Before You Start: Plan and Coverage Verification

Confirm Your Plan Type

First, verify whether your Aetna plan is regulated by Washington state law. Most individual, family, and small-group Aetna plans purchased in Washington follow state regulations, including the external review protections we'll discuss. However, if you have coverage through a large employer with a self-funded ERISA plan, different federal rules may apply.

Check your plan documents or call Aetna member services at the number on your insurance card to confirm whether Washington state regulations apply to your coverage.

What You Need to Gather

Essential Documentation Checklist

Clinical Records:

  • Pathology report confirming mycosis fungoides or Sézary syndrome
  • Current staging documentation (TNMB classification within 60 days)
  • Complete prior systemic therapy history with dates, doses, and outcomes
  • Recent laboratory results (CBC, comprehensive metabolic panel, liver function tests)
  • Current performance status assessment

Insurance Information:

  • Insurance card and member ID
  • Policy documents or summary of benefits
  • Any prior authorization forms from previous treatments
Note: Aetna requires documentation that phototherapy (PUVA/UVB) alone does not satisfy the "prior systemic therapy" requirement. Make sure your records clearly show systemic treatments like methotrexate, interferons, bexarotene, or other oral/IV therapies.

Prior Systemic Therapy Documentation

Aetna specifically looks for evidence of ≥1 prior systemic therapy for CTCL. Create a clear table including:

  • Drug name and classification
  • Dates of treatment (start/stop)
  • Dosing and schedule
  • Best response achieved
  • Reason for discontinuation (progression, intolerance, contraindication)

Examples of systemic therapies Aetna recognizes: methotrexate, interferon-α, bexarotene, romidepsin, vorinostat, brentuximab vedotin, and multi-agent chemotherapy regimens.

Submitting Your Prior Authorization Request

Step-by-Step Submission Process

1. Complete the Aetna Prior Authorization Form Your oncologist should submit the request through the Aetna provider portal or via the specialty pharmacy network. The submission must include:

  • Patient demographics and insurance information
  • Diagnosis with ICD-10 codes (C84.0x for mycosis fungoides, C84.1x for Sézary syndrome)
  • Treatment history and medical necessity justification

2. Include Medical Necessity Letter The prescribing oncologist should provide a detailed letter addressing:

  • Confirmed CTCL diagnosis and staging
  • Prior systemic therapy failures with specific details
  • Why Poteligeo is medically necessary vs. alternatives
  • Treatment plan and monitoring approach
  • Reference to FDA prescribing information and relevant guidelines

3. Submit Supporting Documentation Attach all gathered clinical records, ensuring they're recent (typically within 60-90 days for labs and staging).

CVS Specialty Pharmacy Coordination

Since Poteligeo is typically handled through CVS Caremark's specialty network, your oncologist may need to coordinate with CVS Specialty Pharmacy (1-800-237-2767) for the prior authorization process. Some practices find it helpful to call ahead and confirm the specific PA requirements for Poteligeo.

Following Up and Tracking Your Request

Medical Necessity Questions: Aetna may request additional clarification about why Poteligeo is preferred over other treatments. Your oncologist should be prepared to explain:

  • Specific reasons other systemic therapies failed or are contraindicated
  • Disease characteristics that make Poteligeo particularly appropriate
  • Expected outcomes based on clinical evidence

Documentation Gaps: Common requests include:

  • More detailed staging information
  • Laboratory results confirming adequate organ function
  • Clarification of prior therapy timelines and outcomes

Non-formulary status Request formulary exception with comparative clinical rationale
Medical necessity not established Submit additional literature support and detailed clinical justification
Missing staging information Provide complete TNMB staging with pathology and blood work

Internal Appeal Process

You have 180 days from the denial date to file an internal appeal with Aetna. The appeal should include:

  • Copy of the original denial letter
  • Additional clinical documentation addressing denial reasons
  • Updated medical necessity letter from your oncologist
  • Request for peer-to-peer review with an Aetna medical director

Peer-to-Peer Review

Your oncologist can request a phone consultation with an Aetna medical director to discuss the case. Key talking points should include:

  • Clear confirmation of relapsed/refractory CTCL meeting FDA criteria
  • Specific prior therapy failures with documentation
  • Clinical rationale for Poteligeo vs. alternatives
  • Patient's current condition and treatment urgency

Washington's External Review Process

Your Rights Under Washington Law

If Aetna's internal appeal is unsuccessful, Washington residents have strong protections through the external review process governed by RCW 48.43.535.

How External Review Works

1. Eligibility

  • You've completed Aetna's internal appeal process
  • The denial involves medical necessity, experimental treatment determinations, or coverage disputes
  • You file within 180 days of the final internal denial

2. Filing Process

  • Contact the Washington Office of Insurance Commissioner at 1-800-562-6900
  • Request external review through your health plan or directly with the OIC
  • No cost to you—Aetna pays all review fees

3. Timeline and Decision

  • Standard review: Decision within 30 days
  • Expedited review: Decision within 72 hours for urgent cases
  • Binding decision: If overturned, Aetna must provide coverage

External Review Success Rates

Washington's external review process has shown strong patient outcomes, with specialty drug appeals having particularly high overturn rates when clinical evidence supports medical necessity.

From our advocates: We've seen several Washington patients successfully overturn Aetna denials for CTCL treatments through the state's external review process. The key is providing the independent medical reviewers with complete clinical documentation that clearly shows how the patient meets FDA criteria for the medication. Most successful cases include detailed prior therapy records and staging information that wasn't adequately considered in the initial denial.

Cost Assistance and Support Programs

Manufacturer Support Programs

Kyowa Kirin Cares offers comprehensive support for Poteligeo patients:

  • Phone: 833-552-2737
  • Services: Prior authorization assistance, appeals support, copay assistance (up to $10,000/year for eligible commercially insured patients)
  • Free medication: Available for qualifying uninsured or underinsured patients

Washington State Resources

The Washington Office of Insurance Commissioner provides free consumer advocacy services to help navigate insurance disputes. Their consumer advocacy line (1-800-562-6900) can provide guidance throughout the appeals process.

Typical Out-of-Pocket Costs

For Aetna CVS Health members, Poteligeo is typically classified as a non-formulary specialty drug, which may result in higher copays. With manufacturer assistance, many commercially insured patients can reduce their out-of-pocket costs significantly.

Renewal and Re-authorization

When to Start Renewal Process

Begin the re-authorization process 30-45 days before your current approval expires. Aetna typically approves Poteligeo for 6-month initial periods, with 12-month renewals for stable patients.

Renewal Documentation

Include updated documentation showing:

  • Current disease status and response to treatment
  • Continued medical necessity
  • Absence of unacceptable toxicity
  • Recent laboratory monitoring results

Streamlining Renewals

Patients who have successfully completed initial treatment cycles often find renewals more straightforward, especially when treatment response is well-documented and no significant toxicities have occurred.

Frequently Asked Questions

How long does Aetna CVS Health prior authorization take in Washington? Standard requests typically receive decisions within 15 business days, though Washington state requirements may mandate faster turnaround times (72 hours standard, 24 hours expedited) for certain specialty drugs.

What if Poteligeo is non-formulary on my plan? You can request a formulary exception by providing clinical justification for why formulary alternatives are inappropriate or have failed. This requires detailed comparative analysis from your oncologist.

Can I request an expedited appeal in Washington? Yes, both internal appeals and external reviews can be expedited when clinical urgency is documented. Expedited external reviews must be decided within 72 hours under Washington law.

Does step therapy apply if I received prior treatment outside Washington? Step therapy requirements are based on your medical history, regardless of where treatment occurred. Documentation from out-of-state providers is acceptable as long as it clearly shows systemic therapy trials and outcomes.

What happens if my employer plan is self-funded? Self-funded ERISA plans may not be subject to Washington state external review requirements. However, many voluntarily provide similar processes, and federal ERISA appeals rights still apply.
