Premera Blue Cross Fax Number — Prior Authorizations, Claims, and Appeals

Premera Blue Cross, which serves members in Washington and Alaska, routes faxes by department, so utilization management, claims, and appeals each publish their own number. A prior-authorization request goes to the fax line printed on the authorization form for that service or medication, and an appeal goes to the number on the denial notice you are contesting. Providers confirm current fax lines through Premera's provider portal, while members find claims and customer-service contacts on the back of the ID card. Because the correct line depends on the request type and plan, read the form in front of you instead of reusing a saved number.

What You Can Fax to Premera Blue Cross

Tip: A Premera Blue Cross fax about a patient carries protected health information, so use a HIPAA-eligible service and put the member ID and date of birth on every page in case pages separate during scanning. Send FAX Mail's HIPAA-eligible Business plan ($79.99/month) supports this and provides a transmission receipt you can file against the authorization or appeal deadline. List the authorization or claim reference number on the cover sheet so reviewers can tie your fax to the open request.

Faxing to Premera Blue Cross — FAQ

It is printed in the submission instructions on the current prior-authorization request form for the specific service or drug, available through the Premera provider portal. Using a current form avoids sending the request to a line that has since changed.

The turnaround depends on whether the request is standard or expedited and is stated in Premera's authorization guidelines. Keep your transmission receipt so you can show the submission date if a decision runs past the expected window.

Appeal instructions, including the fax line and deadline, are printed on the denial or coverage-determination notice regardless of the member's state. Fax the appeal to the number on that notice before the stated date and save the delivery confirmation.

Coordination-of-benefits and other-coverage forms are usually returned to the department that requested them, using the fax line on the form itself. Include the member ID and any reference number so Premera can update the correct record.
