Periventricular leukomalacia

This code identifies brain injury in neonates characterized by necrosis of white matter near the cerebral ventricles. It results from ischemia or hypoxia, leading to cystic lesions and potential long-term neurological deficits.

Use this code for infants diagnosed with periventricular leukomalacia, typically identified via cranial ultrasound or MRI. Documentation should clearly state the diagnosis, often in the context of prematurity or perinatal complications.

• Ensure documentation specifies "periventricular leukomalacia" and not just general white matter injury.
• Consider sequencing this code after codes for prematurity or other perinatal conditions that may have contributed to its development.
• Do not confuse with other types of neonatal cerebral injury without specific mention of periventricular white matter necrosis.
