K40: Inguinal hernia

K40.3: Unilateral or unspecified inguinal hernia, with obstruction, without gangrene

The medical condition coded as K40.3 in ICD-10 WHO 2016 classification is an "Unilateral or unspecified inguinal hernia, with obstruction, without gangrene". Unilateral indicates that the condition occurs on one side of the body, while unspecified means it is not clearly defined whether it is on the left or right side. An inguinal hernia refers to a condition where a part of the intestine or abdominal fatty tissue bulges through a weakened area in the abdominal muscles. The term "with obstruction" signifies there is a blockage in the intestine due to the hernia. This blockage can lead to symptoms such as severe pain, nausea, vomiting, and the inability to pass gas. No gangrene means that despite this obstruction, there are no dead or decaying tissues, often a complication of loss of blood supply, associated with the condition.
