Ohio State University's Wexner Medical Center and Anthem Blue Cross and Blue Shield have reached an agreement that allows 110,000 patients to continue to use the system at in-network rates.
The new multi-year agreement takes effect Wednesday.
However, Ohio State and Anthem did not reach agreement on the health system remaining in the Anthem Medicare Advantage network. Those patients will lose access to in-network coverage beginning Wednesday.
Those wanting to stay in the Ohio State system can enroll in other Medicare Advantage plans beginning Wednesday.
Medicare Advantage patients can visit Wexner Medical Center's website to learn more about how they can keep access to services, clinicians and facilities.
The negotiations went down to the wire, with the contract expiring Tuesday.
Each side took aggressive postures during negotiations in the past month.
The Wexner Medical Center accused Anthem of underpaying claims while aggressively fighting them as Anthem had record profits of $80 billion over the past five years.
Anthem countered that Ohio State wanted to hike prices for patients and employers at rates more than three times higher than inflation, with those price hikes boosting healthcare costs for Central Ohio by $185 million over the next three years.
