Initial Therapy - Medically Necessary Criteria

Continuation Therapy - Medically Necessary Criteria

Medically Necessary - Continuation of Therapy

For continuation of therapy, ALL of the following must be documented:

ALL of the following

Documentation of positive clinical response to therapy (e.g., increase in hemoglobin, decreased transfusion requirements, decreased markers of hemolysis, improvement in anemia-related symptoms)
Enjaymo is prescribed by, or in consultation with, a hematologist
Enjaymo dosing is in accordance with the United States Food and Drug Administration approved labeling
ALL of the following

Concomitant Complement Inhibitor Exclusion

Exclusion: Patients must not receive Enjaymo in combination with a complement inhibitor. Examples listed in the policy include: Empaveli (pegcetacoplan), Fabhalta (iptacopan), PiaSky (crovalimab), Soliris (eculizumab), Ultomiris (ravulizumab-cwzb), Zilbrysq (zilucoplan). Note: the policy was updated effective 04/01/2025 to expand the examples of excluded concomitant complement inhibitors to include PiaSky (crovalimab).

Denial Risk

Concomitant complement inhibitor exclusion

Claims may be denied if patient is receiving Enjaymo in combination with listed complement inhibitors (e.g., pegcetacoplan, iptacopan, crovalimab, eculizumab, ravulizumab-cwzb, zilucoplan).

Provider Requirements & Billing Rules

Prior Authorization

Prior authorization required for initial and continuation therapy

Initial and reauthorization approvals are limited to no more than 12 months. Documentation must show diagnosis confirmation, hematologist involvement, FDA-consistent dosing, absence of concomitant complement inhibitors, and for continuation evidence of clinical response.

J1302
D59.12

Documentation Required

Diagnostic confirmation and specialist involvement required

Require documentation of chronic hemolysis markers, positive polyspecific DAT, positive monospecific DAT for C3d, IgG DAT ≤ 1+, cold agglutinin titer ≥ 64 at 4°C, and that diagnosis was by or in consultation with a hematologist.

Clinical Evidence Supporting Use

Background evidence: Cold agglutinin disease (CAD) is an autoimmune hemolytic anemia in which cold agglutinins bind red blood cells and activate the classical complement pathway leading to primarily complement-mediated extravascular hemolysis. Sutimlimab (Enjaymo) is a classical complement C1s inhibitor given IV (loading doses on Days 0 and 7, then biweekly) that blocks classical pathway activation. Phase 3 evidence includes the single-arm CARDINAL study (n=24) showing a primary composite response in 54.2% of patients with a mean hemoglobin increase of 3.2 g/dL, rapid Hb rises of 1.2 g/dL by Week 1 and 2.3 g/dL by Week 3, and transfusion avoidance in 70.8% of patients from Weeks 5–26. The randomized placebo-controlled CADENZA trial demonstrated a responder rate of 72.7% with Enjaymo vs 15% with placebo (treatment difference 58.78, 95% CI: 34.6, 82.96; p = 0.0004).

Background & Definitions

Additional background/context: CAD is mediated by cold agglutinins that agglutinate RBCs at low temperatures and recruit classical complement components (C1, C4, C2) leading to C3b deposition and extravascular hemolysis by hepatic macrophages. Diagnosis relies on markers of chronic hemolysis, a positive polyspecific DAT with monospecific C3d, and cold agglutinin titer thresholds; treatment goals include improvement in hemoglobin and symptom relief.

Term	Definition
CAD	Cold agglutinin disease, a form of autoimmune hemolytic anemia mediated by cold agglutinins and complement.
DAT	Direct antiglobin test (Coombs test); polyspecific and monospecific for C3d are required as diagnostic criteria.
