ICD-10 Code I69.821 – Dysphasia following other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.821 – Dysphasia following other cerebrovascular disease
What it is
I69.821 identifies dysphasia that remains after a cerebrovascular disease event. Use it when the record shows ongoing language impairment linked to prior stroke or another cerebrovascular condition.
Clinical signs
Clinical features vary; refer to documentation. Common findings include impaired word finding, reduced verbal fluency, or difficulty understanding or expressing language after a cerebrovascular event.
When to use this code
Use this code for residual dysphasia documented as a sequela of a prior cerebrovascular disease, not for an acute event. The chart should clearly connect the language deficit to the earlier cerebrovascular condition. If the note says aphasia or another communication disorder instead, code what is documented.
Do not use for
Do not use it for acute stroke symptoms, transient speech disturbance, or dysphasia without a documented cerebrovascular cause. Check documentation if the residual relationship is unclear.
Coding tip
Verify that the provider documents both the residual dysphasia and the prior cerebrovascular disease link before assigning I69.821.
