Postproc seroma of a circ sys org following other procedure

This code signifies the development of a seroma, which is a collection of serous fluid, occurring after a surgical or interventional procedure performed on an organ or structure within the circulatory system. This seroma is a complication directly attributable to the prior intervention, excluding those specifically following cardiac or vascular implant procedures.

Apply this code when documentation indicates a patient has developed a seroma in proximity to a circulatory system organ or structure following a procedure other than the insertion of a cardiac or vascular implant. Examples include seroma after carotid endarterectomy, peripheral bypass graft, or renal artery angioplasty. The physician's notes should clearly identify the seroma as a postprocedural complication and specify the affected circulatory system site.

• Ensure the seroma is explicitly linked to a circulatory system procedure and not a general surgical site.
• Distinguish this from seromas following cardiac or vascular implant procedures, which have their own specific codes.
• Always sequence this code after the code for the underlying complication (e.g., T81.89XA for other complications of procedures, not elsewhere classified, if applicable) or as a secondary diagnosis if the seroma is not the primary reason for the encounter.
