One number for grievances and appeals

Humana’s Appeal or Grievance Form says the completed form and any supporting documents “may be sent to us by mail or fax”, and prints the Grievance and Appeals Department fax as (888) 556-2128, with mail going to P.O. Box 14165, Lexington, KY 40512-4165.

Humana treats grievances and appeals on the same form. A grievance is a complaint about service or quality. An appeal contests a coverage decision. The form asks you to identify which one you are filing, because the deadlines and the review path differ.

What to attach

The form asks for the member’s details and the reason, and Humana names the attachments that help:

  • Receipts, if you paid out of pocket for something you believe should have been covered
  • Medical records relevant to the decision
  • A letter from your doctor explaining why the service or drug was needed
  • Documentation of your authority, if you are the person acting on the member’s behalf

A form with a doctor’s letter is typically three to five pages, which a one-time credit pack covers from about 10¢ a page if it runs past your free monthly allowance.

Getting Humana’s answer, not just the send

Humana responds to a grievance or appeal in writing, and frequently asks for more information before deciding. Medicare appeal windows are short, so a request you never see is a decision made without your evidence.

A dedicated FaxTerra number receives those replies as PDFs in your FaxTerra inbox with an email notification. See how receiving works.

How to fax Humana without a fax machine

Create a free FaxTerra account with an email address, upload the completed form and attachments as a PDF or as phone photos, enter the Humana fax number, and send. Track delivery so you have proof it arrived inside the filing window.

FAQ

Frequently Asked Questions

What is the Humana fax number for appeals?

Humana prints (888) 556-2128 on its Appeal or Grievance Form for the Grievance and Appeals Department, with mail going to P.O. Box 14165, Lexington, KY 40512-4165.

What is the difference between a grievance and an appeal?

A grievance is a complaint about service, access, or quality of care. An appeal contests a coverage or payment decision. Humana uses one form for both and asks you to mark which you are filing, since the review paths differ.

Can someone file a Humana appeal for me?

Yes, with authorization on file. Humana requires a valid appointment of representative or equivalent legal documentation before it will accept an appeal from anyone other than the member.

Should I send receipts with a Humana appeal?

Yes, if you paid out of pocket. Humana’s form names receipts, medical records, and a letter from your doctor as the supporting documents worth attaching.

Is FaxTerra affiliated with Humana?

No. FaxTerra is an independent online fax service. We deliver your document to the number you enter and confirm when it arrives. We cannot see your Humana plan or the status of an appeal.
