Maternal care for damage to fetus by drugs, fetus 2

This code signifies maternal care provided when there is a suspected or confirmed adverse effect on the fetus due to maternal drug exposure. This includes situations where the mother's use of prescribed, over-the-counter, or illicit drugs is believed to have caused damage or developmental issues in the fetus. The "2" in the seventh character indicates that this is a second fetus in a multiple gestation pregnancy.

Use this code when documentation clearly indicates maternal care for a fetus (specifically the second fetus in a multiple gestation) with suspected or confirmed damage attributed to maternal drug use. This applies to scenarios such as fetal growth restriction, congenital anomalies, or withdrawal symptoms linked to maternal substance exposure. Supporting documentation should specify the drug(s) involved and the suspected fetal impact.

• Always sequence this code after the primary obstetric code (e.g., O30.0XX2 for twin pregnancy).
• Ensure documentation specifies "fetus 2" to justify the seventh character.
• Do not use this code for maternal drug dependence or abuse without documented fetal impact; use codes from Chapter 5 (Mental, Behavioral and Neurodevelopmental disorders) for the mother's condition.
