CPT® Code 77790

Code 77790 pertains to the supervision, handling, and loading of a radiation source during the process of brachytherapy, a form of internal radiation treatment. This procedure is primarily conducted by a radiation physicist, who plays a crucial role in ensuring the safe and effective delivery of radiation to the target area within the patient. The responsibilities associated with this code encompass several key activities, including the receipt of the radioelement, which involves careful handling, accounting, and logging of the inventory to maintain accurate records of the radiation sources used. Additionally, the radiation physicist is responsible for the care and maintenance of the instruments that are utilized to deliver the radiation source to the patient. This includes ensuring that all equipment is functioning correctly and is properly sterilized to prevent any risk of infection or complications. Furthermore, the loading of the radiation source to the designated target site is a critical step in the procedure, as it directly impacts the effectiveness of the treatment. It is important to note that the number of radiation sources used and their specific placement within the target area are integral components of code 77790. This code may be reported for each treatment session, unless the activities are already included in the application code for the radiation source itself.
