Changes to the formulary (list of covered drugs)
We review our drug list on a monthly basis and make changes as necessary. Most changes are positive. An example would be adding new generics that have come on the market.
Sometimes we have to remove a drug from our formulary. An example is if the U.S. Food and Drug Administration (FDA) says a drug is unsafe or the drug maker takes the drug off the market.
Prior authorization and quantity limit
Some drugs have rules you need to follow before we cover them. These include:
Prior authorization: You or your doctor must get approval from us before we cover the drug.
Quantity limit: For certain drugs, we limit the amount you can get.
You and your doctor can ask us to make an exception to one of our coverage rules. This includes requesting an exception to a prior authorization or quantity limit rule.
There may be times where you’re taking a drug that either isn’t on our drug list or has special rules before we cover it. Learn about our transition process to see if you’re eligible for a short-term supply of medication while you consider your options. This temporary supply allows you to work with your doctor to either transition to a new drug or request an exception to continue your current drug.
