42 weeks gestation of pregnancy

This code indicates that a pregnancy has reached 42 completed weeks of gestation. This gestational age is considered post-term, meaning the pregnancy has extended beyond the typical 40-week duration. Post-term pregnancies can carry increased risks for both the mother and the fetus.

This code is used when documenting the gestational age of a pregnancy that has reached 42 weeks. It is typically applied in the context of labor and delivery, antenatal care for prolonged pregnancies, or when managing complications associated with being post-term. It helps to classify the pregnancy's duration for clinical management and statistical purposes.

• Always confirm the gestational age based on the most accurate dating method available in the medical record.
• This code is typically a secondary diagnosis, accompanying codes for the pregnancy itself (e.g., from category O09).
• Do not use this code if the pregnancy is still ongoing and has not yet reached 42 full weeks.
