Greater than 42 weeks gestation of pregnancy

This code signifies a pregnancy that has progressed beyond 42 completed weeks of gestation, indicating a post-term pregnancy. This extended duration increases the risk of certain maternal and fetal complications, necessitating close monitoring and potential intervention.

Assign this code when documentation explicitly states the pregnancy has exceeded 42 weeks of gestation. This is typically used in cases of labor induction for post-term pregnancy, or when managing complications arising from prolonged gestation.

• Ensure the documentation clearly specifies "greater than 42 weeks" or "post-term" with a gestational age exceeding 42 weeks.
• Do not use this code for pregnancies between 40 and 42 weeks (term pregnancies).
• Always sequence this code as a secondary diagnosis, following the code for the outcome of delivery (e.g., O80 for uncomplicated delivery).
