Fluency disorder following other cerebrovascular disease

This code signifies a speech fluency disorder, such as stuttering or cluttering, that develops as a direct consequence of a cerebrovascular event other than a stroke (e.g., transient ischemic attack, cerebral hemorrhage not specified as stroke, or other non-stroke related cerebral infarction). It indicates an acquired communication deficit affecting the rate, rhythm, and flow of speech.

Apply this code when documentation clearly links a patient's new or exacerbated fluency disorder to a prior cerebrovascular disease not classified as a stroke. This typically involves a neurologist's or speech-language pathologist's assessment confirming the causal relationship and ruling out other etiologies. Supporting documentation should detail the type of cerebrovascular event and the characteristics of the fluency impairment.

• Always sequence the underlying cerebrovascular disease code first, followed by this code.
• Distinguish from fluency disorders of developmental origin (F80.81) or those due to stroke (I69.323, I69.123, etc.).
• Ensure the medical record specifies "other cerebrovascular disease" as the etiology, not just "stroke."
