Preterm newborn, gestational age 34 completed weeks

This code identifies a liveborn infant delivered prematurely at exactly 34 completed weeks of gestation. It signifies a late preterm birth, a critical period for neonatal development and adaptation outside the womb.

Apply this code for newborns documented as being born at 34 weeks and 0 days through 34 weeks and 6 days of gestation. This is typically used as a secondary diagnosis to further specify the prematurity of the infant, often alongside codes for other conditions related to preterm birth.

• Always confirm the exact gestational age at birth from the medical record, typically documented by the neonatologist or obstetrician.
• Do not confuse "completed weeks" with "weeks and days"; 34 completed weeks means the infant is not yet 35 completed weeks.
• This code should be sequenced after the primary diagnosis for the newborn's condition, unless it is the reason for the encounter.
