In simple words: This code describes a condition where tissue from the inside of the uterus grows in the sigmoid colon (part of the large intestine).This can be painful and affect bowel movements.

N80.522, Deep endometriosis of the sigmoid colon, signifies the presence of endometrial tissue (tissue normally lining the uterus) in the sigmoid colon, characterized by its deep infiltration into the bowel wall. This condition can cause significant pain, bowel dysfunction, and other complications.

Example 1: A 35-year-old female presents with chronic pelvic pain and bowel changes, including constipation and rectal bleeding.Imaging reveals deep endometriosis involving the sigmoid colon., A 40-year-old female undergoes laparoscopic surgery for suspected endometriosis. During the procedure, deep infiltrating endometriosis is found in the sigmoid colon requiring resection of the involved bowel segment., A 28-year-old female with a history of endometriosis experiences worsening symptoms of dysmenorrhea (painful menstruation) and bowel obstruction. Colonoscopy demonstrates a large mass in the sigmoid colon consistent with deep endometriosis.

Detailed history and physical examination, imaging studies (ultrasound, MRI, CT scan), operative reports (if surgery performed), pathology reports (if tissue biopsy obtained), and documentation of symptoms and response to treatment are essential.

** Deep endometriosis of the sigmoid colon can be a complex condition requiring multidisciplinary management.Accurate coding requires detailed clinical documentation to ensure appropriate reimbursement.
