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.
