ICD-10 Code I69.323 – Fluency disorder following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.323 – Fluency disorder following cerebral infarction
What it is
This code identifies a fluency problem, such as difficulty producing smooth, connected speech, that occurs after a cerebral infarction. It is used when the speech disturbance is a late effect of the stroke.
Clinical signs
Patients may have interrupted speech, abnormal speech rate, or difficulty initiating words after a documented cerebral infarction. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents fluency disorder as a residual effect of a prior cerebral infarction. It applies to ongoing speech impairment linked to the stroke, not to the acute infarct itself. Confirm the record shows a causal relationship and that the condition is current.
Do not use for
Do not use this code for acute stroke care or for speech problems without documented connection to cerebral infarction. Check documentation if the record only says aphasia, dysarthria, or unspecified communication difficulty.
Coding tip
Code the residual speech disorder only when the stroke sequela is clearly documented and the infarction is no longer acute.
