About P84
P84 is the ICD-10-CM diagnosis code for other problems with newborn. It belongs to block P84 (other problems with newborn) 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.
Don't report P84 together with the conditions in its Excludes1 note: intracranial hemorrhage due to anoxia or hypoxia (P52.-), hypoxic ischemic encephalopathy [HIE] (P91.6-) and late metabolic acidosis of newborn (P74.0).
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 794 (Neonate with Other Significant Problems, relative weight 1.4935), 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 768.9 (unspecified severity of birth asphyxia in liveborn infant), 770.88 (hypoxemia of newborn) and 775.81 (other acidosis of newborn).
