2025 ICD-10-CM code O99.334

Smoking (tobacco) complicating childbirth.

This code is used only on the maternal record and never on the newborn record. Use additional code from category Z3A to identify the specific week of pregnancy, if known.

The medical necessity for this code is established by the presence of smoking and its impact on the childbirth process. Documentation should clearly link the smoking to any complications experienced.

The physician attending to the childbirth is responsible for documenting the smoking status and any complications arising from it.

IMPORTANT:Use additional code from category F17 to identify type of tobacco nicotine dependence.

In simple words: This code indicates that the mother's smoking is affecting her childbirth.
