CPT® Code 61611

Add-On Code

Transection or ligation, carotid artery in petrous canal; without repair (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 61611 involves the transection or ligation of the carotid artery located in the petrous canal, which is a bony structure within the skull that houses the inner ear and the auditory nerve. This procedure is performed without any repair of the artery following the transection or ligation. In simpler terms, the physician either cuts (transects) or ties off (ligates) the carotid artery in the area situated between the brain and the temple. This action is typically undertaken in specific clinical scenarios where it is necessary to manage vascular issues or complications related to the carotid artery, ensuring that the procedure is performed with precision to minimize risks associated with blood flow disruption in this critical area. It is important to note that this code is listed separately and is intended to be used in conjunction with a primary procedure, indicating that it is an additional intervention rather than a standalone operation.
