ICD-10 Code I69.398 – Other sequelae of cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.398 – Other sequelae of cerebral infarction
What it is
This code identifies residual effects that remain after a cerebral infarction, when the specific late effect does not fit a more exact sequela code. Use it for ongoing problems caused by a prior stroke, not for the acute event.
Clinical signs
Clinical features vary; refer to documentation. You may see persistent neurologic deficits, such as weakness, speech difficulty, sensory loss, or other lasting impairments attributed to an old cerebral infarction.
When to use this code
Use this code when the record clearly states a sequela of prior cerebral infarction and the residual condition is described only as “other” or is not captured by a more specific code. It is appropriate for follow-up visits focused on chronic aftereffects. Confirm that the provider links the current deficit to the old infarct.
Do not use for
Do not use this code for an acute ischemic stroke or for symptoms without documentation tying them to a previous infarction. Check documentation if the residual effect is better described by a more specific I69 code.
Coding tip
Code the residual manifestation first when required, and use I69.398 only when the sequela is documented but not otherwise specified.
