Aphasia following unspecified cerebrovascular disease

This code signifies aphasia, a disorder affecting language comprehension or production, that occurs as a sequela of a cerebrovascular event. The specific type of cerebrovascular disease (e.g., stroke, hemorrhage) is not documented or is unknown.

Use this code when a patient presents with aphasia clearly attributed to a past cerebrovascular incident, but the precise nature of that incident is not specified in the medical record. Documentation should explicitly link the aphasia to a "CVA," "stroke," or other cerebrovascular event without further detail.

• Always attempt to obtain documentation specifying the type of cerebrovascular disease (e.g., ischemic, hemorrhagic) for more specific coding.
• This code is for sequelae, meaning the cerebrovascular event itself has concluded, and the aphasia is a residual effect.
• Do not use this code for acute aphasia occurring during the initial cerebrovascular event; instead, code the acute stroke with aphasia as a manifestation.
