Deep endometriosis of bilateral uterosacral ligament(s)

This diagnosis code signifies the presence of deep infiltrating endometriosis affecting both uterosacral ligaments. This condition involves endometrial-like tissue growing more than 5mm beneath the peritoneal surface, specifically within these supportive pelvic structures. It often presents with severe pelvic pain, dyspareunia, and bowel or bladder symptoms due to nerve involvement and organ distortion.

This code is appropriate when diagnostic imaging (e.g., MRI, transvaginal ultrasound) or surgical findings confirm deep endometriotic implants in both uterosacral ligaments. It should be used to specify the anatomical location and depth of endometriosis when documented by a gynecologist or surgeon. Documentation should clearly indicate "deep" involvement and laterality.

• Ensure documentation explicitly states "deep" endometriosis and bilateral involvement of the uterosacral ligaments.
• Distinguish from superficial peritoneal endometriosis or endometriosis affecting other pelvic sites, which have different codes.
• Consider sequencing this code with codes for associated symptoms (e.g., chronic pelvic pain, dyspareunia) or complications, if applicable.
