You can use the EDI 275 Additional Information to Support a Health Care Claim or Encounter transaction to electronically send unsolicited claim attachments to UnitedHealthcare. This refers to any additional documentation submitted with your claim that we may need for processing.
If you submit a claim and attach documentation you think we may need to process the claim, it’s considered an “unsolicited” attachment because we didn’t request it. A “solicited” attachment is documentation we ask you to send us after a claim is submitted.
Please contact your clearinghouse to determine if they’re able to submit 275 transactions to UnitedHealthcare. Please refer to the EDI 275 Companion Guide for more information.
