How Medicare Coverage Structures Differ in Milwaukee

MILWAUKEE — Choosing how to get your Medicare coverage is one of the most important decisions a new enrollee makes, and it usually comes down to two very different structures: Original Medicare paired with a Medigap policy, or a Medicare Advantage plan. Both are legitimate paths built into the Medicare program, but they work in almost opposite ways — and understanding that difference now can save a lot of confusion later.

With the Annual Enrollment Period running Oct. 15 through Dec. 7, Milwaukee residents have a natural window to sit down and think this through before 2027 coverage begins.

Two different structures, same underlying program

Original Medicare is the traditional, federally run program. It has two parts: Part A (hospital) and Part B (doctor and outpatient). You can see any doctor or hospital in the country that accepts Medicare, and there is no network. But Original Medicare alone does not cap what you pay out of pocket, and it does not include prescription drug coverage.

That is where two add-ons come in. A Medigap (Medicare Supplement) policy, sold by a private insurer, helps pay the deductibles and coinsurance Original Medicare leaves behind. And a standalone Part D plan covers prescriptions.

Medicare Advantage (Part C) takes a different approach. It is offered by private insurers approved by Medicare, and it bundles Part A, Part B, and usually Part D into one plan. Advantage plans generally use provider networks (HMO or PPO), require referrals or prior authorization for some services, and set their own copay structures. They must include an annual out-of-pocket maximum for Part A and B services.

What that means day to day

With Original Medicare + Medigap, you carry more monthly cost (a Part B premium, a Medigap premium, and a Part D premium), but your costs at the point of care are highly predictable. Travel is easy — any Medicare provider, anywhere in the U.S., is in.

With Medicare Advantage, your monthly premium is often lower, but you pay copays as you use services, and you generally need to stay in-network. Many plans include extras Original Medicare does not cover, such as some dental, vision, or hearing benefits. The tradeoff is that the plan — not just Medicare — decides how care is managed.

Neither structure is "better." They serve different priorities.

Local availability in Milwaukee County

Milwaukee is in Milwaukee County, where Medicare beneficiaries typically have a wide range of Medicare Advantage plans and standalone Part D plans available from multiple carriers. Availability is set at the county level, so the specific plans offered to a Milwaukee resident are the same ones offered anywhere else in Milwaukee County. You can see the current-year list for your ZIP code using the Plan Finder at medicare.gov.

Having many options is helpful, but it also means comparing carefully. The number of choices is not a reason to rush.

What's the same in 2027 either way

Some Part D rules apply no matter which path you take:

• The Part D out-of-pocket cap is $2,100 in 2026. Once you hit it, you pay $0 for covered drugs the rest of the year.
• The Part D maximum deductible is $615.
• The old coverage gap ("donut hole") has been eliminated as of 2025 — Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan is available if you want to spread your drug costs across the year in monthly installments rather than paying at the pharmacy counter.
• IRMAA surcharges on Part B and Part D begin above $109,000 in income for a single filer in 2026.

Enrollment windows to know

• Annual Enrollment Period: Oct. 15 – Dec. 7. You can switch between Original Medicare and Medicare Advantage, change Part D plans, or join a plan for the first time. Changes take effect Jan. 1.
• Medicare Advantage Open Enrollment: Jan. 1 – March 31. If you are already in an Advantage plan, you get one chance to switch to a different Advantage plan or drop back to Original Medicare (and pick up a Part D plan).

One caution worth knowing before you decide: in most states, including Wisconsin, if you leave Medigap and later try to come back, insurers can use medical underwriting. That means moving from Medigap to Advantage is easier than moving from Advantage to Medigap. This is worth asking about before making a switch.
