With changes to the participating Pennsylvania Medicaid Managed Care Organizations (MCO) in each Physical HealthChoices zones, changes to Dental Coverage will begin September 1 for some plans. Each MCO uses a separate administrator for dental services. When patients or consumers are choosing MCO plans, it is important to see if their chosen provider accepts the participating dental plan under Avesis, Skygen, or United Concordia. See the coverage map on the fact sheet.
