The structural gap between Medigap and Medicare Advantage in Lexington

# Original Medicare with a Medigap plan vs. Medicare Advantage: how to think it…

LEXINGTON, Ky. — If you are turning 65 in the Bluegrass or helping a parent sort out coverage, one choice usually shapes everything else: stay with Original Medicare and add a Medigap policy, or move your benefits into a Medicare Advantage plan. They are built very differently, and understanding that structure up front makes the rest of the decision much easier.

Two different structures, not just two different prices

Original Medicare is the traditional federal program. Part A covers hospital stays, and Part B covers doctor visits and outpatient care. You can see any provider in the country who accepts Medicare, and there is no network. Because Original Medicare does not cap your out-of-pocket costs on its own, most people add a Medigap (Medicare Supplement) policy to help pay the deductibles and coinsurance Medicare leaves behind. Drug coverage is separate — you add a stand-alone Part D plan.

Medicare Advantage works differently. You still have Medicare, but a private insurance company manages your Part A and Part B benefits through a plan Medicare has approved. Most Advantage plans include Part D drug coverage and may include extras like dental or vision. In exchange, you generally use the plan's network of doctors and hospitals and follow its rules for referrals and prior authorization.

What each path looks like in real life

With Original Medicare plus Medigap and a Part D plan, you are usually juggling three cards: your red, white, and blue Medicare card, your Medigap card, and your Part D card. You get broad provider choice, predictable cost-sharing, and fewer network worries. The tradeoff is a monthly Medigap premium on top of your Part B premium.

With Medicare Advantage, you typically carry one plan card. Your costs and rules — copays, prior authorizations, in-network providers — are set by that plan. Costs can be lower month to month for some people, but you are working inside the plan's network, which matters if you travel often or split time between Lexington and another state.

What is the same no matter which you choose

Some pieces of Medicare are set by the federal government and do not change based on the path you take:

• Part D drug rules. The Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027, and the maximum Part D deductible is $615 in 2026 and $700 in 2027. The old "donut hole" coverage gap was eliminated in 2025, leaving three payment phases.
• The Medicare Prescription Payment Plan. This optional program lets you spread your drug costs across the year in monthly payments instead of paying big amounts at the pharmacy counter.
• IRMAA. Higher-income enrollees pay an income-related surcharge on Part B and Part D. For 2026, IRMAA begins above $109,000 in income for a single filer.
• Enrollment windows. The Annual Enrollment Period runs Oct. 15 – Dec. 7, and the Medicare Advantage Open Enrollment Period runs Jan. 1 – March 31.

A Lexington snapshot

Lexington is in Fayette County, and Medicare plan availability — both Medicare Advantage plans and stand-alone Part D plans — is set at the county level. That means two neighbors on the same street will see the same menu of plans, but a cousin in a nearby county may see a different list. When you compare options, use the Plan Finder at Medicare.gov and enter your ZIP code so you are looking at plans actually offered where you live.

Medigap works differently from Advantage. Medigap policies are standardized by letter (Plan G, Plan N, and so on), and in Kentucky, insurers set their own premiums for those standardized plans. Your best protection is your one-time Medigap Open Enrollment Period — the six months that begin when you are 65 and enrolled in Part B. During that window, insurers cannot turn you down or charge you more based on your health.

Questions worth asking yourself

• Do my current doctors and the hospital I trust take Original Medicare, or are they in a specific Advantage plan's network?
• How often do I travel, and would a national provider network matter?
• Am I comfortable managing separate cards and premiums, or do I want everything bundled?
• What prescriptions do I take, and are they covered under the Part D options I am comparing?

None of these questions has a universal right answer. That is the point — the "better" structure depends on your health, your budget, and how you like to get care.
