Dysarthria following cerebral infarction

This code describes difficulty with speech articulation (dysarthria) that occurs as a direct consequence of a cerebral infarction (ischemic stroke). It indicates a neurological deficit affecting the motor control of speech, resulting from damage to brain regions responsible for coordinating the muscles of the mouth, tongue, larynx, and respiratory system.

Use this code when documentation clearly links the patient's dysarthria to a previous cerebral infarction. This typically applies to patients presenting with persistent speech difficulties after an acute ischemic stroke event. Supporting documentation should include a diagnosis of dysarthria and a history of cerebral infarction, with the dysarthria noted as a sequela.

• Ensure the documentation specifies "following cerebral infarction" to differentiate from other causes of dysarthria.
• Do not use this code for dysarthria related to transient ischemic attacks (TIAs), as indicated by the Excludes2 note.
• Sequence this code after the code for the cerebral infarction (e.g., I69.3xx) if the infarction is still relevant to the current encounter.
