What are Hepatitis C ICD-10-CM Codes?
The ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) provides a standardized system for documenting and coding diseases. These codes are essential for accurate diagnosis, billing, and treatment, particularly for conditions like hepatitis C, a serious viral hepatitis that affects the liver and can lead to cirrhosis, hepatic failure, or subacute hepatic failure if left untreated.
ICD-10-CM includes several specific codes related to hepatitis C virus infection, distinguishing between acute, chronic, and unspecified viral hepatitis C, and also whether it presents with or without hepatic coma.
- B17.1 – Acute hepatitis C: Used for acute hepatitis C infection, typically within six months of exposure. Represents early-stage viral hepatitis and is considered billable.
- B18.2 – Chronic viral hepatitis C: Used when the infection becomes long-term or chronic hepatitis. Often seen in patients with a history of intravenous drug abuse or contaminated blood parenterally.
- Z22.52 – Carrier of viral hepatitis C: Indicates a silent carrier state with no active symptoms but persistent hepatitis C virus presence. Applies to patients with no signs of acute or chronic symptoms.
- B19.20 – Unspecified viral hepatitis C without hepatic coma: Used when clinical details are lacking and the case is categorized as unspecified viral hepatitis C without hepatic coma. Applies to cases of hepatitis C without hepatic symptoms like coma.
- B19.21 – Unspecified viral hepatitis C with hepatic coma: Used for hepatitis C infection when documentation includes hepatic coma but doesn’t specify whether it’s acute or chronic.
