CPT® Code 60600

The procedure described by CPT® Code 60600 involves the excision of a carotid body tumor, which is a benign neoplasm located at the bifurcation of the common carotid arteries. The carotid bodies are specialized clusters of paraganglionic cells, known as glomus tissue, that play a critical role in monitoring arterial blood composition. They detect variations in blood gases, particularly elevated carbon dioxide levels and decreased oxygen levels, and trigger autonomic responses that adjust respiratory and heart rates to maintain homeostasis. During the excision procedure, the surgeon makes an incision in the neck over the area where the common carotid artery divides into the internal and external carotid arteries. The surgical approach requires careful dissection to separate the tumor from the surrounding vascular structures, particularly the internal carotid artery, ensuring that the artery remains intact. This procedure is specifically coded as 60600 when the excision of the carotid artery is not necessary. In contrast, if a portion of the carotid artery must be removed to facilitate the tumor excision, CPT® Code 60605 should be utilized instead.
