Attn and concentration deficit fol other cerebvasc disease

This code signifies a cognitive impairment characterized by difficulties in sustaining attention and focusing, occurring as a sequela of a cerebrovascular event other than a stroke (e.g., transient ischemic attack, cerebral aneurysm rupture, or other non-stroke cerebrovascular disease). It describes a chronic or persistent deficit in cognitive function directly attributable to a past cerebrovascular incident.

Apply this code when documentation clearly indicates a patient is experiencing ongoing attention and concentration deficits that are a direct consequence of a previously diagnosed cerebrovascular disease, excluding stroke. This code is appropriate for conditions like post-TIA cognitive impairment or cognitive sequelae following a cerebral hemorrhage not coded as a stroke. Physician notes must explicitly link the cognitive deficit to the "other cerebrovascular disease."

• Ensure the underlying cerebrovascular disease is clearly documented and is not classified as a stroke (I60-I63).
• This code requires a documented causal link between the cerebrovascular event and the attention/concentration deficit.
• Sequence this code after the code for the underlying cerebrovascular disease if it is still active, or as a primary diagnosis if the sequela is the focus of the encounter.
