P91.8Other specified disturbances of cerebral status of newborn

P91.8 is the ICD-10-CM diagnosis code for other specified disturbances of cerebral status of newborn. It belongs to category P91 (other disturbances of cerebral status of newborn), block P90-P96 (other disorders originating in the perinatal period) and chapter 16 (certain conditions originating in the perinatal period). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within P91, choose P91.8 (Other specified disturbances of cerebral status of newborn) only when documentation doesn't support a more specific option: neonatal cerebral ischemia (P91.0), acquired periventricular cysts of newborn (P91.1), neonatal cerebral leukomalacia (P91.2), neonatal cerebral irritability (P91.3), neonatal cerebral depression (P91.4), neonatal coma (P91.5), hypoxic ischemic encephalopathy [HIE] (P91.6) and disturbance of cerebral status of newborn, unspecified (P91.9).

To report this condition, pick the subcode that matches the documentation: P91.81 (encephalopathy), P91.82 (infarction) and P91.88 (newborn).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2018 (expanded into subcodes).
