Wisconsin
Medicare and retirement planning in Winnebago County
Winnebago County sits on both sides of Lake Winnebago's western shore and covers two distinct markets — Oshkosh in the south and the Neenah–Menasha area in the north. About 71% of beneficiaries here are in Advantage plans.
What's different here
The local picture
The county's split geography matters more than it looks. Plan networks that work well in Neenah are oriented toward the Fox Cities; Oshkosh residents sometimes travel a different direction for specialty care. It is worth confirming which system a plan actually contracts with before enrolling.
Because Wisconsin is a Medigap waiver state, a quote you find on a national website is often for a plan that is not sold here at all. The comparison that matters in Wisconsin is which riders you add to the basic policy — not which letter you pick.

How neighbours are covered
Winnebago County coverage mix
This is not a recommendation — plenty of people are in the minority column for very good reasons. It is context for the conversation.
| Category | Value |
|---|---|
| Medicare Advantage | 26,632 (71.1%) |
| Original Medicare | 10,849 (28.9%) |
| Standalone Part D | 7,650 |
| Drug coverage via Advantage | 24,801 |
| Also on Medicaid | 4,649 |
Categories overlap on purpose — someone in an Advantage plan with drug coverage appears in both the Advantage row and the drug-coverage row.

Questions
Winnebago County questions
Which Medicare plans are available in Winnebago County?
Plan availability is set at the county level, so Winnebago County residents shop the Winnebago County plan menu. That menu changes every year, and we do not offer every plan available in the area — for a complete list, contact Medicare.gov, call 1-800-MEDICARE, or reach your State Health Insurance Assistance Program.
How many people in Winnebago County are on Medicare?
About 37,481 as of the CY2025 CMS enrollment data — 26,632 of them (71.1%) in Medicare Advantage plans and 10,849 (28.9%) on Original Medicare.
Do you charge for a review in Winnebago County?
No. There is no fee to review your coverage or compare options. Agent compensation is paid by the insurance carrier when a policy is placed, and it does not change what you pay in premium.
When can I change my Medicare plan?
Medicare Advantage and Part D changes are made during Annual Enrollment — October 15, 2026 through December 7, 2026, effective January 1, 2027. Certain life events, including moving out of your plan's service area or qualifying for Extra Help, can open a Special Enrollment Period at other times of year.
Do you meet in person in Winnebago County?
We are remote-first, so nearly every review — including in Winnebago County — happens by phone or video. In-person appointments are reserved for people who genuinely need one, in our northeast Wisconsin home area, and are assessed case by case when you book. Call (920) 455-5547 or book a time online and we will sort out the format.
Enrollment and population figures on this page describe the local market. They are not a statement about which plan is right for you, and they are not a quote. Plan availability, benefits and premiums vary by county, carrier and individual eligibility, and change every plan year.
