In simple words: This code indicates that the baby is lying sideways or at an angle in the uterus, requiring special care during pregnancy.

This code is used for maternal care due to a transverse or oblique fetal lie, where the fetus is lying horizontally or at an angle across the uterus, not in a head-down or breech position.This is applicable when this condition is the reason for observation, hospitalization, or other obstetric care of the mother, or for cesarean delivery before the onset of labor.

Example 1: A pregnant woman in her third trimester presents with a transverse lie confirmed by ultrasound.She is admitted for observation and possible ECV., A pregnant woman at term goes into labor with a transverse lie. The physician performs a cesarean delivery., A pregnant woman is found to have an oblique lie during a routine prenatal checkup. She receives counseling about possible delivery options and close monitoring.

Documentation should include the confirmation of the transverse/oblique lie (usually by ultrasound), the management plan (observation, ECV attempt, or planned cesarean), and any associated complications.

** This code excludes supervision of normal pregnancy (Z34.-), mental and behavioral disorders associated with the puerperium (F53.-), obstetrical tetanus (A34), postpartum necrosis of pituitary gland (E23.0), and puerperal osteomalacia (M83.0).It is important to distinguish between an oblique lie, which may convert to a longitudinal lie during labor, and a persistent transverse lie, which generally necessitates a cesarean delivery.
