As Pennsylvania prepares to transition to new Physical HealthChoices managed care organization (MCO) zone assignments effective July 1, 2022, MCOs new to a zone should be reaching out to providers to build their network and establish network adequacy. The Pennsylvania Department of Human Services (DHS) says that because all the future MCOs are current MCOs, there are no new contacts; there are only MCOs slated to leave the program (Aetna), to leave specific zones (United and Highmark) and to enter specific zones (Geisinger, HealthPartners). MCO contacts can be found in the HealthChoices MCO directory. The directory has all the contact information for all the plans and can be used with the list of selected plans for each zone.
