ICD-10 Code I69.90 – Unspecified sequelae of unspecified cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.90 – Unspecified sequelae of unspecified cerebrovascular disease
What it is
This code identifies lingering effects from a prior cerebrovascular disease when the exact original event is not specified. Use it for residual conditions that remain after the acute phase has ended.
Clinical signs
Clinical features vary; refer to documentation. Residual weakness, speech difficulty, gait problems, or cognitive changes may be noted after a prior cerebrovascular event.
When to use this code
Use this code when the record clearly documents a sequela of cerebrovascular disease but does not identify the type of stroke or other cerebrovascular disorder. It is appropriate for ongoing deficits attributed to a past event, not for the acute episode. Check documentation for the specific residual condition.
Do not use for
Do not use it for acute cerebrovascular disease or for a documented type of stroke with a more specific sequela code. Do not use when the residual effect is unrelated or the record does not support a sequela.
Coding tip
Code the residual deficit first when documented, and assign I69.90 only when the prior cerebrovascular disease is unspecified.
