B18.2

Chronic viral hepatitis C

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/05/2025

Code Description

ICD-10 B18.2 is a billable code used to indicate a diagnosis of chronic viral hepatitis c.

Key Diagnostic Point:

Chronic viral hepatitis C is a long-term infection of the liver caused by the hepatitis C virus (HCV). This condition can lead to significant liver damage over time, including cirrhosis and liver cancer. HCV is primarily transmitted through blood-to-blood contact, which can occur through sharing needles, receiving contaminated blood products, or from mother to child during childbirth. Many individuals with chronic hepatitis C may remain asymptomatic for years, making early detection and management crucial. Chronic hepatitis C can lead to various complications, including liver fibrosis, portal hypertension, and hepatocellular carcinoma. Management typically involves antiviral therapy aimed at achieving a sustained virologic response (SVR), which indicates that the virus is no longer detectable in the blood. Regular monitoring of liver function and screening for liver cancer are also essential components of chronic hepatitis C management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of HCV genotypes requiring specific treatment protocols
  • Need for ongoing monitoring and management of liver complications
  • Potential for co-infections with other viruses (e.g., HIV, HBV)
  • Variability in patient presentation and symptomatology

Audit Risk Factors

  • Inadequate documentation of HCV genotype and treatment history
  • Failure to document liver function tests and monitoring
  • Misclassification of acute vs. chronic hepatitis C
  • Lack of documentation for co-existing conditions

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of chronic hepatitis C, improving the ability to track treatment outcomes and complications. This specificity aids in better resource allocation and management strategies.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of chronic hepatitis C, improving the ability to track treatment outcomes and complications. This specificity aids in better resource allocation and management strategies.

Reimbursement & Billing Impact

Frequently Asked Questions

What is the difference between acute and chronic hepatitis C?

Acute hepatitis C is a short-term infection that may resolve on its own, while chronic hepatitis C persists for more than six months and can lead to serious liver complications.
