How to Use This Guide

This decision tree helps patients and clinicians navigate Aetna CVS Health's prior authorization process for Kanuma (sebelipase alfa) in New Jersey. Start with the eligibility triage below to determine your next steps.

Important: Kanuma is the only FDA-approved enzyme replacement therapy for lysosomal acid lipase deficiency (LAL-D). There are no therapeutic alternatives, which strengthens your case for coverage when properly documented.

Eligibility Triage: Do You Qualify?

✅ Likely Eligible if you have:

  • Confirmed LAL enzyme deficiency (activity <1.5 nmol/h/mL or below lab normal range)
  • Genetic confirmation with pathogenic LIPA variants
  • Clinical evidence: hepatomegaly, elevated ALT/AST (>1.5x ULN), dyslipidemia unresponsive to standard therapy
  • Age-appropriate dosing plan (infants: 1-3 mg/kg weekly; children/adults: 1 mg/kg every 2 weeks)

⚠️ Possibly Eligible if you have:

  • Strong clinical suspicion (≥3 criteria: hepatomegaly, elevated liver enzymes, dyslipidemia, low HDL-C <50 mg/dL, BMI <30 kg/m²)
  • Enzyme testing ordered but results pending
  • Genetic testing in progress
  • Family history of LAL-D with suggestive symptoms

❌ Not Yet if you have:

  • Only clinical symptoms without enzyme confirmation
  • Normal LAL enzyme activity
  • No genetic testing completed
  • Denial based on dosing outside FDA label parameters

If "Likely Eligible": Your Documentation Checklist

Submit your prior authorization through Aetna's Availity portal at least 2 weeks before planned treatment start.

Required Clinical Documentation:

  • LAL enzyme activity test results from accredited lab (Mayo Clinic Labs, Archimedlife, or equivalent)
  • LIPA genetic testing showing pathogenic variants
  • Diagnosis confirmation with ICD-10 code E75.5 (other lipidoses)
  • Clinical history documenting hepatomegaly, dyslipidemia, elevated liver enzymes
  • Prior treatment attempts and failures (if applicable)
  • Dosing justification based on age, weight, and FDA labeling

Submission Process:

  1. Primary method: Availity provider portal (includes Novologix for specialty drugs)
  2. Alternative fax: Specialty PA to 1-866-249-155
  3. Mail backup: Medical Exception Unit, 1300 East Campbell Road, Richardson, TX 75081
Tip: Include a medical necessity letter addressing Aetna's specific criteria and emphasizing that Kanuma is the only FDA-approved treatment for LAL-D.

If "Possibly Eligible": Tests to Request

Step 1: Order LAL Enzyme Activity Testing

  • Test type: Dried blood spot (DBS) or EDTA whole blood
  • Labs offering: Mayo Clinic Labs, Archimedlife
  • Normal range: 0.59-2.40 nmol/punch/h (varies by lab)
  • Timeline: Results typically within 5-7 business days

Step 2: Genetic Confirmation

  • Test: LIPA gene sequencing for pathogenic variants
  • When to order: After low enzyme activity confirmed
  • Insurance note: Most payers cover genetic testing when enzyme deficiency is documented

Step 3: Clinical Documentation

Track and document:

  • Liver function tests (ALT, AST, bilirubin)
  • Lipid panel (total cholesterol, LDL-C, HDL-C, triglycerides)
  • Response to lipid-lowering medications (if tried)
  • Imaging showing hepatomegaly or steatosis

Re-apply timeline: Submit PA within 30 days of receiving confirmatory test results.

If "Not Yet": Alternative Approaches

Exception Request Strategy

If you don't meet standard criteria but have compelling clinical need:

  1. Request formulary exception through Aetna's standard process
  2. Document medical necessity with:
    • Severity of clinical presentation
    • Risk of disease progression without treatment
    • Lack of therapeutic alternatives
  3. Include supporting literature from FDA labeling and peer-reviewed studies

Supportive Management Documentation

While gathering diagnostic confirmation:

  • Document trial and failure of supportive therapies (statins, dietary management)
  • Track disease progression markers
  • Note any contraindications to standard lipid management
