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

- 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.
