Unspecified viral hepatitis (B19)

ICD-10 code B19 covers unspecified viral hepatitis, a category used when the exact type of viral hepatitis is unknown or not specified. This section includes conditions ranging from general viral hepatitis to specific forms accompanied by hepatic coma, a serious complication impacting brain function.

The codes in the B19 range are applied when providers document viral hepatitis without identifying the virus subtype, including codes for unspecified hepatitis B and C infections. Variations such as B19.0 and B19.11 specify cases where viral hepatitis leads to hepatic coma, a critical state often described in terms like "hepatic coma due to viral hepatitis B." In contrast, B19.10 and B19.20 describe viral hepatitis B and C without this severe complication, capturing conditions also known as "reactivation of hepatitis B viral hepatitis" or "viral hepatitis C complicating pregnancy." The general code B19.9 is used for unspecified viral hepatitis without hepatic coma and includes descriptions like "posttransfusion viral hepatitis" or "viral hepatitis complicating pregnancy and childbirth." These ICD-10 codes assist healthcare professionals and coders in accurately classifying cases where viral hepatitis is present but detailed viral identification is unavailable or unspecified.
