Step therapy denied my drug. Can I appeal?
Yes. A step-therapy denial means the plan wants you to try a preferred drug first, and every plan must have an exception process for when you already tried it, it is contraindicated, or it is expected not to work; many states also cap step therapy by law. The appeal is a documented exception request, not an argument about the drug's merits.
What to do, in order
- Step 1
Identify the required 'step' drug
The letter names the preferred drug or class you were expected to try. Check whether you have already tried it, under this plan or a previous one.
- Step 2
Document why the step does not apply
Prior trial and failure, an adverse reaction, a contraindication, or a clinical reason it is expected to be ineffective. Dates and records matter more than adjectives.
- Step 3
File a step-therapy exception with the prescriber's statement
For Part D, 42 CFR 423.578(b) covers exceptions to step-therapy requirements with a prescriber's supporting statement. Commercial plans have an equivalent process; ask for the form.
- Step 4
Cite your state's step-therapy law if you have one
Many states require plans to grant an exception in defined circumstances and to answer within a set number of days. Your state page on Apellica lists the regulator to ask.
The deadline that applies
A step-therapy exception request is decided on the plan's coverage-determination clock (Part D: 72 hours standard, 24 hours expedited). A denied exception carries full appeal rights: at least 180 days to file on employer and ACA plans, then external review (45 CFR 147.136).

I tried the preferred drug on a different insurance. Does that count?
Usually yes, if you can document it. Pharmacy claims history, a previous plan's approval letter, or the prescriber's notes all work.
Does step therapy apply to Medicare Advantage?
MA plans may apply step therapy to Part B drugs under 42 CFR 422.136, with exception and appeal rights; Part D drugs follow the Part D exception rule.
Can I keep taking the drug while I appeal?
Ask for a transition or continuity supply. Part D plans must provide a temporary supply in defined situations; some states require continuity of care during an appeal.
