The Pharmacy Preapproval Program includes four types of reviews:
You can use our Rx Search tool to see if a drug falls into one or more of these categories.
To request a review, the pharmacy or the provider must contact our Pharmacy services center at 888-261-1756 or fax a drug-specific online form (see Preapproval drugs section).
Sometimes a pharmacy can do a one-time override for urgently needed medication.
Learn more about emergency fills.
A drug list exception review is required if the Rx plan listed on the member's ID card is X1, X3, X4, M1, M2, M4, or B2 and the drug you've selected in the Rx Search tool displays the nondrug list symbol. For these drugs, submit a review using the Pharmacy Drug List Exception Request fax form. If we approve the exception, your cost will be charged, based on whether the drug is generic, brand, or specialty. Learn more about drug benefit levels.
After we review the medication, we fax a decision to the requesting provider and send the customer a confirmation letter about the prescription coverage decision.
Medications for certain conditions—such as migraines, diabetes, or high blood pressure—may need to meet certain requirements before a prescription is covered. See the Preapproval drugs section to check if the drug requires a preapproval, quantity limit, or step therapy review.
Type the name of the drug to view preapproval criteria, the drug's corresponding medical policy, and a link to an online fax form. As another option, you can use the Pharmacy Preapproval Request fax form to submit all types of pharmacy authorization requests.
Note: The Rx search tool shows drugs that require pharmacy preapproval common to all plans. To find out if your medicine requires pharmacy preapproval, sign in and access Express Scripts via your Pharmacy Services page.
