Hernia (K40-K46)

ICD-10 codes K40-K46 cover various types of hernias, including inguinal, femoral, umbilical, ventral, diaphragmatic, and other abdominal hernias. These codes specify details like whether the hernia is bilateral or unilateral, if there is obstruction, gangrene, or if the hernia is recurrent.

This code range is used to classify and document different hernia conditions with precision. For example, K40 refers to inguinal hernias, including subtypes such as irreducible or obstructed bilateral inguinal hernia. Codes like K41 relate to femoral hernias, often described with terms like Béclard's hernia or Cloquet's hernia. Umbilical hernias (K42) include terms like paraumbilical hernia. Ventral hernias (K43) may involve incisional or parastomal hernias, while diaphragmatic hernias (K44) cover hiatal and paraesophageal types. The detailed subclassifications (such as with or without gangrene or obstruction) help healthcare providers accurately document severity and recurrence, facilitating appropriate treatment planning and billing.
