ICD-10 Code I97.638 – Postprocedural hematoma of a circulatory system organ or structure following other circulatory system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.638 – Postprocedural hematoma of a circulatory system organ or structure following other circulatory system procedure
What it is
This code identifies a hematoma that develops in a circulatory system organ or structure after a different circulatory system procedure. It reflects an operative complication, not the original vascular disease.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include localized swelling, bruising, pain, or a documented postoperative blood collection at the procedure site.
When to use this code
Use I97.638 when the provider documents a postprocedural hematoma involving a circulatory system organ or structure after another circulatory system procedure. Apply it for postoperative vascular bleeding collections tied to the procedure, when the record supports the complication.
Code this only when the hematoma is clearly described as a complication of the procedure. Check documentation if the note does not specify the site, relationship to surgery, or whether the finding is expected versus abnormal.
Do not use for
Do not use this code for a preexisting hematoma, traumatic hematoma, or bleeding unrelated to a circulatory system procedure. Check documentation if the hematoma follows a nonvascular operation.
Coding tip
Link the hematoma to the specific prior circulatory system procedure in the record before assigning I97.638.
