CPT® Code 60605

The procedure described by CPT® Code 60605 involves the excision of a carotid body tumor, which is a benign neoplasm arising from the paraganglionic cells known as glomus tissue. These carotid bodies are strategically located at the bifurcation of the common carotid arteries, where they play a critical role in monitoring arterial blood composition, particularly in detecting variations in carbon dioxide and oxygen levels. When such changes occur, the carotid bodies trigger autonomic responses that adjust respiratory and heart rates to maintain homeostasis. The surgical intervention requires a careful incision in the neck, specifically over the area where the common carotid artery divides into the internal and external carotid arteries. During the procedure, vessel loops are employed to manage blood flow by controlling the proximal and distal blood vessels, ensuring a clear surgical field. The surgeon meticulously dissects the tumor from the common carotid artery and the surrounding tissues, extending the dissection superiorly while safeguarding the internal carotid artery. The excision is completed once the tumor is fully detached from all its attachments. It is important to note that CPT® Code 60605 is specifically used when a portion of the carotid artery is excised in conjunction with the tumor removal, distinguishing it from CPT® Code 60600, which is applicable when the tumor is excised without any involvement of the carotid artery.
