Network change for some APWUHP members

Starting Jan. 1, 2024, some of your patients who are American Postal Workers Union Health Plan (APWUHP) High Option members will use the UnitedHealthcare network.*  

These members will have new ID cards with the UnitedHealthcare logo on the front of the card. Please be sure to ask for the member’s ID card when they visit your office.
