A $0 plan premium is not a free plan. You still pay your Part B premium to Medicare, plus copays and coinsurance as you use care. Star ratings are published by CMS per contract, so every plan a carrier files under the same contract shares one rating — it describes the carrier’s performance, not this specific plan’s benefits. Estimate your real costs.

Montana has one of the smallest Medicare Advantage HMO markets in the country.

There are 7 HMO plans here from 3 insurers, against an average of about 89 per state. Fewer options makes the comparison quicker, but it also means one plan's network or drug list can decide the whole choice.

HMO plans in Montana rate below the national average.

The 7 rated HMO plans here average 3.50 stars against a national median of 3.82. No plan here reaches 4 stars, so the rating will not separate them for you — compare on network, drug coverage and out-of-pocket limits instead. The score describes the carrier's contract, not any one plan's benefits.

Common questions

Montana Medicare Advantage HMO plans, answered

How much do Medicare Advantage HMO plans cost in Montana?
Of the Montana HMO plans with a published premium, 75% charge $0 a month. A $0 premium does not mean the plan is free: you still pay your Part B premium to Medicare, plus copays and coinsurance as you use care. The number that actually caps a bad year is the in-network out-of-pocket maximum, which averages $7,775 across these plans.
What are the star ratings for Montana HMO plans?
The 7 rated HMO plans in Montana average 3.50 out of 5 stars, with 0 rating 4 or better. CMS rates a contract rather than an individual plan, so every plan a carrier files under the same contract shares one score. A contract that is too new or has too little data is not rated at all, which is different from rating badly.
How many Medicare Advantage HMO plans are available in Montana?
There are 7 HMO plans from 3 carriers, sold across 56 counties. Availability is set by county, so the plans you can actually join depend on where you live — the full list is rarely available in any one place. 1 of them are Special Needs Plans with extra eligibility rules (see below).
Do Montana HMO plans include prescription drug coverage?
7 of the 7 HMO plans here bundle Part D drug coverage into the plan. That is the usual arrangement for Medicare Advantage and there is no separate drug premium for it — the plan premium covers both. If you join a Medicare Advantage plan without drug coverage, you generally cannot add a standalone Part D plan alongside it.
What is a Special Needs Plan, and are there any in Montana?
1 of the 7 HMO plans in Montana are Special Needs Plans. SNPs limit enrollment to people who also have Medicaid, live in a nursing home or similar institution, or have a qualifying chronic condition. They often carry richer benefits for that group, but if you do not meet the criteria you cannot join one — so the real number of plans open to you may be lower than the total.
