Encounter for prophylactic removal of other organ

This diagnosis code signifies a patient encounter for the surgical removal of an organ or body part to prevent the future development of a disease, when the organ is not a breast or ovary. This is a prophylactic measure taken due to a high risk of disease, rather than for an existing condition.

Apply this code when a patient undergoes a procedure like a prophylactic colectomy for familial adenomatous polyposis, a prophylactic thyroidectomy for MEN2 syndrome, or a prophylactic gastrectomy for hereditary diffuse gastric cancer. It is used when the primary reason for the encounter is the preventative removal of an organ other than the breast or ovary.

• Always sequence this code as the primary diagnosis when the prophylactic removal is the sole reason for the encounter.
• Code any underlying genetic predisposition or high-risk condition as a secondary diagnosis.
• Ensure the operative report clearly documents the prophylactic nature of the surgery and the specific organ removed.
