ICD-10 Code I97.622 – Postprocedural seroma of a circulatory system organ or structure following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.622 – Postprocedural seroma of a circulatory system organ or structure following other procedure
What it is
I97.622 identifies a seroma that develops after a procedure involving a circulatory system organ or structure. Use it when documentation shows a postoperative fluid collection related to that vascular or cardiac site.
Clinical signs
Typical findings include localized swelling, a fluctuant mass, or persistent fluid accumulation at the procedure site. Clinical features vary; refer to documentation for confirmation that the collection is a seroma and not infection or hematoma.
When to use this code
Use this code when the record clearly links the seroma to a prior procedure on a circulatory system organ or structure. It fits postoperative fluid collections after vascular or cardiac procedures when the provider documents seroma. Check documentation if the site, cause, or procedure type is unclear.
Do not use for
Do not use it for seromas after non-circulatory procedures or for unspecified postoperative fluid collections. If the note describes infection, hematoma, or another complication instead, code that documented condition.
Coding tip
Confirm both the postoperative nature and the circulatory system site before assigning I97.622.
