P93.0Grey baby syndrome

P93.0 is the ICD-10-CM diagnosis code for Grey baby syndrome. It belongs to category P93 (reactions and intoxications due to drugs administered to newborn), block P90-P96 (other disorders originating in 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 P93 (reactions and intoxications due to drugs administered to newborn), P93.0 is specifically for Grey baby syndrome. Related codes cover other reactions and intoxications due to drugs administered to newborn (P93.8).

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 779.4 (drug reactions and intoxications specific to newborn).
