We’re Retiring Fax Numbers Used for Medical Prior Authorization Requests

Use Our Online Tools Instead

We’re continuously looking for ways to provide greater administrative simplicity for care providers and reduce the costs of doing business with us.

As part of this effort, we’re retiring certain fax numbers for medical prior authorization requests and asking you to use the Prior Authorization and Notification tool on Link - the same website you already use to check eligibility and benefits, manage claims, and update your demographic information.

This move to eliminate faxing supports the challenge issued by Seema Verma, the Centers for Medicare & Medicaid Services (CMS) Administrator, at the 2018 Office of the National Coordinator for Health IT Interoperability Forum. In her keynote address, Ms. Verma said, “If I could challenge the developers in this room here today to achieve one mission, it would be this: help us make every doctor’s office in America a fax free zone by 2020!”

Retiring Fax Numbers

The fax numbers we're retiring on Jan. 1, 2019 include:

Phase 1

877-269-1045

866-362-6101

866-892-4582

866-589-4848

866-255-0959

Phase 2

866-537-9371

800-789-0714

800-352-0049

800-529-1339

800-676-4798

More numbers will be added to this list over the next several months. We’ll let you know which numbers are being retired in the Network Bulletin and here on this site. Please be sure to check back for the latest information.

If we ask you for more information about a prior authorization request, you can attach it directly to the case using the Prior Authorization and Notification tool on Link. If you can’t access Link, you can use the fax number included on the request for more information.

Some Fax Numbers Won’t Retire

Some plans have a state requirement for fax capability and will continue to use their existing fax number for their members. However, you can still use the Prior Authorization and Notification tool on Link to submit requests for those members.

Requests for Additional Information

If we ask you for more information about a prior authorization request, you can attach it directly to the case using the Prior Authorization and Notification tool on Link.  If you can’t access Link, you can use the fax number included on the request for more information.

New Fax Numbers for Admission Notifications

While we encourage the use of the Prior Authorization and Notification tool on Link for Admission Notifications, we will continue to maintain a fax channel for these notifications. Effective Jan. 1, 2019, the following new fax numbers replace the retiring fax numbers for Admission Notifications:

UnitedHealthcare Commercial Admission Notifications: 844-831-5077 is replacing 800-789-0714 and 800-352-0049.

UnitedHealthcare Medicare Advantage and Medicare Special Needs Plans Admission Notifications: 844-211-2369 is replacing 800-538-1339 and 800-676-4798.

Please do not use these fax numbers for prior authorization request submissions as this will result in a misdirect and delay processing of your request. 

Other Ways to Submit a Prior Authorization Request

If you’re unable to use the Prior Authorization and Notification tool on Link you can continue to call Provider Services at 877-842-3210 to submit a request by phone.
