Suprvsn of preg w insufficient antenat care, second tri

This code signifies a pregnancy where the patient is in her second trimester and has received inadequate prenatal care. This typically means fewer than the recommended number of antenatal visits, or a lack of essential screenings and assessments during this critical period of gestation.

Apply this code when documentation indicates a pregnant patient in her second trimester has not engaged in sufficient antenatal care, as determined by clinical guidelines or physician assessment. This could be due to late presentation for care, missed appointments, or limited access to healthcare services.

• Always assign an additional code from category Z3A to specify the weeks of gestation.
• Ensure the medical record clearly documents the patient's trimester and the specific reasons for insufficient antenatal care.
• Distinguish from O09.30 (unspecified trimester) and O09.31 (first trimester) based on documented gestational age.
