ICD-10 Code I69.921 – Dysphasia following unspecified cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.921 – Dysphasia following unspecified cerebrovascular disease
What it is
I69.921 identifies dysphasia that remains after an unspecified cerebrovascular disease. Use it when the record links the language problem to a prior stroke or other cerebrovascular event.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include impaired speech production, difficulty finding words, or reduced language comprehension after a cerebrovascular event.
When to use this code
Use this code when the provider documents dysphasia as a sequela of an unspecified cerebrovascular disease. It applies to residual language deficits after the acute event has passed. If the chart does not clearly connect the dysphasia to cerebrovascular disease, check documentation before coding.
Do not use for
Do not use this code for acute stroke symptoms without a documented residual deficit. Do not use it when the language disorder is unrelated to cerebrovascular disease or when the diagnosis is only suspected.
Coding tip
Verify that the note states both the residual dysphasia and its cerebrovascular cause before assigning I69.921.
