ICD-10 Code I97.648 – Postprocedural seroma of a circulatory system organ or structure following other circulatory system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.648 – Postprocedural seroma of a circulatory system organ or structure following other circulatory system procedure
What it is
This code identifies a seroma that develops after a procedure involving a circulatory system organ or structure. It describes a postoperative fluid collection, not an infection or bleeding complication.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include localized swelling, a fluctuant mass, or postoperative fluid accumulation near the procedure site, with imaging or exam confirming a seroma.
When to use this code
Use this code when the record clearly states a postprocedural seroma involving a circulatory system organ or structure after another circulatory system procedure. Code it when the surgeon documents the complication and links it to the prior procedure. Check documentation if the note only says postoperative swelling without confirming seroma.
Do not use for
Do not use this code for routine postoperative edema, hematoma, abscess, or wound infection. If the fluid collection is not documented as a seroma, check documentation.
Coding tip
Confirm both the seroma and the circulatory system procedure relationship before assigning I97.648.
