P24.3Neonatal aspiration of milk and regurgitated food

P24.3 is the ICD-10-CM diagnosis code for neonatal aspiration of milk and regurgitated food. It belongs to category P24 (neonatal aspiration), block P19-P29 (respiratory and cardiovascular disorders specific to the perinatal period) and chapter 16 (certain conditions originating in the perinatal period). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within P24 (neonatal aspiration), P24.3 is specifically for neonatal aspiration of milk and regurgitated food. Related codes cover meconium aspiration (P24.0), of (clear) amniotic fluid and mucus (P24.1), of blood (P24.2), other neonatal aspiration (P24.8) and unspecified (P24.9).

To report this condition, pick the subcode that matches the documentation: P24.30 (without respiratory symptoms) and P24.31 (with respiratory symptoms).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
