ICD-10 Code I69.823 – Fluency disorder following other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.823 – Fluency disorder following other cerebrovascular disease
What it is
This code identifies a fluency problem, such as trouble speaking smoothly, that occurs after a cerebrovascular disease other than stroke. Use it when the speech change is a late effect of a documented vascular brain condition.
Clinical signs
Clinical features may include hesitant speech, disrupted rhythm, or difficulty producing words fluently. Clinical features vary; refer to documentation and confirm the fluency disorder is linked to the prior cerebrovascular condition.
When to use this code
Use I69.823 when the record clearly states fluency disorder as a sequela of another cerebrovascular disease. It applies to residual speech impairment after the acute event has passed, not to a new or unrelated speech complaint. Check documentation for the exact vascular diagnosis and the causal link.
Do not use for
Do not use this code for acute cerebrovascular symptoms, unspecified speech disturbance, or fluency problems without a documented cerebrovascular cause. Check documentation if the record does not identify a qualifying late effect.
Coding tip
Code the residual fluency disorder and the underlying cerebrovascular condition only when both are documented and the relationship is stated.
