Suprvsn of preg w insufficient antenat care, first trimester

This code signifies a pregnancy in its first trimester where the expectant mother has received inadequate or no prenatal care. This lack of sufficient antenatal services may pose risks to both maternal and fetal health due to missed screenings, counseling, and early identification of potential complications.

Apply this code when documentation indicates a pregnant patient in her first trimester has not received the recommended frequency or scope of prenatal care. This includes situations where the patient presents late for their first prenatal visit, or has missed scheduled appointments without adequate follow-up. Documentation should explicitly state the insufficiency of care during this specific gestational period.

• Ensure the documentation clearly specifies the first trimester of pregnancy.
• Distinguish from codes for insufficient care in later trimesters (O09.32- and O09.33-).
• Always sequence this code as a secondary diagnosis, following the code for the current pregnancy status (e.g., Z3A.00 for unspecified weeks of gestation).
