Cerebral edema

This code represents an abnormal accumulation of fluid within the brain parenchyma, leading to increased intracranial pressure. This swelling can result from various underlying medical conditions, impairing brain function and potentially leading to serious neurological deficits.

Assign this code when documentation specifies cerebral edema not attributed to trauma or birth injury. This includes edema secondary to conditions like stroke, tumor, infection, metabolic encephalopathy, or severe hypertension. Supporting documentation should clearly state the presence of cerebral edema and rule out traumatic or birth-related etiologies.

• Always review the medical record to determine the underlying cause of the cerebral edema.
• Do not code this with S06.1- (traumatic cerebral edema) or P11.0 (cerebral edema due to birth injury).
• Sequence this code after the underlying condition causing the cerebral edema, if applicable.
