In simple words: This code describes a stroke in a baby shortly before or after birth. A stroke happens when blood flow to part of the brain is blocked, causing brain damage.

This code classifies neonatal cerebral infarction, a stroke affecting newborns.It refers to the blockage of blood supply to a part of the brain in a newborn, leading to tissue death. This condition can manifest in various ways depending on the location and extent of the infarction.The code excludes cerebral infarction in individuals older than 28 days (coded elsewhere) and intracranial hemorrhage in newborns (P52.-).

Example 1: A newborn presents with neurological symptoms such as weakness on one side of the body, seizures, and difficulty feeding.Imaging studies (MRI or CT scan) reveal an infarcted area in the brain consistent with neonatal cerebral infarction. , A full-term infant born via vaginal delivery develops hypotonia and feeding difficulties within the first few days of life.A subsequent MRI confirms a periventricular ischemic lesion suggestive of perinatal arterial ischemic stroke (PAIS)., A premature infant experiences a period of severe hypoxia during delivery.Postnatal neurological examination reveals signs of cerebral palsy, and subsequent imaging shows a large area of cerebral infarction in the brain, consistent with hypoxic-ischemic encephalopathy and an infarction.

Complete obstetric history, including prenatal care, labor and delivery details (e.g., apgar scores, resuscitation efforts, presence of hypoxia or hypotension), and postnatal course.Neurological exam findings including muscle tone, reflexes, cranial nerves.Neuroimaging studies (MRI or CT scan) demonstrating the presence, location, and extent of the infarction.

** This code is utilized for various types of neonatal cerebral infarction. The specific location and extent of infarction may be further specified using additional codes or modifiers if detailed information is available.
