Short-Term Health Insurance: When It Makes Sense and When It Does Not
Short-term plans get sold as cheap health insurance. They are cheap because they leave things out. Used for the right gap they are smart. Used as a long-term plan they are a trap.
What a short-term plan is
A temporary medical policy that covers unexpected illness and injury for a defined term. It is medically underwritten, starts within days, and costs a fraction of a full plan. Term lengths and renewal rules depend on your state, and federal rules have changed more than once, so I confirm what is currently allowed where you live.
What it does not cover
- Pre-existing conditions. Anything you were treated for before the plan started is typically excluded.
- Maternity, mental health and prescriptions, in whole or in part, depending on the plan.
- Benefit maximums. There is a cap on what the plan pays.
It is not ACA-compliant coverage and does not come with the marketplace's guarantees.
When it is the right call
- A known gap between jobs, when the new employer's plan has a waiting period.
- You missed open enrollment, are healthy, and need something until a private plan is issued or the next window opens.
- COBRA is unaffordable and the gap has an end date.
When it is the wrong call
- You have any ongoing condition or medication.
- You or a partner may become pregnant.
- You are using it as a permanent plan because it is cheap. One serious diagnosis and the benefit cap becomes your problem.
The better long-term alternative
If you are healthy and need coverage year-round, a private medically underwritten plan costs more than short-term but is real, renewable coverage with a nationwide network. For most people I quote the private plan first and only use short-term for a defined bridge.
Frequently asked questions
How fast can a short-term plan start?
Usually within a day or two of approval. That speed is the main reason people use it for a sudden gap.
Can I renew a short-term plan?
It depends on your state and the current federal rules. Some allow renewals up to a limit, some do not. I confirm this before you buy.
Does a short-term plan count as having coverage for a special enrollment period?
No. Ending a short-term plan does not trigger a marketplace special enrollment period.
Is short-term cheaper than COBRA?
Almost always, but COBRA covers everything your old plan covered, including pre-existing conditions. Short-term does not.
