The main difference in tri-term vs. short-term health insurance is how long you're covered and when pre-existing conditions can be covered. A standard short-term plan lasts from one month to just under a year and never covers pre-existing conditions. UnitedHealthcare's TriTerm Medical runs about three years in three terms, and after the first 12 months it may cover eligible care for some pre-existing conditions. If you need a quick bridge, pick short-term. If you need longer coverage outside the ACA, look at TriTerm.
- Short-term plans cover one month to just under 12 months, depending on your state, and can start the next day.
- TriTerm Medical covers up to one day less than three years, split into three terms, and can start in as few as 5 days.
- Neither plan covers pre-existing conditions at first. TriTerm may cover eligible care for some of them after 12 months.
- Both are medically underwritten, use UnitedHealthcare's national network, and are not ACA-compliant coverage.
Tri-Term vs. Short-Term Health Insurance: Side by Side
Both plans are short-term, limited-duration insurance from Golden Rule Insurance Company, a UnitedHealthcare company. Still, they're built for different needs. Here's how they compare.
| Feature | Short-term medical | TriTerm Medical |
|---|---|---|
| Coverage length | 1 month to just under 12 months | About 3 years, in three terms |
| Earliest start | As soon as the next day | As soon as 5 days after you apply |
| Pre-existing conditions | Not covered | Not covered in the first 12 months, then eligible care may be covered |
| Preventive care | Limited | $200 per person per term after a 6-month wait |
| Prescriptions | Many plans include them | Up to $5,000 per person per term |
| Who can apply | Ages 19 to 64 | Primary applicant ages 19 to 63 |
| Premiums | Set for your term | Expected to change in terms 2 and 3 |
How Short-Term Health Insurance Works
A short-term plan fills a gap. For example, you might be between jobs, waiting for employer coverage to start, or past Open Enrollment. You apply any time of year, and coverage can begin as soon as the next day.
Plans cover doctor visits, emergency care, hospital stays and lab work, and many include prescriptions. You choose a deductible, often from $2,500 to $15,000 per person. Then you use UnitedHealthcare's national network, with no referral needed for in-network specialists. Our short-term health insurance guide covers the full plan lineup.
However, short-term plans are medically underwritten. You answer health questions, and the insurer can decline your application. In addition, they don't have to cover the ACA's essential health benefits. Compare the trade-offs in our short-term vs. ACA guide.
How TriTerm Medical Works
TriTerm Medical is UnitedHealthcare's three-year short-term plan. You buy one policy, and it runs in three back-to-back terms that total one day less than three years. In a few states, each term is 364 days.
Because it lasts longer, TriTerm adds benefits most short-term plans don't. Here's what stands out:
- Preventive care. After a 6-month wait in the first term, each person gets $200 per term for wellness checks.
- Prescriptions. Outpatient drugs are covered up to $5,000 per person per term. Some plans charge a $25 copay for tier 1 drugs with no deductible.
- Office visits. On Copay Select Max plans, your first four visits per term cost $50 each.
- Lifetime maximum. Most plans pay up to $2 million per covered person.
Coverage ends at age 65, when Medicare takes over. Learn more on our TriTerm health insurance page, or browse the TriTerm FAQ library.
If you expect to need private coverage for more than a year, price TriTerm first. One application covers all three terms, so you won't have to reapply and requalify every year.
Pre-Existing Conditions: The Biggest Difference
With a standard short-term plan, pre-existing conditions are not covered. That includes conditions you're treating or taking medicine for, past conditions that return, and a pregnancy that began before coverage.
TriTerm works differently over time. No benefits are paid for a pre-existing condition in the first 12 months. After that, eligible services related to some pre-existing conditions may be covered. Even so, some health conditions make applicants ineligible, so apply early and answer every question honestly. Our guide to short-term health insurance and pre-existing conditions explains how underwriting works.

Which One Fits You?
| Your situation | Better fit |
|---|---|
| Between jobs for a few months | Short-term |
| Waiting for employer coverage to start | Short-term |
| Missed Open Enrollment and need coverage now | Short-term, then review ACA options at the next enrollment |
| Self-employed and healthy, need coverage for years | TriTerm |
| Retiring early, a few years from Medicare | TriTerm |
| Have a serious ongoing condition | ACA plan, since short-term plans may not cover it |
Also think about subsidies. If your income qualifies for ACA premium tax credits, a Marketplace plan may cost less than either option and covers pre-existing conditions. Check our health insurance subsidies guide first. Self-employed? See our self-employed health insurance guide too.
Where These Plans Are Available
Short-term plans are sold only in approved states, and each state sets its own length limits. TriTerm is available in fewer states than standard short-term plans. Federal rules changed in 2024, but enforcement of the shorter limits paused in 2025, so many states again allow plans that last up to 36 months.

How TriTerm Works, Term by Term
Because TriTerm runs about three years, it helps to know what changes along the way. Here's a simple view of one policy over time.
| Period | What to expect |
|---|---|
| Months 1 to 6 | Core medical benefits apply. Preventive care is still in its waiting period. |
| Months 7 to 12 | The $200 preventive benefit opens. Pre-existing conditions are still excluded. |
| Term 2 | Premiums may change. Eligible care for some pre-existing conditions may now be covered. |
| Term 3 | Premiums may change again. Coverage ends one day before three years, or at 65. |
A standard short-term plan, by contrast, simply ends on the date you chose. After that, you'd need to reapply or move to other coverage. Plan your next step early, since losing short-term coverage doesn't open an ACA enrollment window.
How to Apply for Either Plan
- Decide how long you need coverage. A few months points to short-term, while a year or more points to TriTerm.
- Pick a deductible. A higher deductible lowers your premium but raises what you pay before benefits start.
- Review the health questions. Answer them honestly, because wrong answers can lead to denied claims.
- Choose a start date. Short-term can start the next day, and TriTerm in about 5 days.
- Read the benefit summary. Check limits on prescriptions, visits and the lifetime maximum.
