Attn and concentration deficit following ntrm subarach hemor

This code signifies a cognitive impairment characterized by difficulty sustaining attention and focusing, which has developed as a direct consequence of a non-traumatic subarachnoid hemorrhage. This neurological sequela impacts the patient's ability to process information and maintain mental effort.

Apply this code when documentation clearly links a patient's attention and concentration deficits to a prior subarachnoid hemorrhage that was not caused by trauma. This typically involves a history of spontaneous (e.g., aneurysmal) subarachnoid hemorrhage and subsequent neurocognitive evaluation confirming the specific deficit.

• Ensure the documentation explicitly states "nontraumatic" subarachnoid hemorrhage as the etiology.
• Distinguish from other post-stroke cognitive deficits; this code is specific to attention and concentration.
• Sequence this code after the primary code for the sequelae of the subarachnoid hemorrhage (e.g., I69.090 for other sequelae).
