ICD-10 Code I97.621 – Postprocedural hematoma of a circulatory system organ or structure following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.621 – Postprocedural hematoma of a circulatory system organ or structure following other procedure
What it is
I97.621 identifies a hematoma that develops in a circulatory system organ or structure after a procedure. Use it when documentation links the bleeding collection directly to the prior intervention.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include localized swelling, bruising, pain, or a mass at the procedural site, with imaging or exam confirming a postoperative blood collection.
When to use this code
Use this code when the provider documents a postprocedural hematoma involving a blood vessel, heart, or other circulatory structure after a non-specified procedure. It fits cases where the hematoma is a complication of the procedure, not an expected postoperative bruise.
Code it only when the record clearly states the hematoma is due to the procedure and the affected circulatory structure is identified. Check documentation if the site, cause, or relationship to surgery is unclear.
Do not use for
Do not use it for routine postoperative bruising, unspecified bleeding, or hematomas in non-circulatory sites. Check documentation if the complication is better described by another postprocedural code.
Coding tip
Confirm both the circulatory system structure and the procedural cause before assigning I97.621.
