ICD-10 Code I97.811 – Intraoperative cerebrovascular infarction during other surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.811 – Intraoperative cerebrovascular infarction during other surgery
What it is
This code identifies a stroke-like infarction that occurs during a surgical procedure other than cardiac or vascular surgery. It reflects a cerebrovascular injury recognized intraoperatively, not a preexisting stroke.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include sudden neurologic change during surgery, such as altered consciousness, weakness, speech disturbance, or new focal deficits noted by the operative team.
When to use this code
Use I97.811 when the record clearly states an intraoperative cerebrovascular infarction occurred during another surgery and the surgeon documents it as a complication. You should link the event to the operative episode, not to a prior history of stroke. If the documentation only says “neurologic change” or “possible stroke,” check documentation.
Do not use for
Do not use this code for a stroke that happened before surgery, after surgery, or for transient neurologic symptoms without infarction. It is also not for cerebrovascular infarction during cardiac or vascular surgery unless the record specifically supports this code.
Coding tip
Confirm that the infarction was documented as intraoperative and related to “other surgery” before assigning I97.811.
