CPT® Code 49621

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

The CPT® Code 49621 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 is characterized by the protrusion of bowel or other tissue through a defect that forms around an existing stoma, such as a colostomy. This condition can occur either initially or as a recurrence after previous surgical intervention. The procedure involves several critical steps, including the identification and dissection of adhesions, the excision of the hernia sac, and the careful closure of the defect to prevent future herniation. Additionally, the implantation of mesh or other prosthetic materials is often utilized to reinforce the abdominal wall and support the stoma, ensuring that the opening remains adequately sized to prevent complications while maintaining the integrity of the surrounding tissue. The procedure is designed to be thorough, addressing both the immediate repair of the hernia and the long-term prevention of recurrence.
