About P96.9

P96.9 is the ICD-10-CM diagnosis code for condition originating in the perinatal period, unspecified. It belongs to category P96 (other conditions originating in the perinatal period), 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 P96, choose P96.9 (Condition originating in the perinatal period, unspecified) only when documentation doesn't support a more specific option: congenital renal failure (P96.0), neonatal withdrawal symptoms from maternal use of drugs of addiction (P96.1), withdrawal symptoms from therapeutic use of drugs in newborn (P96.2), Wide cranial sutures of newborn (P96.3), complication to newborn due to (fetal) intrauterine procedure (P96.5) and other specified conditions originating in the perinatal period (P96.8).

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 779.9 (unspecified condition originating in the perinatal period).
