Step therapy override denials
Step therapy (also called 'fail-first') requires patients to try a plan-preferred medication and demonstrate failure or intolerance before the plan will cover the prescribed drug. Federal and many state laws require plans to allow exception requests when the step is clinically inappropriate.
The rule that controls this: Federal and state step-therapy override laws require an exception for contraindication, intolerance, prior failure, or likely ineffectiveness.

How we approach the appeal
File a step-therapy override request citing one of the standard override grounds: (1) prior trial and failure of the preferred drug, (2) contraindication to the preferred drug, (3) intolerance / adverse reaction, (4) likely-ineffective based on clinical characteristics, or (5) stability on current therapy. Attach prior pharmacy records from any plan to demonstrate prior trials. Many state laws now codify a tight response timeline for step-therapy overrides, cite the applicable statute.
Standard exception: typically 72 hours. Expedited urgent: 24 hours. Most state step-therapy override laws require response within 72 hours or less.
