Best Medicare Advantage plan for the lowest cost in a bad year in Nantucket County, Massachusetts

Why this plan

Mass General Brigham Advantage Signature (PPO) costs $3,900 a year in premiums and files no cost sharing at all for in-network medical care (a $0 out-of-pocket limit), so $3,900 is the most a year of covered care can cost you: the lowest worst case of the 4 plans open to everyone here. The next is Mass General Brigham Advantage Secure (HMO-POS), at $4,094 a year at most ($744 in premiums plus a $3,350 limit).

A $0 out-of-pocket limit is rare: before you rely on it, check the plan's Evidence of Coverage, which is the final word on what you pay.

The middle plan's worst year here is $4,522: in a year with a hospital stay or a run of treatment, this plan could cost you up to $622 less.

What it gives up

• Its premium, $325 a month, is higher than most plans here; the middle plan charges $106 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.
