In simple words: This code describes a difficult labor caused by a problem with the baby, such as a birth defect that makes delivery hard.The specific problem with the baby would also be listed separately.
This code is used to classify instances of obstructed labor where the primary cause is an abnormality of the fetus not specifically detailed in other codes within the O66 category.Examples include fetal ascites, hydrops fetalis, meningomyelocele, sacral teratoma, other tumors, or hydrocephalus.The underlying fetal anomaly should be additionally coded if known.
Example 1: A 38-year-old woman presents at 39 weeks gestation with prolonged labor and failure to progress.Ultrasound reveals a large fetal sacral teratoma causing obstruction of the birth canal. Code O66.3 is assigned.Code for the specific tumor is added as well., A 25-year-old woman at 40 weeks gestation is experiencing obstructed labor.The fetus has hydrocephalus, causing an excessively large head size.O66.3 is used along with a code specifying hydrocephalus., A 32-year-old woman is in labor and the fetus is found to have severe ascites that is causing obstructed labor.O66.3 is appropriate. The fetal ascites is also coded.
Detailed obstetrical history, including labor progress notes, fetal monitoring strips, ultrasound findings, physical examination of the mother and fetus, and any surgical intervention records.The specific fetal abnormality must be documented.
** This code is for use only on maternal records, not newborn records.Always code the underlying fetal anomaly if known.
