Maternal care for viable fetus in abd preg, unsp tri, unsp

This code signifies ongoing maternal medical supervision for a fetus confirmed to be alive and developing within the abdominal cavity, outside of the uterus. It indicates that the specific trimester of the pregnancy is either unknown or not documented.

Apply this code when documentation confirms an abdominal pregnancy with a viable fetus, but the gestational age or trimester is not specified. This is typically used for initial encounters or when complete gestational dating is unavailable. Documentation should clearly state "abdominal pregnancy" and "viable fetus."

• Do not use this code if the trimester is known; instead, select the trimester-specific code (O36.71-, O36.72-, O36.73-).
• This code is for maternal care of the viable fetus; use other codes for non-viable or ectopic pregnancies not in the abdomen.
• Ensure documentation explicitly states "abdominal pregnancy" and "viable fetus" to support this code.
