P91.9
ICD-10-CMThis code represents a general, undefined alteration in a newborn's brain function or neurological state. It signifies that the infant is exhibiting signs of neurological distress or dysfunction, but the specific nature or cause of this disturbance has not yet been determined or documented.
Use this code when a newborn presents with non-specific neurological symptoms such as lethargy, irritability, poor feeding, or abnormal tone, and a more precise diagnosis of the cerebral disturbance is not available. It is appropriate when the medical record indicates a "disturbance of cerebral status" without further specificity.
