Introducing the Provider Correspondence Viewer Application on Availity® Essentials 

June 21, 2023

A new Provider Correspondence Viewer application is available via Availity for providers participating with Blue Cross and Blue Shield of Illinois (BCBSIL). This application allows you to view, download and/or save specific documents associated with your National Provider Identifier (NPI) and Tax ID number. Currently, the Provider Correspondence Viewer is only available for participating BCBSIL facility providers to access and download Quarterly Average Discount Percentage reports. 

What is the Average Discount Percentage (ADP)?
BCBSIL calculates an estimated discount percentage on an averaged basis. 

  • These percentages are used to determine patient cost-share, and they appear on the member’s explanation of benefits as “ADP.”
  • These percentages are not used for purposes of calculating or making reimbursements to providers, as those are determined based on our BCBSIL network contracts.

How To Access the Provider Correspondence Viewer 
After logging in to Availity Essentials:

  • Select Payer Spaces from the navigation menu and choose “BCBSIL”
  • Within Payer Spaces, go to the Applications tab, then select the Provider Correspondence Viewer
  • Complete the required fields to obtain the quarterly ADP reports
