Drug List search tool and updates

We make it easy to manage your medicine. For your peace of mind, it helps to know that a drug you take is covered. Our List of Covered Drugs (Formulary) shows the drugs we cover, any limits or requirements and mail order availability. Stay up-to-date with our Drug List. 

Our Drug List search tool 


There are many different things you can do with our Drug List search tool. You can: 


  • Search for your medicine by name or class 

  • Find generic alternatives to a medicine  

  • See if a medicine has quantity limits or requires prior authorization  

Some drugs have rules you need to follow before we cover them. These include:


  • Prior authorization: You or your doctor needs approval from us before we’ll cover the drug.
  • Quantity limits: For certain drugs, we limit the amount you can get.
  • Step therapy: We require you to try another drug first before we’ll cover your drug.

Requirements or limits on Part B drugs

Under Aetna Assure Premier Plus (HMO D-SNP), some drugs may have special requirements or coverage limits. We’ll help you find the information you need.



How step therapy works

Some medically administered Part B drugs, like injectables or biologics, may have additional requirements or coverage limits. That may include step therapy, where we require a trial of a preferred drug to treat a medical condition before covering another non-preferred drug. 


Here’s an example:

If Drug A and Drug B both treat a medical condition, we may prefer Drug A and require a trial of it first. If Drug A does not work, we’ll then cover Drug B. The listed preferred products should be used first.


Note: The step therapy requirement does not apply to patients who’ve already received treatment with the non-preferred drug within the past 365 days.
