What a plan actually costs across Louisville & North Central Kentucky
Every county in Louisville & North Central Kentucky has plans available at a $0 monthly premium, between 38 and 63 of them depending on where you live. A $0 premium is not a $0 plan: you still pay the Medicare Part B premium, and you still pay the plan’s copays and deductibles as you use care.
The number that decides what a bad year costs is the in-network out-of-pocket maximum, not the premium. Two plans that both advertise $0 can sit thousands of dollars apart on that line, which is why the county guides list it.
Plans in this region also include Part B premium reductions worth up to $184.70 a month. Here is how the give-back actually works, including when it is worth nothing to you.
The highest 2026 overall CMS Star Rating found across Louisville & North Central Kentucky is 4.5 out of 5. A star rating measures the plan, not the fit.
Where people get care in Louisville & North Central Kentucky
The CMS registry lists 18 Medicare-registered hospitals across these counties. This is the list a plan’s network gets checked against, and the same hospital can be in network on one plan and out of network on the next.
3 of them are federally designated Critical Access Hospitals, the designation built to keep hospital care within reach of rural communities. If one of those is your closest hospital, a plan has to work for it and for the larger regional system you would be referred to for anything complicated.
What changes across nearby counties
CMS approves Medicare Advantage service areas by county. Moving across a county line can change available organizations, plan types, premiums, networks, and maximum out-of-pocket limits. Compare the county data first, then confirm the details for your ZIP code.
It also matters if you move. A move outside your plan’s service area opens a Special Enrollment Period so you can choose a plan approved where you now live; a move within the same county generally changes nothing.
