Medicare Advantage Plans in La Crosse, WI (2026)
Medicare Advantage (Part C) is a private alternative to Original Medicare — bundling hospital, medical, and usually drug coverage into one plan. For 2026, La Crosse County has 22 plans from 6 carriers, including 9 $0-premium options. But the right plan isn't the cheapest premium — it's the one whose network includes your doctors, whose formulary covers your drugs, and whose out-of-pocket limits fit your health usage.
How Medicare Advantage works — and why it matters in La Crosse
When you enroll in a Medicare Advantage plan, you don't leave Medicare — you stay enrolled in Parts A and B and continue paying your Part B premium ($202.90/month in 2026). What changes is how your coverage is delivered: instead of Original Medicare paying claims directly, a CMS-approved private insurer steps in and provides at least everything Original Medicare covers, often with extras and a different cost structure.
What's bundled in
- Hospital (Part A) coverage
- Medical (Part B) coverage
- Prescription drugs (Part D) — most plans
- Dental, vision, hearing — many plans
- OTC allowances, fitness benefits — some plans
Key trade-offs to understand
- Provider networks — not all doctors accepted
- Referrals required on HMO plans
- Prior authorization for some services
- Plan terms can change each January 1
- Switching back to Medigap later may require underwriting
Why La Crosse is different
- Two major health systems competing for your care: Gundersen and Mayo Clinic Health System
- Not every plan covers both — network verification is essential
- Regional carriers (Quartz/BCBS WI) built specifically for WI markets
- Rural-adjacent geography means PPO flexibility matters for some residents
Verifying your Gundersen and Mayo network status before enrolling
La Crosse County is served by two major health systems — Gundersen Health System (headquartered in La Crosse) and Mayo Clinic Health System (with campuses in La Crosse and Onalaska). Both are rated 4 stars by CMS Hospital Compare. But Medicare Advantage plan coverage of each system varies — and networks change every January 1.
Make a list of your primary care doctor, any specialists you see regularly, and the hospital you prefer for non-emergency procedures. Include the practice name and the address — not just the system name. A physician can be employed by Gundersen Health System but their specific clinic location may not be included in every plan's network.
Every Medicare Advantage plan maintains an online provider directory at Medicare.gov's Plan Finder or on the carrier's website. Search for each provider by name and address. If a name appears but the address doesn't match your clinic, that provider may not be in-network at the location you use. When in doubt, call the plan's member services line and ask them to confirm: "Is [Provider Name] at [Specific Address] in-network for plan year 2026?"
Even if your doctor is in-network, the hospital they use for procedures or admissions must also be in-network for you to receive in-network cost-sharing. Gundersen La Crosse Hospital and Mayo Clinic Health System in La Crosse and Onalaska are each highly rated facilities — but if your plan only includes one system, an admission to the other could expose you to out-of-network costs or the plan's full out-of-pocket maximum.
On an HMO plan, going out-of-network (except for emergencies) typically means the plan pays nothing — you pay full cost. On a PPO plan, you can see out-of-network providers at a higher cost-sharing tier. If you value access to both Gundersen and Mayo regardless of which plan you're on, a PPO gives you a safety net. We compare HMO and PPO options side by side for each client's specific situation.
A plan that covered your Gundersen physician in 2025 may not cover the same physician in 2026. Each fall, during Annual Enrollment Period (Oct 15–Dec 7), re-verify your entire provider list against every plan you're considering — even if you're staying on your current plan. We do this for every client we serve as part of our annual review.

How Medicare Advantage star ratings work — and why they matter
CMS rates every Medicare Advantage plan on a 1-to-5 star scale each fall, published annually. The ratings are based on up to 45 measures across 9 quality domains. Star ratings aren't just a quality label — they have real financial and enrollment consequences.
What CMS measures

Why star ratings matter to you
Bonus payments → better benefits
Plans rated 4+ stars receive Quality Bonus Payments from CMS. Plans use these bonuses to fund richer benefits — lower copays, more dental allowance, better drug coverage — without raising premiums. A 4-star plan often delivers more value than a 3.5-star plan at the same $0 premium.
Indicator of plan stability
Plans with consistently low star ratings are more likely to reduce benefits, raise costs, or exit the market. A plan rated below 3 stars for three consecutive years can be terminated by CMS. Choosing a well-rated plan reduces your risk of disruptive mid-term changes.
5-star SEP: an extra enrollment window
If a 5-star plan is available in your county, you can switch to it once between December 8 and November 30 — completely outside the normal enrollment windows. This gives beneficiaries with quality concerns an escape valve mid-year. Currently, no La Crosse County plan holds a 5-star rating (local maximum: 4 stars), so this SEP is not available locally for 2026.
What Medicare Advantage actually costs — a real walkthrough
The $0 premium headline is real, but it's only one piece of your total cost. Here's how the three cost layers work together.
Your monthly premium
You always pay the standard Medicare Part B premium ($202.90/month in 2026) to the federal government regardless of which plan you choose. Many local plans charge $0 on top of that — meaning your only fixed monthly cost is your Part B premium. Some plans with richer benefits (like broader PPO networks or lower copays) charge an additional monthly premium of $49–$79/month locally.
Copays and coinsurance when you use care
Each time you see a doctor, fill a prescription, or have a procedure, you owe your share of the cost. These vary significantly by plan and by tier. Common structure: primary care visits $0–$20 copay, specialist visits $30–$50 copay, urgent care $50–$90 copay, inpatient hospital stay $250–$400/day for the first several days. Drug costs depend on the tier your medication is on and whether your pharmacy is preferred.
Annual out-of-pocket maximum (MOOP)
Every Medicare Advantage plan must cap your annual in-network out-of-pocket spending. The 2026 mandatory maximum is $9,250 for in-network costs (down from $9,350 in 2025), or $13,900 combined in-network and out-of-network — the $9,250 in-network cap is cross-verified against CMS's CY2026 MA/Part D Landscape File, where thousands of approved plans nationwide are capped at exactly $9,250 and none exceed it. Once you hit your plan's MOOP, the plan pays 100% of covered in-network costs for the rest of the year. This is the key protection Advantage offers that Original Medicare alone does not. Plans set their own MOOP below the statutory cap — some plans locally set it lower.
The real comparison: Total annual cost = (monthly premium × 12) + expected copays + drug costs. A $0-premium plan that you use heavily can cost more than a $49/month plan with lower cost-sharing. We model your realistic annual cost across every available plan based on your health usage and drug list — not just the premium line.
When you can enroll in or change Medicare Advantage
Missing an enrollment window can mean being stuck in the wrong plan for a year, or triggering a penalty. Here are all the windows that apply in 2026.
| Period | Dates | Who can use it | What you can do |
|---|---|---|---|
| Annual Enrollment Period (AEP) | Oct 15 – Dec 7 | All Medicare beneficiaries | Switch between any Medicare Advantage plans, switch between MA and Original Medicare, change Part D plans. Changes take effect January 1. |
| Medicare Advantage Open Enrollment Period (MA-OEP) | Jan 1 – Mar 31 | Current MA enrollees only | Switch to a different MA plan or return to Original Medicare — once. Cannot use to switch from Original Medicare to MA. |
| Initial Enrollment Period (IEP) | 7-month window around your 65th birthday | People turning 65 (or newly entitled to Medicare) | Enroll in Medicare Parts A, B, C, and D for the first time. Missing this without creditable coverage triggers permanent penalties. |
| 5-Star Special Enrollment Period | Dec 8 – Nov 30 (ongoing) | Any Medicare beneficiary | Switch to a Medicare Advantage plan with a CMS 5-star rating — once per year. Available only where a 5-star plan exists. No 5-star plans currently in La Crosse County. |
| Special Enrollment Periods (SEPs) | Varies by trigger event | Beneficiaries who experience qualifying life events | Moving to a new service area, plan exits your county, losing other coverage, qualifying for Medicaid, or other CMS-defined events. Typically a 60-day window from the event. |

Medicare Advantage questions, answered
Can I switch Medicare Advantage plans mid-year?
Generally no — outside of special circumstances you are locked into your plan until the next Annual Enrollment Period (Oct 15–Dec 7). However, you do have a Medicare Advantage Open Enrollment Period from January 1 through March 31 each year, during which you can switch to a different Medicare Advantage plan or return to Original Medicare once. Life events like moving, losing other coverage, or your plan leaving your area can also trigger a Special Enrollment Period.
Can I drop Medicare Advantage and go back to Original Medicare?
Yes — during the Medicare Advantage Open Enrollment Period (January 1 – March 31) you can disenroll from your Advantage plan and return to Original Medicare once. After returning, you may want to add a Wisconsin Medicare Supplement (Medigap) policy and a Part D drug plan. Important: Wisconsin Medigap carriers can require health underwriting after your initial guaranteed-issue window closes, so switching back later in life may be harder if you have health conditions. This is one reason the track you choose at 65 matters so much.
What happens if my doctor leaves the plan's network mid-year?
If your provider leaves a Medicare Advantage network during the plan year, your plan must generally give you at least 90 days notice and help transition your care. In some cases — particularly if the provider leaving was your primary care physician or a specialist treating an ongoing condition — you may qualify for a Special Enrollment Period to switch plans. Contact your plan and ask whether you qualify for an SEP before your 90-day transition window closes.
What is prior authorization and how does it affect Medicare Advantage?
Prior authorization (PA) is a plan requirement that your doctor get approval from the plan before you receive certain services, procedures, or medications. Medicare Advantage plans can require PA for things Original Medicare doesn't — including specialist visits, imaging, surgeries, and some drugs. CMS has strengthened prior authorization rules in recent years, requiring MA plans to approve, deny, or request more information within 72 hours for urgent requests and 7 days for standard requests. Always verify whether a service requires PA before scheduling it, especially for anything costly. We can help you understand your specific plan's PA requirements.
What if my drugs change on the formulary next year?
Medicare Advantage plans that include Part D drug coverage (MA-PD plans) can change their formularies — the list of covered drugs — each year. Plans are required to send you an Annual Notice of Change (ANOC) by September 30 each year listing any changes to your coverage, costs, or network effective January 1. If your drugs are moving to a higher cost tier, being removed, or if your pharmacy is leaving the preferred network, this is your cue to shop plans during AEP (Oct 15–Dec 7). We run your drug list against every available plan formulary each fall at no charge.
Are Gundersen Health System and Mayo Clinic Health System covered by Medicare Advantage plans in La Crosse?
Many — but not all — plans in La Crosse County include Gundersen and/or Mayo providers. Plan networks change every January 1, so you must verify coverage for your specific physicians and facilities before enrolling, even if you were covered in a prior year. Quartz (a local Wisconsin insurer) explicitly markets Gundersen and Mayo network access. We check your specific doctors and facilities against every available plan before you enroll.
Is a $0-premium Medicare Advantage plan really free?
No. A $0-premium plan means you pay no extra monthly premium beyond the standard Part B premium ($202.90/month in 2026) — but you still owe your Part B premium to Medicare. You will also pay copays and coinsurance when you use services, a possible drug deductible, and you remain exposed up to the plan's annual out-of-pocket maximum. Two $0-premium plans can differ by thousands of dollars in real annual cost depending on how much care you use.
What is the five-star Special Enrollment Period?
CMS rates Medicare Advantage plans on a 1–5 star quality scale annually. If a 5-star plan is available in your service area, you can switch to it once between December 8 of the prior year and November 30 of the current plan year — outside of any other enrollment window. For 2026, this SEP runs December 8, 2025 through November 30, 2026. No plan in La Crosse County currently holds a 5-star rating (the local maximum is 4.0 stars), so this SEP is not available locally right now.
