P90
ICD-10-CMThis code signifies the occurrence of seizure-like activity in a neonate, typically within the first 28 days of life, that is not otherwise specified as a more definitive seizure disorder. These convulsions are involuntary muscle contractions or spasms that can manifest in various forms, indicating an underlying neurological disturbance.
Assign this code when documentation clearly indicates a newborn experienced convulsions, and a more specific diagnosis for the seizure etiology (e.g., hypoxic-ischemic encephalopathy, metabolic disorder, infection) is not yet established or is ruled out. This code is appropriate for initial presentations of neonatal seizures where the precise cause remains undetermined.
