30 weeks gestation of pregnancy

This code indicates that a pregnant patient has reached exactly 30 weeks of gestation. It is used to precisely document the gestational age of the fetus at a specific point in time during the pregnancy.

This code is appropriate for documenting the gestational age in obstetric records, particularly when the 30-week mark is significant for clinical management, scheduling of tests, or monitoring fetal development. It is used in conjunction with other codes describing the pregnancy's outcome or complications.

• Always use in conjunction with a code from category O09 (Supervision of high-risk pregnancy) or O09.A-O09.B (Supervision of normal pregnancy).
• Do not use if the gestational age is not precisely 30 weeks; select the appropriate Z3A.xx code for the exact week.
• This code is for documentation of gestational age only and does not indicate a complication or outcome of pregnancy.
