Step Therapy

Step therapy is a plan requirement that a member try one or more lower-cost medications (and document that they didn't work or weren't tolerated) before the plan will cover a higher-cost alternative. Also called "fail-first," it's a utilization-management tool used most often for chronic-condition drugs where multiple therapeutic options exist — biologics for autoimmune conditions, injectable diabetes drugs, migraine preventives.

The logic on the plan side is straightforward: if a cheaper drug works, use it; if it doesn't, move up the ladder. The critique from providers and patients is that step therapy can force people through weeks or months of ineffective treatment when the prescriber already has clinical judgment about what will work. It can also override treatment decisions made by out-of-plan providers — a member switching plans might be forced to restart the step-therapy protocol on a drug their previous specialist already prescribed. Many states have passed step-therapy reform laws requiring plans to allow exceptions in specific clinical circumstances, honor prior successful treatment history, and respond to exception requests within defined timeframes.

The takeaway: if your plan requires step therapy for a drug your provider has already prescribed based on documented history, request a step-therapy exception in writing citing prior treatment. Most plans grant these when the clinical rationale is documented; the denial is often paperwork, not medicine.
