Claim Issues

To resolve a claim issue the following options are available:

  • Call the Customer Service number on the back of the member's insurance card or on the Explanation of Benefits (EOB) / Provider Remittance Advice (PRA).
  • If the claim was not processed correctly, in-network clinicians and groups can log in and file a Claim Adjustment Request via the Claim Inquiry transaction. The Claim Inquiry training module can be accessed on the Training page for instructions.
  • If the claim was submitted with inaccurate information, in-network clinicians and groups can log in and file a Corrected claim (or Void a claim) via the Claim Entry transaction. You can locate an overview of this on our Training page.
  • Access the Claim Inquiry/Adjustment Request Form and mail it to the address listed on the EOB/PRA form.
  • Contact a claims representative via Provider Express's Live Chat (for registered users) by logging in and going to Claim Inquiry (or My Submitted Claims, if the claim was submitted online). Locate the claim and towards the upper right on either "detail" page (above the member's ID #), click the link "Have questions about claim status?" to access Claims Live Chat. If you cannot locate the claim, then click the "Cannot locate claim status?" link on any of the claim pages.
