33 Health Systems Split with Some Medicare Advantage Insurers as the October 15 Enrollment Window Nears

Several splits take effect October 1, leaving retirees in Columbus, New York City, Kansas City, and other areas little time to check their hospitals.

At least 33 U.S. health systems have ended, or are preparing to end, in-network contracts with one or more Medicare Advantage insurers in 2026, according to a Becker's Hospital Review tracker updated on September 22. Several of those changes take effect October 1, two weeks before Medicare's annual open enrollment period begins on October 15.
