Medicare Supplement (Medigap) chart
Medigap plans in Minnesota are different (2027)
Minnesota is one of three states (with Massachusetts and Wisconsin) that do not use the federal Medigap letters A through N. Minnesota standardizes its own Medigap plans (Basic and Extended Basic, with optional riders, plus Minnesota versions of Plans K, L, M, N and high-deductible plans) instead of the federal A-N letters; compare policies by those names.
For ZIP code 55401, the Medicare.gov Medigap policy search listed these Minnesota plan types for 2026: Basic, Extended Basic, High Deductible, High Deductible (new), 50% Cost-Sharing, 75% Cost-Sharing, Extended Basic (new), Minnesota N.
The federal Medigap comparison chart used in the other 47 states and DC does not apply in Minnesota. For the benefits of each Minnesota plan, see the Minnesota insurance department’s Medigap guide or the Medigap policy search on Medicare.gov, or call 1-800-MEDICARE.

New to Medicare around St. Paul? Start with one fact that clears up a lot of confusion: what's available to you is decided at the county level, and St. Paul falls in Ramsey County (part of St. Paul area).
There, 27 Medicare Advantage plans are available for 2027. About 60% of the county's Medicare members are in a Medicare Advantage plan rather than Original Medicare, among the roughly 85,596 residents who are 65 or older.
Below, we lay out the carriers serving the area, how Original Medicare, Advantage, Medigap and Part D relate, the 2027 numbers everyone shares, the enrollment calendar, and free help — all educational, with no plan rankings.
Ramsey County at a glance
St. Paul is in Ramsey County. Medigap plans are standardized by letter everywhere, so the local question is how many neighbors use them and what the alternatives look like. Ramsey County's figures, from CMS:

| Share in Medicare Advantage instead | 60% |
What Medigap does — and doesn't — cover
Think of Medigap as the layer that sits on top of Original Medicare to absorb the costs it leaves you: the deductibles, the 20% coinsurance, the copays that otherwise have no annual ceiling.
The catch that trips people up is that these plans are federally standardized — a Plan G from one insurer covers exactly what a Plan G from another does. So the letter defines the benefits, and price and service are what separate companies. Medigap doesn't include drug coverage, so most people in St. Paul, Minnesota pair it with a stand-alone Part D plan.
Below we break down what each standardized plan covers and the enrollment rights that matter most in St. Paul, Minnesota. It's a framework, not a ranking — and we don't quote premiums.

How people get Medicare in Ramsey County
(MA penetration in Ramsey County)
MA penetration from CMS enrollment data; Medigap share is an estimate. U.S. average is about 54% Medicare Advantage. These are area-level figures, not plan-specific.
What Medicare costs in 2027
It helps to separate the costs everyone shares from the costs that vary by plan. The program-level numbers here are set nationally — the same whether you're in a big city or a rural county.
Part B premium. Most people pay the standard Part B premium of $202.90 a month in 2026 (2026 amount; 2027 figure will be posted when CMS releases it). Part A is premium-free for most people who worked and paid Medicare taxes long enough.
Part D drug costs. In 2027, a Part D plan's yearly deductible can be no more than $700, and a $2,400 cap limits what you pay out of pocket for covered prescriptions across the year — a real change for anyone with high drug costs.
Higher earners pay more for Parts B and D through an income-related adjustment called IRMAA, which for 2026 starts above $109,000 in annual income for an individual and is based on your 2024 tax return. Most people fall below that line and pay the standard amounts. The 2027 brackets will be posted when CMS releases them.
Plan-specific costs. What an individual plan charges — its premium, deductible, copays, and what it covers — varies by plan and changes yearly. We don't publish those figures or rank plans; Medicare's Plan Finder shows the current details for your situation, and a licensed agent can walk you through them.
By the numbers
Medicare Part B premium, 2006–2026
The standard monthly Part B premium has climbed from $88.50 in 2006 to $202.90 in 2026. Hover any point for that year’s premium.

Your Medicare enrollment calendar
The dates that follow are set federally, so they don't change from state to state — only your personal timing does.
It starts with your Initial Enrollment Period — the 7-month window around your 65th birthday month — the window around turning 65 when you first sign up. Missing it can mean late penalties that stick around, so it's the one not to sleep on.
After that, the big recurring window is the Annual Enrollment Period, October 15 – December 7, when anyone can join, switch, or drop an Advantage or Part D plan for a January 1 start. And if you're already in an Advantage plan, the Medicare Advantage Open Enrollment (January 1 – March 31) gives you one more chance to change course.
Life events — a move, a loss of other coverage — can also trigger a Special Enrollment Period. The calendar below shows the whole year at a glance.
