31 weeks gestation of pregnancy

This code indicates that a pregnancy has reached a gestational age of exactly 31 weeks. It is used to precisely document the duration of a pregnancy at a specific point in time, typically during an encounter or admission. This information is crucial for monitoring fetal development and planning appropriate prenatal care.

This code is used when the patient's pregnancy is determined to be 31 weeks gestation, often based on the last menstrual period (LMP) or ultrasound measurements. It is frequently applied during routine prenatal visits, hospital admissions for pregnancy-related conditions, or when assessing fetal viability and maturity.

• Always confirm the gestational age with the physician's documentation, typically from the LMP or ultrasound.
• This code is a secondary diagnosis and should be reported in conjunction with a primary code describing the reason for the encounter (e.g., routine prenatal care, complications of pregnancy).
• Do not use this code if the documentation indicates a range of weeks (e.g., "30-32 weeks"); seek clarification for a precise week.
