Deep endometriosis of the left pelvic brim

This code signifies the presence of deep infiltrating endometriosis specifically located at the left pelvic brim. Deep endometriosis involves infiltration of endometrial-like tissue greater than 5mm beneath the peritoneal surface, causing significant pain and potential organ dysfunction.

Apply this code when documentation clearly identifies deep endometriosis affecting the left pelvic brim, confirmed by imaging (e.g., MRI, transvaginal ultrasound) or surgical findings. This code is appropriate for patients presenting with chronic pelvic pain, dyspareunia, or other symptoms referable to this specific anatomical location.

• Ensure the documentation specifies "deep" endometriosis and the exact location as the "left pelvic brim."
• Do not confuse with superficial endometriosis or endometriosis in other pelvic locations; specific codes exist for those.
• Consider sequencing this code after codes for associated symptoms or complications, if applicable.
