Coding Basics: Medical vs. Pharmacy Benefit

Myalept (metreleptin) is typically covered under the outpatient pharmacy benefit for self-administration at home. However, benefit assignment can vary by plan design.

Pharmacy Benefit Path:

  • Most common for Myalept
  • Requires pharmacy prior authorization
  • Managed by CVS Caremark for most Aetna plans
  • Uses NDC codes for billing

Medical Benefit Path:

  • Used when patient cannot self-administer
  • Requires medical prior authorization
  • Uses HCPCS J-codes for billing
  • Needs clinical justification for inability to self-inject
Tip: Always verify benefit assignment first by calling the member services number on the insurance card. This prevents delays and resubmissions.

ICD-10 Requirements for Coverage

The only covered diagnosis for Myalept is generalized lipodystrophy, coded as E88.12.

Coverage Requirements Table

Requirement Details Documentation Needed
Primary Diagnosis E88.12 (Generalized lipodystrophy) Clinical notes confirming generalized fat loss
Leptin Deficiency Must be documented Lab results or clinical assessment
Metabolic Complications Insulin resistance, diabetes, dyslipidemia HbA1c, lipid panels, glucose levels
Prior Therapies Conventional treatments attempted Records of failed/inadequate responses

Documentation Words That Support Coding

When documenting for E88.12, include these clinical descriptors:

  • "Generalized loss of subcutaneous fat"
  • "Congenital or acquired lipodystrophy"
  • "Severe insulin resistance"
  • "Leptin deficiency confirmed"
  • "Metabolic complications of lipodystrophy"

Important: Partial lipodystrophy (E88.11) or HIV-related lipodystrophy are not covered indications for Myalept.

Product Coding: HCPCS, NDC, and Units

Key Codes for Myalept

Code Type Code Description
HCPCS J3590 Unclassified biologics (for medical benefit)
NDC 66780-310-01 Myalept 11.3 mg vial
NDC 76431-210-01 Alternative NDC for same product

Dosing and Units Calculation

Critical: Myalept dosing must be calculated precisely to avoid billing errors.

Adult Dosing:

  • Men: 2.5 mg (0.5 mL/50 units)
  • Women: 5 mg (1.0 mL/100 units)
  • Maximum: 10 mg (2.0 mL/200 units) daily

Pediatric Dosing (≤40 kg):

  • Starting: 0.06 mg/kg daily
  • Increments: 0.02 mg/kg
  • Maximum: 0.13 mg/kg daily

Unit Conversion Formula

  1. Calculate mg dose based on weight/gender
  2. Convert to mL: mg ÷ 5 mg/mL = mL
  3. Convert to units: mL × 100 = units

Example: 2.5 mg dose = 0.5 mL = 50 units on insulin syringe

FAQ

Q: How long does Aetna CVS Health prior authorization take for Myalept? A: Standard decisions typically take 15-30 days. Expedited reviews for urgent cases can be completed within 72 hours.

Q: What if Myalept is not on Aetna's formulary? A: Request a formulary exception with medical necessity documentation. Rare disease drugs like Myalept often receive exceptions when properly justified.

Q: Can I appeal if I live in New Jersey but have an out-of-state employer plan? A: Self-insured employer plans follow federal ERISA rules, not New Jersey's IHCAP process. Contact your plan administrator for appeal procedures.

Q: Does step therapy apply to Myalept? A: Generally no, since there are no FDA-approved alternatives for generalized lipodystrophy. However, documentation of conventional therapy attempts may be required.

Q: What happens if I develop anti-metreleptin antibodies? A: This is a serious REMS-monitored risk. Contact your prescriber immediately and expect insurance to require updated clinical assessment for continued coverage.

Q: Can my doctor prescribe Myalept for partial lipodystrophy? A: No, Myalept is only FDA-approved for generalized lipodystrophy. Off-label use for partial lipodystrophy is not covered by insurance.
