Prime Therapeutics PA/Step Therapy Choice Fax Form

Prime Therapeutics, the pharmacy benefit manager for many Blue Cross and Blue Shield plans, uses this three-page form for prior authorization and step therapy requests for members on its commercial Choice formularies. A prescriber meets it when a prescription rejects for prior authorization or a step requirement. The form handles prospective, concurrent and retrospective reviews and asks why the requested drug was chosen over alternatives.

Who completes it

Only the prescriber may complete the form, including patient and prescriber details, drug information, criteria questions and the attestation signature.

Submitting and payment

How to submit it
Fax or mail the form to Prime Therapeutics, or submit an electronic PA through CoverMyMeds, which Prime says gives faster coverage determinations.

Good to know

  • Mark Urgent only when the prescriber believes waiting for a standard review could seriously harm the patient's life, health or ability to regain maximum function.
  • The criteria ask whether the patient takes the drug now and how it was obtained, such as insurance or samples, and whether it was used in the past 90 days.
  • List previously tried and failed drugs with dates, specifying brand-name, generic or over-the-counter products.
  • Incomplete forms are returned for more information, and the health plan may audit the medical records behind the answers.
