Benign neoplasm of carotid body

This code signifies a non-cancerous tumor originating from the carotid body, a chemoreceptor located at the bifurcation of the common carotid artery. These tumors, often called paragangliomas or chemodectomas, are typically slow-growing and can present as a palpable neck mass. While benign, they can cause symptoms due to compression of surrounding structures or, less commonly, secrete catecholamines.

Use this code when documentation clearly identifies a benign neoplasm specifically of the carotid body. This diagnosis is often confirmed through imaging studies (e.g., MRI, CT angiography) and sometimes biopsy. Support for this code includes pathology reports confirming benign paraganglioma or chemodectoma of the carotid body.

• Ensure the documentation specifies "benign" and explicitly links the neoplasm to the "carotid body" to avoid miscoding.
• Do not confuse this with malignant carotid body tumors, which are coded differently.
• Code any associated symptoms (e.g., dysphagia, hoarseness) separately, if documented.
