How to make a claim-payment inquiry or submit an appeal or dispute

Please follow the process outlined below to make a claim-payment inquiry or submit an appeal or dispute:


Appeals and disputes for finalized Humana Medicare, Medicaid or commercial claims can be submitted through Availity’s secure provider portal, Availity Essentials. To get started:

  1. Sign in to Availity Essentials.
  2. Use the Claim Status tool to locate the claim you want to appeal or dispute, and then select the Dispute Claim button on the claim details screen. This adds the claim to your Appeals worklist but does not submit it to Humana.
  3. You can submit the appeal or dispute to Humana immediately or wait until later and submit it from your Appeals worklist.
  4. To access your Appeals worklist at any time, go to “Claims & Payments,” then select “Appeals.”

Phone claim-payment inquiry:

Call Humana’s provider call center at 800-448-6262. Our representatives are trained to answer many of your claim questions and can initiate contact with other Humana departments when further review or research is needed.

  1. Note the reference number issued to you by the provider call center representative, as it may be needed in the future.
  2. If your issue is still outstanding and has not been adequately addressed by the call center representative, you have the option to speak to a provider call center supervisor. Based on availability, you will be connected to a supervisor or a supervisor will contact you within 48 hours of your request.
  3. In some situations, the call center representative will route your issue to an internal team at Humana. If this occurs, you will receive a letter or updated explanation of remittance from the Humana department that completes the additional review/research.
