K40: Inguinal hernia

K40.9: Unilateral or unspecified inguinal hernia, without obstruction or gangrene

An inguinal hernia, which is classified under code K40.9 in the ICD-10, exists when part of the intestine or fat pushes through a weak area in the lower abdominal wall, specifically into the inguinal canal in the groin area. This condition can occur on one side (unilateral) or it might not be specified which side it is on. Symptoms can vary in severity but commonly include a noticeable bulge on either side of the pubic bone, discomfort or pain in the groin area, and a feeling of weakness or pressure in the groin. Despite the potential discomfort, the specific condition identified by code K40.9 indicates that this form of inguinal hernia is without obstruction or gangrene, meaning that there is no blockage in the intestines and no tissue has died as a result of insufficient blood flow.
