ICD-10 Code I97.51 – Accidental puncture and laceration of a circulatory system organ or structure during a circulatory system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.51 – Accidental puncture and laceration of a circulatory system organ or structure during a circulatory system procedure
What it is
This code identifies an accidental puncture or laceration of a blood vessel or other circulatory structure that occurs during a circulatory system procedure. Use it for a procedural complication, not for the original disease being treated.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include bleeding, hematoma, vessel injury, or the need for repair during or after the procedure.
When to use this code
Use I97.51 when the record clearly states that a circulatory system organ or structure was accidentally punctured or lacerated during a circulatory procedure. The complication must be procedure-related and documented by the clinician. If the note only mentions bleeding without an injury, check documentation before coding.
Do not use for
Do not use this code for intentional surgical incision, routine access, or a pre-existing vascular injury unrelated to the procedure. If the complication involves another organ system, choose the more specific code.
Coding tip
Link the complication to the procedure in the documentation before assigning I97.51.
