Nontraumatic subarachnoid hemorrhage from r verteb art

This code signifies bleeding into the subarachnoid space, specifically originating from a non-traumatic rupture of the right vertebral artery. This condition is a type of hemorrhagic stroke, often presenting with sudden, severe headache and neurological deficits.

Use this code when documentation clearly identifies a subarachnoid hemorrhage due to a spontaneous (nontraumatic) rupture of the right vertebral artery. Supporting documentation should include imaging reports (e.g., CT angiography, MRI) confirming the hemorrhage and its specific arterial source.

• Ensure the documentation specifies "nontraumatic" to differentiate from traumatic subarachnoid hemorrhage.
• Verify the laterality and specific vessel (right vertebral artery) are explicitly stated in the physician's notes or diagnostic reports.
• Do not use this code if the hemorrhage is due to an aneurysm of the right vertebral artery; a more specific code for ruptured aneurysm would be appropriate.
