Updated ID cards for enhanced system

For the past several years, we’ve been implementing an enhanced claims processing system designed to improve the efficiency of your benefit lookups, payments and referral experiences. As part of these modernizations, we’re issuing new member ID cards to renewing members. To ensure your claims are processed accurately and without delay, please update your billing system with the new information provided on the member ID cards. 

Note: The system releases will not affect your access to the UnitedHealthcare Provider Portal or your ability to perform tasks, such as prior authorizations, claim submissions or benefit determinations.
