Dosing — weight-banded IV (adult PNH/aHUS)

WeightLoading (Day 1)Maint. (Day 15, q8wk)

  • gMG / NMOSD (≥40 kg): identical weight-band schedule
  • Maintenance window ±7 days (except first maint at Day 15)
  • 1 unit = 10 mg — divide mg by 10 for J1303 units
  • Year-1 typical (75 kg PNH): 1 load + 7 maint = ~2,250 J1303 units
  • SC OnBody: 490 mg SC weekly via 2 cartridges (adult PNH only, FDA 3/2024)

ULTOMIRIS REMS — required

Separate enrollment from Soliris REMS — shared UltSolREMS.com portal but per-drug certification.

  • Phone: 1-888-765-4747 (Alexion / UltSol REMS)
  • Web: UltSolREMS.com
  • MenACWY + MenB per ACIP ≥2 wk before first dose (or antibacterial prophylaxis)
  • REMS Patient Safety Card carried during therapy + 8 months post-discontinuation
  • Prescriber + pharmacy + infusion site enrollment all required
Common error: using Soliris REMS cert for Ultomiris. Hard REMS violation → FDA notification + payer recoupment. Confirm separate ULTOMIRIS REMS enrollment.

JW reporting required and reimbursable when waste occurs. 100 mg waste = 10 JW units on a separate line. Failing to report JW is both compliance + revenue risk.

ICD-10

CodeIndication
D59.5PNH (Marchiafava-Micheli) — primary
D59.32Hereditary HUS / aHUS
D59.39Other HUS (commonly used for aHUS)
D59.31Shiga-toxin HUS — verify; generally NOT an Ultomiris indication
G70.00 / G70.01gMG (adults, anti-AChR+)
G36.0NMOSD (Devic's, adults, anti-AQP4+)
Bill the right ICD-10 for the indication. Using D59.5 (PNH) on a gMG claim triggers indication-mismatch denial.

Payer requirements (May 2026)

PayerPAPreference / UM
UnitedHealthcareYesCombined C5 inhibitor policy; Ultomiris preferred for new starts
Aetna (CPB)YesComplement inhibitor PA; HOPD steerage
Anthem / CarelonYesDrug.00086 (combined ravulizumab/eculizumab); Carelon UM
CignaYesMagellan Rx UM common
Many payers prefer Ultomiris over Soliris for new starts — q8wk eliminates ~20 infusions/year vs q2wk Soliris.
