Indication Requirements

Poteligeo coverage requires documented diagnosis of:

  • Relapsed or refractory mycosis fungoides (ICD-10: C84.0)
  • Relapsed or refractory Sézary syndrome (ICD-10: C84.1)

The patient must be ≥18 years old with disease that has progressed after at least one prior systemic therapy. Off-label use for other cutaneous T-cell lymphoma subtypes may require additional clinical justification and literature support.

Required documentation:

  • Pathology report confirming CTCL diagnosis
  • Complete TNMB staging (see Required Diagnostics section)
  • Disease progression notes after prior therapy

Step Therapy & Exceptions

UnitedHealthcare mandates evidence of failure, intolerance, or inadequate response to at least one prior systemic therapy. Acceptable prior treatments include:

Qualifying systemic therapies:

  • Extracorporeal photopheresis
  • Interferon-α
  • Bexarotene
  • Methotrexate
  • HDAC inhibitors (vorinostat, romidepsin)
  • Other systemic retinoids
Important: Topical therapies or radiation alone do NOT satisfy step therapy requirements.

Medical exception pathways:

  • Document contraindications to standard therapies
  • Provide evidence of intolerance (specific adverse events, dates, doses)
  • Include clinical rationale for why Poteligeo is medically necessary as next-line therapy

When patients have tried multiple therapies, list each with:

  • Drug name and dates of treatment
  • Maximum dose achieved
  • Reason for discontinuation
  • Clinical response (stable, progression, partial response)

Required Diagnostics

Complete TNMB staging documentation is essential for approval:

T (Skin Assessment)

  • Percentage of body surface area involved
  • Lesion types (patches, plaques, tumors, erythroderma)
  • Clinical photography (optional but helpful)

N (Lymph Node Evaluation)

  • Physical examination findings
  • Lymph node biopsy results if nodes >1.5cm or clinically suspicious
  • Histopathology report for N1-N3 staging

M (Visceral Disease Assessment)

  • CT chest/abdomen/pelvis with contrast (if clinically indicated)
  • PET/CT for suspected advanced disease
  • Documentation of organomegaly or extranodal involvement

B (Blood Involvement)

  • Flow cytometry for Sézary cell quantification (preferred over manual count)
  • Absolute Sézary cell count per μL
  • T-cell receptor gene rearrangement studies
  • Complete blood count with differential

Timing requirements: Staging studies should be completed within 3 months of PA submission to ensure current disease status.

Site of Care & Specialty Pharmacy

Specialty Pharmacy Requirements

  • Poteligeo must be sourced through UnitedHealthcare-approved specialty pharmacy
  • OptumRx is the primary specialty pharmacy for most UHC plans
  • Coordinate drug shipment with infusion center prior to scheduled treatment

Infusion Site Requirements

  • Must be in-network facility contracted with UnitedHealthcare
  • Hospital outpatient departments, freestanding infusion centers, or qualified physician offices
  • Site of care policies may direct to lower-cost settings unless medically justified

Network verification steps:

  1. Confirm infusion center is UHC-contracted
  2. Verify specialty pharmacy can deliver to chosen site
  3. Obtain site of care authorization if hospital-based infusion is required

For patients needing hospital-based infusion, document clinical rationale such as:

  • Complex comorbidities requiring hospital-level monitoring
  • History of severe infusion reactions
  • Need for concurrent procedures or treatments

Sample "Meets Criteria" Narrative

"This 65-year-old patient has biopsy-confirmed relapsed mycosis fungoides (ICD-10 C84.0) with stage IIB disease (T3N0M0B0) based on complete TNMB staging performed [date]. The patient has failed prior systemic therapy with bexarotene (discontinued due to hypertriglyceridemia after 4 months) and interferon-α (discontinued due to flu-like symptoms and disease progression after 6 months). Current disease shows clinical progression with new tumor lesions and increased pruritus significantly impacting quality of life. Poteligeo (mogamulizumab) is FDA-approved for relapsed/refractory mycosis fungoides after ≥1 prior systemic therapy and is recommended by NCCN guidelines as appropriate second-line therapy. The patient will be monitored by our board-certified dermatologist with experience in CTCL management."

Key elements included:

  • Specific diagnosis with ICD-10 code
  • Complete staging information
  • Documentation of prior therapy failures with reasons
  • Clinical progression evidence
  • Reference to FDA approval and guidelines
  • Prescriber qualifications

Common Denial Reasons & Fixes

Denial Reason How to Overturn Required Documentation
Incomplete staging Submit full TNMB workup Pathology, imaging, flow cytometry reports
Insufficient prior therapy Document systemic therapy trials Treatment records with dates, doses, outcomes
Prescriber not qualified Confirm specialist credentials Board certification, fellowship training
Missing clinical notes Provide comprehensive progress notes Recent visits, response assessments, staging
Site of care not approved Request exception or change site Clinical justification for hospital-based care
Non-formulary status Submit medical necessity appeal Literature support, guideline references

Pro tip: The most common reason for initial denial is incomplete documentation of prior systemic therapy. Ensure you have detailed records showing specific drugs tried, durations, maximum doses achieved, and reasons for discontinuation.
