Nontraumatic intracerebral hemorrhage in hemisphere, unsp

This code signifies a spontaneous bleeding event within the brain tissue of an unspecified cerebral hemisphere, not caused by external trauma. It represents an acute cerebrovascular accident where blood extravasates directly into the brain parenchyma.

Apply this code when documentation clearly indicates an intracerebral hemorrhage without a traumatic etiology, and the specific hemisphere (left or right) is not documented. This is typically supported by imaging reports (CT or MRI) confirming intraparenchymal bleeding and physician notes ruling out trauma.

• Ensure documentation explicitly states "nontraumatic" or provides sufficient detail to rule out trauma.
• If the specific hemisphere (left or right) is documented, use the more precise codes I61.0 or I61.1.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless a definitive underlying cause (e.g., hypertension, amyloid angiopathy) is also being treated and is documented as the principal diagnosis.
