  • ✅ Current patient age (must be 3-15 years for Hetlioz LQ)

Weight-Based Dosing and Billing Units

Hetlioz LQ requires precise weight-based dosing that affects both clinical appropriateness and billing accuracy:

Dosing Formula:

  • ≤28 kg: 0.7 mg/kg once daily
  • >28 kg: 20 mg once daily (fixed dose)
  • Concentration: 4 mg/mL oral suspension

Billing Conversion Examples:

  • 20 kg child: 0.7 × 20 = 14 mg = 3.5 mL daily
  • 30-day supply = 105 mL total
  • 30 kg child: 20 mg = 5 mL daily
  • 30-day supply = 150 mL total

Key Billing Points:

  • Bill by total mL dispensed, not mg or bottles
  • Use NDC format (commonly 69336-0317-53, verify with pharmacy)
  • Process under pharmacy benefit, not medical
  • Include exact weight and calculation in PA request
