Kaiser Permanente Washington Authorization Fax Form

Community providers use this Kaiser Permanente Washington fax form to request referral or authorization review from KP Review Services when sending a member to a specialist, facility or for equipment. A clinician meets it when referring a Kaiser Permanente Washington member for a service needing approval. Routine requests are processed within 5 days unless more information is needed.

Who completes it

The requesting community provider or office completes every field: requestor, member, referring provider and clinic, referred-to provider, facility, diagnosis and procedure codes and place of service. The urgent attestation is signed only when the request is urgent.

Submitting and payment

How to submit it
Kaiser Permanente Washington prefers the Referral Request application in OneHealthPort; otherwise print the completed form and fax it to KP Review Services.

Good to know

  • Every field on the form is required, and Kaiser Permanente says missing information will delay the request.
  • Urgent means delay could seriously jeopardize life or health, the ability to regain maximum function, or lead to ongoing severe pain; urgent referrals are often processed within one calendar day.
  • Up to two diagnosis codes fit on the form; check the box to show clinical information or medical records are attached.
  • Each Kaiser Permanente region runs its own referral and authorization process, so this form applies only to Washington.
