Maternal care for damage to fetus by drugs, fetus 1

This code signifies maternal care provided when there is a suspected or confirmed adverse effect on the fetus due to the mother's use of drugs, medications, or other chemical substances. It specifically indicates that the fetus is a singleton pregnancy. The damage can manifest as congenital anomalies, growth restriction, or other developmental issues.

Apply this code when a pregnant patient is receiving monitoring or intervention due to exposure to teratogenic or fetotoxic drugs, whether prescribed, illicit, or accidental. Documentation should clearly state the maternal drug exposure and the suspected or observed impact on the fetus, such as fetal anomalies noted on ultrasound or concerns about fetal development.

• Always sequence this code as a secondary diagnosis, following the primary obstetric complication or condition.
• Ensure documentation specifies the type of drug involved for potential additional coding (e.g., T-codes for drug toxicity).
• Verify the fetal number (singleton vs. multiple gestation) as different codes apply for multiple gestations.
