About P36

P36 is the ICD-10-CM diagnosis code for bacterial sepsis of newborn. 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: P36.0 (B), P36.1 (streptococci), P36.2 (aureus), P36.3 (staphylococci), P36.4 (coli), P36.5 (anaerobes), P36.8 (newborn) and P36.9 (unspecified).

Use an additional code(s), if applicable, to identify severe sepsis (R65.2-) and associated acute organ dysfunction(s).

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