Postproc seroma of the spleen following other procedure

This code describes the formation of a seroma, a collection of serous fluid, specifically located in the spleen, that develops as a complication following a surgical or invasive procedure other than a splenectomy. It indicates a post-operative fluid accumulation within or adjacent to the splenic capsule.

Use this code when documentation clearly states a seroma of the spleen developed after a surgical intervention not involving the spleen itself (e.g., abdominal surgery near the spleen). The medical record should specify the location as the spleen and confirm its postprocedural etiology.

• Ensure the documentation specifies the spleen as the anatomical site of the seroma.
• Distinguish from hematoma (blood collection) or abscess (pus collection); this code is specific to serous fluid.
• This code requires an additional code to identify the underlying procedure that led to the seroma.
