Kaiser Permanente Insurance Fax Number — Fax Claims and Prior Authorizations
On the insurance side of Kaiser Permanente, claims, prior authorizations, enrollment changes, and appeals each route to their own fax line, which is often printed in your plan documents. A complete fax that includes your policy number and the right clinical or coding detail moves through review faster than one the department has to chase down. Confirm the correct number for your specific need before sending, since the claims desk and the authorization unit aren't the same line.

Tip: Put your policy number, and your claim number when you have one, on every page so the Kaiser Permanente Insurance team can match the fax to your file. For prior authorizations, include the diagnosis code, the procedure code, and a short clinical justification — that's what the reviewer needs to act without coming back to you for more. Keep your Send FAX Mail delivery confirmation as proof of when you submitted, especially on time-sensitive authorization requests.
