Medical Necessity Requirements

Humana follows Medicare's National Coverage Determination for photopheresis, but adds its own documentation requirements. Your treatment must meet specific criteria based on your diagnosis.

For CTCL (Cutaneous T-Cell Lymphoma)

  • Confirmed diagnosis of mycosis fungoides or Sézary syndrome
  • Disease unresponsive to at least one prior systemic therapy
  • Specialist (oncologist or dermatologist) oversight required
  • Documentation of disease stage and prior treatment failures

For Chronic GVHD

  • Confirmed chronic GVHD after allogeneic stem cell transplant
  • Steroid-refractory status documented by one of:
    • Disease progression within 3-5 days of high-dose steroids (≥2 mg/kg/day)
    • No improvement within 5-7 days of steroid therapy
    • Incomplete response after 28+ days of treatment
  • Transplant specialist or hematologist supervision
Clinician Corner: Your medical necessity letter should include the specific steroid regimen tried (drug, dose, duration), objective measures of treatment failure, and why ECP is the appropriate next step. Reference current NCCN guidelines and include any contraindications to alternative therapies like ruxolitinib.

Step-by-Step: Getting Prior Authorization

1. Gather Required Documentation (Patient/Family)

Collect insurance cards, medical records, and previous treatment history. Request records from all treating physicians if care was received at multiple facilities.

2. Schedule Specialist Consultation (if needed)

Ensure you're under the care of an appropriate specialist—oncologist for CTCL, transplant specialist or hematologist for GVHD.

3. Provider Submits PA Request

Your doctor submits the prior authorization through Humana's provider portal or by fax with required forms and clinical documentation.

4. Humana Review Process (30 days standard)

Humana's medical team reviews your case. They may request additional information or schedule a peer-to-peer review with your physician.

5. Decision and Next Steps

  • Approved: Proceed with treatment at an approved infusion center
  • Denied: Review denial letter carefully and consider appeal within 65 days

6. Treatment Initiation

Schedule treatments at a Humana-contracted hospital outpatient infusion center with certified ECP capability.

Common Denial Reasons & Solutions

Denial Reason How to Address
"Not medically necessary" Provide detailed specialist letter with clinical rationale and guideline citations
"Experimental/investigational" Reference FDA approval and Medicare NCD coverage
Insufficient steroid failure documentation Submit complete records showing specific doses, duration, and objective failure measures
Wrong site of care Ensure treatment is planned at contracted hospital outpatient facility
Missing specialist oversight Add consultation notes from appropriate specialist

Appeals Process in Illinois

Illinois residents have robust appeal rights when Humana denies coverage. The state's external review process provides an additional layer of protection.

Internal Appeal (First Level)

  • Deadline: 65 days from denial notice
  • Timeline: Humana must respond within 30 days (pre-service) or 60 days (post-service)
  • How to file: Online through Humana member portal or by mail

External Review (Illinois-Specific)

If Humana upholds the denial, Illinois law provides for independent external review:

  • Deadline: 30 days from final internal denial (shorter than many states)
  • Process: Independent Review Organization (IRO) with specialist expertise
  • Timeline: Decision within 5 business days of receiving records
  • Cost: Free to consumers; insurers pay review costs
  • Binding: IRO decision compels coverage if overturned

From Our Advocates: We've seen ECP appeals succeed when families work closely with their transplant team to document steroid-refractory status comprehensively. One key is showing not just that steroids didn't work, but why alternative therapies weren't appropriate—contraindications, prior failures, or specialist recommendations can strengthen the medical necessity case significantly.
