About P78

P78 is the ICD-10-CM diagnosis code for other perinatal digestive system disorders. It belongs to block P76-P78 (digestive system disorders of newborn) 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P78.0 (perforation), P78.1 (peritonitis), P78.2 (blood), P78.3 (diarrhea), P78.8 (disorders) and P78.9 (unspecified).

Don't report P78 together with the conditions in its Excludes1 note: cystic fibrosis (E84.0-E84.9) and neonatal gastrointestinal hemorrhages (P54.0-P54.3).

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