PHP ED denied as not medically necessary by Cigna?

Cigna's specific coverage criteria for php ed 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 Denies PHP/ED as Not Medically Necessary — and How to Appeal

Medical-necessity denials for Partial Hospitalization Program or Eating Disorder treatment are among the most common — and most successfully appealed — denial types in behavioral health. Cigna uses proprietary clinical criteria (often derived from the InterQual or Milliman guidelines) to evaluate whether a member's presentation meets the threshold for PHP-level care. Denials typically arise when the clinical documentation submitted does not clearly articulate the severity and complexity of the patient's condition in the specific language Cigna's reviewers are looking for.

### Why This Denial Is Appealable

Cigna's medical-necessity criteria must comply with the Mental Health Parity and Addiction Equity Act (MHPAEA), which prohibits applying more stringent criteria to eating disorder and mental health care than to comparable medical/surgical conditions. If the denial is based on a non-quantitative treatment limitation — such as a clinical judgment about appropriate level of care — MHPAEA requires that standard to be applied equivalently across medical and behavioral health. Additionally, independent clinical reviewers at the external review stage often reach different conclusions than Cigna's internal reviewers when the full clinical picture is presented.

### Federal Appeal Framework

• Internal appeal: File within the deadline in the denial letter (typically 180 days for ERISA plans). Request Cigna's specific clinical criteria and the specialty of the reviewing clinician.
• External review (ACA §2719 / ERISA §503): After the internal appeal, request independent external review within approximately 4 months of the final internal denial. For acute eating disorder presentations with medical risk, request expedited external review (72-hour turnaround).

### Documentation to Gather

1. Comprehensive clinical assessment — the full intake evaluation from the PHP program, including psychiatric evaluation, medical status, weight history, vital sign trends, and functional impairment. 2. Prior-treatment history — a timeline of all lower-intensity treatments tried (outpatient, intensive outpatient, prior hospitalizations) with dates, duration, and outcomes, demonstrating step-wise treatment escalation. 3. Treating clinician's medical-necessity letter — the prescriber or program psychiatrist should address Cigna's specific criteria point by point, documenting why the patient cannot be safely or effectively treated at a lower level of care. 4. Risk indicators — documentation of acute safety concerns, medical complications, or rapid clinical deterioration that support the need for PHP-level monitoring. 5. Cigna's criteria document — request the exact clinical criteria applied so the appeal can address every element.

### Criteria-Mapping Structure

Create a table with one row per criterion from Cigna's medical-necessity standard. In the response column, cite the specific chart note, vital sign trend, assessment score category (without quoting numeric thresholds), or clinical event that satisfies each element. The goal is to make it impossible for the reviewer to overlook any criterion.
