Duluth has something most of Minnesota lost in 2019: Medicare Cost plans. Add Essentia and Aspirus St. Luke’s, and the comparison here looks different from the metro.
What to know before you compare plans in St. Louis County
St. Louis County is one of 21 Minnesota counties where Medicare Cost plans are still sold, so Duluth residents can choose a plan that uses a local network at home and Original Medicare everywhere else — a fit for winters in Arizona or a Mayo referral. That option sits alongside Medicare Advantage and Original Medicare with a Minnesota supplement.
Duluth’s two systems, Essentia Health and Aspirus St. Luke’s, contract differently with each plan, and HealthPartners left Medicare Advantage in St. Louis County for 2026. We start by confirming your doctors and hospital are covered, then compare premiums.

When you can enroll

Your options
Which kind of plan fits you in Duluth?
Medicare Advantage
All-in-one Part C plans, often $0 premium, that use a local network — so your providers and prescriptions matter.
Yes. St. Louis County is one of the 21 Minnesota counties where Cost plans are still offered, sold by Blue Cross Blue Shield of Minnesota and Medica. Premiums and availability are published each year by the Minnesota Department of Commerce, and we compare them against Advantage and supplement options.
Which plans include Essentia and Aspirus St. Luke’s?
Each system contracts with some plans and not others, and the lists change every October. Original Medicare with a supplement covers both without a network. We confirm your doctors against the plan directory before you enroll.
How much does your help cost?
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
