Umbilical hernia (K42)

ICD-10 code K42 covers diagnoses related to an umbilical hernia, a condition where tissue pushes through the abdominal muscles near the navel. These codes specify whether the hernia is uncomplicated, obstructed, or complicated by gangrene.

This section includes K42.9 for umbilical hernias without obstruction or gangrene, commonly described as a reducible or protruding umbilicus. The code K42.0 is used when the hernia causes intestinal obstruction without tissue death, also referred to by synonyms such as obstructed or strangulated umbilical hernia. For cases where tissue death occurs, called gangrene, the correct code is K42.1, which covers paraumbilical hernias with gangrene, including conditions sometimes known as congenital omphalocele with gangrene. Using these specific ICD-10 codes ensures precise documentation and coding of various umbilical hernia presentations, helping healthcare providers accurately capture the severity and complications involved.
