Late pregnancy (O48)

The ICD-10 code O48 covers conditions related to late pregnancy, including pregnancies that extend beyond the typical gestation period. This section specifically identifies issues like post-term and prolonged pregnancies.

Codes under O48 are used to document pregnancies lasting longer than usual, which can carry higher risks for both mother and baby. O48.0 is the code for post-term pregnancy, also known as post-term delivery, post-term pregnancy of 40 to 42 weeks, baby overdue, describing pregnancies that go past 40 weeks but are less than 42 weeks. The related O48.1 code covers prolonged pregnancy, sometimes called postmaturity of fetus, referring to conditions where the pregnancy extends even beyond this timeframe. These ICD-10-CM codes help healthcare providers accurately record and manage the care of pregnancies exceeding the expected duration, improving treatment planning and monitoring of outcomes.
