Maternal care for damage to fetus by drugs, fetus 4

This code signifies maternal care provided due to suspected or confirmed fetal damage resulting from the mother's drug use during pregnancy, specifically for a fetus identified as the fourth in a multiple gestation. It indicates that the maternal care is directly related to monitoring and managing potential adverse effects on the fetus caused by drug exposure.

Apply this code when documentation clearly states maternal care is being rendered because of drug-induced fetal damage or suspected damage, and the patient is carrying quadruplets, with the fourth fetus being the affected one. This includes scenarios where illicit drugs, prescription medications, or over-the-counter drugs are implicated in the fetal harm. Supporting documentation should specify the drug exposure and the concern for fetal impact.

• Always sequence this code as a secondary diagnosis, following the primary maternal condition or reason for encounter.
• Ensure the medical record explicitly identifies the fetus as the "fourth" in a multiple gestation to justify the "4" in the seventh character.
• Do not use this code for fetal abnormalities not linked to maternal drug use; instead, use codes from categories O35.0-O35.4 or O35.7-O35.9.
