What This Guide Covers

This guide helps patients with generalized lipodystrophy and their healthcare providers navigate Aetna CVS Health's prior authorization process for Myalept (metreleptin) in Washington state. Myalept is a specialty medication that requires strict documentation and REMS program compliance.

Who this helps:

  • Patients diagnosed with congenital or acquired generalized lipodystrophy
  • Healthcare providers prescribing Myalept
  • Caregivers managing insurance approvals

Expected outcomes: With proper documentation, most medically appropriate requests for Myalept are approved. Washington's strong consumer protection laws provide additional appeal rights if initially denied.

Before You Start: Verify Your Coverage

Check Your Plan Type

  • Commercial Aetna plans: Follow standard prior authorization process
  • Medicaid/Apple Health: May have additional state requirements
  • Self-funded employer plans: May follow different appeals processes

Confirm Pharmacy Benefit Coverage

Myalept is typically covered under the pharmacy benefit and dispensed through CVS Specialty. Verify your plan includes specialty pharmacy coverage.

Formulary Status

Check if Myalept is on your plan's formulary through the Aetna provider portal or member website. Non-formulary status doesn't prevent coverage but may require additional documentation.

Gather Required Documentation

Essential Clinical Documentation

  • Diagnosis confirmation: Clinical notes documenting generalized lipodystrophy with ICD-10 code E88.12
  • Laboratory evidence: Leptin levels (typically <4 ng/mL for generalized lipodystrophy)
  • Metabolic complications: HbA1c, lipid panels, liver function tests showing diabetes or dyslipidemia
  • Prior therapy records: Documentation of failed conventional treatments
  • Genetic testing: If available for congenital forms

REMS Documentation

REMS Program Requirements

The FDA requires Myalept to be dispensed through a Risk Evaluation and Mitigation Strategy (REMS) program due to risks of anti-metreleptin antibodies and lymphoma.

Prescriber Requirements

Pharmacy Requirements

  • Only REMS-certified specialty pharmacies can dispense Myalept
  • CVS Specialty is typically the preferred pharmacy for Aetna members

Patient Monitoring

  • Regular monitoring for neutralizing antibodies
  • Lymphoma screening per REMS protocol
  • Documentation of ongoing clinical benefit

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
Lack of generalized lipodystrophy diagnosis Provide specialist confirmation and genetic testing if available Clinical notes, photos, genetic results
Insufficient prior therapy documentation Submit detailed records of failed treatments Pharmacy records, clinic notes, lab results
REMS paperwork missing Complete enrollment and resubmit REMS forms, certification confirmations
Use for partial lipodystrophy Clarify diagnosis as generalized form Specialist letter, clinical findings
Medical necessity not established Provide metabolic complication evidence HbA1c, lipid panels, liver function tests
From our advocates: We've seen many Myalept denials overturned by providing comprehensive documentation of metabolic complications. Include trending lab values showing worsening diabetes or dyslipidemia despite optimal conventional therapy. This clearly demonstrates medical necessity beyond the diagnosis alone.
