In simple words: This code is for pregnant women who smoke and experience complications during the first three months of pregnancy. The doctor needs to know what type of tobacco product was used.This code is only for the mother's medical record, not for the baby's.
This code classifies smoking (tobacco) use that complicates a pregnancy during the first trimester (less than 14 weeks 0 days gestation).It should be used in conjunction with an additional code from category F17 (Nicotine dependence) to specify the type of tobacco product used and the presence of any nicotine-induced disorders.The code is exclusively for maternal records; it should never be used for newborn records.Conditions included are those that complicate the pregnancy, are aggravated by it, or are a primary reason for obstetric care.This code excludes situations where the reason for maternal care is due to a condition affecting the fetus.
Example 1: A 28-year-old woman at 8 weeks gestation presents to her OB/GYN for a routine prenatal visit. During the visit, she discloses smoking approximately one pack of cigarettes daily. The physician documents the tobacco use and its potential risks to the pregnancy. O99.331 is coded with an additional code from F17 specifying the tobacco product., A 35-year-old woman at 12 weeks gestation is admitted to the hospital due to pregnancy-induced hypertension, potentially exacerbated by her smoking habit (one pack per day).O99.331 is coded along with codes for hypertension and any other relevant complications., A 25-year-old patient at 10 weeks gestation is seen for prenatal care. She reports smoking and using chewing tobacco.O99.331 is used along with codes from F17 to specify the tobacco products and any associated diagnoses (e.g., nicotine dependence).
