Medicare Plans
Medicare Advantage vs. Medicare Supplement in Overland Park, KS
Most Overland Park retirees end up choosing between the same two roads: a Medicare Advantage plan that bundles everything into one low-premium private plan, or a Medicare Supplement, also called Medigap, that sits behind Original Medicare and pays what Medicare leaves unpaid.
There's no universal right answer. It comes down to your doctors, your prescriptions, whether you see doctors on the Missouri side of the metro, and how much monthly cost you're willing to trade for predictability.
- Two different ways to cover the gaps in Original Medicare
- Which hospitals are in network is usually the deciding factor
- The premium is only half of what a plan costs you

Local networks
What this looks like at Kansas City area hospitals
-
Medigap: no network to worry about
If a doctor accepts Original Medicare, your Medigap plan goes with you. That covers Johnson County hospitals, Missouri doctors such as those at Saint Luke's Plaza, and specialists anywhere in the country, no referrals needed. -
Advantage: the network is the plan
Johnson County Advantage plans vary on which hospital systems they contract with: HCA Midwest, Saint Luke's, AdventHealth or The University of Kansas Health System. Some reach Missouri doctors and some do not. Networks can change every January. -
Drug coverage works differently
Advantage plans usually fold Part D right in. With Medigap you buy a standalone Part D plan and can shop it separately every fall, often the cheaper route if you're on an expensive drug.
Across Johnson County, the network question usually comes down to four systems: HCA Midwest Health (Overland Park Regional and Menorah), Saint Luke's (Saint Luke's South), AdventHealth (South Overland Park, Shawnee Mission and Lenexa City Center) and The University of Kansas Health System (Indian Creek Campus, the KU Cancer Center in Overland Park and Olathe Hospital). Anyone in cancer treatment should check The University of Kansas Cancer Center by name. Medicare plans are sold by county, so your Kansas plan list differs from the Jackson County, Missouri list, and a Kansas Advantage network may not include your Missouri doctors. Veterans who get care at the Kansas City VA Medical Center or the Overland Park VA Clinic can use VA benefits alongside either path, but the VA does not bill Medicare, so think about where you'll get care outside the VA.

Choose Advantage if
When a Medicare Advantage plan makes sense
- You want the lowest monthly premium, often $0 beyond Part B
- Your doctors and preferred hospital already sit inside the plan's network
- Extras like dental, vision, hearing and a gym membership matter to you
- You're fine with copays as you use care, backed by an annual out-of-pocket cap
- You get routine care from one health system, on one side of the state line
Choose Medigap if
When a Medicare Supplement makes sense
- You'd rather pay one predictable premium than copays at every visit
- You see several specialists, or see doctors in both Kansas and Missouri
- You want to keep any doctor who accepts Medicare, with no referrals required
- You have ongoing treatment where per-visit copays would pile up quickly
- You're inside your 6-month Medigap open enrollment window and can sign up without health questions
The timing detail people trip over
You can join or change an Advantage plan each fall during Open Enrollment. Moving back to a Medigap plan later usually means answering health questions, and the insurer can decline you. Keep that one-way street in mind before you make your first choice.
Total cost
Compare the whole year, not the premium
A $0-premium Advantage plan isn't free. Add up realistic copays for your regular doctor visits, specialists, imaging and any planned procedure, then stack that total against a year of Medigap premiums plus a standalone drug plan. For a healthy 66-year-old in Leawood or Lenexa, the Advantage math often wins. For someone managing a chronic condition with frequent specialist visits, Medigap often costs less across twelve months.
We run that math using your own drug list and doctors. Start with the Medicare checklist, or read the mistakes to avoid before you sign anything. For free, unbiased counseling on every plan in your county, SHICK (Senior Health Insurance Counseling for Kansas) is at 1-800-860-5260.
