Best Medicare Advantage plan for a low monthly premium in Ada County, Idaho

Why this plan

5 of the 13 plans open to everyone here charge no monthly premium, the lowest premium on offer. Among those 5, Humana Gold Plus H2486-005 (HMO) comes first: it has the lowest out-of-pocket limit for in-network care, $6,520.

What it gives up

Nothing we can measure: its premium and out-of-pocket limit are no higher than most plans' here, and its star rating isn't below average.

Who it suits

A low premium suits you if you're in good health and expect few doctor visits. The premium is the one cost you pay every month whether you use care or not. What you pay when you do use care -- copays, and in a bad year the out-of-pocket limit -- is the other half of the cost, and a $0 premium says nothing about it. You keep paying your Part B premium either way.

The next best for a low monthly premium

Before you choose

• Check your doctors and hospitals. Most Medicare Advantage plans pay only, or mostly, for care in their own network. Ask the plan, or your doctor's office, before you join.
• Price your prescriptions. What your drugs cost can differ by hundreds of dollars a year between plans and outweigh any premium difference. Add them in our plan list to see your own costs.
• Read the plan's own documents. We take every figure from what the plan filed with Medicare, but its Evidence of Coverage is the final word on what it pays.
• Get free advice if you want it. Your State Health Insurance Assistance Program (SHIP) gives free, unbiased help choosing a plan.

How we picked

The plan with the lowest monthly premium. Where several tie, we look next at the largest Part B giveback, then the lowest out-of-pocket limit for in-network care, then the lowest copay to see a primary care doctor. Plans that still tie are listed by name.
