Short-term health insurance (STHI) policies provide temporary coverage for gaps between major-medical plans. They’re cheaper than ACA-compliant plans but offer significantly less protection. Used wisely, they bridge specific gaps. Used as a permanent substitute for full coverage, they create severe financial risk.
This guide explains exactly when STHI makes sense and what risks it carries.
Quick Definition
Short-term health insurance (also called “short-term limited duration insurance” or STLDI) provides temporary medical coverage typically lasting 1 month to 3 years. Plans are not subject to ACA rules.
At a Glance
| Feature | Short-Term Plan | ACA Marketplace Plan |
|---|---|---|
| ACA-compliant | No | Yes |
| Pre-existing conditions covered | Often no | Yes |
| Essential health benefits required | No | Yes |
| Maximum term | Varies by state | N/A (annual) |
| Renewable | Sometimes | Annual renewal |
| Premium | Lower (50–80% of ACA) | Higher |
| Subsidies available | No | Yes |
When Short-Term Plans Win
- Brief coverage gaps (1–3 months between jobs)
- Waiting for employer coverage to start (90-day waiting periods)
- Missed open enrollment with no Qualifying Life Event
- College graduates waiting to start a job
- Recently divorced waiting for own employer coverage
- Healthy people wanting catastrophic protection only
When Short-Term Plans Are Wrong
- Long-term coverage (year+) — ACA plans almost always better
- Pre-existing conditions — usually not covered
- Pregnancy — usually excluded
- Mental health needs — often excluded or capped
- Prescription drug coverage — limited or absent
- Anyone who could qualify for Marketplace subsidies — better protection for similar cost
What Short-Term Plans Often Don’t Cover
| Service | Typical STHI Coverage |
|---|---|
| Pre-existing conditions | Excluded (no coverage) |
| Maternity | Excluded |
| Mental health | Limited or excluded |
| Substance abuse | Limited or excluded |
| Prescription drugs | Limited or separate |
| Preventive care | Limited |
| Pediatric dental/vision | Excluded |
This is the central catch — ACA plans must cover all 10 essential benefits; short-term plans often cover few.
Cost Comparison
35-year-old healthy single person:
| Plan | Monthly Premium | Deductible | What’s Not Covered |
|---|---|---|---|
| ACA Bronze (no subsidy) | $400 | $7,000 | All ACA essentials covered |
| ACA Silver (with $400 subsidy) | $50 | $4,000 | All ACA essentials covered |
| Short-term plan | $150 | $5,000 | Most ACA essentials NOT covered |
If you qualify for ACA subsidies, the Marketplace plan is often cheaper AND offers more coverage.
The Catastrophic Risk
Short-term plans typically have:
- Annual benefit caps (often $500K–$1M lifetime)
- Daily limits on hospitalization
- No coverage for pre-existing conditions discovered during plan term
- Coverage rescission if undisclosed conditions found later
A heart attack or cancer diagnosis can result in tens of thousands in uncovered medical bills with a short-term plan.
State Variations
Short-term plan rules vary widely by state:
| State Approach | Examples |
|---|---|
| Banned entirely | New York, Massachusetts, New Jersey |
| Restricted to short durations | California (3 mo max) |
| Standard 12-month max | Federal default in most states |
| Up to 3 years | Some states (allowed under federal rules) |
Always check your state’s rules before considering STHI.
Better Alternatives to Consider First
Before STHI, evaluate:
- Marketplace Special Enrollment — many life events qualify
- COBRA continuation of employer coverage
- Spouse’s employer plan
- Medicaid eligibility (income-based)
- Healthcare Sharing Ministries — not insurance, but cost-sharing
- Catastrophic Marketplace plans — for under 30 or hardship exemption
The COBRA Comparison
COBRA continues your employer coverage at full premium for up to 18 months. Comparison:
| Factor | COBRA | Short-Term |
|---|---|---|
| Premium | Full employer cost ($600–$2,000+/month) | Much lower |
| Coverage | Same as employer plan | Limited |
| Pre-existing conditions | Covered | Usually not |
| Best for | Active medical needs | Healthy short-term gaps |
COBRA is expensive but full-coverage. Short-term is cheap but limited.

Red Flags in Short-Term Plan Marketing
Watch for misleading claims:
- “Comprehensive coverage” (rarely true)
- “Replaces ACA insurance” (it doesn’t)
- “Same as Marketplace” (it isn’t)
- “All conditions covered” (pre-existing usually excluded)
- Pressure to enroll quickly without reading exclusions
Always read the Summary of Benefits and Coverage (SBC) before enrolling.
How to Buy Short-Term Coverage Wisely
If STHI is the right choice for your gap:
- Confirm your state allows it and for what duration
- Read the exclusions list carefully before signing
- Verify the insurer is licensed in your state
- Don’t undisclose health conditions — this voids the policy
- Set a calendar reminder to find longer-term coverage before STHI ends
- Don’t use STHI if you have known health conditions
FAQ — Short-Term Health Insurance
Q: Is short-term health insurance the same as ACA insurance? A: No — short-term plans don’t comply with ACA rules and don’t cover essential health benefits or pre-existing conditions.
Q: How long can I keep a short-term plan? A: Varies by state and federal rule. Federal allows up to 12 months with extensions to 3 years; some states are more restrictive.
Q: Can I get a short-term plan with a pre-existing condition? A: Usually no — most short-term plans deny coverage for pre-existing conditions.
Q: Are short-term plans cheaper than Marketplace plans? A: They have lower premiums but offer significantly less coverage. With ACA subsidies, Marketplace plans often cost less for far better protection.
Q: When should I avoid short-term plans? A: Long-term coverage needs, pre-existing conditions, planned medical needs, anyone qualifying for Marketplace subsidies.

Bottom Line
Short-term health insurance is a bridge product for brief gaps in coverage — never a permanent substitute for ACA-compliant insurance. If you have any meaningful subsidy eligibility, a Marketplace plan almost always beats short-term on total protection per dollar. Use STHI only for healthy, short-duration gaps where you understand and can afford the catastrophic risk if something goes wrong.
