What This Code Means

Bleeding inside the brain that occurs in the fluid-filled chambers (ventricles) of the brain, not caused by trauma or injury.

Coding Tips

• •Verify the hemorrhage is nontraumatic and specifically located in the intraventricular space
• •Review imaging reports to confirm ventricle involvement and rule out traumatic causes

Clinical Significance

Nontraumatic intraventricular hemorrhage involves bleeding within the brain's ventricular system and can lead to obstructive hydrocephalus, elevated intracranial pressure, and significant neurological deterioration. This condition may occur as a primary event or as extension from other intracerebral hemorrhage sites. It is a critical diagnosis for risk adjustment reflecting the need for intensive neurological monitoring and potential ventricular drainage procedures.

Documentation Requirements

• ✓Imaging confirmation (CT or MRI) showing hemorrhage within the ventricular system
• ✓Documentation of nontraumatic cause
• ✓Assessment for hydrocephalus or ventricular enlargement
• ✓Documentation of whether this is primary intraventricular hemorrhage or extension from parenchymal bleeding
• ✓Clinical presentation including headache, altered consciousness, and neurological findings
• ✓Treatment plan including potential external ventricular drain placement
