EDI Connectivity

Establishing an EDI connection with UnitedHealthcare has never been easier.  Learn more about the benefits of EDI. You can use EDI for:

  • Claims submissions (837)

EDI transactions can be submitted to multiple payers from your Practice Management System (PMS) or Hospital Information System (HIS) through a clearinghouse. Some clearinghouses offer online solutions that allow you to upload data from your software system or manually enter the information online to generate a transaction.

Connectivity Options

  • Clearinghouse: You can use any clearinghouse with a connection to UnitedHealthcare for EDI transactions. Before choosing a clearinghouse, review EDI Clearinghouse Options to:
    • Help determine the EDI needs of your practice or facility
