Document meningococcal immunization at least 2 weeks prior to the first eculizumab dose or a clinical justification that delaying eculizumab posed greater risk than meningococcal infection.
For PNH initiation, document flow cytometry confirming PNH and either evidence of clinically significant hemolysis or a documented history of a major adverse vascular event (MAVE) from thromboembolism.
For aHUS initial trial, document absence of signs of STEC-HUS and that TTP was ruled out (e.g., normal ADAMTS13 activity and no inhibitor), or document a plasma exchange trial that failed to produce clinical improvement.
If continuing eculizumab after the aHUS initial trial, document clinical improvement such as increased platelet count or laboratory evidence of reduced hemolysis.

Eculizumab is covered for treatment of paroxysmal nocturnal hemoglobinuria (PNH) when flow cytometry confirms PNH and there is either evidence of clinically significant hemolysis or a documented history of a major adverse vascular event (MAVE) from thromboembolism.
Eculizumab is covered for treatment of atypical hemolytic uremic syndrome (aHUS) as an initial trial (generally 6–12 weeks) when the individual has no signs of STEC-HUS and thrombotic thrombocytopenic purpura (TTP) has been ruled out or a trial of plasma exchange did not produce clinical improvement.
Eculizumab is covered for biopsy-proven dense deposit disease when elevated serum sC5b-9 (sMAC) levels are documented.
Eculizumab may be covered for other label and off-label indications supported by recognized compendia or the FDA label when dose and frequency conform to FDA labeling or recognized compendia guidance.
Anti-neoplastic (chemotherapy) agent CPT/HCPCS codes may be used to bill for administration of these drugs when given to treat non-oncologic (noncancer) diagnoses if the drug is medically necessary for the patient’s condition and consistent with the standard of medical practice.
Monoclonal antibody agents and other biologic response modifiers may be administered and billed using chemotherapy administration codes for noncancer indications when the dose, route, and clinical use are appropriate and medically necessary.
