14 weeks gestation of pregnancy

This code signifies that a pregnant patient is precisely at the 14-week mark of her gestation period. It is a specific indicator of the duration of the pregnancy, typically calculated from the first day of the last menstrual period (LMP) or confirmed by ultrasound. This stage is part of the first trimester, moving into the second.

Apply this code when documenting the gestational age of a pregnancy, particularly during routine prenatal visits, initial assessments, or when a specific gestational age is required for clinical decision-making or billing purposes. It is used when the provider explicitly states or confirms the pregnancy is at 14 weeks.

• Always use in conjunction with a code from category O09 (Supervision of high-risk pregnancy) or Z3A (Gestational age) as a secondary diagnosis.
• Ensure the documentation clearly states "14 weeks gestation" or equivalent for accurate code assignment.
• Do not use if the gestational age is estimated to be 14 weeks and X days; use the appropriate code for 14 weeks if the exact day count is not specified.
