Medigap premiums vary by carrier, age, and ZIP code. The 2026 Part B premium is $202.90/month and Part B deductible is $283. Part D out-of-pocket cap is $2,100 in 2026.
Kentucky is Humana's home state, and the Louisville-based insurer maintains an especially strong MA market presence throughout the Commonwealth. Anthem Blue Cross Blue Shield of Kentucky is the other dominant carrier, and together these two carriers hold the majority of MA enrollment in the Louisville, Lexington, and northern Kentucky (Greater Cincinnati) markets. Baptist Healthcare System, KentuckyOne Health (now Trinity Health), and UK Healthcare (University of Kentucky) are the major hospital systems. Kentucky's MA enrollment of approximately 54% is above the national average, and competition in the Louisville and Lexington metros is robust.
Kentucky faces some of the most significant health challenges in the nation — consistently ranking near the bottom in health outcomes due to high rates of smoking, diabetes, and opioid-related illness. This chronic disease burden increases the importance of comprehensive Medicare coverage, and beneficiaries with multiple conditions should carefully evaluate MA plan copays for specialist visits and hospitalizations versus the flat-cost predictability of Medigap. Plan G premiums average about $126/month in Kentucky — affordable by national standards. Eastern Kentucky's Appalachian communities have significant dual-eligible (Medicare-Medicaid) populations, and Humana's DSNP plans are prominent there. There are no state-level annual Medigap switching protections.
In Kentucky, traditional Medicare combined with a Medigap supplement (typically Plan G or N) plus a stand-alone Part D plan provides nationwide access with predictable costs. Plan G covers everything except the $283 Part B deductible.
Medicare Advantage (Part C) plans bundle Medicare Parts A, B, and usually D into one private plan, often with $0 premium beyond Part B. Trade-offs include network restrictions and prior authorization. 54% of Kentucky beneficiaries currently choose MA.
No state annual GI rights; Humana is headquartered in Louisville and holds significant market presence statewide.
💡 Kentucky Pro Tip
Kentucky beneficiaries in Louisville and Lexington typically have access to 45 or more Medicare Advantage plans. Northern Kentucky (Covington, Florence) shares a market with Greater Cincinnati and may have additional Ohio-licensed plan options. Eastern Kentucky's rural Appalachian counties generally have 15 to 25 plans available.
The average Medigap Plan G premium for a 65-year-old in Kentucky is approximately $126 per month. Given the state's high prevalence of chronic conditions, Medigap's predictable cost structure is particularly valuable for Kentucky beneficiaries who anticipate frequent healthcare utilization.
Kentucky does not have a birthday rule or annual guaranteed-issue protections for Medigap. Outside your initial 6-month open enrollment at 65 or a qualifying federal guaranteed-issue event, insurers can apply medical underwriting. Given Kentucky's high rates of chronic disease, enrolling in Medigap while you are at your healthiest — at 65 — is especially important.
