Isturisa denied for failing step therapy by Cigna?

Cigna's specific coverage criteria for isturisa 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 Cigna Denied Isturisa Under Step Therapy

A step-therapy denial means Cigna's benefit plan requires that one or more alternative treatments be tried and documented before it will cover Isturisa (osilodrostat). This is one of the most common barriers to accessing specialty medications for rare endocrine conditions. For Cushing's disease, step-therapy requirements may specify prior trials of other agents used to manage cortisol excess or pituitary-directed treatments.

Step-therapy denials are among the most frequently overturned denial types when the medical record already documents relevant prior treatment — often, the required steps have already been taken and the denial simply reflects a documentation or submission gap.

## Federal Appeal Framework

• ACA §2719 / ERISA §503: You are entitled to a full internal appeal, and you have the right to obtain the exact step-therapy criteria Cigna applied in writing.
• Step-therapy override: Many states have enacted step-therapy override laws requiring plans to grant exceptions when (1) the required drug was previously tried and failed, (2) the required drug is contraindicated, or (3) the required drug is expected to be ineffective based on individual clinical factors. Confirm whether your state's law applies to your plan type.
• External review: If the internal appeal is denied, you may escalate to an IRO. You generally have approximately four months from the denial date to request external review — confirm the exact deadline from the denial letter.
• Expedited option: Available if your condition creates urgent medical need.

## Concrete Appeal Process and Timeline

1. Obtain Cigna's step-therapy criteria for Isturisa in writing — you are entitled to these upon request. 2. Identify which step(s) the plan requires and whether the patient's medical record already documents that those steps were completed. 3. File a written internal appeal (or step-therapy override request) within Cigna's stated deadline (typically 180 days from denial), with a complete clinical package. 4. Cigna must respond within 30 days (prospective) or 60 days (retrospective). 5. If denied internally, file for IRO external review before the four-month window closes.

## Documentation to Gather

• Diagnosis confirmation: Endocrinology records confirming the Cushing's disease diagnosis, including biochemical testing, imaging, and specialist evaluation.
• Prior-treatment history with dates and outcomes: This is the core of a step-therapy appeal. For every drug Cigna requires as a prerequisite step, document: the exact drug tried, the start and stop dates, the dose range used (from the prescriber's notes, not self-reported), and the documented clinical outcome — inadequate response, adverse effects, or clinical contraindication — per the medical record. Chart notes and office visit summaries are significantly more persuasive than a letter alone.
• Clinical severity per the chart: Current disease-activity documentation showing why further delay is medically harmful.
• Prescriber medical-necessity letter: A letter from the treating endocrinologist that addresses each required step by name, confirms what was tried and why it did not succeed for this patient, explains why Isturisa is the appropriate next therapy per the FDA prescribing information and the applicable endocrinology guidelines, and specifically invokes step-therapy override criteria if applicable.

## Criteria-Mapping Structure

Obtain Cigna's step-therapy policy for Isturisa. For each required step, map the evidence:

| Required Step (Cigna Policy) | Documented Evidence of Completion or Override | |---|---| | Step 1: [Required agent name per policy] | [Dates of trial, outcome per chart note, date of note] | | Step 2: [Required agent name per policy, if any] | [Dates of trial, outcome per chart note, date of note] | | Override criterion met (if steps not completed) | [Contraindication or expected ineffectiveness documented in chart] |

Submit the mapping with every referenced record attached. When the chart clearly shows each required step was completed — or that a recognized override criterion applies — the IRO has a straightforward basis to grant coverage.
