Topeka Medicare: comparing Medigap and Advantage plans

TOPEKA, Kan. — If you're turning 65 in Topeka or helping a parent sort out coverage, one of the first big decisions you'll face is how to receive your Medicare benefits. It usually comes down to two paths: Original Medicare paired with a Medigap (Medisupp) policy, or a Medicare Advantage plan. They're built very differently, and the structure — not the marketing — is what matters most for how you'll use your coverage.

The two structures, side by side

Original Medicare is the traditional federal program. It has two parts: Part A (hospital) and Part B (doctor and outpatient). You can add a stand-alone Part D drug plan, and you can add a Medigap policy — sold by private insurers — to help pay the deductibles and coinsurance Original Medicare leaves behind.

Medicare Advantage (Part C) is different. It's a private plan, approved by Medicare, that replaces the way you receive your Part A and Part B benefits. Most Advantage plans also include Part D drug coverage and sometimes extras like dental or vision. In exchange, you usually agree to use the plan's network of doctors and hospitals and follow its rules for referrals or prior authorization.

How you see doctors

This is often the biggest practical difference. Original Medicare lets you see any provider in the country that accepts Medicare — no network, no referrals. That matters if you split time between Topeka and family in another state, or if you want to keep the option of traveling to specialists at larger medical centers.

Medicare Advantage plans work more like employer insurance. They have networks, service areas, and often require you to pick a primary care doctor or get approval before certain services. For someone whose doctors are all in-network locally, that structure can work well. For someone who travels or wants maximum flexibility, Original Medicare plus Medigap tends to fit better.

How the costs are structured

With Original Medicare alone, there's no annual cap on what you might pay out of pocket for Part A and Part B services. That's why many people add a Medigap policy — it fills in those cost-sharing gaps in a predictable way. You pay a monthly premium for the Medigap plan on top of your Part B premium, and in return you get very predictable bills.

Medicare Advantage plans work the opposite way. Premiums are often lower (sometimes nothing beyond your Part B premium), but you pay copays or coinsurance as you use services, up to an annual out-of-pocket maximum set by the plan.

Drug coverage has its own rules. Every Part D plan — whether stand-alone or built into an Advantage plan — caps your out-of-pocket drug spending and limits the deductible each year. The cap is $2,100 in 2026 and $2,400 in 2027; the maximum deductible is $615 in 2026 and $700 in 2027. The old "donut hole" coverage gap was eliminated in 2025, so Part D now has three phases instead of four. If monthly drug costs are hard to budget for, the Medicare Prescription Payment Plan lets you spread them across the year.

The Medigap timing rule people miss

Here's a structural detail worth knowing before you choose. When you first enroll in Part B at 65, you get a one-time, six-month Medigap Open Enrollment Period. During that window, insurers must sell you any Medigap policy they offer at their standard rate, regardless of your health.

Once that window closes, in most states — Kansas included — insurers can use medical underwriting if you later try to switch from Medicare Advantage to Original Medicare with a Medigap plan. That means your health history could affect whether you qualify or what you pay. It doesn't mean you can't switch, but the door isn't always as wide open later as it is at 65.

What Topeka residents can compare

Topeka is in Shawnee County, where Medicare plan availability is set at the county level by CMS. The number of Medicare Advantage plans, stand-alone Part D drug plans, and Medigap options available to a Shawnee County resident is published each year and can be compared on the Medicare Plan Finder at Medicare.gov.

If you'd rather talk to someone, Kansas has a free State Health Insurance Assistance Program (SHIP) called Senior Health Insurance Counseling for Kansas (SHICK). SHICK counselors don't sell plans and don't earn commissions — they help you understand your options.

When you can make changes

Two dates to keep on the calendar:

• Annual Enrollment Period: October 15 – December 7. You can join, switch, or drop a Medicare Advantage or Part D plan, with coverage starting January 1.
• Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in an Advantage plan, you get one chance to switch to a different Advantage plan or return to Original Medicare (and add a Part D plan).

One more thing to keep in mind if you have higher income: IRMAA surcharges on Part B and Part D premiums kick in above $109,000 for a single filer in 2026, based on your tax return from two years earlier.
