ICD-10 Code I97.6 – Postprocedural hemorrhage, hematoma and seroma of a circulatory system organ or structure following a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.6 – Postprocedural hemorrhage, hematoma and seroma of a circulatory system organ or structure following a procedure
What it is
I97.6 identifies bleeding, hematoma, or seroma that develops in a circulatory system organ or structure after a procedure. Use it when the complication is clearly documented as postprocedural and related to the prior intervention.
Clinical signs
Typical findings include postoperative swelling, bruising, localized pain, or evidence of internal bleeding at the procedural site. Clinical features vary; refer to documentation for the exact complication and affected circulatory structure.
When to use this code
Use I97.6 when the provider documents a postprocedural hemorrhage, hematoma, or seroma involving a blood vessel, heart, or other circulatory structure. It fits complication coding after surgery, catheter-based procedures, or similar interventions when the condition is not a routine postoperative finding.
Confirm that the complication is attributed to the procedure and that the record identifies the circulatory system site. If the documentation only says “bleeding” or “swelling,” check documentation before assigning this code.
Do not use for
Do not use this code for bleeding or hematoma unrelated to a procedure, or for complications in non-circulatory organs. Do not use it when the record does not link the finding to a prior procedure.
Coding tip
Code the specific postprocedural complication only when the provider clearly documents the causal relationship and affected circulatory structure.
