Does Baptist Health Take Your Medicare Advantage Plan? Lexington's 2026 Network Status
Here is the short answer for Lexington's three hospital systems. Three carriers are accepted at all three: Humana, Aetna, and Anthem. Those three sell 25 of the 40 Medicare Advantage plans a Fayette County resident can enroll in for 2026. UnitedHealthcare and WellCare are in-network at UK HealthCare and CHI Saint Joseph, but out-of-network at Baptist Health, which is another 11 plans. That single split decides where thousands of Lexington-area seniors can affordably get care, and most people find out after they have already enrolled. Below is the carrier-by-carrier picture for all three systems, where each status came from, and how to confirm it for your own plan.
First: this only matters if you have (or are considering) Medicare Advantage
Original Medicare has no network. If you have Original Medicare, with or without a Medigap supplement, every hospital in this article accepts you: UK HealthCare, Baptist Health, CHI Saint Joseph, and nearly every doctor in the Bluegrass. You can stop reading and go enjoy your day.
Medicare Advantage plans are private plans with contracts. Whether Baptist or UK is "in-network" depends on whether that hospital and your specific insurer have a signed contract this year. Those contracts are exactly what changed in Lexington, twice, in the last three years.
Baptist Health: who is in and who is out (2026)
Baptist Health publishes a payer status table on its own website covering Baptist Health hospitals and Baptist Health Medical Group providers statewide, which includes Baptist Health Lexington and the Baptist Health Hamburg campus. As of my July 2026 check, it shows:
| Coverage | Status at Baptist Health | Notes |
|---|---|---|
| Original Medicare | Accepted | No network applies |
| All Medigap (Supplement) plans | Accepted | Pays alongside Original Medicare |
| Humana Medicare Advantage | In-network | Hospitals and medical group |
| Aetna Medicare Advantage | In-network | Listed as of Jan 1, 2026 |
| Anthem Medicare Advantage | In-network | Listed as of Jan 1, 2026 |
| UnitedHealthcare Medicare Advantage | Out-of-network | Since January 2024 |
| WellCare Medicare Advantage | Out-of-network | Since January 2024 |
| Essence Medicare Advantage | Out-of-network | Effective January 1, 2026 |
Source: Baptist Health's published Medicare Advantage payer status table, baptisthealth.com. Verified July 2026. Status is subject to change; confirm before you rely on it.
The UnitedHealthcare and WellCare splits are not new: Baptist ended those contracts in January 2024, citing claim denials and payment delays, and they have not returned as of this writing. The Essence change is new for 2026. Essence Healthcare entered the Lexington market with heavy advertising, and plenty of folks who enrolled did not realize Baptist facilities would leave its network on January 1, 2026.
UK HealthCare: who is in (2026)
UK HealthCare, which includes UK Albert B. Chandler Hospital, UK Good Samaritan, and the Markey Cancer Center, publishes an in-network insurance list on ukhealthcare.uky.edu. As of my July 2026 check, its Medicare Advantage section includes:
- Aetna Medicare Advantage
- Anthem Medicare Advantage
- Humana Choice (PPO) and Humana Gold Choice (PFFS) plans. Note the plan types: if you have a different Humana plan, such as an HMO, verify it specifically.
- UnitedHealthcare Medicare Advantage
- WellCare Medicare Advantage
- CareSource Advantage (Medicare). Worth knowing: CareSource does not sell a Medicare Advantage plan anywhere in Kentucky for 2026, so this line matters only if you moved here holding one from another state.
Source: UK HealthCare's published in-network insurance plans page, ukhealthcare.uky.edu. Verified July 2026. Individual plans under a carrier can differ; confirm your exact plan.
CHI Saint Joseph: the carriers Saint Joseph accepts (2026)
CHI Saint Joseph Health operates Saint Joseph Hospital and Saint Joseph East in Lexington, plus hospitals across the surrounding counties. It does not publish a clean in-and-out payer table the way Baptist does, so this list is what Saint Joseph confirms it accepts, as of August 2026:
- Aetna Medicare Advantage
- Anthem Medicare Advantage
- Devoted Health Medicare Advantage (effective January 1, 2025)
- Humana Medicare Advantage
- UnitedHealthcare Medicare Advantage
- WellCare Medicare Advantage
- Passport by Molina Medicare Advantage. In Fayette County, Passport's only 2026 plan is a Dual Eligible Special Needs Plan, so this one applies to you only if you have both Medicare and Medicaid.
Source: CHI Saint Joseph Health accepted Medicare Advantage carriers, confirmed August 2026. Saint Joseph publishes an accepted-plans page but notes it is not exhaustive, so treat a carrier's absence here as "unconfirmed," not as "out-of-network." Confirm at (844) 303-9355 with your plan name.
All three systems, side by side
This is the table most people actually want. The left column lists every Medicare Advantage carrier a Fayette County resident can enroll in for 2026 during general enrollment, with how many plans each one sells here, so you can see how much of the market each row represents.
| Carrier (2026 Fayette plans) | Baptist Health | UK HealthCare | CHI Saint Joseph |
|---|---|---|---|
| Original Medicare + any Medigap plan | Accepted | Accepted | Accepted |
| Humana (16 plans) | In-network | In-network* | Accepted |
| UnitedHealthcare (6 plans) | Out-of-network | In-network | Accepted |
| WellCare (5 plans) | Out-of-network | In-network | Accepted |
| Anthem (5 plans) | In-network | In-network | Accepted |
| Aetna (4 plans) | In-network | In-network | Accepted |
| Devoted Health (2 plans) | Not listed, call | Not listed, call | Accepted |
| Essence Healthcare (2 plans) | Out-of-network | Not listed, call | Not listed, call |
*UK's published list names Humana Choice (PPO) and Humana Gold Choice (PFFS) specifically. If you hold a Humana HMO, verify that plan by name. "Not listed, call" means the system does not publish a status for that carrier either way, so it is unconfirmed, not confirmed out. Only Baptist publishes explicit out-of-network statuses. Plan counts: CMS CY2026 Medicare Advantage Landscape file, Fayette County, general-enrollment plans only, pulled August 2026. Network statuses: Baptist and UK verified July 2026, Saint Joseph confirmed August 2026.
Two carriers show up on a hospital's list without being something you can actually buy here, and it is worth naming them so nobody wastes an afternoon: CareSource appears on UK's in-network list, but CareSource sells no Medicare Advantage plan in any Kentucky county for 2026. Passport by Molina appears on Saint Joseph's list, but its only Fayette plan this year is a Dual Eligible Special Needs Plan, which is limited to people who have both Medicare and Medicaid.
Why this changes, and why it caught so many neighbors off guard
Hospital-insurer contracts are renegotiated on their own schedules, and either side can walk away. Kentucky has seen more of this lately, not less: carriers trimmed their Medicare Advantage footprints for 2026 (UnitedHealthcare alone left 109 counties nationwide), benefits budgets tightened, and hospitals pushed back on payment practices. The result is that a plan that was fine when you picked it can quietly stop covering your hospital the next January.
You are not powerless about it. Every fall, during the Annual Enrollment Period (October 15 to December 7), you can switch plans for the coming year. Your plan also has to send you an Annual Notice of Change each September. The trap is that most people never read it. A yearly plan review exists precisely to catch a network break before it costs you.
How to verify your own plan in 10 minutes (do this before you enroll or switch)
If all three answers agree, you can enroll with confidence. If they disagree, believe the hospital, and pick a different plan or get help sorting it out.
Common questions
Does Baptist Health take UnitedHealthcare Medicare Advantage in 2026?
No. Baptist Health hospitals and Baptist Health Medical Group providers, including Baptist Health Lexington, list UnitedHealthcare Medicare Advantage as out-of-network on Baptist's own published payer table, and have since January 2024. UK HealthCare's published in-network list does include UnitedHealthcare Medicare Advantage, so UHC members in Lexington are typically in-network at UK but not at Baptist. Verified July 2026; always confirm current status before enrolling.
Which Medicare Advantage plans are in-network at Baptist Health Lexington in 2026?
On Baptist Health's own published payer status table (verified July 2026), Humana Medicare Advantage, Aetna Medicare Advantage, and Anthem Medicare Advantage are listed as in-network for Baptist Health hospitals and medical group providers. UnitedHealthcare, WellCare, and Essence Medicare Advantage are listed as out-of-network. Original Medicare and all Medicare Supplement (Medigap) plans are accepted.
Does UK HealthCare take Medicare Advantage plans?
Yes. As of July 2026, UK HealthCare's published in-network insurance list includes Aetna Medicare Advantage, Anthem Medicare Advantage, Humana Choice (PPO) and Humana Gold Choice (PFFS) plans, UnitedHealthcare Medicare Advantage, WellCare Medicare Advantage, and CareSource Advantage. Note that CareSource does not sell a Medicare Advantage plan in Kentucky for 2026, so that entry only applies to someone who moved here holding one. Coverage can vary by specific plan, so confirm your exact plan with UK HealthCare and the insurer before care.
Which Medicare Advantage plans does CHI Saint Joseph accept in Lexington?
As of August 2026, CHI Saint Joseph Health confirms it accepts Aetna, Anthem, Devoted Health (effective January 1, 2025), Humana, UnitedHealthcare, WellCare, and Passport by Molina Medicare Advantage at Saint Joseph Hospital and Saint Joseph East. Saint Joseph does not publish an exhaustive in-and-out payer table, so a carrier missing from that list is unconfirmed rather than confirmed out-of-network. Call (844) 303-9355 with your plan name to check.
Which Medicare Advantage carriers work at all three Lexington hospital systems?
Humana, Aetna, and Anthem are the three carriers currently in-network or accepted at Baptist Health, UK HealthCare, and CHI Saint Joseph. Those three sell 25 of the 40 Medicare Advantage plans available to a Fayette County resident in 2026, per the CMS CY2026 Landscape file. UnitedHealthcare and WellCare work at UK and Saint Joseph but not at Baptist. Original Medicare with a Medigap plan has no network and is accepted at all three regardless.
Does Baptist Health accept Original Medicare and Medigap plans?
Yes. Original Medicare has no network, and Baptist Health, UK HealthCare, and CHI Saint Joseph all accept it. Medicare Supplement (Medigap) plans pay alongside Original Medicare, so they are accepted anywhere Original Medicare is. Network worries only apply to Medicare Advantage plans.
What happened between Baptist Health and Essence Medicare Advantage?
Essence Healthcare, a Medicare Advantage insurer that entered the Lexington market, went out-of-network with Baptist Health hospitals and providers effective January 1, 2026, per Baptist's published payer table. Essence members can still use other Lexington systems that contract with Essence, but Baptist facilities are out-of-network.
