ICD-10 Code I69.99 – Other sequelae of unspecified cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.99 – Other sequelae of unspecified cerebrovascular disease
What it is
This code reports late effects from a prior cerebrovascular disease when the exact type is not specified. It captures residual problems that remain after the acute event has ended.
Clinical signs
Clinical features vary; refer to documentation. Residual neurologic deficits may include weakness, speech changes, gait problems, or cognitive impairment after a previous cerebrovascular event.
When to use this code
Use I69.99 when the record clearly states sequelae or late effects of a past cerebrovascular disease, but the original condition is not further identified. Code the residual deficit when documented, and confirm the history supports a prior event rather than an active stroke.
Do not use for
Do not use this code for an acute cerebrovascular accident or for symptoms without documentation of sequelae. If the provider identifies a specific stroke type or a different residual condition, choose the more precise code.
Coding tip
Look for wording such as “late effect,” “sequela,” or “residual from prior CVA” before assigning this code.
