Deep endometriosis of the right pelvic sidewall

This code signifies the presence of endometrial-like tissue infiltrating deeply into the right pelvic sidewall. This condition is characterized by the growth of endometrial glands and stroma outside the uterus, specifically affecting the muscular or connective tissues of the right lateral wall of the pelvis. It often leads to chronic pelvic pain, dyspareunia, and can impact organ function depending on the extent of infiltration.

Apply this code when documentation explicitly states deep infiltrating endometriosis affecting the right pelvic sidewall. This diagnosis is typically confirmed through imaging studies (e.g., MRI, transvaginal ultrasound) or direct visualization during laparoscopy with histological confirmation. Use this code when the laterality and depth of infiltration are clearly specified.

• Ensure documentation specifies "deep" endometriosis and the exact location as "right pelvic sidewall."
• Do not confuse with superficial endometriosis or endometriosis affecting other pelvic sites; laterality and depth are crucial for accurate coding.
• Consider sequencing this code with codes for associated symptoms (e.g., chronic pelvic pain) or complications, if applicable.
