P39.2Intra-amniotic infection affecting newborn, not elsewhere classified

P39.2 is the ICD-10-CM diagnosis code for Intra-amniotic infection affecting newborn, not elsewhere classified. It belongs to category P39 (other infections specific to the perinatal period), 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 P39 (other infections specific to the perinatal period), P39.2 is specifically for Intra-amniotic infection affecting newborn, not elsewhere classified. Related codes cover neonatal infective mastitis (P39.0), neonatal conjunctivitis and dacryocystitis (P39.1), neonatal urinary tract infection (P39.3), neonatal skin infection (P39.4), other specified infections specific to the perinatal period (P39.8) and infection specific to the perinatal period, unspecified (P39.9).

Use an additional code to identify organism or specific infection.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" 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 771.89 (other infections specific to the perinatal period).
