UnitedHealthcare Fax Numbers
UnitedHealthcare has no single member fax number. The right one depends on your plan, and UHC tells you where to find it. Here is how, plus the lines it publishes openly.
10 pages free every month. No credit card.
Your fax number is in your Evidence of Coverage
UnitedHealthcare sells commercial, Medicare Advantage, Part D, and Medicaid plans, and each carries its own appeals address and fax. UHC’s own instruction, for both coverage decisions and appeals, is to use “the fax number listed in your Evidence of Coverage”.
To find it: open the Plan Summary page for your plan on uhc.com, enter your ZIP code, and look for the section titled Plan Documents. Your Evidence of Coverage is there, and the appeals chapter carries the address and fax for your plan. The member services number on the back of your ID card will also read it to you.
The two lines above are the ones UHC publishes openly, and they belong to the Community Plan. If you are not a Community Plan member, they are the wrong destination.
What UnitedHealthcare members send
The paperwork that moves by fax:
- An appeal of a denied claim or a denied prior authorization, with the denial letter and any supporting records
- A Part D coverage determination or exception request, where a drug is not on the formulary
- A grievance about service or access
- An authorized representative form, when someone else is filing on the member’s behalf
Generic member inquiries and appeals sent to the wrong plan’s department are re-routed slowly, if at all. Matching the plan matters more than matching the format.
Getting the answer, not just the send
A denied claim is the start of a conversation. UnitedHealthcare responds with a determination and often with a request for more records first, and appeal windows are commonly 60 to 180 days from the denial. A request you never receive still counts against the clock.
A dedicated FaxTerra number receives those replies as PDFs in your FaxTerra inbox with an email notification. See how receiving works.
How to fax UnitedHealthcare without a fax machine
Create a free FaxTerra account with an email address, upload your appeal and its attachments as a PDF or as phone photos, enter the fax number from your Evidence of Coverage, and send. Track delivery so you have proof it arrived inside the filing window.
See how to send a fax for accepted files and page limits, how to fax an insurance claim for the general appeal process, and the OptumRx guide if the denial is about a prescription drug, since that is where many UnitedHealthcare drug requests are worked.
Frequently Asked Questions
What is the UnitedHealthcare fax number?
There is no single one. UnitedHealthcare tells members to use the fax number listed in their Evidence of Coverage, which is plan-specific. UHC publishes two Community Plan lines openly: (866) 373-1081 for expedited Part C appeals and grievances, and (866) 308-6294 for standard Part D complaints and appeals.
How do I find my Evidence of Coverage?
Go to the Plan Summary page for your plan on uhc.com and enter your ZIP code. The page that appears has a Plan Documents section containing your Evidence of Coverage, and the appeals chapter lists the address and fax for your plan.
Can I mail a UnitedHealthcare appeal instead?
Yes. UHC’s generic member appeals address is UnitedHealthcare Member Inquiry/Appeals, PO Box 30432, Salt Lake City, UT 84130-0432, but your Evidence of Coverage may list a different one for your plan. Use the one in your plan documents when they differ.
How long do I have to appeal?
Most UnitedHealthcare plans allow 180 days from receiving a claim denial to submit an appeal, and Medicare plans have their own windows. Check your plan documents, since this is one of the things that varies by plan.
Is FaxTerra affiliated with UnitedHealthcare?
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 UnitedHealthcare coverage or look up an appeal.
