ICD-10 Code I69.920 – Aphasia following unspecified cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.920 – Aphasia following unspecified cerebrovascular disease
What it is
I69.920 identifies aphasia that remains after an unspecified cerebrovascular disease. Use it when the chart links the language impairment to a prior stroke or other cerebrovascular event, but the exact type is not documented.
Clinical signs
Clinical features vary; refer to documentation. Aphasia may present as trouble speaking, understanding speech, reading, or writing, with the language deficit attributed to a cerebrovascular cause.
When to use this code
Use this code when the provider documents aphasia as a late effect or residual condition of unspecified cerebrovascular disease. It fits follow-up visits where the acute event is no longer the focus and the language deficit persists. Confirm that the record clearly connects aphasia to the cerebrovascular history.
Do not use for
Do not use this code for aphasia from trauma, tumors, degenerative neurologic disease, or other nonvascular causes. Check documentation if the cerebrovascular event is acute, because an active stroke code may be more appropriate.
Coding tip
Code the residual aphasia only when the provider documents a causal link to unspecified cerebrovascular disease.
