Casper Hospital Exploring Affiliation With Banner Health Posted by John Axtell Date: February 01, 2020 5 Views CASPER, Wyo. (AP) – Wyoming’s largest hospital is looking into affiliation with Banner Health, a major regional health care organization. Wyoming Medical Center in Casper says a nonbinding agreement with Banner will allow both to agree on terms before deciding on affiliation. The potential deal apparently will not mean a merger. Nonprofit Banner Health runs nearly 30 hospitals across the West, with Torrington among 3 in Wyoming, as well as labs, emergency rooms, clinics and surgical centers. Affiliation would make Wyoming Medical Center the latest Wyoming hospital to partner with a larger, out-of-state provider. Ivinson Memorial Hospital in Laramie and Cheyenne Regional Medical Center in Cheyenne have reached agreements with Colorado-based UC Health.
