Medicare Advantage in Northern Kentucky: St. Elizabeth Healthcare and the 2026 Aetna Network Change

Northern Kentucky’s Medicare Advantage market looks simpler than it actually is. St. Elizabeth Healthcare dominates local care so thoroughly that it’s tempting to assume any plan that includes St. Elizabeth is a safe choice — but a real network change involving Aetna that took effect January 1, 2026 (and that St. Elizabeth’s own list, dated October 1, 2026, still shows in place), plus the fact that a lot of Northern Kentucky residents also see specialists across the river in Cincinnati, make this enrollment season a time to check your plan carefully for 2027 rather than assuming.

St. Elizabeth Healthcare’s Reach Across Northern Kentucky

St. Elizabeth Healthcare operates hospitals in Edgewood, Florence, Fort Thomas, Covington, and Grant County, along with St. Elizabeth Physicians locations spread across Boone, Kenton, and Campbell counties. For most Northern Kentucky Medicare beneficiaries, St. Elizabeth is where primary care, hospital stays, and a large share of specialty care happen. That reach even extends across the Ohio River into southeast Indiana, where St. Elizabeth Dearborn Hospital in Lawrenceburg is the system’s Indiana hospital — worth knowing if your family spans both sides of the river.

The Aetna Network Change Every St. Elizabeth Patient Should Know About

According to St. Elizabeth Healthcare’s own published insurance participation list, Aetna Medicare Advantage plans went out of network at St. Elizabeth Healthcare and St. Elizabeth Physicians effective January 1, 2026. The most recent version of that list we reviewed, dated October 1, 2026, still shows Aetna Medicare Advantage as out of network, while Aetna’s commercial (non-Medicare) plans are listed as participating. We have not found any announcement that Aetna Medicare Advantage will return to St. Elizabeth’s network for 2027, but these contracts can change, so confirm with St. Elizabeth and Aetna before you rely on either answer. If you’re enrolled in an Aetna Medicare Advantage plan and see any St. Elizabeth provider — your primary doctor, a specialist, or any of the system’s hospitals — confirm directly how your specific plan treats those providers rather than assuming your coverage carries over unchanged. An HMO plan generally pays for non-emergency care only inside its network, while some PPO plans cover out-of-network care at a higher cost, so the type of plan you have matters.

The Annual Enrollment Period, October 15 through December 7, is your main window to switch plans for the following year; this year, that means choosing coverage for 2027 by December 7, 2026. If you’re already enrolled in a Medicare Advantage plan and miss that window, the Medicare Advantage Open Enrollment Period, January 1 through March 31, still allows one change — to a different Medicare Advantage plan or back to Original Medicare, but not adding a stand-alone drug plan — useful if a network surprise catches you off guard after the new year has already started.

Why Northern Kentucky Isn’t a Typical Single-System Market

On paper, Northern Kentucky looks like a one-system market with St. Elizabeth Healthcare so dominant locally. In practice, it isn’t — Northern Kentucky is genuinely part of the greater Cincinnati metro area, close enough that Cincinnati/Northern Kentucky International Airport itself sits in Boone County, Kentucky, not Ohio. A lot of Florence, Covington, and Newport-area Medicare beneficiaries cross the river regularly for specialty care at Cincinnati systems like UC Health, TriHealth, and The Christ Hospital, whether for a specific specialist, a second opinion, or simply because that’s where a family has always gone. A Medicare Advantage plan that only covers St. Elizabeth in-network can leave that Cincinnati side of your care completely uncovered, which is a genuinely different risk than what a single-state, single-system market like Dayton or Columbus deals with.

If You Have a Medicare Supplement, None of This Touches You

Worth saying plainly: if you have Original Medicare paired with a Medicare Supplement plan rather than a Medicare Advantage plan, neither the Aetna network change nor the cross-river question affects you. Standard Supplement plans work alongside Original Medicare, which is accepted by St. Elizabeth, the major Cincinnati systems, and any other provider nationwide who takes Medicare — there’s no plan network to lose access to, no state line to think about, and no annual plan contract that could quietly drop a hospital system you rely on. (The one exception is Medicare SELECT, a type of Supplement that does use a provider network, so ask which kind you are looking at.) For Northern Kentucky residents whose care genuinely spans both sides of the river, this is exactly the kind of situation that makes a Supplement plan worth a serious look.

HMO vs. PPO Across a State Line

Medicare Advantage HMO plans generally require you to stay inside the plan’s network (except for emergencies and a few other situations) and often need a referral to see a specialist. PPO plans allow you to go outside the network, typically at a higher cost, without a referral. In a market where a real share of residents cross the Ohio River for specialty care, that distinction carries extra weight — an HMO built tightly around St. Elizabeth’s network won’t help much if your cardiologist or oncologist is at a Cincinnati system on the other side of the river. If your care genuinely spans both, a PPO’s added flexibility can be worth the higher premium, though PPOs usually cost you more for out-of-network care, so check the specific cost sharing.

Top Carriers Serving Northern Kentucky

As of St. Elizabeth’s insurance list dated October 1, 2026, Medicare Advantage plans from Anthem Blue Cross and Blue Shield, AARP/UnitedHealthcare, Humana, Wellcare (by Allwell), and HealthSpring (formerly Cigna) are listed as participating, while Aetna Medicare Advantage is listed as out of network and Devoted Health’s Medicare Advantage plans are listed as out of network effective January 1, 2027. A carrier appearing on that list does not guarantee that every one of its plans, or every doctor, is in network for 2027, so check each plan’s provider directory. Plan availability shifts by county across Boone, Kenton, and Campbell, and which plans actually include your specific doctors depends heavily on whether those doctors are part of St. Elizabeth, a Cincinnati system, or both.

Understanding Medicare Star Ratings

Medicare rates every Medicare Advantage plan on a 5-star scale annually, based on member satisfaction, customer service, and health outcomes. Network fit and drug coverage for your specific situation still come first, but between two plans that both check those boxes, the star rating can be a useful tiebreaker. It does not tell you whether a particular hospital or doctor is in the plan’s network, which is why network fit comes first.

Extra Benefits Worth Comparing Closely

Dental, vision, and hearing benefits vary considerably between Medicare Advantage plans in this market — some cover only a basic annual exam, while others include a real allowance toward dentures, glasses, or hearing aids. Some plans in this market also include an over-the-counter allowance, a fitness benefit like SilverSneakers, or transportation assistance to medical appointments, which matters more than usual if your appointments sometimes mean a trip across the river into Cincinnati. These extras are worth comparing item by item rather than assuming “dental and vision included” means the same coverage from one plan to the next.

A Client Example

A Fort Thomas client enrolled in an Aetna Medicare Advantage plan came to us after hearing about the St. Elizabeth network change from her sister-in-law, unsure whether it actually applied to her own plan. It did — her primary doctor and the cardiologist she’d seen for years, both part of St. Elizabeth, would no longer be in-network starting January 1. We compared her options during the Annual Enrollment Period and moved her to a plan that kept her full care team in-network, without disrupting relationships with doctors she’d trusted for over a decade.

What to Check Before You Choose

• Whether St. Elizabeth Healthcare and any specific doctors you see there are actually in-network for the plan you’re considering, given the Aetna Medicare Advantage change that began January 1, 2026, and confirmed for the plan year you are choosing (2027)
• Whether the plan also covers your specialists in Cincinnati, if any of your care happens across the river
• Whether your regular prescriptions are covered on the plan’s drug formulary, and at what tier
• Whether an HMO’s lower cost and network restriction fits your situation, or a PPO’s added flexibility is worth the higher premium or higher out-of-network cost sharing

Special Needs Plans: A Less-Known Option

Beyond standard HMO and PPO Medicare Advantage plans, some Northern Kentucky residents may qualify for a Special Needs Plan (SNP) — built for people with certain chronic conditions, those who qualify for both Medicare and Medicaid, or those in an institutional care setting. SNPs often include care coordination and benefits tailored to the qualifying condition, but eligibility is specific. Worth asking about if any of these situations apply to you or a family member.

Frequently Asked Questions

Is Aetna Medicare Advantage out of network at St. Elizabeth Healthcare?

According to St. Elizabeth Healthcare’s own published insurance list, Aetna Medicare Advantage plans went out of network at St. Elizabeth Healthcare and St. Elizabeth Physicians effective January 1, 2026, and the list dated October 1, 2026 still shows them as out of network. It applies to Aetna Medicare Advantage, not to Original Medicare, and the same list shows Aetna commercial plans as participating. If you’re enrolled in an Aetna Medicare Advantage plan and see a St. Elizabeth provider, confirm how your specific plan covers that care, and recheck for 2027 because contract status can change.

Can I still switch plans if I missed the Annual Enrollment Period?

Yes, if you’re already enrolled in a Medicare Advantage plan. The Medicare Advantage Open Enrollment Period, January 1 through March 31, allows one change, either to a different Medicare Advantage plan or back to Original Medicare (you cannot add a stand-alone drug plan during this period).

Do I need a plan that covers Cincinnati if I only see St. Elizabeth doctors?

Not necessarily — if all of your care genuinely stays within St. Elizabeth Healthcare, a plan built around that network alone can work fine. It’s worth double-checking, though, since a lot of Northern Kentucky families end up seeing at least one specialist in Cincinnati without fully realizing it changes their network needs.

Is a Medicare Advantage plan cheaper than Original Medicare plus a Supplement?

Often lower in monthly premium, sometimes $0, but with more variable out-of-pocket costs and a network to work within. Original Medicare plus a Supplement typically costs more monthly but offers predictable costs and access to any doctor who accepts Medicare, including St. Elizabeth and the major Cincinnati systems, without a network distinction (Medicare SELECT policies are the exception).

Do Medicare Advantage plans in Northern Kentucky include prescription drug coverage?

Most do, bundled directly into the plan. Confirming this and checking your specific medications against the plan’s formulary is one of the first things worth verifying before enrolling.

Once You’ve Chosen a Plan

Enrolling doesn’t end the relationship with your agent — network contracts, formularies, and coverage details can and do change year to year, as the Aetna situation makes clear. A good agent checks in with you at least annually rather than only at the moment of enrollment. We track when each client’s plan is up for its yearly review and reach out proactively, rather than waiting for a network change to surprise you mid-year.
