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.

Prescriber Requirements
- Complete REMS training module
- Submit Prescriber Enrollment Form
- Use REMS Prescription Authorization Form for each prescription
Pharmacy Requirements
- Only REMS-certified specialty pharmacies can dispense Myalept

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.
