How Humana Evaluates ECP Requests

Humana follows Medicare guidelines for photopheresis coverage, requiring documentation that:

  • Your diagnosis qualifies (CTCL or steroid-refractory GVHD)
  • Standard treatments have failed or are contraindicated
  • A qualified specialist will oversee treatment
  • The proposed frequency follows evidence-based protocols
Note: Humana's PA denial rate is approximately 3.5% for Medicare Advantage—among the lowest of major insurers—but proper documentation remains essential.

Prepare for Your Provider Visit

Before meeting with your oncologist, dermatologist, or transplant specialist, organize your medical history to streamline the prior authorization process.

Create Your Symptom Timeline

Document your disease progression with specific dates and severity:

  • Initial diagnosis date and staging
  • Symptom progression (skin involvement, organ function)
  • Functional impact (activities limited, quality of life changes)
  • Current disease status (stable, progressing, responding)

Compile Treatment History

Your provider needs evidence of prior therapy failures to justify photopheresis:

For CTCL:

  • Topical therapies tried (corticosteroids, mechlorethamine, carmustine)
  • Systemic treatments (methotrexate, interferons, retinoids)
  • Radiation therapy details
  • Reasons for discontinuation (progression, intolerance, contraindications)

For GVHD:

  • Steroid therapy details (doses, duration, response)
  • Secondary immunosuppressants tried
  • Complications from standard treatments
  • Current immunosuppressive regimen

Document Side Effects and Contraindications

Note specific reasons why standard treatments cannot continue:

  • Intolerable side effects with dates and severity
  • Medical contraindications (organ dysfunction, drug interactions)
  • Treatment resistance with objective measures when possible

Build Your Evidence Kit

Work with your provider's office to gather supporting documentation before submitting the prior authorization.

Essential Medical Records

Request copies of:

  • Recent clinic notes (within 30 days)
  • Pathology reports confirming diagnosis
  • Imaging studies showing disease extent
  • Laboratory results (complete blood count, liver function, etc.)
  • Treatment response documentation from prior therapies

Clinical Guidelines and References

Your provider should reference established treatment guidelines:

  • NCCN Guidelines for CTCL (photopheresis as Category 2A for refractory disease)
  • ASBMT recommendations for GVHD management
  • FDA approval for Therakos CELLEX system
  • Medicare NCD 110.4 coverage criteria

Insurance Documentation

Gather from Humana:

  • Current prior authorization form
  • Your plan's specific medical policy for photopheresis
  • Benefit verification showing coverage details
  • Provider portal access for electronic submission

Medical Necessity Letter Structure

Your provider's letter to Humana must follow a specific structure to demonstrate medical necessity effectively.

  • Full name, date of birth, member ID
  • Primary diagnosis with ICD-10 codes
  • Disease stage and current status
  • Date of initial diagnosis

2. Clinical Rationale

  • Why photopheresis is medically necessary
  • Expected benefits based on published evidence
  • Risks of delaying treatment
  • Why alternative treatments are inadequate

3. Prior Treatment Documentation

  • Complete list of previous therapies
  • Dates, doses, and duration of each treatment
  • Specific reasons for failure or discontinuation
  • Objective measures of treatment response when available

4. Treatment Plan

  • Proposed ECP schedule (typically 2 consecutive days every 4 weeks initially)

Clinician Corner: Include specific language like "Patient meets Medicare NCD 110.4 criteria for extracorporeal photopheresis as palliative treatment for refractory cutaneous T-cell lymphoma with documented failure of [specific prior therapies]."

Supporting Peer-to-Peer Reviews

If Humana initially denies your request, your provider may need to participate in a peer-to-peer review with a Humana medical director.

How to Help Your Provider Prepare

Offer Scheduling Flexibility

  • Provide multiple time windows when your provider is available
  • Understand that these calls often occur within 24-72 hours of the denial

Prepare a Concise Case Summary

  • One-page overview of your diagnosis, prior treatments, and current status
  • Key points about why photopheresis is necessary now
  • Specific contraindications to alternative treatments

What Happens During the Call

Your provider will discuss:

  • Clinical rationale for photopheresis
  • Why standard treatments are inadequate
  • Expected benefits and monitoring plan
  • Alignment with Medicare coverage criteria

The outcome determines whether Humana approves the treatment or maintains the denial, triggering the appeals process.

Document Everything After Your Visit

Maintain detailed records of all communications and submissions related to your photopheresis request.

Save Key Documents

  • Submitted prior authorization with all attachments
  • Humana's determination letter (approval or denial)
  • All correspondence between your provider and Humana
  • Peer-to-peer review notes if applicable

Use Patient Portal Communications

When messaging your provider through the portal:

  • Be specific about what information you need
  • Reference dates of previous communications
  • Ask for copies of any new documentation submitted to Humana

Track Important Deadlines

  • Standard PA decision: 14 days from complete submission
  • Expedited decision: 72 hours for urgent requests
  • Appeal deadline: 65 days from denial notification
  • California IMR deadline: 6 months from denial

Practice Respectful Persistence

Effective advocacy requires consistent follow-up without overwhelming your healthcare team.

Appropriate Follow-Up Schedule

Week 1-2: Allow normal processing time Week 3: Contact provider's office if no decision received After denial: Immediate discussion about appeal strategy During appeals: Weekly check-ins on status

How to Escalate Appropriately

  1. Start with your provider's nurse or case manager
  2. Request specific timelines for next steps
  3. Offer to help gather additional documentation
  4. Ask about expedited review options if your condition is worsening

For additional support: "I understand appeals can be complex. Is there anything I can do to help gather supporting documentation?"
