Prime Therapeutics: Fax Numbers for Prior Authorization

Is fax still accepted at Prime Therapeutics?

Prime Therapeutics continues to accept fax for prior authorization requests, confirmed directly on its provider prior authorization hub. Unlike some peers in this cluster, Prime Therapeutics does not frame fax as being phased out, it presents electronic prior authorization (ePA) through CoverMyMeds as an available option, not a mandated replacement. Fax routing depends on the member's plan and the specific drug or request form. Do not assume that one Choice/commercial number covers every request.

Where to fax, by plan and form

• Choice Xolair prior authorization: the official form, revised October 1, 2026, lists fax 888-272-1349.
• Choice self-administered oncology prior authorization: the official form, revised October 1, 2026, also lists 888-272-1349.
• Other drugs or plans: use the fax printed on the current form applicable to that member and request. Do not reuse either example without checking the form.

What replaced fax at Prime Therapeutics?

Nothing has replaced fax outright. Prime Therapeutics promotes ePA via CoverMyMeds as a faster alternative, but its own materials treat fax and ePA as coexisting options rather than framing one as a legacy channel being retired.

Which route should I use?

1. Identify the exact health plan on the member's ID card, Prime Therapeutics' fax numbers are plan-specific, not universal.
2. Use the current plan- and drug-specific form from Prime Therapeutics or the member’s health plan rather than a generic number found elsewhere.
3. Consider CoverMyMeds ePA if speed matters, it's a genuine option here, not required.
