Matern care for viable fetus in abd preg, third tri, fetus 4

This code signifies ongoing maternal care for a pregnancy where a viable fetus is developing outside the uterus, specifically within the abdominal cavity, during the third trimester. It indicates that the pregnancy has progressed to the point where the fetus is considered viable, and the mother is receiving specialized management for this high-risk condition.

Use this code when documentation confirms an abdominal pregnancy with a viable fetus in the third trimester. This typically involves imaging studies (e.g., ultrasound, MRI) confirming the extrauterine implantation and fetal viability, along with physician notes detailing ongoing maternal care and monitoring for this specific gestational period.

• Ensure documentation explicitly states "abdominal pregnancy" and "third trimester."
• Verify fetal viability is documented; if not, a different subcategory may be more appropriate.
• Always sequence this code as a secondary diagnosis when reporting the primary reason for the encounter (e.g., routine prenatal visit, complications of pregnancy).
