Superficial endometriosis of the left uterosacral ligament

This code signifies the presence of endometrial-like tissue growing superficially on the left uterosacral ligament, a fibrous band connecting the uterus to the sacrum. This ectopic tissue can cause localized inflammation, pain, and scarring. It specifically denotes a non-deeply infiltrative form of endometriosis affecting this particular anatomical structure.

Use this code when documentation clearly indicates superficial endometriosis confirmed to be located on the left uterosacral ligament. This diagnosis is often made during laparoscopic examination or other surgical procedures where direct visualization and/or biopsy confirms the lesion's location and superficial nature. Supporting documentation should specify the laterality and the ligament involved.

• Ensure documentation specifies "superficial" and "left uterosacral ligament" to accurately assign this code.
• Distinguish from deep infiltrating endometriosis (DIE) of the uterosacral ligament, which has different codes.
• Do not use if the laterality or specific ligament is not documented; consider N80.30 for unspecified uterosacral ligament endometriosis.
