Postprocedural seroma of the spleen fol proc on spleen

This code signifies the development of a seroma, a collection of serous fluid, specifically within the spleen as a direct complication of a prior surgical or interventional procedure performed on the spleen itself. It indicates a localized fluid accumulation that is not purulent (infected) or hemorrhagic.

Use this code when documentation clearly identifies a seroma located within the spleen that is a sequela of a splenic procedure. This typically requires imaging reports (e.g., ultrasound, CT) confirming the seroma and operative notes detailing the preceding splenic intervention.

• Ensure the seroma is explicitly documented as postprocedural and located within the spleen.
• Do not use for seromas in other anatomical sites or for non-postprocedural splenic cysts/collections.
• Sequence this code after the primary reason for the encounter if the seroma is being treated or evaluated.
