ICD-10 Code I97.88 – Other intraoperative complications of the circulatory system, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.88 – Other intraoperative complications of the circulatory system, not elsewhere classified
What it is
This code identifies a circulatory system complication that occurs during surgery and does not fit a more specific ICD-10 category. Use it for intraoperative events involving the heart, vessels, or circulation when documentation supports a complication.
Clinical signs
Clinical features vary; refer to documentation. Records may note an unexpected intraoperative circulatory problem, such as hemodynamic instability or vascular injury, but the exact finding must be stated by the clinician.
When to use this code
Use I97.88 when the operative report or postoperative note clearly links the circulatory complication to the procedure and no more specific code applies. It is appropriate when the complication occurred during surgery, not as a routine expected event. If the record is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for complications that are better described by a more specific circulatory or surgical complication code. Do not assign it for preexisting cardiovascular disease, routine operative findings, or postoperative issues unrelated to the intraoperative event.
Coding tip
Code only when the provider documents a true intraoperative circulatory complication and supports the causal link to the procedure.
