Short-Term Health Insurance: What You Need to Know

What Is Short-Term Health Insurance?

Short-term health insurance is temporary coverage designed to fill gaps between longer-term plans. They are available year-round without an enrollment period, and how long one may last is set by a federal definition that has changed twice since 2018 and by your own state’s rules. They cost significantly less than ACA marketplace plans — but come with major limitations.

What Short-Term Plans Don’t Cover

Short-term plans are NOT ACA-compliant. This means they can and do:

• Deny applicants based on pre-existing conditions
• Exclude pre-existing conditions from coverage even after enrollment
• Omit essential health benefits: maternity care, mental health, substance use disorder treatment, and prescription drugs are commonly excluded
• Impose benefit limits: annual and lifetime caps on coverage that ACA plans cannot impose
• Exclude preventive care or cover it with cost-sharing

These are not minor gaps — they represent the majority of the cost risk that health insurance is supposed to protect against.

When Short-Term Insurance Makes Sense

Short-term insurance is most appropriate as a bridge option in narrow circumstances:

• A healthy adult who just missed Open Enrollment and has no qualifying life event, and needs some coverage until next enrollment period
• A gap period between jobs where COBRA is prohibitively expensive and no marketplace SEP has been triggered
• New college graduates who aged off a parent’s plan and have a very limited budget and excellent health

Short-term plans are NOT appropriate for anyone with pre-existing conditions, pregnancy, mental health needs, or regular prescription medications — in these cases, the coverage exclusions leave you exposed to the exact risks you most need to protect against.

How Long These Plans Can Last Is Currently Unsettled

Most articles on this subject state a duration limit as though it were fixed. It is not, and the honest answer changes what you should ask for.

So the 2024 definition — 3 months initial, 4 months maximum — remains on the books, while federal enforcement of it is paused pending a replacement rule. In practice that makes state law the binding constraint, and state law is where you should actually be looking.

Your State Decides, Not the Federal Rule

State approaches range from prohibiting these plans outright to capping them well below the federal figure, and the National Association of Insurance Commissioners notes that more states have been tightening rather than loosening. There is no reliable published count, and it changes, so the only useful answer is a state-specific one.

Of the 23 states where Health Advisory is licensed, availability and maximum duration vary. Confirm both before you buy anything, and confirm them for the state you actually live in rather than the one the website quoting you is based in.

It Is Medically Underwritten, and That Is the Point

Unlike ACA marketplace coverage, a short-term plan can ask about your health and decline you for it. That is precisely how it costs less: the premium reflects the fact that people likely to claim are screened out.

Which means two things follow. If you are healthy, you may well be accepted quickly. If you are not, this market can turn you down — and a decline here is not a decline on ACA coverage, which remains guaranteed issue with no health questions at all. If you want to know what that process involves before you start it, the underwriting questionnaire and declination letter pages set it out.

One more consequence worth stating plainly: these plans are not minimum essential coverage. They do not satisfy any state individual mandate that applies to you, and holding one does not create a special enrollment period when it ends.

Before You Buy One

1. Ask for the maximum duration in your state, in months, in writing.
2. Ask what happens at the end. Renewal is not guaranteed, and re-applying means being underwritten again on your health as it is then — including anything diagnosed while you were covered.
3. Read the pre-existing condition language. Exclusion of prior conditions is normal in this market and is where most of the disappointment lives.
4. Check the dollar caps. Annual and lifetime limits are permitted here and are prohibited on ACA plans.
5. Confirm the enrollment date you are bridging to, so the gap you are covering has a defined end.
