What Are the Montana Short-Term Health Insurance Rules?

Short-term health insurance in Montana is shaped by three layers of rules: federal rules, Montana insurance law and what each insurer files with the Montana Commissioner of Securities and Insurance.

Short-term plans are not required to follow the Affordable Care Act. They can ask health questions, decline applicants, exclude pre-existing conditions and leave out benefits like maternity care. In exchange, premiums are often lower than full-price ACA plans.

How Long Can a Short-Term Plan Last in Montana?

A 2024 federal rule limited new short-term plans to a 3-month first term and 4 months in total. On August 7, 2025, the Departments of Labor, Health and Human Services and the Treasury said they would not prioritize enforcing that rule and plan to revisit it. Federal regulators have said a new rule is expected, so check for updates before you buy.

Montana plans through UnitedHealthcare last up to 6 months. If you need coverage longer than that, compare ACA plans at the next open enrollment or after a qualifying life event.

Short-term plans from UnitedHealthcare are not renewable. If you need more time, you apply again and answer health questions again.

What Short-Term Plans in Montana Usually Do Not Cover

Every plan is different, so read the plan brochure before you buy. Common exclusions and limits include:

• Pre-existing conditions, often defined as conditions treated or diagnosed in the 24 months before coverage starts.
• Maternity and newborn care for a pregnancy that began before coverage.
• Limited mental health and substance use treatment.
• Limited or no prescription drug coverage on some plans.
• Preventive care that ACA plans cover at no cost.
• A maximum benefit, such as a per-policy limit, instead of unlimited coverage.

• Between jobs: while you wait for a new employer plan to start.
• Instead of COBRA: if you are healthy and COBRA is too expensive. Compare COBRA vs short-term health insurance.
• Early retirement: healthy adults waiting for Medicare at 65.
• Moving to Montana: while you set up longer-term coverage.

How Much Does Short-Term Health Insurance Cost in Montana?

Prices depend on your age, ZIP code, the deductible and coinsurance you choose, the benefit maximum and how long you need coverage. Short-term premiums are often lower than unsubsidized ACA premiums because the plans cover less and screen for health.
