Effective August 25, 2025, Johns Hopkins hospitals, facilities, and physicians are out-of-network for MCG United Healthcare (UHC) participants. For questions about this change or help finding a new in-network provider, members can call the number on the back of their UHC ID card. Retirees who would like to change medical carriers must submit online enrollment forms by the 10th of the month to be effective the following month. Employees who would like to change medical carriers may only do so during Open Enrollment. Open Enrollment elections must be received by 5:00 PM between October 6 and October 24, 2025 with any new coverage taking effect in January 2026.
