Aphasia following other cerebrovascular disease

This code signifies a language disorder characterized by impaired comprehension or expression of speech, reading, or writing, which has developed as a direct consequence of a cerebrovascular event other than a stroke (e.g., transient ischemic attack, cerebral aneurysm rupture, or cerebral venous thrombosis). The aphasia can manifest in various forms, such as global, Broca's, Wernicke's, or anomic aphasia.

Apply this code when documentation clearly links a patient's aphasia to a cerebrovascular disease other than a completed stroke. This is appropriate for patients presenting with new or persistent language deficits after experiencing conditions like a TIA, subarachnoid hemorrhage, or other non-stroke cerebrovascular incidents. The medical record should explicitly state the causal relationship.

• Always sequence this code after the code identifying the underlying cerebrovascular disease (e.g., I67.1, I67.89).
• Do not use this code if the aphasia is due to a completed stroke; instead, refer to codes in category I69.32.
• Ensure the documentation specifies "aphasia" and not just general "speech disturbance" to support this specific code.
