Preferred Drug Lists

Finding your medication(s) on the Drug Lists

  • You can search by the drug name.
  • The lists include drugs that are generally covered

Care1st Health Plan Arizona has three approved drug lists (formularies); Integrated, Behavioral and Crisis. You can view the drug lists using the following links:

Prior Authorization

To prescribe a drug that requires prior authorization and/or a drug that is not on the Care1st preferred drug lists, providers can submit a request using CoverMyMeds or by completing and faxing the Pharmacy Prior Authorization Request Form to 602-778-8387.

Electronic Prior authorizations (ePA) are a quick and simple way to complete PA requests. The ePA process is HIPAA compliant and allows for faster determinations. You can also easily track your ePA requests.

Submit your Prior authorization (PA) requests electronically through our preferred solution CoverMyMeds:

**If prior authorization is not obtained in advance, the member will not be able to fill the prescription at the pharmacy, causing a delay in obtaining needed medication.


Prior Auth Criteria

Care1st utilizes Prior Authorization criteria that has been reviewed and approved by AHCCCS. To review prior authorization requirements for a drug that requires PA or is not on the Care1st formulary visit the AHCCCS Pharmacy page.

Additional PA criteria may apply. For drug specific PA criteria not included on the AHCCCS Fee-For-Service PDF (link above), please call provider services at 866-560-4042 to request a copy of the PA criteria.
