Some drugs have coverage rules you need to follow. These include:

You or your doctor needs approval from Aetna before we cover the drug.
- Quantity limits
For certain drugs, there’s a limit on the amount of it you can fill within a certain time frame. For example, 60 tablets per 30-day prescription.
- Step therapy
We require you to try another drug first before we cover your drug.

Understanding our medication transition process

Understanding our medication transition process
There may be times when you’re taking a drug that either isn’t on our formulary (drug list) or has coverage rules. A formulary shows the drugs we cover, the tier a drug is on, any limits or coverage rules and mail-order availability.
Learn about our transition process to see if you’re eligible for a one-month supply of medication. This temporary supply allows you to work with your doctor to either transition to a new drug on our formulary or request an exception to continue your current drug.
