Policy Overview: How Humana Covers Photopheresis

Humana Medicare Advantage plans cover Therakos CELLEX photopheresis as a medical procedure under Part B when medically necessary for FDA-approved indications. The treatment uses CPT code 36522 for extracorporeal photopheresis and requires prior authorization due to its high-cost, specialized nature.

Plan Types and Coverage:

  • Medicare Advantage: Primary coverage pathway with prior authorization requirements
  • Commercial plans: May vary; check specific formulary and medical policy
  • Medicaid: Coverage varies by state Medicaid program

Humana processes approximately 2.2 prior authorization requests per enrollee annually, with a denial rate of 5.8% in 2024—below the industry average. This suggests most well-documented requests for appropriate indications are approved.

Medical Necessity Requirements

FDA-Approved Indications

Therakos CELLEX is FDA-approved for extracorporeal photopheresis in:

  • Cutaneous T-cell lymphoma (CTCL) that is refractory to other treatments
  • Steroid-refractory chronic graft-versus-host disease (cGVHD)

Clinical Criteria for CTCL

Your case must demonstrate:

  • Confirmed diagnosis with appropriate staging (ICD-10 codes C84.0-C84.1)
  • Failure or intolerance to at least one systemic therapy

  • Dermatologist or hematologist/oncologist oversight

Clinical Criteria for Steroid-Refractory GVHD

Documentation must show:

  • Progression within 3 days of steroid therapy at ≥2 mg/kg/day
  • No improvement within 7 days of consecutive steroid treatment
  • Incomplete response after ≥28 days of steroid therapy
  • Hematologist/oncologist confirmation of transplant status
Note: The most common denial reason is insufficient documentation of steroid failure. Ensure pharmacy records and clinical notes clearly document specific doses, duration, and lack of response.

Lack of specialist oversight Establish ongoing care with hematologist/oncologist or dermatologist; include consultation notes and treatment plan in appeal
Treatment frequency exceeds guidelines Justify schedule with clinical response data and reference Therakos prescribing guidelines showing standard 2-day every 4-week protocol
Non-covered indication Verify ICD-10 codes align with FDA-approved indications; provide additional evidence for off-label uses with peer-reviewed literature
Missing diagnostic confirmation Submit complete pathology reports, staging studies, and laboratory results confirming diagnosis and disease status
