17 weeks gestation of pregnancy

This code indicates that a patient is precisely 17 weeks into their pregnancy. It is used to specify the gestational age, which is crucial for monitoring fetal development and managing pregnancy-related care.

This code is used when documenting the gestational age of a pregnant patient at 17 weeks. It is typically applied during routine prenatal visits, for diagnostic testing, or when managing any pregnancy-related conditions where the exact week of gestation is clinically relevant.

• Always confirm the gestational age from the physician's documentation, typically based on the last menstrual period (LMP) or ultrasound.
• This code is a secondary code and should always be reported in conjunction with a primary code indicating the reason for the encounter or the pregnancy itself (e.g., O09.-, Z34.-).
• Ensure the gestational week documented matches the specific Z3A.- code selected.
