Best Medicare Advantage plan for the lowest cost in a bad year in Marion County, Oregon

Why this plan

Kaiser Permanente Senior Advantage Enhanced (HMO-POS) costs $1,428 a year in premiums and caps what you pay for in-network medical care at $3,500, so $4,928 is the most a year of covered care can cost you: the lowest worst case of the 20 plans we compare here. The next is Kaiser Permanente Senior Advantage Standard (HMO-POS), at $4,944 a year at most ($444 in premiums plus a $4,500 limit).

The middle plan's worst year here is $6,974: in a year with a hospital stay or a run of treatment, this plan could cost you up to $2,046 less.

ATRIO Prime Rx (HMO) would come first on this alone, but Medicare rates it 2.5 stars, below the 3 stars we require for a pick.

What it gives up

• Its premium, $119 a month, is higher than most plans here; the middle plan charges $36 a month.

Who it suits

This suits you if you have an ongoing condition, a surgery or treatment coming, or simply want to know the worst a year can cost. Once your copays and coinsurance for in-network medical care reach the plan's out-of-pocket limit, it pays in full for covered care for the rest of the year -- but you keep paying the premium, so we count both.

The next best for the lowest cost in a bad year

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 whose worst year costs least: twelve months of premiums plus its yearly limit on what you pay for covered medical care in its network. Drugs aren't included; Part D has its own yearly cap. Where several tie, we look next at the largest Part B giveback, then the lowest premium, then the lowest copay to see a primary care doctor. Plans that still tie are listed by name.

We compare the 22 Medicare Advantage plans with drug coverage that anyone with Medicare in Marion County can join. Special needs plans and PACE, which are only for people who qualify, aren't included; you'll find them on the Marion County page. No plan pays to be picked.

We don't pick plans Medicare rates below 3 stars, and leave 2 out here: ATRIO Choice Rx (PPO) (2 stars), ATRIO Prime Rx (HMO) (2.5 stars). Plans too new to have a rating are included, and say so.
