Step therapy is the try-this-first rule: your plan covers the expensive drug only after a lower-cost option for the same condition has failed or proven wrong for you - Medicare lists it among standard drug-plan coverage rules alongside prior authorization and quantity limits.
The defense: first-line drugs genuinely work for most patients. The harm: delay while your condition flares - which is exactly what the exception process exists for. Your moves: try the required drug with a defined failure checkpoint if it is reasonable; gather records of past failures (they usually satisfy the requirement, even from a previous insurer); and have your prescriber file an exception with the clinical reason when the required drug is wrong for you.

What to do
Common questions
What is step therapy in insurance?
Step therapy is your insurer's try-this-first rule: before the plan covers an expensive medication, it requires you to try (and fail, or be unable to tolerate) one or more lower-cost drugs for the same condition - typically generics or older brands. Medicare's own drug-plan documentation lists step therapy among the standard coverage rules alongside prior authorization and quantity limits, which tells you how mainstream the practice is. The insurer's logic is cost; the clinical defense is that first-line drugs genuinely are first-line for most patients; the harm case is delay - weeks failing a drug while your condition flares, which is why the exception process exists and matters. Your moves: if the required first drug is reasonable, try it with a clear checkpoint (what counts as failure, and when); if you have already failed it - under any previous insurer - gather the records, because that history usually satisfies the requirement immediately; and if the required drug is wrong for you specifically (allergy, interaction, contraindication), your prescriber files a step-therapy exception with the clinical reason - Medicare and marketplace rules both provide this route, and a well-documented exception often succeeds.
