UnitedHealthcare provider appeals fax number

UnitedHealthcare's appeal fax depends on the plan. For Medicare Advantage Plans, the standard appeals fax is 888-517-7113 and the urgent one is 866-373-1081.

Which UnitedHealthcare appeals fax fits my appeal?

UnitedHealthcare prints appeal faxes by plan block, and the table below gives each number with the plan and urgency it covers.

The 2026 administrative guide repeats 888-808-9123 as the Individual Exchange urgent appeal fax. The guide's claim reconsideration and appeal section gives the two-step process and the 12-month window, but it prints no fax for standard commercial employer-group appeals.

For prior authorization requests rather than appeals, see UnitedHealthcare's prior authorization fax number.

What should I send with a UnitedHealthcare appeal fax?

Send the appeal with a cover sheet that shows your name, a return fax number and the page count. UnitedHealthcare's two-step process starts with a claim reconsideration, and an appeal follows if you still disagree. An appeal must be filed within 12 months of the explanation of benefits (EOB) or provider remittance advice (PRA).

In some states, state law means claim reconsideration does not apply, and the guide sends those cases to its provider dispute resolution sections. For the rest of a cover sheet, see the cover sheet requirements for a HIPAA fax.

Can I submit a UnitedHealthcare appeal online?

Yes, UHCprovider.com is the online route, reached by signing in and opening Claims & Payments. The guide also offers chat 24/7 from the Provider Portal.

How do I fax UnitedHealthcare without a fax machine?

Fax Pigeon sends the UnitedHealthcare appeal fax from your browser, so the practice needs no fax machine. Upload the appeal and a cover sheet, and send to the UnitedHealthcare number in the table for the plan and urgency.

Every plan includes a signed BAA at signup, your own number and delivery proof for each fax. The Basic plan is $4.99 a month billed annually ($5.99 month to month) and includes 200 pages, sent plus received, with 10¢ for each extra page.

How do I confirm UnitedHealthcare received my fax?

Each fax sent to UnitedHealthcare from Fax Pigeon comes with delivery proof. To check how a fax went through, see how to tell if a fax went through. Keep the delivery proof for each fax with the appeal file, since the 12-month window runs from the EOB or PRA.

If a fax fails or UnitedHealthcare changes a number, confirm the number on the contact page named in the footer before you send again.
