Coverage Overview: Medical vs. Pharmacy Benefit

Soliris (eculizumab) is covered under Humana Medicare Part B as a medical benefit, not Part D pharmacy coverage. This is because it's administered by healthcare professionals via IV infusion and is not self-administered.

Coverage Requirements Table

Requirement Details Source
Prior Authorization Required for all indications Humana Provider Portal
FDA-Approved Uses PNH, aHUS, gMG, NMOSD FDA Label
Vaccination Proof Meningococcal vaccine ≥2 weeks prior FDA Safety Requirements
Specialist Requirement Typically hematologist or neurologist Humana Medical Policy
Site of Care Outpatient infusion center or hospital Part B Guidelines
Note: Humana's Medicare Advantage prior authorization denial rate is approximately 3.5% (2023), among the lowest of major insurers, but denials often stem from incomplete documentation.

HCPCS Billing Codes and Unit Calculations

Critical Billing Code Change (Effective April 1, 2025)

Code Description Unit Conversion Status
J1299 Injection, eculizumab, 2 mg 1 unit = 2 mg Current (April 2025+)
J1300 Injection, eculizumab, 10 mg 1 unit = 10 mg Discontinued

Dosing Calculation Examples

Patient Dose J1299 Units Calculation
300 mg 150 units 300 ÷ 2 = 150
900 mg 450 units 900 ÷ 2 = 450
1200 mg 600 units 1200 ÷ 2 = 600

Required Modifiers

  • JZ: Zero drug amount discarded
  • RE: REMS compliance (when applicable)
Critical: Unit conversion errors are the leading cause of Soliris billing problems. Always divide total mg by 2 for J1299 units.

From Our Advocates: We've seen cases where patients received approval after initially being denied for "insufficient diagnostic confirmation." The key was working with the specialist to provide additional antibody testing results and a detailed letter explaining why the patient met diagnostic criteria. While every case is different, thorough documentation often makes the difference between approval and denial.
