    ICD-10-CM Code For Other Disturbances Of Cerebral Status Of Newborn: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group P91 includes neonatal disturbances of cerebral status such as seizures, tremors, and other altered levels of consciousness arising in the perinatal period. These ICD-10-CM diagnosis codes are used to document acute neurologic dysfunction in newborns, capturing severity, timing, and associated neonatal complications relevant to cerebral injury or dysfunction. Accurate coding within the ICD-10-CM P91 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM P91: Other Disturbances Of Cerebral Status Of Newborn Overview

    The ICD-10-CM P91 group represents disturbances of cerebral status occurring in the newborn period, including conditions such as neonatal seizures, tremors, and other altered levels of consciousness. These diagnoses target the central nervous system in neonates and reflect acute neurologic dysfunction related to perinatal events, metabolic disturbances, infection, or structural injury. Accurate coding ensures the clinical picture and care complexity are fully documented, which supports appropriate billing and continuity of care.

    When to Use

    Use a code from this group when a newborn presents with documented cerebral dysfunction such as seizures, tremors, or stupor that are attributable to perinatal events or neonatal conditions. Assign specific codes that reflect the clinical findings, timing, and any identified underlying causes to accurately convey severity and resource needs.

    Typical Clinical Scenarios

    • A term newborn develops seizures within the first 24 hours of life after a difficult delivery with fetal distress and low Apgar scores; the infant is admitted to the NICU, undergoes EEG monitoring and neuroimaging to evaluate for hypoxic-ischemic injury, and a perinatal-onset encephalopathy or seizure disorder is diagnosed because the cerebral dysfunction is present in the immediate newborn period. Typical codes: P91.0, P91.2
    • A preterm infant in the second week of life exhibits episodic apnea and bradycardia associated with impaired feeding and fluctuating consciousness; the neonatology team documents an ongoing disturbance of neurologic status attributed to prematurity-related immaturity or metabolic instability requiring prolonged monitoring and supportive care, prompting assignment of a code for persistent or recurrent cerebral disturbance of the newborn. Typical codes: P91.61, P91.62
    • A newborn who required therapeutic hypothermia for suspected perinatal asphyxia develops later feeding difficulties, abnormal tone, and intermittent abnormal movements while recovering on the postnatal ward; these findings are recorded as neurologic sequelae or complications of the perinatal period and coded to reflect residual or specified disturbances of cerebral status. Typical codes: P91.3, P91.82
