38 weeks gestation of pregnancy

This code indicates that a pregnancy has reached a gestational age of 38 completed weeks. It signifies a full-term pregnancy, typically within the window where delivery is expected.

This code is used to specify the exact gestational age of a pregnancy at the time of an encounter. It is frequently applied during prenatal visits, labor and delivery admissions, or when documenting the status of a pregnancy nearing its expected due date.

• Always use in conjunction with a code from category O09 (Supervision of high-risk pregnancy) or Z3A (Gestational age).
• Ensure the gestational age is accurately documented by the provider, typically based on the last menstrual period (LMP) or ultrasound.
• Do not use for postpartum encounters; this code is specific to the gestational age during pregnancy.
