Nontraumatic intracerebral hemorrhage, intraventricular

This code represents a spontaneous bleeding event occurring within the brain tissue (intracerebral) that has extended into the ventricular system. This type of hemorrhage is not caused by external trauma and often results from underlying vascular abnormalities or systemic conditions.

Apply this code when documentation clearly indicates a non-traumatic intracerebral hemorrhage with involvement of the intraventricular spaces. This is typically diagnosed via imaging studies such as CT or MRI of the brain, showing both parenchymal and intraventricular blood.

• Ensure documentation specifies "nontraumatic" to differentiate from traumatic intracranial hemorrhages.
• Confirm the hemorrhage extends into the ventricles; if not, a more specific intracerebral hemorrhage code without intraventricular involvement may be appropriate.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, followed by codes for any underlying causes (e.g., hypertension, cerebral amyloid angiopathy).
