Left ovarian pregnancy with intrauterine pregnancy

This diagnosis code indicates a rare and complex form of heterotopic pregnancy where a viable or non-viable pregnancy is located in the left ovary concurrently with a separate intrauterine pregnancy. This condition involves two distinct gestations occurring simultaneously in different locations.

Apply this code when documentation clearly specifies a confirmed left ovarian pregnancy coexisting with an intrauterine pregnancy. This typically follows ultrasound confirmation and may be identified during evaluation for abdominal pain, vaginal bleeding, or during routine prenatal care.

• Ensure documentation explicitly states "left ovarian" involvement; otherwise, an unspecified ovarian pregnancy code may be more appropriate.
• Always code the intrauterine pregnancy separately using the appropriate Z3A code for gestational age.
• Consider additional codes for complications such as rupture, hemorrhage, or fetal demise, if documented.
