Step Therapy

Step therapy protocols require patients to try and fail on cheaper drugs or treatments before the insurer will cover a more expensive option.

Definition

Step therapy, also called 'fail first,' is a utilization management technique where an insurer requires a patient to try and demonstrate failure of one or more lower-cost treatments before it will cover the physician's originally requested, typically more expensive treatment. For example, a plan might require a patient with rheumatoid arthritis to try two cheaper disease-modifying drugs before approving an expensive biologic. Step therapy protocols are intended to reduce costs while achieving equivalent clinical outcomes, but critics argue they delay appropriate care. Most states now have step therapy override laws requiring insurers to honor a physician's clinical determination when the patient has previously tried and failed the required medications or when step therapy would cause harm. Medicare Advantage plans are subject to CMS step therapy rules that include exception pathways. When a step therapy protocol is applied to your claim, request the specific criteria in writing and work with your physician to document medical necessity for skipping steps.
