ICD-10 Code I69.80 – Unspecified sequelae of other cerebrovascular disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.80 – Unspecified sequelae of other cerebrovascular disease
What it is
This code identifies lingering effects after a prior cerebrovascular disease when the specific residual problem is not documented. Use it for sequelae from past vascular brain injury that remain after the acute event has ended.
Clinical signs
Clinical features vary; refer to documentation. Common sequelae may include persistent neurologic deficits such as weakness, speech difficulty, or coordination problems after a previous cerebrovascular event.
When to use this code
Use I69.80 when the record clearly links the current condition to a past cerebrovascular disease, but the residual effect is not specified. It is appropriate for follow-up care or chronic deficit management after the acute phase has resolved. Make sure the provider documents a sequela relationship.
Do not use for
Do not use this code for an active stroke or for symptoms without a documented prior cerebrovascular cause. If the residual deficit is specified elsewhere, check documentation for a more precise code.
Coding tip
Confirm both the prior cerebrovascular event and the current residual condition are documented before assigning this sequela code.
