ICD-10 Code I69.3 – Sequelae of cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.3 – Sequelae of cerebral infarction
What it is
This code identifies ongoing conditions that remain after a prior cerebral infarction, such as stroke-related deficits. It is used for late effects, not for the acute infarction itself.
Clinical signs
Clinical features vary; refer to documentation. Common sequelae may include persistent weakness, speech or language impairment, or gait problems after a documented cerebral infarction.
When to use this code
Use I69.3 when the record clearly states a current deficit is due to an old cerebral infarction. You should code the residual condition and link it to the prior stroke when documentation supports that relationship. If the note describes only a history of stroke without a current effect, this code is not appropriate.
Do not use for
Do not use this code for an acute cerebral infarction or for a past stroke with no remaining deficit. Check documentation if the provider does not specify a sequela or residual effect.
Coding tip
Look for wording such as “late effect,” “residual,” or “due to prior stroke” before assigning I69.3.
