About P36.0
P36.0 is the ICD-10-CM diagnosis code for sepsis of newborn due to streptococcus, group B. It belongs to category P36 (bacterial sepsis of newborn), block P35-P39 (infections specific to the perinatal period) and chapter 16 (certain conditions originating in the perinatal period). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within P36 (bacterial sepsis of newborn), P36.0 is specifically for sepsis of newborn due to streptococcus, group B. Related codes cover sepsis of newborn due to other and unspecified streptococci (P36.1), sepsis of newborn due to Staphylococcus aureus (P36.2), sepsis of newborn due to other and unspecified staphylococci (P36.3), sepsis of newborn due to Escherichia coli (P36.4), sepsis of newborn due to anaerobes (P36.5), other bacterial sepsis of newborn (P36.8) and unspecified (P36.9).
Use an additional code(s), if applicable, to identify severe sepsis (R65.2-) and associated acute organ dysfunction(s).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 771.81 (septicemia [sepsis] of newborn).
