The diagnosis of smoking complicating pregnancy is medically necessary due to its significant impact on maternal and fetal health. This includes increased risk of preterm birth, low birth weight, placental abruption, and sudden infant death syndrome.
Obstetricians and other healthcare professionals involved in prenatal and postnatal care are responsible for documenting and coding tobacco use in pregnant patients.

- O99.33- Smoking (tobacco) complicating pregnancy, childbirth, and the puerperium
In simple words: This code is for pregnant women who smoke and it affects their pregnancy. The doctor will also use a code to show exactly what kind of tobacco product the woman used (like cigarettes or chewing tobacco) and if they have any problems because of it.
This code classifies smoking or tobacco use that complicates a pregnancy, without specifying the trimester.It is crucial to use an additional code from category F17 (Nicotine dependence) to specify the type of tobacco product used and any related nicotine-induced disorders (e.g., withdrawal, remission).
Example 1: A 28-year-old woman at 20 weeks gestation presents for a routine prenatal checkup.She admits to smoking approximately half a pack of cigarettes daily.Codes O99.332 and F17.210 (Nicotine dependence, cigarettes, uncomplicated) are assigned., A 35-year-old woman, postpartum day 5, reports difficulty sleeping and increased irritability. She reveals a history of smoking during pregnancy.Codes O99.335 (Smoking (tobacco) complicating the puerperium) and F17.213 (Nicotine dependence, cigarettes, with withdrawal) are assigned., A 25-year-old woman at 36 weeks gestation is hospitalized for pre-eclampsia. She reports smoking a pipe tobacco. Codes O99.333 and F17.290 (Nicotine dependence, other tobacco product, uncomplicated) should be used.
Complete and accurate documentation is essential.This includes: patient's reported tobacco use (type and quantity), trimester of pregnancy if applicable, and any associated nicotine-induced disorders (withdrawal, remission).
** This code should only be used for maternal records.It should not be used on newborn records.The use of additional codes from category F17 is mandatory for proper coding and reimbursement.
