ICD-10 Code I97.810 – Intraoperative cerebrovascular infarction during cardiac surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.810 – Intraoperative cerebrovascular infarction during cardiac surgery
What it is
This code identifies a stroke-like infarction that occurs during cardiac surgery. Use it when the record states a cerebrovascular infarction happened intraoperatively, not as a preexisting condition.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include sudden neurologic deficit recognized during surgery, with provider documentation of cerebrovascular infarction and operative timing.
When to use this code
Use I97.810 when the surgeon or other qualified clinician documents an intraoperative cerebrovascular infarction during cardiac surgery. It applies when the event is explicitly tied to the operation and not described as a postoperative stroke or a prior history.
If the note only mentions neurologic change, altered mental status, or suspected embolic event, check documentation before coding. You should code this only when the infarction and cardiac-surgery context are clearly stated.
Do not use for
Do not use this code for preoperative stroke, postoperative cerebrovascular accident, or nonspecific neurologic symptoms without documented infarction. Check documentation if the event is not clearly intraoperative.
Coding tip
Link the diagnosis to the operative report or physician note showing both timing and cardiac-surgery context before assigning I97.810.
