ICD-10 Code I97 – Intraoperative and Postprocedural Complications and Disorders of Circulatory System, Not Elsewhere Classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97 – Intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified
What it is
I97 is a category for circulatory system complications or disorders that happen during or after a procedure and are not classified elsewhere. Use it when the documentation points to a procedure-related vascular or circulatory problem, but a more specific code is unavailable.
Clinical signs
Clinical features vary; refer to documentation. Findings may include procedure-related bleeding, vascular injury, thrombosis, embolic events, or impaired circulation noted after surgery or an intervention.
When to use this code
Use I97 when the record clearly links the circulatory problem to an intraoperative or postprocedural event and the provider does not document a more specific diagnosis. It may apply after cardiac, vascular, or other procedures affecting circulation. Code the documented complication, not the routine aftercare.
Do not use for
Do not use this code for expected postoperative pain, routine recovery, or unspecified general complications without a circulatory system diagnosis. If the complication is described more specifically elsewhere, use the more precise code.
Coding tip
Check the operative note and discharge summary for the exact circulatory complication and whether it is documented as intraoperative or postprocedural.
