Some drugs may have special coverage rules associated with them. These rules may limit the amount of a particular drug you can get, require that you obtain prior approval from the plan before the drug will be covered, or that you first try a certain drug to treat your medical condition before another drug will be covered. Drugs that are subject to these rules are clearly marked in the formulary guide.

If we make any formulary change that limits your ability to fill prescriptions, we will notify you at least 60 days before the change is made.
Note: If the U.S. Food and Drug Administration finds that a drug on the formulary is unsafe, or if the drug's manufacturer removes the drug from the market per Medicare Part D regulations, we immediately remove the drug from our formulary and then notify you of the change.
