Experience the future and be a part of Anthem Blue Cross (Anthem) digital-first initiative by submitting your corrected claims using the Availity Portal or through Electronic Data Interchange (EDI).


The corrected claims process begins when a claim has already been adjudicated. Multiple types of errors that occur can typically be corrected quickly with the options below. As a reminder, the corrected claim must be received within the timely filing.


Availity Portal Corrected Claim Submission

You can recreate a claim and submit it as a replacement or cancellation (void) of the original claim, if the Anthem has already accepted the original claim for processing.

Follow these steps:

  1. In the Availity Portal menu, select Claims & Payments, and then select ProfessionalClaim or Facility Claim, depending on which type of claim you want to correct.
  2. Enter the claim information, and set the billing frequency and payer control number as follows:
    • Replacement of Prior Claim or Void/Cancel of Prior Claim
    • Billing Frequency(or Frequency Type) field, in the Claim Information section (for professional and facility claims) or Ancillary Claim/Treatment Information section (for dental claims).
    • Set the Payer Control Number (ICN / DCN)(or Payer Claim Control Number) field to the claim number assigned to the claim by the Anthem. You can obtain this number from the 835 ERA or Remittance Inquiry on Payer Spaces.
  3. Submit the claim.

EDI Corrected Claim Submission


Corrected claims submitted electronically must also have the applicable frequency code.


Frequency Code: Indicates the claim is a correction of a previously submitted and adjudicated claim. Providers should use one of the following:
