Chronic hepatitis, not elsewhere classified (K73)

The ICD-10 code section K73 covers types of chronic hepatitis that are not classified elsewhere, helping healthcare professionals identify long-term liver inflammation when it does not fit into other specific categories. These codes are essential for accurately diagnosing and documenting chronic liver conditions that persist over time.

This section includes several subcodes for more precise classification: K73.0 is used for chronic persistent hepatitis, indicating ongoing mild liver inflammation; K73.1 refers to chronic lobular hepatitis, involving inflammation focused in the liver lobules; and K73.2 denotes chronic active hepatitis, a more aggressive form with active liver damage. The code K73.8 is for other chronic hepatitis, such as lymphocytic portal hepatitis, while K73.9 is for unspecified or recurrent chronic hepatitis conditions, including those presenting with growth or developmental concerns. These distinctions assist medical coders in selecting the most accurate ICD-10 code for varied presentations of chronic hepatitis not caused by infectious agents.
