Nontraumatic subarachnoid hemorrhage from oth intracran art

This code signifies a spontaneous (nontraumatic) bleeding event into the subarachnoid space of the brain, originating from an intracranial artery other than the common sites like the anterior communicating or middle cerebral arteries. This type of hemorrhage is often caused by the rupture of an aneurysm.

Assign this code when documentation specifies a nontraumatic subarachnoid hemorrhage and identifies the source as an intracranial artery not otherwise specified or explicitly states an "other" intracranial artery. This code is appropriate when the specific arterial source is known but falls outside the more common named arteries with dedicated codes.

• Ensure documentation clearly states the hemorrhage is nontraumatic.
• Verify the specific intracranial artery involved; if a more specific code exists for that artery (e.g., anterior communicating), use that instead.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
