Preterm newborn, gestational age 28 completed weeks

This code identifies a liveborn infant delivered prematurely at exactly 28 completed weeks of gestation. It signifies a very preterm birth, indicating a higher risk for various neonatal complications due to immature organ systems.

Use this code for newborns documented as having a gestational age of 28 completed weeks at birth. Documentation should clearly state the gestational age as determined by obstetric ultrasound, last menstrual period, or postnatal assessment.

• Ensure the documentation specifies "completed weeks" to avoid ambiguity.
• Do not use this code if the gestational age is 28 weeks and 1 day or more; a different code for 29 weeks would be appropriate.
• Always sequence this code as a secondary diagnosis following the appropriate Z38.- code for liveborn infant.
