Ntrm subarach hemorrhage from right middle cerebral artery

This code signifies a spontaneous (non-traumatic) bleeding into the subarachnoid space, specifically originating from the right middle cerebral artery. This is a serious type of stroke caused by a ruptured aneurysm or other vascular malformation in this particular cerebral vessel.

Apply this code when documentation clearly indicates a subarachnoid hemorrhage that is explicitly stated as nontraumatic and originating from the right middle cerebral artery. This typically follows diagnostic imaging (e.g., CT angiography, MRI) confirming the source of the hemorrhage.

• Ensure documentation specifies "nontraumatic" to differentiate from traumatic subarachnoid hemorrhage (S06.6-).
• Verify the laterality and specific vessel (right middle cerebral artery) are clearly documented.
• Sequence this code as the primary diagnosis when it is the reason for the encounter.
