About Montana Medicaid
Montana Medicaid provides crucial health coverage for many residents. You generally qualify if you're an adult with a household income up to 138% of the Federal Poverty Level (FPL). For a single adult in 2025, that's approximately $21,597 annually, or about $1,735 per month. For a household of two, the monthly income limit is around $2,344, and for a family of four, it's about $3,563 per month. Children can qualify with higher income limits, up to 148% FPL, and pregnant women up to 162% FPL. Additionally, seniors and individuals with disabilities may also be eligible, often with specific income and asset limits. As of 2024, approximately 232,400 Montanans were covered by Medicaid, demonstrating it's a significant and active program.
If your income is near the Medicaid cutoff, your eligibility could shift between Montana Medicaid and marketplace subsidies on HealthCare.gov. For example, if your income is slightly above 138% FPL, you might qualify for substantial subsidies to help you afford a plan on the marketplace. With Montana's benchmark Silver plan at $536/month, subsidies can significantly reduce your actual monthly payment. It's important to remember that income changes, even small ones, can impact your eligibility, potentially moving you from one program to the other. If you lost Medicaid coverage during the recent "unwinding" period, you can reapply at any time. Many people were disenrolled due to administrative reasons, such as not returning requested information, so reapplying is always an option if your circumstances change or you believe there was an error.
Montana Medicaid offers comprehensive benefits, including doctor visits, hospital stays, prescription drugs, and mental health services. Generally, there are no premiums for those below 100% FPL, and cost-sharing (like copayments) is limited to ensure affordability, not exceeding 5% of your quarterly household income. Montana also has specific waiver programs, such as the Big Sky Waiver, which helps seniors and individuals with physical disabilities receive home and community-based services to avoid nursing home care. Another is the Comprehensive Waiver (0208) for individuals with intellectual or developmental disabilities. These waivers allow for services like personal care, homemaker services, and even environmental modifications to your home.
When navigating Montana Medicaid, be aware that processing delays for applications have been an issue, with some applications taking longer than the federal 45-day guideline. Accurate and complete documentation is crucial for a smooth application process. You'll need information like pay stubs, bank account details, and social security numbers for household members. During the recent unwinding of continuous Medicaid coverage, many Montanans lost coverage, sometimes due to administrative errors or not responding to renewal requests. If you're applying or reapplying, make sure your contact information is up to date with the Department of Public Health and Human Services. Your concrete action step is to visit apply.mt.gov or HealthCare.gov to start an application and see what you qualify for.

If your household income falls below the 138% FPL column, you qualify for Montana Medicaid. If your income is between 138% and 400% FPL, you qualify for ACA marketplace subsidies to help pay for private insurance.
The benchmark Silver plan in Montana costs about $536/month before subsidies, which is in line with the national average. Subsidies can significantly reduce this cost for qualifying households.
Marketplace Insurance in Montana
Montana residents who do not qualify for Medicaid can purchase private health insurance through the federal marketplace at HealthCare.gov. The average benchmark (second-lowest cost Silver) plan in Montana costs approximately $536/month for a 40-year-old in 2026.
Premium tax credits (subsidies) are available for households with income between 100% and 400% FPL. Here is what a 40-year-old individual in Montana might pay after subsidies:
| Income Level | Annual Income | Expected Contribution | Estimated Monthly Premium |
|---|---|---|---|
| 150% FPL | $23,475 | 4.01% of income | ~$78/mo |
| 200% FPL | $31,300 | 6.52% of income | ~$170/mo |
| 250% FPL | $39,125 | 8.33% of income | ~$272/mo |
| 300% FPL | $46,950 | 9.83% of income | ~$385/mo |
| 400% FPL | $62,600 | 9.83% of income | ~$513/mo |
These are estimates for an individual. Actual premiums depend on your age, household size, tobacco use, and the specific plan you choose. Households with income between 100-250% FPL also qualify for cost-sharing reductions (CSR) on Silver plans, which lower deductibles and copays.
Residents of Montana shop for marketplace insurance through HealthCare.gov, the federal exchange. The application process screens for Medicaid eligibility first, so you'll be directed to Montana's program if you qualify.
Since expanding Medicaid, Montana has enrolled hundreds of thousands of adults in Montana Medicaid. Residents whose income fluctuates around the 138% FPL threshold can move between Medicaid and subsidized marketplace coverage as their circumstances change.
