About P37

P37 is the ICD-10-CM diagnosis code for other congenital infectious and parasitic diseases. It belongs to block P35-P39 (infections 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P37.0 (tuberculosis), P37.1 (toxoplasmosis), P37.2 (listeriosis), P37.3 (malaria), P37.4 (malaria), P37.5 (candidiasis), P37.8 (diseases) and P37.9 (unspecified).

The conditions in its Excludes2 note aren't part of P37, but may be coded alongside it if the patient has both: congenital syphilis (A50.-), infectious neonatal diarrhea (A00-A09), necrotizing enterocolitis in newborn (P77.-), noninfectious neonatal diarrhea (P78.3) and 2 more.

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