ICD-10-CM Code For Convulsions Of Newborn: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group P90 includes neonatal convulsions and related seizure disorders that begin in the perinatal period, covering seizures attributed to various causes such as hypoxia, infection, metabolic disturbances, or intracranial hemorrhage. These ICD-10-CM diagnosis codes are used to document acute neonatal seizure activity, capture underlying etiologies when known, and reflect the clinical complexity and organ system involvement of the central nervous system. Accurate coding within the ICD-10-CM P90 group supports proper claim adjudication and complete clinical documentation and appropriate reimbursement.

ICD-10-CM P90: Convulsions Of Newborn Overview

This group covers convulsive disorders that begin in the neonatal period, representing abnormal neuronal activity presenting as seizures in newborns. These conditions target the central nervous system in neonates and may reflect metabolic, infectious, hypoxic-ischemic, or structural causes. Accurate coding is important for clinical documentation and supports appropriate reimbursement for neonatal intensive care.

When to Use

Use a code from this group when a newborn exhibits clinical or electrographic seizure activity during the perinatal period. Assign additional codes to document known underlying causes, complications, or contributing conditions as documented in the medical record.

Typical Clinical Scenarios

Term neonate, age 12 hours, develops repetitive focal tonic-clonic movements of the right arm and leg with eyelid deviation and apnea shortly after birth; nursery staff initiate urgent evaluation for seizure activity, obtain EEG and neuroimaging, and start anticonvulsant therapy for acute neonatal seizures. A diagnosis from this group is assigned because the presenting events are convulsions occurring in the newborn period requiring inpatient management. Typical codes: P90
Late-preterm infant in the NICU with hypoxic-ischemic encephalopathy after a difficult delivery who shows intermittent myoclonic jerks and electrographic seizure activity on continuous EEG over several days; the convulsions are monitored as part of ongoing care and contribute to prognosis and treatment decisions. A code from this group is used to document convulsions attributable to the newborn period as a complication of perinatal insult. Typical codes: P90
Newborn discharged from the nursery returns to the emergency department on day 5 of life for multiple brief generalized tonic seizures at home after an otherwise unremarkable birth; clinicians evaluate for metabolic causes, infection, and intracranial pathology and admit the infant for workup and seizure control. Convulsions identified in this early neonatal presentation are coded using a code from this group to capture the acute neonatal seizure episode. Typical codes: P90
