Postproc seroma of a circ sys org following a cardiac cath

This code signifies the development of a seroma, a collection of serous fluid, occurring after a cardiac catheterization procedure. The seroma is specifically located within or adjacent to an organ or structure of the circulatory system. This is a postprocedural complication.

Use this code when documentation clearly indicates a seroma formed as a direct result of a cardiac catheterization, affecting a circulatory system component. This typically involves fluid accumulation at the access site (e.g., femoral, radial) or within the mediastinum following the procedure. Documentation should specify the seroma and its relationship to the recent cardiac catheterization.

• Always sequence this code after the primary reason for the encounter or the cardiac catheterization procedure code (if applicable).
• Distinguish from hematoma (I97.63x) or hemorrhage (I97.62x); seroma implies serous fluid, not blood.
• Ensure documentation specifies "seroma" and its postprocedural nature following a cardiac catheterization.
