P78.9
ICD-10-CMThis code signifies a digestive system disorder originating during the perinatal period (from the 28th week of gestation through 28 days after birth) where the specific nature of the condition is not documented. It encompasses a broad range of gastrointestinal issues in a neonate or fetus that lack a more precise diagnosis.
Utilize this code when documentation indicates a perinatal digestive system problem, but the physician has not specified a more definitive diagnosis (e.g., necrotizing enterocolitis, intestinal obstruction, or meconium ileus). This is often a temporary code used when initial diagnostic workup is incomplete or inconclusive.
