Maternal care for viable fetus in abd preg, second tri, oth

This code signifies medical supervision and management provided to a pregnant patient carrying a viable fetus located outside the uterus within the abdominal cavity, specifically during the second trimester of gestation. It indicates that there are other fetuses present in addition to the one in the abdominal pregnancy.

Apply this code when documentation clearly indicates an abdominal pregnancy with a viable fetus, the pregnancy is in the second trimester, and there are other fetuses (e.g., an intrauterine twin). Supporting documentation includes ultrasound reports confirming fetal viability and location, and physician notes detailing the management of this high-risk pregnancy.

• Ensure documentation specifies "viable fetus" and "second trimester" for accurate code assignment.
• Distinguish from O36.71- (first trimester) and O36.73- (third trimester) based on gestational age.
• Always sequence this code as a primary diagnosis when the abdominal pregnancy is the focus of care, followed by codes for any associated complications.
