A hospital system in Zanesville, Ohio, has told four of the region’s largest health insurers it plans to walk away from its contracts with them on Jan. 1, 2027, a move that would leave thousands of Medicare Advantage members choosing between a new insurance plan or an out-of-network hospital. The dispute, if it isn’t resolved, would touch some of the same carriers that dominate Medicare Advantage enrollment in Ohio and beyond.
Genesis HealthCare System Says It Was Pushed to the Brink by Care Denials
Genesis HealthCare System, based in Zanesville, notified Aetna, UnitedHealthcare, Medical Mutual of Ohio and CareSource that it intends to end its current contracts with all four insurers on Jan. 1, 2027, unless new terms are reached. The Medicare Advantage plans of Aetna, UnitedHealthcare and Medical Mutual are named in the notice, along with both the Medicare Advantage and Medicaid plans run by CareSource. Genesis President and CEO Matthew Perry described the decision as “not our first choice but our last resort,” pointing to two years of what the system calls a mounting pattern of denied claims and clawed-back payments for care that Genesis doctors had already determined was medically necessary and had already delivered.
At the center of the dispute is a count that Genesis says represents real money and real patients: the system is contesting 9,000 active denials for care already provided, which it says has produced millions of dollars in losses. Genesis argues many of those denials conflict with federal Medicare rules governing what insurers are required to cover. Because the hospital system says it does not send patients surprise bills for costs it believes an insurer owes, the unpaid balances land squarely on Genesis’s own operating budget rather than on patients directly, which the system says threatens its ability to keep enough doctors, nurses and local services in place.

What Stays the Same Through the End of 2026
Nothing changes immediately for a patient covered by any of the four insurers. Genesis says coverage remains exactly as it is through Dec. 31, 2026, and patients should keep scheduled appointments, seek care as needed and go to the emergency department in a true emergency. Commercial, employer-sponsored insurance for working families is not part of this dispute, and traditional Medigap or Medicare Supplement plans are also unaffected regardless of which company issues them. If new agreements are not reached, the change takes effect only for non-emergency care; emergency treatment is always covered at the in-network rate no matter which hospital a patient visits, under federal law.
For a retiree with a Medicare Advantage plan through one of the four carriers, the practical risk is narrower than “losing coverage” — it is losing in-network access to a specific hospital system, which can still mean sharply higher out-of-pocket costs or a requirement to travel farther for non-emergency care starting in the new year. That distinction matters because Genesis is a regional anchor for Muskingum County and the surrounding area, meaning an out-of-network outcome would push affected patients toward hospitals well outside their normal commute for routine, non-emergency treatment.
Medicare’s Enrollment Window Lines Up With the Deadline
The timing is not incidental. Medicare’s Annual Enrollment Period runs from Oct. 15 through Dec. 7, giving affected Medicare Advantage members a chance to review other plan options before the Jan. 1 contract deadline arrives. Genesis says it will hold free community sessions, publish a plain-language guide and staff a Patient Financial Advocate Hotline to answer questions, while being careful to note it cannot recommend or select a plan on a patient’s behalf. Medicaid enrollees covered through CareSource have a separate right to switch insurers at any time if Genesis goes out of network with that plan on Jan. 1, either through Ohio’s Medicaid managed-care enrollment system or by calling the state’s consumer hotline.
Genesis has also committed to specific promises around the dispute: it says it will not send a surprise bill for amounts it believes an insurer owes, will help patients appeal wrongful denials at no charge, and will share updates in plain language as negotiations continue. Whether any of the four contracts get renewed before the new year turns largely on whether the insurers and the hospital system can agree on how claims for already-delivered care get paid — a negotiation playing out in dozens of similar standoffs between health systems and national insurers across the country this enrollment season.
For now, Genesis says the burden falls on the hospital system rather than on patients: it has pledged to absorb the disputed costs itself and to fight the denials on patients’ behalf rather than pass those bills along. Whether that posture holds through the Jan. 1 deadline, or whether one or more of the four insurers reaches new terms before then, will determine how many of the roughly 9,000 disputed cases actually translate into a lost in-network hospital for a Medicare Advantage member in the new year.
