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.
Idaho HMO plans rank 36th of 49 on star rating.
Across the 46 rated plans here the average overall rating is 3.63 stars, 36th highest of the 49 states with HMO plans. Ratings apply to the contract, so every plan a carrier files under one contract shares the same score.

Common questions
Idaho Medicare Advantage HMO plans, answered
How much do Medicare Advantage HMO plans cost in Idaho?
Of the Idaho HMO plans with a published premium, 67% 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 $7,305 across these plans.
What are the star ratings for Idaho HMO plans?
The 46 rated HMO plans in Idaho average 3.63 out of 5 stars, with 17 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 Idaho?
There are 49 HMO plans from 8 carriers, sold across 44 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. 9 of them are Special Needs Plans with extra eligibility rules (see below).
Do Idaho HMO plans include prescription drug coverage?
49 of the 49 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 Idaho?
9 of the 49 HMO plans in Idaho 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.
A $0 premium is not the whole cost.
