(Active) Effective Date: N/A Revision Date: N/A Pregnancy, childbirth and the puerperium - Other obstetric conditions, not elsewhere classified (O94-O9A) Chapter 19: Pregnancy, childbirth and the puerperium (O00-O9A) Feed
Smoking (tobacco) complicating pregnancy, third trimester.
No specific modifiers are typically required for this code, but modifiers may be needed depending on the circumstances of the encounter.
Medical necessity is established when smoking during pregnancy directly impacts the maternal or fetal health, leading to adverse outcomes. This may include but is not limited to pre-eclampsia, preterm labor, low birth weight, respiratory problems, or other complications.
Obstetricians and other healthcare providers involved in prenatal and postnatal care are responsible for managing the pregnancy and addressing the complications related to smoking.

- O99.333 falls under the broader category of O99.33 - Smoking (tobacco) complicating pregnancy.This further classifies the complication to the third trimester.
In simple words: This code is for pregnant women in their third trimester (28 weeks or later) whose smoking is causing problems for them or their baby.
This code classifies smoking or tobacco use as a complication arising during the third trimester of pregnancy.It is used when tobacco use negatively impacts the mother's health or the pregnancy's progression.The third trimester is defined as gestational week 28 and beyond.
Example 1: A 35-year-old pregnant woman at 32 weeks gestation presents with persistent cough and shortness of breath, exacerbated by smoking. The physician documents a diagnosis of O99.333, considering the impact of smoking on the respiratory system and fetal well-being., A 28-year-old patient at 36 weeks gestation is admitted for pre-eclampsia.She is a smoker.O99.333 is coded in addition to the pre-eclampsia code to reflect the additional risk factor., A 40-year-old woman at 30 weeks gestation reports increased anxiety and difficulty sleeping, related to nicotine withdrawal.She is attempting to quit smoking.O99.333 is coded to reflect the smoking-related complications and the associated maternal psychological impact.
* Detailed history of tobacco use (frequency, duration, type).* Documentation of respiratory symptoms (cough, shortness of breath), cardiovascular symptoms (chest pain, palpitations), and other health issues potentially related to smoking.* Fetal monitoring data (ultrasound, fetal heart rate monitoring).* Assessment of maternal health indicators (blood pressure, weight, urine analysis).* Gestational age documentation, confirming that it is indeed the third trimester.* Physician's note linking smoking to maternal or fetal complications.
** This code is for use in maternal records only.It should not be used on newborn records.The diagnosis should be supported by clinical documentation demonstrating the link between smoking and adverse maternal or fetal outcomes.Use of this code does not imply causality.
