  • Prior Authorization Criteria

    For some drugs, you or your provider needs to get approval from Commonwealth Care Alliance before we will agree to cover the drug for you. Sometimes the requirement for getting approval in advance helps guide appropriate use of certain drugs. If you do not get this approval, your drug might not be covered by the plan.

    These documents provide a list of drugs that require prior authorization:

  • Step Therapy Criteria

    Step therapy encourages you to try less costly but just as effective drugs before Commonwealth Care Alliance 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.

Changes to the formulary
Commonwealth Care Alliance may add or remove drugs from our formulary during the year. If we remove a drug or make a change regarding a drug you use, we will notify you of the change at least 60 days before the date that the change becomes effective. However, if the Food and Drug Administration (FDA) determines that a drug on our formulary is unsafe, or if the drug’s manufacturer removes the drug from the market, we will immediately remove the drug from our formulary.

What if my drug is not on the formulary?
