Short-term health plans are priced like catastrophe coverage because that is essentially what they are. ACA Marketplace plans are priced like comprehensive coverage because federal law requires them to be. The difference is not just the monthly premium. It is what each type of plan will and will not pay when something actually goes wrong.
Key Takeaways
- Short-term limited duration insurance (STLDI) is not ACA-compliant. Insurers can underwrite applicants based on health history, exclude pre-existing conditions, and cap benefits in ways that Marketplace plans cannot.
- STLDI does not qualify for APTC or CSR. A subsidy-eligible client who buys a short-term plan loses every dollar of the federal tax credit for those months.
- Short-term plans can cost 30 to 60 percent less than ACA gross premiums for a healthy adult. Once APTC is factored in, the net ACA cost often undercuts the short-term premium significantly.
- Duration limits, renewal rules, and state availability have changed multiple times since 2017 under different administrations. Verify current federal and state rules before quoting STLDI in any market.
- Losing a short-term plan does not trigger a Marketplace SEP. STLDI is not minimum essential coverage. A client whose short-term plan expires and who misses OEP is stuck waiting for a qualifying event.
What makes a short-term plan short-term
Short-term limited duration insurance (STLDI) sits outside the ACA requirements entirely. Insurers writing STLDI can underwrite applicants based on health history, decline coverage for pre-existing conditions, limit benefits by dollar amount, and exclude entire categories of care that every Marketplace plan must cover. The term "short-term" refers to plan duration, not the size of the coverage gap it leaves.
The key legal fact: STLDI does not meet the ACA definition of minimum essential coverage. That one distinction drives most of the downstream consequences for clients who buy it. No APTC. No SEP when it ends. No ACA OOP cap. The plan exists in a different regulatory category entirely.
Federal rules on maximum STLDI duration and renewal have changed multiple times since 2017. State laws add another layer of variation. Some states prohibit short-term plans outright. Others cap the term at a few months. Confirm what is currently permitted in the client's state before quoting any STLDI product.
Side by side: STLDI vs ACA Marketplace
| Factor | Short-term plan (STLDI) | ACA Marketplace |
|---|---|---|
| ACA-compliant? | No. Does not meet minimum essential coverage (MEC) requirements under federal law. | Yes. All Marketplace plans are ACA-compliant and count as MEC. |
| Essential health benefits | Not required. Most plans exclude mental health, maternity, and prescription drug coverage. | All 10 EHB categories required. Plans cannot limit or exclude them. |
| Medical underwriting | Permitted. Applicants can be denied or excluded for pre-existing conditions. | Prohibited. Community rating applies. No denial for pre-existing conditions. |
| APTC and CSR eligible | No. Federal tax credits are not available on non-Marketplace plans. | Yes, for households between 100 percent and 400 percent FPL (and beyond for premium cap). |
| Monthly premium (illustrative) | Lower gross premium for healthy applicants. Can be 30 to 60 percent below ACA gross. | Higher gross premium. Net cost after APTC is often lower than STLDI for eligible households. |
| Out-of-pocket maximum | Not subject to ACA OOP limits. Benefit caps and coverage limits vary by plan. | Capped at the CMS annual OOP maximum for the plan year. No benefit dollar caps allowed. |
| Loss of coverage triggers Marketplace SEP? | No. Losing STLDI does not create a qualifying life event or SEP. | Yes. Loss of Marketplace coverage triggers a 60-day SEP. |
The subsidy math usually settles the question
For subsidy-eligible clients, the comparison rarely stays close once APTC is applied. The short-term plan looks cheaper on the gross premium. It is not cheaper on the net cost for most clients in the subsidy range.
To illustrate: a 35-year-old considering health coverage after leaving a job.
At 220 percent FPL, the gross ACA Silver premium might be $430 per month. A short-term plan for the same applicant might list at $175. The gross gap looks like $255 in the short-term plan's favor. With APTC applied, the net Silver cost could be $90 to $110 per month depending on the rating area. The short-term plan is now more expensive and covers less.
Above 400 percent FPL with no meaningful APTC, the comparison shifts. A healthy adult in their 30s paying full gross Marketplace rates may find the short-term plan materially cheaper. Whether the coverage trade-off is acceptable is a different conversation.
Illustrative example only. Actual premiums, APTC amounts, and plan options depend on rating area, household size, income, and the specific plan year. Subsidy and premium estimates should be verified with current CMS data before making any recommendation.
Coverage gaps that show up at claims time
Most clients who ask about short-term plans are focused on the monthly cost. The questions they are not asking are the ones that matter: what does this plan actually cover, and what does it not cover?
STLDI plans are not required to include the ten essential health benefit categories that every Marketplace plan must cover. Mental health services, substance use treatment, maternity care, and prescription drug coverage are commonly excluded or severely limited. A client who buys a short-term plan and later needs inpatient mental health treatment or maternity care may find that the plan pays nothing. For more on the EHB categories that ACA plans must cover, read essential health benefits: what every ACA plan must cover.
Pre-existing condition exclusions are another common exposure. A client who disclosed a prior diagnosis during underwriting and was accepted may still find that condition excluded from coverage. The exclusion language in STLDI policies tends to be broad. A client with diabetes buying a short-term plan may find that any hospitalization with diabetes as a contributing factor is denied.
Three narrow situations where STLDI merits discussion
Clients who are not subsidy-eligible, who are healthy, and who face a specific short-term coverage gap with no other MEC option available are the realistic STLDI candidates. That is a narrower group than the premium comparison alone suggests.
Missed OEP with no qualifying event.A client who let their Marketplace plan lapse, missed OEP, and has no qualifying life event has no path to a Marketplace plan until the next OEP. If the gap is a few months and the client is healthy and not subsidy-eligible, a short-term plan may be the only option until OEP opens again. The broker's job is to explain the coverage limitations before the client signs.
High income, healthy, specific gap. A client with household income above 400 percent FPL who loses employer coverage and has a known short-term gap before new employer benefits begin may find short-term coverage preferable to full ACA gross premiums for a few months. The OOP exposure is the tradeoff. It should be stated explicitly.
Bridge to OEP with a clear end date. A client who knows their STLDI plan will expire exactly when OEP opens and who can enroll during OEP is using the product as a true bridge. The risk is the SEP gap: if the client has any coverage event between STLDI expiry and their planned OEP enrollment, they cannot enroll early because the STLDI expiry is not a qualifying event.
What to tell the client who asks about short-term plans
The client asking about short-term plans is usually looking for a cheaper option. The right response is not a policy lecture. It is the actual net cost comparison.
Pull the subsidy estimate first. If the client is APTC-eligible, run the net Marketplace cost before mentioning STLDI as an option. For most clients in the subsidy range, the net ACA cost undercuts the short-term premium and comes with comprehensive coverage. The conversation usually ends there.
Multi-line quoting platforms like Quotit include STLDI in their product catalog alongside ACA. For brokers writing multiple lines, that integration can simplify quoting. For a broker whose book is predominantly ACA-focused, the STLDI option is a last resort, not a starting point. Defaulting to a short-term plan for a subsidy-eligible client who did not understand the options is an avoidable outcome.
If STLDI is the right answer after running the numbers, walk the client through the exclusion list, the benefit caps, and the fact that losing the plan will not trigger an SEP. The plan details that seem fine in month one are the ones that cause problems in month seven.

FAQ
Common questions brokers and clients ask when comparing short-term health plans against ACA Marketplace options.
Can a client collect APTC and buy a short-term plan at the same time?
No. APTC is only available for months a client is enrolled in a qualifying Marketplace plan. A client enrolled in a short-term plan is not collecting APTC for those months. If the client was otherwise eligible for the credit, the subsidy is simply lost for that enrollment period.
Does losing a short-term plan trigger a Marketplace SEP?
No. Short-term limited duration insurance is not minimum essential coverage under the ACA. Only the loss of MEC triggers a qualifying life event and SEP. A client whose short-term plan expires at the end of its term has no SEP trigger from that event and cannot enroll on the Marketplace until OEP unless a separate qualifying event occurs.
Are short-term plans available in all states?
No. Several states have restricted or banned STLDI sales entirely, including California, New York, New Jersey, Massachusetts, and others. States that permit them may impose shorter duration limits than the current federal rules allow. Confirm availability and maximum plan duration for the client's state before quoting.
Who is a reasonable candidate for a short-term plan?
The list is narrow. A healthy adult who is not subsidy-eligible, who faces a specific coverage gap shorter than OEP timing permits the Marketplace to address, who has already used a SEP or missed OEP, and who cannot access any MEC alternative. Even then, the out-of-pocket exposure warrants an explicit conversation about coverage exclusions before the client signs.
Do short-term plans count toward the ACA coverage requirement?
No, STLDI does not count as minimum essential coverage for ACA purposes. The federal individual mandate penalty has been $0 since 2019, so there is no federal tax consequence for lacking MEC. Some states have their own individual mandate with state penalties. Check the client's state rules separately.
