Prescription drug coverage rules:

Some drugs have coverage rules you need to follow. Here are a few examples:

  • Prior authorization - You or your doctor must get approval from Aetna before we cover the drug.
  • Quantity limits - Some drugs have a limit on how much you can fill in a certain time frame. Example: 60 tablets for a 30-day supply.
  • Step therapy - You may need to try a different drug first before we cover your drug.

Need a coverage exception? Here are two ways you can ask.


You or your doctor can request an exception to one of our coverage rules.

 

Here’s how you can ask:

  1. Request an exception online.
  2. Call Customer Care at the number on your Aetna member ID card.

Understanding our medication transition process

Sometimes you may take a drug that is not on our formulary (drug list) or has coverage rules. A formulary is our list of covered drugs. It also shows you:

 

  • The tier for each drug
  • Any limits or rules
  • If it is available by mail order

Temporary supply

 

If this happens, you may be able to get a one-month temporary supply.

 

This supply gives you time to:

 

  • Talk with your doctor about switching to a drug we cover
  • Ask for an exception so you can stay on your current drug
