How step therapy works
How step therapy works
One of these special requirements or coverage limits is known as step therapy. This is when we require a trial of a preferred drug to treat a medical condition before covering another nonpreferred 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 members who’ve already received treatment with the nonpreferred drug within the past 365 days.
