About P00.2

P00.2 is the ICD-10-CM diagnosis code for newborn affected by maternal infectious and parasitic diseases. It belongs to category P00 (newborn affected by maternal conditions that may be unrelated to present pregnancy), block P00-P04 (newborn affected by maternal factors and by complications of pregnancy, labor, and delivery) 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 P00 (newborn affected by maternal conditions that may be unrelated to present pregnancy), P00.2 is specifically for newborn affected by maternal infectious and parasitic diseases. Related codes cover maternal hypertensive disorders (P00.0), maternal renal and urinary tract diseases (P00.1), other maternal circulatory and respiratory diseases (P00.3), maternal nutritional disorders (P00.4), maternal injury (P00.5), surgical procedure on mother (P00.6), other medical procedures on mother, not elsewhere classified (P00.7), other maternal conditions (P00.8) and 1 more.

Don't report P00.2 together with the conditions in its Excludes1 note: maternal genital tract or other localized infections (P00.8).

The conditions in its Excludes2 note aren't part of P00.2, but may be coded alongside it if the patient has both: infections specific to the perinatal period (P35-P39) and newborn affected by (positive) maternal group B streptococcus (GBS) colonization (P00.82).

Code first: any current condition in newborn.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 795 (Normal Newborn, relative weight 0.2022) and DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), 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 is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised).

Before ICD-10, this condition was coded in ICD-9-CM as 760.2 (maternal infections affecting fetus or newborn).
