Postproc seroma of an endo sys org following other procedure

This code signifies the development of a seroma, a collection of serous fluid, occurring after a surgical or invasive procedure performed on an endocrine system organ or structure. This condition is a known post-operative complication, distinct from hematoma or infection.

Apply this code when documentation clearly indicates a seroma formed following a procedure on an endocrine organ (e.g., thyroidectomy, adrenalectomy, parathyroidectomy), and the procedure itself is not specified as a "transplant" or "graft." Supporting documentation should describe the presence of a seroma and its anatomical location within the endocrine system.

• Ensure the documentation specifies "seroma" and not another fluid collection like hematoma or abscess.
• Verify the affected organ is part of the endocrine system.
• Sequence this code after the primary diagnosis for which the original procedure was performed, if applicable, or as the primary diagnosis if the seroma is the reason for the encounter.
