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.

Good to know

Medigap in Richfield: questions (2027)

What is a Medigap plan, and how does it work in Richfield?
A Medigap plan, also called Medicare Supplement Insurance, is a private insurance policy that helps pay the deductibles, coinsurance and copayments Original Medicare (Part A and Part B) leaves behind. Medigap policies are sold statewide, so people in Richfield can buy any policy an insurer sells in Minnesota.
When can I buy a Medigap policy in Richfield?
Your Medigap Open Enrollment Period is the 6 months that start the first month you are 65 or older and enrolled in Part B. During it, an insurer cannot refuse to sell you any Medigap policy it offers or charge you more because of your health. After it, insurers can use medical underwriting unless you have a guaranteed-issue right; some states add more rights, so check with the state insurance department. Medigap is not tied to the fall Annual Enrollment Period.
What is the difference between Medicare Advantage and Medicare Supplement in Richfield?
Medicare Advantage is a private plan that replaces how you get Part A and Part B, usually with a provider network and Part D drug coverage built in. A Medicare Supplement (Medigap) policy keeps Original Medicare and helps pay the deductibles and coinsurance it leaves behind; it has no network beyond doctors who take Medicare and does not include drug coverage, so most people add a Part D plan. You cannot use a Medigap policy to pay costs in a Medicare Advantage plan.
What does Medicare cost in Richfield for 2027?
Program-level costs are the same everywhere: the standard Part B premium is $202.90/month for 2026 (2026 amount; 2027 figure will be posted when CMS releases it), and Part D drug costs are capped at $2,400 out of pocket for the year in 2027. What an individual plan charges varies by plan; we don't publish those figures or rank plans.

Here's the Richfield picture in plain terms. Your county sets your Medicare options, and Richfield sits in Hennepin County (part of Richfield area) — so that's the lens for everything below.

25 Medicare Advantage plans are available for 2027. Roughly 57% of people with Medicare in the county have chosen Medicare Advantage over Original Medicare, among the roughly 198,051 residents who are 65 or older. Those are factual, area-level counts — we don't rank plans.

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 Richfield, 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 Richfield, Minnesota. It's a framework, not a ranking — and we don't quote premiums.

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.
