Fluency disorder following cerebral infarction

This code signifies a speech fluency disorder, such as stuttering or cluttering, that develops as a direct consequence of a cerebral infarction (ischemic stroke). It indicates a neurological impairment affecting the rhythm and flow of speech, specifically linked to a past stroke event.

Apply this code when documentation clearly states a patient is experiencing a fluency disorder and explicitly links its etiology to a prior cerebral infarction. This diagnosis is appropriate for patients presenting with new-onset or exacerbated dysfluency following a stroke, after other causes have been ruled out.

• Always sequence this code after the appropriate code for the cerebral infarction (e.g., I63.x).
• Ensure documentation specifies "fluency disorder" and not just general "speech disturbance" to support this specific code.
• Distinguish from other speech disorders post-stroke, such as aphasia (R47.0x) or dysarthria (R47.1), which have separate codes.
