-term health insurance, also called "short-term limited duration insurance" (STLDI), is a type of health coverage designed to fill temporary gaps in insurance. According to the National Association of Insurance Commissioners (NAIC), these plans were originally intended for 90-day coverage periods, but Trump-era rule changes in 2018 extended the maximum initial term to 364 days, with renewals allowed up to 36 months in most states.

Here's how they work:

• Monthly premiums: $120–$350 for a 40-year-old non-smoker, versus $456–$600+ for an ACA bronze plan.
• Deductibles: Typically $2,500–$10,000, with some plans offering $0 deductible options.
• Maximum benefits: $500,000 to $2 million per policy period, with some carriers like Pivot Health offering up to $5 million.
• No network restrictions: Many plans allow you to see any doctor or hospital, but out-of-network care may be reimbursed at 50–70% of allowed amounts.
• No medical underwriting: You answer health questions, and carriers can deny coverage for pre-existing conditions. The Health Insurance Portability and Accountability Act (HIPAA) does not apply to STLDI plans.

Key regulatory note: As of 2025, 14 states (including California, New York, Massachusetts, and New Jersey) ban short-term plans entirely. 8 states restrict coverage to 3–6 months. Check your state's insurance department website before applying.

What Are the Pros of Short-Term Health Insurance?

1. Lower Premiums Save You 40–60% Monthly

The primary advantage is cost. According to eHealth's 2024 Short-Term Health Insurance Index, the average monthly premium for a 40-year-old is $198, compared to $477 for the cheapest ACA bronze plan. For a 30-year-old, the gap widens: $145/month for short-term vs. $345/month for ACA.

Case study: Maria, 32, graphic designer Maria lost her employer-sponsored insurance when she left her job in January 2025. She needed coverage for 4 months until her new job's benefits kicked in. An ACA bronze plan would have cost $1,380 over 4 months. She chose a short-term plan from UnitedHealthcare for $168/month (total $672), saving $708. She had no medical claims during that period.

2. Quick Enrollment and No Open Enrollment Restrictions

You can enroll in a short-term plan 365 days a year—no special enrollment period required. Application takes 10–15 minutes, and coverage can start as soon as 24–48 hours after approval. This is critical if you:

• Miss the ACA open enrollment (Nov 1–Jan 15)
• Lose job-based coverage unexpectedly
• Graduate from college and lose student health insurance
• Are between ages 26–30 and aging off a parent's plan

3. Flexible Coverage Duration

Unlike ACA plans that lock you in for a full calendar year, short-term plans let you choose coverage from 30 days to 364 days. You can cancel anytime without penalty, unlike ACA plans where cancellation may trigger a tax penalty (though the individual mandate penalty was reduced to $0 at the federal level in 2019).

4. No Provider Networks (Freedom of Choice)

Most short-term plans operate on a fee-for-service model. You can see any licensed doctor, specialist, or hospital. After meeting your deductible, the plan reimburses you at a set percentage (typically 50–80%). This is ideal for travelers or people who prefer out-of-network providers.

5. Catastrophic Coverage for Healthy Individuals

For young, healthy people with no pre-existing conditions, short-term plans function as catastrophic coverage. If you're hospitalized for an accident (e.g., broken leg from skiing), the plan covers 80% of costs after your deductible, up to the maximum benefit. Without insurance, a simple broken leg costs $7,500–$10,000 (Healthcare Bluebook, 2024). With short-term insurance, your out-of-pocket might be $2,000–$3,000.

What Are the Cons of Short-Term Health Insurance?

1. Pre-Existing Condition Exclusions (The Biggest Risk)

Short-term plans exclude pre-existing conditions entirely. The NAIC model law defines a pre-existing condition as any medical condition for which you received medical advice, diagnosis, care, or treatment in the 12 months before applying. This includes:

• Diabetes, hypertension, asthma
• Cancer (even if in remission)
• Pregnancy (considered pre-existing)
• Mental health conditions
• Allergies requiring prescription medication

Real-world example: John, 45, applied for a short-term plan in 2024. He had mild hypertension controlled by medication ($15/month generic). The carrier denied coverage for any cardiovascular-related claims. Six months later, he had a heart attack. The plan paid $0 for his $78,000 hospital bill because it was deemed related to a pre-existing condition.

2. No Essential Health Benefits Required

ACA plans must cover 10 essential health benefits (EHBs). Short-term plans are exempt. Here's what you won't get:

• Maternity and newborn care (average cost: $18,329 for uncomplicated vaginal delivery, Kaiser Family Foundation 2024)
• Mental health and substance use disorder services (therapy session: $100–$250)
• Prescription drug coverage (many plans exclude all medications)
• Preventive services (annual physicals, vaccines, screenings)
• Pediatric services (including vision and dental)
• Rehabilitative services (physical therapy)

3. Annual and Lifetime Benefit Caps

ACA plans have no annual or lifetime limits. Short-term plans typically cap benefits at $500,000 to $2 million. For a serious illness like cancer, treatment costs average $150,000–$200,000 per year (American Cancer Society, 2024). A $2 million cap sounds high, but a single hospitalization for a heart attack can cost $50,000–$100,000, and chemotherapy runs $10,000–$30,000 per month.

4. No Guaranteed Renewability

Short-term plans are not guaranteed renewable. After your policy term ends (e.g., 364 days), the carrier can:

• Refuse to renew your policy
• Increase your premium by 50–300%
• Add new exclusions based on claims you made

Data point: A 2023 study by the Commonwealth Fund found that 27% of short-term policyholders who tried to renew were denied or faced premium increases exceeding 100%.

5. Limited Coverage for Routine Care

Even if you have a claim, short-term plans typically exclude routine checkups, screenings, and immunizations. An annual physical costs $150–$300 out-of-pocket. A mammogram costs $200–$500. A colonoscopy (age 45+) costs $2,000–$5,000 without insurance.

Short-Term vs. ACA Plans: Which Is Better for You?

Feature	Short-Term Health Insurance	ACA Marketplace Plan
Monthly Premium (40-year-old)	$120–$350	$456–$600+ (bronze)
Deductible	$2,500–$10,000	$0–$8,700 (bronze)
Pre-existing Conditions	Excluded entirely	Covered (guaranteed issue)
Essential Health Benefits	None required	All 10 EHBs covered
Maximum Coverage	$500K–$2M per term	No annual/lifetime limit
Renewal Guarantee	No (carrier can deny)	Yes (guaranteed renewal)
Enrollment Period	Any time	Open enrollment (Nov 1–Jan 15)
Subsidies Available	No	Yes (premium tax credits)
State Restrictions	Banned in 14 states	Available in all states
Best For	Healthy, temporary gaps	Ongoing coverage, chronic conditions

Key takeaway: If you qualify for ACA subsidies (income under $60,000/year for a single person), the effective premium for a bronze plan may be $0–$200/month—often cheaper than short-term insurance. Use the Kaiser Family Foundation subsidy calculator to check.

Who Should Buy Short-Term Health Insurance?

Short-term plans are appropriate for:

1. Healthy individuals between jobs (gap of 1–6 months)
2. Recent graduates aging off parent's plan (age 26)
3. People waiting for ACA open enrollment (Nov 1–Jan 15)
4. Travelers needing temporary coverage in another state
5. Young adults (ages 20–35) with no chronic conditions
6. High-income earners who don't qualify for ACA subsidies

Actionable step: If you're between jobs, calculate your gap period. If it's less than 6 months and you have no pre-existing conditions, a short-term plan may save you $1,000–$3,000 compared to COBRA (which costs $600–$1,200/month for individual coverage).

Who Should Avoid Short-Term Health Insurance?

Avoid short-term plans if you:

1. Have any pre-existing condition (diabetes, asthma, hypertension, mental health issues, cancer history)
2. Are pregnant or planning pregnancy (maternity care excluded)
3. Take regular prescription medications (most plans exclude drug coverage)
4. Need mental health or substance abuse treatment
5. Are over age 50 (premiums rise steeply; a 55-year-old pays $300–$600/month)
6. Live in a state that bans short-term plans (CA, NY, MA, NJ, CT, RI, VT, NH, MD, DC, CO, WA, OR, HI)

Case study: Sarah, 28, with asthma Sarah had mild asthma controlled by an inhaler ($50/month). She bought a short-term plan for $130/month to save money. When she had an asthma attack requiring an ER visit ($3,200 bill), the plan denied coverage, citing her pre-existing condition. She paid $3,200 out-of-pocket—more than the $1,200 she saved on premiums.

Actionable step: If you take any prescription medication, call the carrier's customer service and ask: "Do you cover [your medication]?" Get the answer in writing. If they say no, do not buy the plan.

How to Choose the Best Short-Term Health Insurance Plan

Follow this 5-step process:

Step 1: Confirm Your State Allows Short-Term Plans

Check your state's insurance department website. In 2025, 14 states ban them, 8 states restrict to 3–6 months, and 28 states allow 364-day terms.

Step 2: Compare at Least 3 Carriers

Major carriers include:

• UnitedHealthcare (Gold, Silver, Bronze tiers)
• Pivot Health (up to $5M coverage)
• National General (Accident & Health)
• Everest (formerly Aetna STLDI)

Step 3: Read the "Exclusions and Limitations" Section

Look for these red flags:

• "Pre-existing condition exclusion period" (most have 12-month lookback)
• "No coverage for [specific condition]"
• "Maximum benefit per injury/illness" (some plans cap at $50,000 per condition)

Step 4: Calculate Your Total Cost

Use this formula:

Total cost = Premium × months + deductible + copays

Example: $200/month × 6 months = $1,200 premium + $5,000 deductible = $6,200 maximum out-of-pocket

Compare to ACA bronze plan: $450/month × 6 months = $2,700 premium + $8,700 deductible = $11,400 maximum out-of-pocket

Step 5: Check for "Renewal Guarantee" Language

Some carriers offer guaranteed renewability for an additional 10–20% premium. This protects you from being dropped after a claim. If available, consider adding it.

What Are the Hidden Risks and Exclusions?

1. The "Look-Back Period" Trap

Most short-term plans exclude conditions treated in the 12 months before application. But some carriers use a 5-year look-back for certain conditions like cancer or heart disease. Always ask: "What is your look-back period for pre-existing conditions?"

2. Balance Billing Risks

Short-term plans often reimburse at 70% of "usual and customary" charges. If a hospital charges $10,000 for an ER visit and the plan's allowed amount is $5,000, the plan pays 70% of $5,000 = $3,500. You owe the remaining $6,500 (the $5,000 not covered plus the $1,500 balance bill). This is called balance billing and is illegal for ACA plans but allowed for short-term plans.

3. No Coverage for Preventive Care

A 2024 Kaiser Family Foundation survey found that 68% of short-term plans excluded all preventive care. This means no free annual physicals, mammograms, colonoscopies, or vaccinations. You'll pay $150–$500 per screening out-of-pocket.

4. Prescription Drug Exclusions

82% of short-term plans exclude prescription drug coverage entirely, according to a 2023 Commonwealth Fund analysis. For common medications like:

• Insulin: $300–$600/month
• Statins: $50–$200/month
• Antidepressants: $50–$150/month
• Inhalers: $100–$400/month

You'll pay full retail price.

5. No Coverage for Maternity Care

The average cost of a vaginal delivery in the U.S. is $18,329 (Kaiser Family Foundation, 2024). A C-section costs $27,000–$35,000. Short-term plans explicitly exclude pregnancy and childbirth. If you become pregnant while covered, you'll have no maternity benefits and will need to switch to an ACA plan during the next open enrollment.

Frequently Asked Questions

1. Can I buy short-term health insurance if I have a pre-existing condition?

No. Short-term plans exclude pre-existing conditions entirely, using a 12-month look-back period (some carriers use 5 years). If you have diabetes, asthma, hypertension, cancer history, or any chronic condition, you will be denied coverage for related claims. Consider an ACA plan instead, which guarantees coverage for pre-existing conditions.

2. How long can I keep short-term health insurance?

As of 2025, the maximum initial term is 364 days under federal law. You can renew for up to 36 months in most states. However, 14 states ban short-term plans entirely, and 8 states limit coverage to 3–6 months. Check your state's regulations. After your policy term, the carrier can refuse renewal or increase premiums.

3. Is short-term health insurance cheaper than COBRA?

Yes, significantly. COBRA typically costs $600–$1,200/month for individual coverage (the full premium plus 2% administrative fee). Short-term plans average $120–$350/month. However, COBRA covers pre-existing conditions and includes all essential health benefits. For a healthy person with a short gap (under 6 months), short-term insurance is usually the better financial choice.

4. Does short-term health insurance cover doctor visits and prescriptions?

Most short-term plans do not cover routine doctor visits (annual physicals, sick visits) or prescription drugs. A 2023 Commonwealth Fund study found that 82% of short-term plans excluded prescription drug coverage. Some plans offer optional "wellness riders" for an extra $20–$50/month, but these are limited. You'll pay out-of-pocket for most non-emergency care.

5. Can I use short-term health insurance with an HSA?

Yes, but only if the plan qualifies as a high-deductible health plan (HDHP) under IRS rules. For 2025, an HDHP must have a minimum deductible of $1,650 for individual coverage. Most short-term plans meet this threshold. However, you can only contribute to an HSA if you have no other health coverage (including an ACA plan or Medicare). Check with your tax advisor.

6. What happens if I get sick while on short-term insurance?

If you develop a new illness (not pre-existing), the plan will cover it up to your policy's maximum benefit. However, if the illness is related to a pre-existing condition, you'll pay 100% of costs. Also, if your policy ends while you're still being treated, the carrier may refuse renewal, leaving you uninsured with ongoing medical bills.

7. Are there any states where short-term health insurance is illegal?

Yes. As of 2025, 14 states ban short-term health insurance: California, New York, Massachusetts, New Jersey, Connecticut, Rhode Island, Vermont, New Hampshire, Maryland, Washington D.C., Colorado, Washington, Oregon, and Hawaii. Additionally, 8 states restrict coverage to 3–6 months: Arizona, Delaware, Florida, Illinois, Maine, Minnesota, Pennsylvania, and Virginia. Always verify with your state's insurance department.
