Short-Term Health Insurance Rules by State: Where It’s Banned, Capped, or Freely Sold in 2026

Short-term health insurance is regulated by both federal and state law, and the result is a patchwork: the same product that costs $120 a month for 11 months in one state is illegal in the next. Federal rules set a ceiling — roughly four months per policy and twelve months total with renewals — but states layer bans, shorter caps, and renewal restrictions on top. Before you shop, know which of the four regulatory worlds you live in.

The Four Regulatory Worlds

State rules change; verify with your state insurance department before purchase. The list above reflects 2026 published summaries.

What “Banned” Actually Means for You

In ban states, quote engines still show you “short-term-style” products — they are fixed-benefit indemnity plans (pay $X per doctor visit, $Y per hospital day) that skirt the definition of short-term medical. They are not equivalents: a hospital-day benefit of $1,500 against a $9,000/day hospital bill is not cost-sharing, it’s a coupon. Ban states usually pair the ban with their own marketplace and expanded subsidies — California (Covered California), New York, New Jersey, and Colorado all have state subsidy programs that frequently beat any private gap product for legal residents under the income thresholds.

How Caps Change Strategy in Cap States

A 3-month cap converts the product from “bridge insurance” to “gap insurance.” The practical effects:

• Buy only the gap you have. You cannot pre-buy a year and cancel; a 6-month planned gap needs two policies and two underwriting events — with a fresh look-back window and possibly new exclusions each time.
• The renewal problem: where renewals are prohibited, a denied claim in month three leaves you uninsured with no in-category replacement until the next underwriting pass — which now includes the new condition. Plan your exit to a real plan (marketplace, employer, Medicare) before the term ends.
• Price effects: shorter maximum terms remove long-duration discounts; expect slightly higher monthly rates than the national averages quoted for Texas or Florida.

State-Specific Details Worth Knowing

Texas and Florida (federal baseline)

Full-term availability, big carrier menus, and the national price table apply. Both states have large uninsured populations, and short-term products are heavily marketed — which makes the exclusion-list literacy from the rest of this site more important, not less.

States with special renewal frameworks

A few states historically allowed longer initial terms; after the 2024 federal rule, federal law preempts longer state allowances on duration, so the effective national maximum is the federal ~4/12 structure. Where you see “up to 12 months” advertised, read whether it means one policy (rare now) or renewable stack (common).

The Moving Family Problem

Remote workers and relocations create a rule most shoppers never consider: the state of your residence at application controls, and moves mid-term can strand coverage. A plan bought in Georgia doesn’t become illegal when you move to New York, but its network (thin PPOs) may be useless in your new state, and you cannot re-up on New York terms. If a move is on the calendar, buy coverage that ends at the move and use the relocation itself as an ACA special enrollment trigger — moving is a qualifying event.

Frequently Asked Questions

Why do states ban short-term plans?

Healthy people migrate to cheap short-term coverage, leaving ACA pools sicker and premiums higher — a classic adverse-selection argument. Bans are usually paired with state subsidies to close the gap the ban opens.

Can I buy a short-term plan “in” a ban state using another state’s address?

It’s misrepresentation — carriers verify residence for claims, and a claim from your real address can be denied on residency grounds. Don’t.

Are travel medical plans affected by state bans?

No — short-term travel medical (for international trips) is a separate product category and remains available nationwide. But it’s designed for emergencies abroad, not U.S. gap coverage.

Do ban states have alternatives for healthy people between jobs?

How do I verify my state’s current rule?

How to Verify Your State’s Current Rules (Five Minutes, Authoritative)

1. Search “[your state] department of insurance short-term limited-duration.”
2. On the DOI page, look for: sale allowed (yes/no), maximum initial term, renewal rules, and any mandated benefits.
3. If the DOI page is silent, the federal baseline applies (~4-month initial, ~12-month total with renewals under the 2024 federal rule).
4. Cross-check by starting a quote on a major carrier site with your real ZIP — the term-length dropdown is the practical truth of what’s sold where.

The Adverse Selection Cycle: Why the Map Keeps Changing

State rules move with politics and pool economics, typically in one direction: healthy people leaving ACA pools raises marketplace premiums, which increases short-term demand, which prompts restrictions — often paired with new state subsidies to close the loop. New York and California banned early; New Mexico, Washington, and Virginia restricted in recent cycles; several states have pending legislation each session. Practical consequence: re-verify your state’s rules annually, and never build a multi-year coverage strategy on terms this product may not legally offer next year. The federal floor (4/12 structure) is stable; everything above it is negotiable in a statehouse.

Buying Across State Lines: What’s Legal and What’s Not

• Legal: buying from a carrier licensed in your resident state, even if the carrier is headquartered elsewhere. All national short-term carriers work this way.
• Legal: keeping coverage during a temporary relocation (snowbirds, contract workers), though network usefulness will follow the plan’s PPO map, not your suitcase.
• Not legal: purchasing with a relative’s address in another state, or maintaining “residence” fiction to reach a looser state’s terms. Carriers verify residence at claim time through billing addresses, tax documents, and provider locations.
• The clean path for movers: end coverage at the move — a permanent relocation is itself an ACA special enrollment trigger, so the move unlocks guaranteed-issue marketplace access in the new state. The relocation you’re planning is the exit door.

Bottom Line

Your ZIP code is the first question the quote engine asks because it’s the first fact of the product: banned states route you to state marketplaces and subsidy programs; capped states force the buy-short-renew-discipline; federal-baseline states offer the full menu. None of the state categories is “better” for a knowledgeable shopper — they just change which tool the law hands you. Match the tool to the gap, verify annually, and let the move trigger the guaranteed-issue door when relocation comes.
