Suprvsn of preg w poor reprodctv or obstet history, unsp tri

This code signifies the medical oversight of a pregnancy in a patient who has a documented history of adverse reproductive or obstetric outcomes, such as recurrent miscarriages, stillbirths, or other complications in previous pregnancies, but the specific trimester of the current pregnancy is not documented. It indicates that the pregnancy is being managed with heightened awareness due to past difficulties.

Apply this code when a pregnant patient is receiving antenatal care and their medical record explicitly states a history of poor reproductive or obstetric outcomes, but the current trimester is not specified. Documentation should clearly indicate the reason for increased surveillance due to this history.

• Ensure documentation specifies "unspecified trimester" if the trimester is not clearly stated. If the trimester is known, a more specific O09.2- code should be used.
• This code is for supervision only; it does not indicate a current complication. If a current complication exists, code it in addition to this supervision code.
• Always sequence this code as a secondary diagnosis, following the code for the current pregnancy status (e.g., Z34.-).
