Extreme immaturity of NB, gestatnl age 26 completed weeks

This code identifies a newborn delivered at 26 completed weeks of gestation, indicating a state of extreme prematurity. This gestational age is associated with significant physiological immaturity and a high risk of complications requiring intensive neonatal care.

Assign this code for liveborn infants documented as having a gestational age of exactly 26 completed weeks at birth. Documentation must clearly state the gestational age in weeks, typically derived from early ultrasound or last menstrual period (LMP) if reliable.

• Always confirm the exact gestational age in completed weeks from the medical record.
• Do not use this code if the gestational age is 25 weeks 6 days or less, or 26 weeks 1 day or more; specific codes exist for other gestational age ranges.
• This code is a secondary diagnosis, following the Z38.- code for liveborn infant according to place of birth.
