Clinical Criteria Requirements
Diagnosis Confirmation
Cigna requires documented Type 1 Gaucher disease with:
- Enzyme deficiency: β-glucocerebrosidase activity <15% of normal range
 - Genetic testing: GBA1 gene mutation confirmation
 - Clinical manifestations: Evidence of organomegaly, cytopenia, or bone involvement
 - ICD-10 code: E75.22 (Gaucher disease)
 
No Step Therapy Requirements
Unlike some specialty medications, Cigna does not require step therapy for Cerezyme as first-line treatment for Type 1 Gaucher disease. This means you don't need to try and fail other therapies first.
Prescriber Requirements
- Must be prescribed by a specialist experienced in Gaucher disease
 - Typically hematologist, geneticist, or metabolic disease specialist
 - Provider must document expertise in enzyme replacement therapy
 
Coding and Billing Information
Essential Billing Codes
| Code Type | Value | Description |

| ICD-10 | E75.22 | Type 1 Gaucher disease | 
| CPT | 96365, 96366 | IV infusion administration | 
Unit Calculations
- Billing units: 1 unit of J1786 = 10 units of imiglucerase
