Enhancing claims attachment processes through digital applications

This communication applies to the Medicaid and Medicare Advantage programs for Anthem Blue Cross and Blue Shield (Anthem).

Submitting attachments electronically is the most efficient way for you to receive your claim payments fasterThat’s why we’ve made submitting digital claims attachments easier, more intuitive, and streamlined. You can now submit your claims attachments through the Claims Status Inquiry application on Availity.com.*  

Submitting attachments electronically:

  • Reduces costs associated with manual submission.
  • Reduces errors associated with matching the claim when attachments are submitted manually.
  • Reduces delays in payments.
  • Saves time: no need to copy, fax, or mail.
  • Reduces the exchange of unnecessary member information and too much personal health information sharing.

If your workflow for attachments is through electronic data interchange (EDI) submissions or directly through the Availity application, we have a solution for that.


 Didn’t submit your attachment with your claim? No problem! 

If you submitted your claim through EDI using the 837, and the PWK segment contains the attachment control number, there are three options for submitting attachments:

  1. Through the attachments dashboard inbox:
    • From Availity.com, select the Claims & Payments tab to access AttachmentsNew and your Attachments Dashboard Inbox.
  2. Through the 275 attachment:
    • Important: you must populate the PWK segment on the 837 with your document control number to ensure the claim can match to the attachment.
  3. Through the Availity.comapplication:
    • From Availity.com, select the Claims & Payments tab to run a Claims Status Inquiry to locate your claim. Find your claim and use the Send Attachments button.

If you submit your claim through the Availity application:

  1. Simply submit your attachment with your claim.
  2. If you need to add additional attachments, to add a forgotten attachment, or for claims adjustments:
    • From Availity.com, select the Claims & Payments tab and run a Claims Status Inquiry to locate your claim. Find your claim and use the Send Attachments button.
