ICD-10 Code I69.923 – Fluency disorder following unspecified cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.923 – Fluency disorder following unspecified cerebrovascular disease
What it is
This code identifies a fluency problem, such as stuttering or disrupted speech flow, that occurs after an unspecified cerebrovascular disease. Use it when the record links the speech disturbance to a prior stroke-related condition.
Clinical signs
Clinical features vary; refer to documentation. You may see interrupted speech, abnormal rhythm, repeated sounds or syllables, and difficulty maintaining smooth verbal output after a cerebrovascular event.
When to use this code
Use this code when the provider documents a fluency disorder as a late effect of unspecified cerebrovascular disease. It is appropriate when the speech problem is clearly tied to the prior vascular event and not described as aphasia or another language disorder. Check documentation if the type of cerebrovascular disease is not specified.
Do not use for
Do not use this code for aphasia, dysarthria, or other speech disorders unless the record specifically identifies fluency disorder. Also avoid it when the cerebrovascular disease is not documented as the cause.
Coding tip
Confirm both the residual speech diagnosis and the cerebrovascular sequela linkage in the note before assigning I69.923.
