Superficial endometriosis of the right uterosacral ligament

This code identifies the presence of endometrial tissue abnormally located on the surface of the right uterosacral ligament. This condition is a form of endometriosis, characterized by the growth of tissue similar to the uterine lining outside the uterus, specifically affecting one of the primary pelvic support structures.

Apply this code when documentation explicitly states superficial endometriosis involving the right uterosacral ligament. This diagnosis is typically made during laparoscopic examination or other surgical procedures where the pelvic organs are directly visualized. Supporting documentation should include operative reports or pathology findings confirming the location and superficial nature of the endometrial implants.

• Ensure the documentation specifies "superficial" and the "right" uterosacral ligament; laterality and depth are crucial for accurate coding.
• Distinguish from deep infiltrating endometriosis (DIE) which involves invasion into the retroperitoneal space or organ walls.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting patient care.
