The formulary is the list of medications chosen by a committee of doctors and pharmacists to help you maximize the value of your prescription benefit. These generic and brand-name medications are available at a lower cost. The use of non-preferred drugs will result in a higher copay. Sharing the formulary with your doctor helps ensure you get the best value, saving money for you and the State of Arizona.

Changes to the formulary can occur during the Plan Year every quarter. Medications that no longer offer the best therapeutic value for the Plan are removed from the formulary. When your prescription is filled, ask your pharmacist to verify the current cost or copay amount. Members can log into the MedImpact Pharmacy website for complete formulary information.

Preferred Drug List 

  • The Preferred Drug List is a list of commonly prescribed medications within select classes of drugs covered on your formulary.

  • Specialty medications are limited to a 31-day supply and may be obtained only at a participating retail pharmacy or through the MedImpact Specialty Pharmacy. Members may enroll in services by calling 877-391-1103 (TTY dial 711) or emailing us at [email protected].

  • COVID-19 testing is also widely available, please visit azdhs.gov.  Please help prevent the spread of COVID-19 by getting tested if you have symptoms and isolating if you test positive.

Some drugs may have additional requirements or limits on coverage. These requirements may include the following:

  • Prior Authorization - Prescriptions for certain medications may require clinical approval before they can be filled, even with a valid prescription. These prescriptions may be limited to quantity, frequency, and dosage or have age restrictions. You, your local pharmacy, or your physician may initiate the authorization process by contacting MedImpact.  Learn more about Prior Authorization, including processing times, in this flyer.
  • Step Therapy Program promotes safe, cost-effective, and clinically appropriate medications. This requirement encourages you to try less costly but just as effective drugs before the Plan covers another drug. For example, if Drug A and Drug B treat the same medical condition, the Plan may require you to try Drug A first. If Drug A does not work for you, the Plan will then cover Drug B. This requirement to try a different drug first is called “step therapy.” Learn more about Step Therapy in this flyer.
  • Quantity Limits - Certain drugs have limits on the amount of the drug that will be covered.
  • Coordination of Benefits - Benefit Options does not coordinate pharmacy benefits.
  • Out-of-Network & International - The cost of prescriptions filled out-of-Network will not be reimbursed. No international pharmacy services are covered. Fill prescriptions before your trip and take your prescriptions with you—no coverage for lost, stolen, or damaged medication.

Smoking cessation help is available at no cost to you. All help services are free and available in English and Spanish. To take the first step toward quitting, call 844-866-3727.
