Fntl lb and exec fcn def following ntrm subarach hemorrhage

This code signifies a persistent impairment in frontal lobe functions, such as planning, problem-solving, and decision-making, that developed as a direct consequence of a nontraumatic subarachnoid hemorrhage. It indicates a neurological sequela affecting higher-level cognitive processes after the acute hemorrhagic event has resolved.

Apply this code when documentation clearly links a patient's executive dysfunction to a previous nontraumatic subarachnoid hemorrhage. This is appropriate for patients presenting with long-term cognitive deficits impacting daily living, such as difficulty with organization, abstract thought, or impulse control, following such an event.

• Ensure the medical record explicitly states the subarachnoid hemorrhage was "nontraumatic" to differentiate from traumatic brain injury sequelae.
• Verify that the documentation specifies "frontal lobe" and "executive function" deficits, not just general cognitive impairment.
• Sequence this code after the acute subarachnoid hemorrhage code (if still active) or as a primary diagnosis if the patient is being treated specifically for these sequelae.
