As part of our streamlined provider claims payment dispute process, Anthem Blue Cross (Anthem) introduced the ability to submit claim payment disputes via Availity, for members enrolled in our Anthem Blue Cross Medicaid and Medicare Advantage benefit plans. Effective November 20, 2021, providers will now also be able to submit claim payment disputes via Availity for Anthem’s Commercial lines of business.

As a reminder, unlike inquiries about claims status, provider disputes, or requests for additional information, provider claim payment disputes occur after a claim is finalized, and a provider disagrees with the claim payment Anthem has issued.  Some examples include manual processing errors, contract interpretation, reduced payments, code editing, eligibility, timely filing *and other health plan denials.

Anthem’s streamlined provider claim dispute process utilizing Availity across all Anthem lines of business, allows a more cohesive and efficient approach for providers when:

  • Filing a claim payment dispute.
  • Sending supporting documentation to Anthem.
  • Checking the status of a claim payment dispute.
  • Viewing the history of a claim payment dispute.


* Reminder, Anthem will consider reimbursement of a claim that has been denied due to failure to meet timely filing if you can: 1) provide documentation that the claim was submitted within the timely filing requirements or 2) demonstrate good cause exists.

Reminder on how the provider claim’s payment dispute process works

For Anthem, the provider claim’s payment dispute process consists of the following:

Commercial claims payment dispute:
A written notice to Anthem challenging, appealing or requesting reconsideration of a claim or clinical determination that has been denied, adjusted, contested, or seeking resolution of a contract dispute; or disputing a request for reimbursement of an overpayment of a claim. Providers may submit the claim dispute in writing effective November 20, 2021, via Availity; providers are encouraged to submit all commercial disputes via Availity.


When submitting a claim payment dispute for commercial claims, please include as much information as you can including but not limited to the following:

  • A clear explanation of the basis for which the Provider or Facility believes the payment amount should be
  • Whether the request for reimbursement is for the overpayment of a claim, contest, denial, adjustment, or other action

Please refer to the Provider Manual for additional details

Anthem will issue a written determination stating the pertinent facts and explaining the reasons for its determination within 45 working days after the date of receipt of the dispute.


Submitting commercial claim payment disputes in writing

When submitting a claim payment dispute in writing, providers must include the Claim Information/ Adjustment Request Form and submit it to:


Anthem Blue Cross

P.O. Box 60007

Los Angeles, CA 90060-0007

Anthem’s review and other providers’ options
