About P35

P35 is the ICD-10-CM diagnosis code for congenital viral 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P35.0 (syndrome), P35.1 (infection), P35.2 (infection), P35.3 (hepatitis), P35.4 (disease), P35.8 (diseases) and P35.9 (unspecified).

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