Neonatal coma

This code signifies a state of profound unconsciousness in a newborn, characterized by unresponsiveness to external stimuli and absent or minimal brainstem reflexes. It indicates a severe neurological impairment in the neonatal period, often stemming from perinatal injury or congenital anomalies.

Assign this code when documentation explicitly states a diagnosis of neonatal coma. This typically applies to newborns presenting with a Glasgow Coma Scale (GCS) score of 8 or less, or other clinical indicators of deep unconsciousness. Supporting documentation should include neurological assessments, physician notes, and potentially imaging reports.

• Always ensure the documentation specifies "neonatal" coma to differentiate from coma in older patients.
• Do not use this code for lethargy, stupor, or other less severe states of altered consciousness.
• Code any underlying cause of the neonatal coma (e.g., birth asphyxia, intracranial hemorrhage) as a primary diagnosis if known and documented.
