Answer Box: Getting Therakos CELLEX Covered by Aetna (CVS Health) in New Jersey

Aetna (CVS Health) covers Therakos CELLEX photopheresis for cutaneous T-cell lymphoma (CTCL) and steroid-refractory graft-versus-host disease (GVHD) when specific medical necessity criteria are met. Your fastest path to approval: 1) Have your specialist (dermatologist, hematologist, or oncologist) document failed prior therapies and submit a comprehensive prior authorization request, 2) Ensure treatment will occur at an in-network hospital outpatient facility, and 3) Include pathology reports, treatment history, and a detailed medical necessity letter. If denied, you have 180 days to appeal internally and can request external review through New Jersey's IHCAP program administered by Maximus Federal Services.

Policy Overview: How Aetna (CVS Health) Covers Photopheresis

Aetna (CVS Health) treats extracorporeal photopheresis (ECP) using the Therakos CELLEX system as a medical procedure rather than a pharmacy benefit. This means coverage flows through your medical benefits, not prescription drug coverage, and requires prior authorization for most plan types including HMO, PPO, and Medicare Advantage plans in New Jersey.

The official Aetna clinical policy bulletin specifies that photopheresis is considered medically necessary only for specific FDA-approved and evidence-based indications. Coverage decisions are made based on diagnosis, prior treatment history, and specialist oversight requirements.

Covered Indications	CTCL, steroid-refractory GVHD	Pathology reports, ICD-10 codes	Aetna Policy
Step Therapy	Failed prior systemic treatments	Treatment timeline with outcomes	Aetna Policy

Medical Necessity Requirements

Aetna (CVS Health) has strict criteria for what qualifies as "medically necessary" for photopheresis. Your condition must fall into one of these categories:

For Cutaneous T-Cell Lymphoma (CTCL)

Confirmed diagnosis of erythrodermic CTCL, including mycosis fungoides or Sézary syndrome
Pathology confirmation with appropriate ICD-10 coding (C84.0, C84.1, or related codes)
Disease staging documentation showing advanced or refractory disease

For Graft-Versus-Host Disease (GVHD)

Documented steroid-refractory acute or chronic GVHD
Transplant records confirming GVHD diagnosis and grading
Failed response to corticosteroids plus at least one additional immunosuppressive agent

Note: Aetna considers photopheresis for other conditions (such as solid organ transplant rejection or autoimmune disorders) as experimental and typically does not provide coverage.

Step Therapy and Prior Treatment Documentation

Before approving photopheresis, Aetna (CVS Health) requires evidence that you've tried and failed standard treatments. This "step therapy" requirement varies by diagnosis:

CTCL Step Therapy Requirements

Topical therapies (if appropriate for disease stage)
At least one systemic therapy such as:
- Interferons (alpha or gamma)
- Retinoids (bexarotene)
- Chemotherapy agents
- Targeted therapies (if applicable)

GVHD Step Therapy Requirements

First-line corticosteroids with documented inadequate response
Second-line immunosuppressive therapy such as:
- Cyclosporine or tacrolimus
- Methotrexate
- Azathioprine
- Antithymocyte globulin

Documentation Checklist for Prior Treatments

Drug names, doses, and duration for each therapy attempted
Dates of treatment and reasons for discontinuation
Clinical response (or lack thereof) with objective measures when possible
Adverse effects or contraindications that prevented continued use

Clinician Corner: Your medical necessity letter should include a chronological treatment history with specific details about why each prior therapy was inadequate. Reference specific lab values, imaging results, or clinical assessments that demonstrate treatment failure.

Frequency Limits and Treatment Schedules

Aetna (CVS Health) typically approves photopheresis on a schedule that aligns with FDA labeling and clinical guidelines:

Standard Treatment Schedule

Initial phase: 2 consecutive treatment days every 4 weeks
Maximum frequency: 2 sessions per week
Typical duration: 6-7 cycles for initial evaluation of response

Higher Frequency Requests

If your specialist believes you need more frequent treatments, additional documentation is required:

Clinical justification for increased frequency
Evidence of inadequate response to standard scheduling
Monitoring plan for potential adverse effects

Reauthorization Requirements

Clinical response assessment every 6 months
Continued medical necessity documentation
Updated treatment plan from supervising specialist

Site of Care and Specialist Oversight Requirements

Photopheresis must be performed at approved facilities with appropriate specialist oversight:

Approved Sites of Care

Hospital outpatient infusion centers
Certified apheresis facilities with trained staff
Academic medical centers with transplant or oncology programs

Important: Photopheresis cannot be performed at home, through retail pharmacies, or at non-certified facilities. CVS Caremark Specialty Pharmacy provides coordination support but does not directly administer ECP treatments.

Required Specialist Oversight

For CTCL: Dermatologist, hematologist, or oncologist with CTCL experience
For GVHD: Hematologist, transplant specialist, or oncologist
Ongoing supervision: Regular assessments and treatment plan modifications

Evidence to Support Medical Necessity

When building your case for coverage, include evidence from these authoritative sources:

Clinical Guidelines

NCCN Guidelines for CTCL or GVHD management
FDA labeling for Therakos CELLEX system
Peer-reviewed literature supporting photopheresis efficacy
Professional society recommendations (American Society of Apheresis, etc.)

Sample Medical Necessity Paragraph

"Mr./Ms. [Patient] has biopsy-confirmed erythrodermic CTCL (ICD-10: C84.0) with extensive skin involvement documented by [date] pathology report. Despite adequate trials of topical corticosteroids (6 months), interferon-alpha (4 months, discontinued due to flu-like symptoms), and bexarotene (3 months, discontinued due to hypertriglyceridemia), the patient continues to have progressive disease with [specific clinical findings]. Based on NCCN guidelines and published literature demonstrating efficacy in refractory CTCL, extracorporeal photopheresis is medically necessary as the next appropriate treatment option."

Common Denial Reasons and How to Fix Them

Denial Reason	How to Overturn	Documents to Include
"Not medically necessary"	Submit detailed treatment history showing failed therapies	Chronological treatment timeline, specialist notes, objective response measures
"Experimental/investigational"	Reference FDA approval and clinical guidelines	FDA labeling, NCCN guidelines, peer-reviewed studies
"Insufficient documentation"	Provide complete medical records	Pathology reports, imaging, lab results, progress notes
"Frequency exceeds policy"	Justify increased frequency with clinical evidence	Specialist letter explaining need for accelerated schedule
"Non-contracted facility"	Verify network status or request exception	Facility network verification, exception request form

Appeals Process in New Jersey

If Aetna (CVS Health) denies coverage for photopheresis, New Jersey provides a robust appeals process:

Step 1: Internal Appeal to Aetna

How to file: Online portal, phone, or written request
Expedited option: Available if delay would jeopardize your health (72-hour decision)
Standard timeline: 30-45 days for decision

Step 2: External Review Through IHCAP

If your internal appeal is denied, you can request an independent external review through New Jersey's Independent Health Care Appeals Program (IHCAP):

Administrator: Maximus Federal Services
Timeline to file: Within 4 months (120 days) of final internal denial
Review timeline: 45 days for standard review, expedited for urgent cases
Cost: Free to you (insurer pays all costs)
Decision: Binding on Aetna if overturned

Required Documents for Appeals

Copy of original denial letter
All medical records supporting necessity
Specialist letters addressing denial reasons
Clinical guidelines or literature supporting treatment
Treatment history with outcomes

Frequently Asked Questions
