Medicare in Bozeman: 15 Advantage Plans on Tap for 2026

Medicare options in Gallatin County, Montana: plan counts, key 2027 dates, and where to get unbiased help choosing coverage.

BOZEMAN, Mont. — If you're turning 65 in the Gallatin Valley or already on Medicare and thinking about a change, here's the short version for 2027: you have choices. Bozeman is in Gallatin County, where 15 Medicare Advantage plans were available for 2026, according to the Centers for Medicare & Medicaid Services (CMS) Landscape files. The 2027 lineup is detailed in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder — the starting point for anyone weighing coverage this fall.

What "15 plans" really means in Bozeman

Medicare Advantage availability is set at the county level, not by ZIP code or city. So when we say 15 plans, we mean 15 Medicare Advantage options offered to people who live in Gallatin County — which includes Bozeman, Belgrade, Manhattan, Three Forks, Big Sky and the surrounding communities.

Those 15 plans come from just 3 carriers. That's useful context: it means several plans on your list may be different versions from the same insurance company, with different networks, drug coverage, or extra benefits. When you compare, sort by carrier first so you're not looking at near-duplicates side by side.

The Part D picture is a little different here

Nationally, most counties have a long menu of stand-alone Part D (prescription drug) plans for people who stay with Original Medicare. Montana has 11 stand-alone Part D plans for 2026, sold statewide, and anyone in Gallatin County with Original Medicare can join one of them. Check the 2027 Landscape on Medicare.gov to see the current picture.

For local shoppers, that typically means your drug coverage decision is tied to your medical coverage decision. If you want drug coverage bundled in, you'll likely be looking at a Medicare Advantage plan that includes Part D (an "MA-PD"). If you prefer Original Medicare, it's worth calling 1-800-MEDICARE or your local SHIP counselor to confirm what Part D options apply to your address before you enroll.

How to narrow 15 choices down to one

With more than a dozen Advantage plans on the table, a simple sorting process helps:

1. Start with your doctors and the hospital you use. Bozeman Health and other local providers may be in-network for some plans and not others. Check each plan's provider directory, or ask the clinic directly. 2. Then look at your prescriptions. Enter your drugs into the Plan Finder at medicare.gov to see how each plan covers them. 3. Then consider the total picture — premium, deductible, out-of-pocket maximum, and any extras you'd actually use. 4. Finally, look at Star Ratings as a general quality signal. CMS rates contracts on a 1-to-5 scale. Under CMS's 2026 Star Ratings, 2 of the 5 Medicare Advantage contracts offering plans in Gallatin County are rated 4 stars or higher, so ratings are one input alongside the fit with your doctors and drugs.
