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.

Did you know that certain prescription medicines are available as a 90-day supply? Medicine that you take on a long-term basis to manage your health is called a “maintenance drug.” A 90-day supply makes it easier to keep taking the medicine you need to feel your best. You may also be eligible to receive your long-term medications through free home delivery.
