EDI 277 A3 Format Example

EDI 277 A3 Healthcare Claim Status Response

What is the EDI 277 Transaction Set?

The EDI 277 Healthcare Claim Status Notification response transaction set and format have been specified by HIPAA 5010 standards for the electronic exchange transmission of claims status notifications. The EDI 277 A3 transaction is an acknowledgment returned as an unprocessable claim. Therefore, the claim or encounter has been rejected and has not been entered into the adjudication system.

Note: The EDI 277 transaction set has been specified by HIPAA for the submission of claim status information to 1) respond to a previously received EDI 276 Claim Status Inquiry, 2) to request that a payer provide additional information about a submitted claim (no 276 involved), or 3) for a payer to provide claim status information to a provider via the EDI 277, without having received a 276.
