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.
