Newborn affected by maternal use of unsp drugs of addiction

This code signifies a newborn exhibiting signs or symptoms of withdrawal or other adverse effects due to the mother's prenatal exposure to an unspecified addictive substance. It indicates a direct impact on the neonate from maternal substance use where the specific drug is not documented.

Assign this code when a neonate presents with drug withdrawal symptoms, neurological abnormalities, or other complications directly attributable to maternal substance abuse, and the specific drug of addiction is not identified in the medical record. Documentation should clearly link the newborn's condition to maternal drug use without specifying the substance.

• Do not use if the specific drug of addiction is known; instead, use the more specific P04.4x codes.
• Always sequence this code as a secondary diagnosis, following the code for the newborn's specific manifestation (e.g., neonatal withdrawal syndrome).
• Requires physician documentation explicitly stating maternal drug use affecting the newborn, without identifying the drug.
