Prescription Drug Coverage
Our prescription drug formularies provide a list of medication that is covered by the plan. If you are taking a medication that is not on the list, you can ask us to make an exception. You can also ask us to waive restrictions or limitations on your drug. For example, quantity limits or step therapy restrictions.
You can use our online formulary search tool to see if a drug has any restrictions.
Requesting an Exception
You can submit a request for a coverage determination review by sending in a Coverage Determination Request form or filling out the online form.

If coverage for a specific drug has been denied, you can ask us to reconsider our decision. Please submit a request for redetermination by sending in a Redetermination Request form (PDF) by mail or submitting an online form.
We must make our decision within 72 hours of getting your prescribing provider’s supporting statement. You can request an expedited (fast) exception if you or your doctor believe that your health could be seriously harmed by waiting up to 72 hours for a decision. If your request to expedite is granted, we must give you a decision no later than 24 hours after we get your prescribing provider’s supporting statement.
