Other ectopic pregnancy with intrauterine pregnancy

This code signifies a rare and complex pregnancy where an ectopic pregnancy (implantation outside the uterus) coexists with a viable intrauterine pregnancy. This condition, known as a heterotopic pregnancy, presents significant risks to both the mother and the intrauterine fetus.

Apply this code when documentation clearly indicates the simultaneous presence of an ectopic gestation and an intrauterine pregnancy. This typically involves ultrasound confirmation of both locations. Use this code for cases where the ectopic pregnancy is located anywhere other than the fallopian tube, ovary, or abdomen.

• Always confirm the specific location of the ectopic pregnancy; if it's tubal, ovarian, or abdominal, a more specific O00 subcategory should be used.
• Ensure documentation explicitly states the presence of both an ectopic and an intrauterine pregnancy.
• Sequence this code as the primary diagnosis when the heterotopic pregnancy is the reason for the encounter, followed by codes for any associated complications.
