Dysarthria following other cerebrovascular disease

This code signifies a speech disorder characterized by difficulty with articulation, phonation, or prosody, resulting from damage to the nervous system due to a cerebrovascular event other than an ischemic stroke or hemorrhagic stroke. It represents a residual neurological deficit impacting speech production following a non-specified cerebrovascular disease.

Use this code when documentation clearly indicates dysarthria as a sequela of a cerebrovascular accident not classified as ischemic or hemorrhagic (e.g., cerebral venous thrombosis, transient cerebral ischemia with residual deficits). The medical record should specify the type of cerebrovascular disease and confirm the presence of dysarthria as a lasting effect.

• Always sequence this code after the code for the underlying cerebrovascular disease (e.g., I67.6 for cerebral venous thrombosis).
• Do not use this code for dysarthria due to acute stroke; instead, code the acute stroke with associated dysarthria.
• Ensure documentation differentiates dysarthria from other speech disorders like aphasia or dysphonia.
