Superficial endometriosis of left ovary

This code signifies the presence of endometrial tissue on the surface of the left ovary. This ectopic tissue behaves similarly to normal uterine lining, causing inflammation, pain, and potentially impacting fertility. It represents a specific anatomical location and depth of endometriosis.

Use this code when documentation explicitly states superficial endometriosis affecting the left ovary, typically confirmed during laparoscopic examination or imaging. This diagnosis is often made in patients presenting with chronic pelvic pain, dysmenorrhea, or infertility. Supporting documentation should clearly identify the affected ovary and the superficial nature of the endometrial implants.

• Differentiate from deep infiltrating endometriosis, which has distinct codes.
• Ensure laterality is clearly documented (left vs. right vs. bilateral).
• Code additional sites of endometriosis if present, following sequencing guidelines.
