P91.82Neonatal cerebral infarction

P91.82 is the ICD-10-CM diagnosis code for neonatal cerebral infarction. 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 4 subcodes must be used instead.

Within P91.8 (other specified disturbances of cerebral status of newborn), P91.82 is specifically for neonatal cerebral infarction. Related codes cover neonatal encephalopathy (P91.81) and other specified disturbances of cerebral status of newborn (P91.88).

To report this condition, pick the subcode that matches the documentation: P91.821 (right side of brain), P91.822 (left side of brain), P91.823 (bilateral) and P91.829 (unspecified side).

Don't report P91.82 together with the conditions in its Excludes1 note: cerebral infarction (I63.-).

The conditions in its Excludes2 note aren't part of P91.82, but may be coded alongside it if the patient has both: intracranial hemorrhage of newborn (P52.-).

It was added in FY2021, effective October 1, 2020.
