UnitedHealthcare has introduced a new online portal allowing out-of-network providers to electronically register their taxpayer ID numbers  and practice demographics. Prior to submitting claims to UnitedHealthcare as an out-of-network provider, the following information is required and can now be uploaded through the portal, avoiding potential delays with claims processing and payments.

  • Taxpayer identification number (TIN)
  • PDF of W-9 form
  • Federal tax classification
  • Medical license restrictions (if any)
  • Valid National Provider Identifier (NPI) number
  • Primary servicing address
  • Proof of servicing address
  • Primary billing address
  • Proof of billing address
  • Primary remittance address
  • Proof of remittance address

The digital TIN registration takes about 10 minutes to complete and is available to both providers and third-party billing companies.
