Tirzepatide denied for failing step therapy by Anthem?

Anthem's specific coverage criteria for tirzepatide are defined in its own published medical/coverage policy and the FDA-approved prescribing label. A successful appeal documents that your medical records satisfy each criterion those sources list — confirmed diagnosis, any required prior treatments (with dates and outcomes), and clinical severity. If the exact criteria weren't included with your denial, request them in writing; your appeal then maps each requirement to the matching fact in your chart.

## Why Anthem Requires Step Therapy Before Tirzepatide

Anthem's step-therapy (also called "fail-first") requirement for tirzepatide mandates that a patient try and document failure of one or more lower-tier or lower-cost medications before Anthem will approve tirzepatide. The specific agents and the definition of "failure" are listed in Anthem's published step-therapy criteria. Denials under this reason typically occur because the chart does not document the required trial(s), because documentation of the prior trial is incomplete, or because the prior agent was prescribed by a different provider whose records were not included.

Step-therapy requirements are increasingly regulated at the state level. Several states have enacted laws requiring insurers to grant step-therapy exceptions when a patient documents clinical contraindication, prior failure, or a history suggesting a required step is clinically inappropriate. If your state has a step-therapy protection law, cite it in your appeal.

## Your Federal Appeal Rights

• ACA §2719 / External Review: After exhausting internal appeals, you may request IRO external review. The external-review request window is typically around four months from the final internal denial date — confirm the exact deadline from your denial letter.
• ERISA §503 Full-and-Fair Review: ERISA plans must disclose the specific step-therapy criteria applied and consider evidence of prior treatment history submitted on appeal.
• State Step-Therapy Protections: Many states require insurers to grant an exception when a prior step is clinically contraindicated, was previously tried and failed, or would cause clinical harm. Check your state's insurance department website or ask your prescriber.
• Expedited Review: Available when clinical urgency is present; request it simultaneously with the standard appeal.

## Appeal Timeline

1. Obtain Anthem's step-therapy criteria document for tirzepatide — it will list which prior agents are required and how failure is defined. 2. Work with your prescriber to compile complete documentation of each required step. 3. File the internal appeal with complete records within the timeframe on your denial letter. 4. If denied, request external review before the deadline — IROs frequently overturn step-therapy denials when documentation is thorough.

## Documentation to Gather

• Prior therapy records for each required step: Prescription records, pharmacy fill history, office notes, and lab results documenting the name, dates of initiation and discontinuation, doses, and clinical outcome (inadequate response, adverse effect, contraindication) for every agent Anthem's step-therapy protocol requires.
• Prescriber step-therapy exception letter: A letter explaining why tirzepatide is the appropriate therapy at this point in the patient's treatment history, addressing each required prior step by name and outcome.
• Clinical severity documentation: Chart notes confirming the severity of the underlying condition and the clinical impact of inadequate control or prior treatment failure.
• State law citation (if applicable): If your state has a step-therapy exception law, cite the statute or regulation number in the appeal letter.

## Criteria-Mapping Structure

List every required step from Anthem's criteria document in a table. For each step, record: (1) name of the required agent, (2) date the patient tried it, (3) duration, (4) outcome or reason it was inappropriate, and (5) the source document in the chart. If a required step was never tried because the prescriber determined it was clinically inappropriate, that judgment must be documented in a signed note and included as an exhibit. A complete, step-by-step evidence table is the single most effective tool for overturning these denials.
