Nontraumatic intcrbl hemorrhage in hemisphere, cortical

This code signifies a spontaneous bleeding event occurring within the cerebral cortex of one hemisphere, not caused by external trauma. It represents an acute extravasation of blood directly into the brain tissue, specifically affecting the outer layer of the cerebrum.

Utilize this code when documentation clearly states an intracerebral hemorrhage is nontraumatic and localized to the cortical region of a cerebral hemisphere. Supporting documentation should include imaging reports (e.g., CT, MRI) confirming the hemorrhage location and ruling out traumatic etiology.

• Differentiate from subcortical hemorrhages; this code is specific to the cortical layer.
• Ensure the documentation explicitly states "nontraumatic" to avoid miscoding with traumatic intracranial hemorrhages.
• Always sequence this code as the primary diagnosis if it is the reason for the encounter, followed by any associated conditions like hypertension.
