Preterm newborn, gestational age 29 completed weeks

This code identifies a newborn delivered prematurely, specifically at a gestational age of 29 completed weeks. This signifies a significantly preterm birth, indicating potential immaturity of organ systems and increased risk for various neonatal complications.

Assign this code for liveborn infants documented as being born at 29 completed weeks of gestation. Documentation must clearly state the gestational age at birth, typically derived from obstetric ultrasound or last menstrual period (LMP) calculations.

• Always sequence this code as a secondary diagnosis following the appropriate Z38 code for liveborn infant.
• Ensure the documented gestational age precisely matches "29 completed weeks"; do not round up or down.
• Do not use this code if the gestational age is documented as "29 weeks and X days"; instead, select the appropriate code for the completed week.
