CPT® Code 49622

Repair of parastomal hernia, any approach (ie, open, laparoscopic, robotic), initial or recurrent, including implantation of mesh or other prosthesis, when performed; incarcerated or strangulated

The CPT® Code 49622 refers to the surgical procedure for the repair of a parastomal hernia, which can be performed using various approaches, including open, laparoscopic, or robotic techniques. A parastomal hernia occurs when there is a bulging of bowel or other tissue through a defect surrounding an existing stoma, such as a colostomy. This condition can arise either initially or as a recurrence of a previous hernia. The procedure involves several critical steps, including the potential implantation of mesh or other prosthetic materials to reinforce the abdominal wall and prevent future herniation. The repair is particularly complex when the hernia is incarcerated or strangulated, meaning that the contents of the hernia sac cannot be easily returned to their normal position, and there may be a risk of necrotic tissue that requires surgical resection. The careful dissection of adhesions, identification of the hernia sac, and meticulous closure of the defect are essential components of this procedure to ensure optimal outcomes and minimize the risk of recurrence.
