ICD-10 Code I69.320 – Aphasia following cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.320 – Aphasia following cerebral infarction
What it is
I69.320 identifies aphasia that remains after a cerebral infarction, meaning a stroke has caused lasting language impairment. Use it when the record links the aphasia to the prior infarct.
Clinical signs
Clinical features vary; refer to documentation. Common findings include impaired speech production, difficulty understanding language, or trouble naming, reading, or writing after a stroke.
When to use this code
Use this code when the provider documents aphasia as a sequela of a cerebral infarction. It is appropriate for follow-up visits after the acute stroke phase when the language deficit is still present. Code the residual condition, not the acute infarct, unless both are being reported and documented.
Do not use for
Do not use it for aphasia unrelated to a stroke or when the cause is not documented. Check documentation if the language problem is acute, transient, or due to another neurologic condition.
Coding tip
Link the aphasia to the prior cerebral infarction in the record before assigning I69.320.
