Left ovarian pregnancy without intrauterine pregnancy

This code signifies an ectopic pregnancy specifically located in the left ovary, where there is no co-existing pregnancy within the uterus. It represents a rare but serious form of ectopic gestation, posing significant risks to maternal health.

Apply this code when documentation clearly indicates a confirmed pregnancy implanted in the left ovary, and imaging or clinical findings rule out an intrauterine pregnancy. This typically occurs after surgical confirmation or definitive ultrasound findings.

• Ensure documentation explicitly states "left ovarian" and "without intrauterine pregnancy."
• Do not confuse with other ectopic sites (e.g., fallopian tube, abdominal) or heterotopic pregnancy (ectopic and intrauterine co-existing).
• Sequence this code as the primary diagnosis when it is the reason for the encounter.
