10 weeks gestation of pregnancy

This code signifies a pregnancy that has reached precisely 10 completed weeks of gestation. It is used to document the gestational age of the fetus, which is crucial for monitoring fetal development and planning prenatal care.

This code is appropriate when a patient is confirmed to be 10 weeks pregnant, typically based on the last menstrual period (LMP) or early ultrasound measurements. It is commonly used during initial prenatal visits or subsequent encounters where gestational age is updated or confirmed.

• Always confirm the gestational age with the physician's documentation, typically from the LMP or ultrasound.
• Do not use this code if the gestational age is not precisely 10 weeks; select the appropriate Z3A.xx code.
• This code is often used in conjunction with other codes describing the reason for the encounter (e.g., routine prenatal care, complications of pregnancy).
