ICD-10 codes for Hepatitis C
Hepatitis C is coded primarily under B18.2, B17.10, B17.11 in the ICD-10-CM (Clinical Modification) classification. Top-level categories include B17 (Other acute viral hepatitis); B18 (Chronic viral hepatitis); B19 (Unspecified viral hepatitis). The 2025 ICD-10-CM code set includes 23 codes related to hepatitis c, of which 17 are billable (specific enough to appear on a medical claim).
Hepatitis C is coded under B17.10 (acute, without hepatic coma), B17.11 (acute, with hepatic coma), B18.2 (chronic), and B19.20 / B19.21 (unspecified viral hepatitis C). B18.2 is the most commonly used code; sustained virologic response after treatment is coded with Z86.19 (personal history of other infectious diseases).
