Short-term health insurance plans are one of those options that look attractive on paper and require a much closer look before you commit to one. The premium can be 50 to 80 percent lower than an ACA marketplace plan, which sounds compelling when you are staring down a $600 monthly bill for coverage you need to bridge a gap between jobs or during a slow quarter.
The catch is in what that lower price actually buys you, which is considerably less than most people assume when they see the monthly cost. This guide covers what short-term plans are, what changed about them in 2026, what they genuinely cover and what they do not, and the specific situations where they might make sense despite those limitations.
What Short-Term Health Insurance Actually Is
Short-term health insurance, formally called short-term limited duration insurance or STLDI, is a category of health coverage that operates outside the ACA’s consumer protection rules. Unlike marketplace plans, short-term plans are not required to cover the ten essential health benefits the ACA mandates. They can deny you coverage based on your health history through a process called medical underwriting. They can exclude conditions you already have. And they have no cap on what you could owe out of pocket in a bad year because there is no required out-of-pocket maximum.
These plans exist for a specific purpose: to provide some level of temporary financial protection during a coverage gap, typically when someone is between jobs, waiting for new employer coverage to start, or otherwise temporarily without access to comprehensive insurance. They are not designed to function as a permanent solution, and regulators and consumer advocates consistently characterize them that way.
What Changed in 2026
The duration rules for short-term plans changed significantly at the federal level. Short-term health insurance plans are now limited to a maximum of 4 months total duration, including renewals, a substantial reduction from prior rules that had allowed them to last up to 364 days in many states and be renewed for up to 36 months in others. This change narrows their practical use case considerably, since the coverage window is now short enough that it genuinely functions only as a bridge rather than a substitute for comprehensive coverage across an entire year. nerdwallet
State availability also matters. Short-term plans are not available in 12 states including California, New York, and Massachusetts, which have enacted their own regulations either banning or severely restricting them. If you live in one of those states, short-term coverage is not a realistic option regardless of how the federal rules are structured. nerdwallet
What These Plans Do Not Cover
This is where the honest accounting of short-term plans gets uncomfortable, and it is exactly the information that tends not to appear prominently in the marketing materials.
Based on what major short-term plan providers actually cover: 98 percent of these plans exclude maternity care entirely, 94 percent do not cover adult vaccines, 48 percent have no prescription drug coverage, and 40 percent exclude mental health treatment. Most have no out-of-pocket maximum at all, meaning no ceiling on what you could owe. They check your health history before selling to you. They can say no. They can exclude conditions you already have. ACA plans cannot do any of that. Short-term plans do it routinely. Bluevine
The pre-existing condition issue is particularly significant for anyone who has had a health issue in the past. The definition of pre-existing condition used by short-term plan underwriters is often broad enough to include conditions you had years ago, were treated for and resolved, or were even just diagnosed with without necessarily requiring ongoing treatment. A history of back pain, anxiety, high blood pressure, or any number of common conditions can result in either a denial of coverage or an exclusion rider that removes coverage for anything related to that condition for the duration of the plan.
The absence of an out-of-pocket maximum is worth sitting with for a moment. On an ACA-compliant plan, the maximum you can pay out of pocket in a given year is capped, $9,200 for an individual in 2026. A short-term plan with no out-of-pocket cap could theoretically leave you with unlimited exposure to costs if something serious happens, which somewhat undermines the core purpose of having insurance in the first place.
What Short-Term Plans Do Cover
It is worth being fair about what these plans do provide, since the picture is not entirely negative for the specific situations they are designed for.
Most short-term plans cover emergency care, hospitalization, and surgery for new conditions, meaning conditions that were not pre-existing at the time of enrollment. Urgent care visits, diagnostic tests, and specialist visits are commonly covered as well, though the cost-sharing structure varies significantly by plan and the network may be more limited than what an ACA plan provides.
For someone who is genuinely healthy, has no pre-existing conditions, and needs a temporary bridge for a few months while waiting for other coverage to begin, a short-term plan does provide meaningful financial protection against the kind of unexpected acute event, a broken bone, an emergency appendectomy, a car accident, that represents the most expensive unplanned health event a young, healthy person is likely to face.
The Honest Cost Comparison
The premium savings look significant in isolation. Short-term plans often cost 50 to 80 percent less than traditional health insurance, which on paper sounds like an obvious win for a freelancer watching their budget during a slow period. nerdwallet
What the comparison ignores is the total financial exposure. A short-term plan with a $5,000 deductible, no prescription coverage, no mental health coverage, and no out-of-pocket cap sitting alongside a $120 monthly premium does not represent $120 per month of actual health protection. It represents protection against a narrow slice of potential health events for a person who happens to stay entirely healthy during the coverage period.
When you compare the realistic total cost of a short-term plan, premium plus the out-of-pocket you would pay for any service the plan excludes, against a subsidized ACA marketplace Bronze plan with a higher premium but guaranteed coverage for all essential health benefits, the math often favors the marketplace plan unless your income is above the subsidy threshold entirely.
When a Short-Term Plan Actually Makes Sense
Being honest about the limitations does not mean short-term plans have no legitimate use case. They do, and it is narrow.
If you are waiting for ACA Open Enrollment to open and need coverage for two to four months in the interim, you are healthy with no pre-existing conditions, and you have enough savings to cover the deductible if something minor happens, a short-term plan provides reasonable protection at a lower monthly cost for that specific window. The new four-month maximum aligns fairly well with this use case.
If you just left a job and are deciding whether to use COBRA or find other coverage while you assess your freelance income situation, a short-term plan covering the next few months while you figure out your income picture and subsidy eligibility could make financial sense, particularly if COBRA’s full premium is expensive and your qualifying life event window for a marketplace SEP is still open.
If you are in a state where short-term plans are available, are between 30 and 45 with no significant health history, and your income sits above the ACA subsidy threshold making marketplace coverage expensive without any financial assistance, a short-term plan for a defined transition period is a more defensible choice than it would be at any other income or health situation.
What to Consider Before Buying One
Read the exclusions section of any short-term plan document before applying, not after. The marketing materials describe what the plan might cover. The exclusions section describes what it definitely will not. Pay particular attention to how broadly the plan defines pre-existing conditions, since this is where people most commonly discover their coverage is less useful than they expected after a claim is denied.
Check whether the plan is available in your state. If you live in California, New York, Massachusetts, New Jersey, Washington, or several other states with their own short-term plan restrictions, the plan may not be available or may be governed by different rules than what you read in a national comparison.
Confirm the exact duration, including any renewal limitations, before assuming a plan covers you for the full period you need. Under 2026 federal rules, four months is the maximum, but the specific plan you are looking at may be shorter, and some states have stricter limits than the federal maximum.
Alternatives Worth Considering First
Before committing to a short-term plan, there are two alternatives worth checking against your specific situation.
Medicaid has no enrollment window and accepts applications year-round in states that have expanded it under the ACA. If your income for the year is projected to fall below roughly 138 percent of the federal poverty level, which is approximately $20,800 for a single person in most states, Medicaid likely covers you at little or no cost and provides ACA-compliant coverage without the exclusions short-term plans carry.
A marketplace plan through a Special Enrollment Period is available if you have a qualifying life event, which for most new freelancers means the loss of prior employer coverage. Leaving a job to go freelance is itself a qualifying event, giving you a 60-day window to enroll in a marketplace plan regardless of where Open Enrollment stands on the calendar. For most freelancers below the 400 percent federal poverty level income threshold, this option with subsidies will be more financially sensible than a short-term plan even in the months before Open Enrollment opens.
Frequently Asked Questions
Can a short-term plan deny my claim after I already enrolled?
Yes. Short-term plans use medical underwriting when you apply, but they also reserve the right to investigate claims and deny them if they determine the condition being treated was pre-existing at the time of enrollment, even if that determination is made after you filed the claim. This is one of the practices that distinguishes them from ACA-compliant plans, which cannot use health history to deny claims for covered services.
Does a short-term plan satisfy the ACA individual mandate?
The federal ACA individual mandate penalty has been at zero since 2019, so there is no federal penalty for going without ACA-compliant coverage. However, some states have their own individual mandates with financial penalties, including California, Massachusetts, New Jersey, Rhode Island, and Washington D.C. In those states, a short-term plan does not satisfy the mandate and the penalty still applies.
Is there a difference between short-term health insurance and a health sharing ministry?
Yes. Health sharing ministries are faith-based cost-sharing arrangements where members contribute monthly and funds are distributed to cover eligible medical expenses. They are not insurance and operate under different legal frameworks. Like short-term plans, they are not ACA-compliant and typically exclude pre-existing conditions and certain categories of care, but the structure and the specific exclusions differ significantly between the two.
If I need coverage for exactly four months, is a short-term plan or COBRA better?
COBRA provides ACA-compliant coverage, meaning it covers pre-existing conditions, essential health benefits, and carries an out-of-pocket maximum. The trade-off is cost: COBRA requires you to pay the full employer premium plus a 2 percent administrative fee, which is often significantly more expensive than a short-term plan. If you have no pre-existing conditions and the specific coverage gap is the only concern, a short-term plan costs less. If you have ongoing health needs, prescriptions, or any history of significant conditions, COBRA’s comprehensive coverage is worth the higher price to avoid the exclusions a short-term plan will almost certainly impose.
Final Thoughts
Short-term health insurance is exactly what the name says: a temporary bridge, not a health coverage strategy. The 2026 rule limiting these plans to four months total is a reflection of that intended purpose, and the coverage they provide within that window is meaningful only for people who are healthy enough that the extensive exclusion lists are unlikely to affect them. For most freelancers with any health history, prescriptions, or ongoing care needs, an ACA marketplace plan through a Special Enrollment Period or, if income qualifies, through Medicaid is a significantly better option even when the short-term premium looks attractive by comparison. If you have no qualifying life event and need to bridge a specific gap while genuinely healthy, a short-term plan can serve that narrow purpose, but go into it with a clear understanding of what it will not cover before you need to find out from a denied claim.
