Unsp symp and signs w cogn fnctns fol other cerebvasc dis

This code represents a sequela of a cerebrovascular event, other than a stroke, manifesting as unspecified cognitive deficits. These deficits could include issues with memory, attention, executive function, or language, where the specific nature of the cognitive impairment is not documented. It indicates a persistent neurological consequence following a prior cerebrovascular insult.

Use this code when a patient presents with cognitive symptoms that are clearly documented as residual effects of a cerebrovascular disease other than a stroke, and the specific type of cognitive dysfunction is not detailed. Documentation should explicitly link the cognitive impairment to a prior cerebrovascular event (e.g., transient ischemic attack, cerebral aneurysm rupture, or other non-stroke cerebrovascular conditions).

• Ensure the documentation specifies "other cerebrovascular disease" and not a stroke (I69.3- for stroke sequelae).
• Avoid using this code if more specific cognitive deficits (e.g., aphasia, apraxia, agnosia) are documented; instead, use the more specific I69.81x codes.
• This code should be sequenced after the code for the underlying cerebrovascular disease if the patient is still being treated for the acute phase, or as a primary diagnosis when the sequela is the focus of the encounter.
