Add-On Code

Transcatheter placement of radiation delivery device for subsequent coronary intravascular brachytherapy (List separately in addition to code for primary procedure)

The CPT® Code 92974 refers to the transcatheter placement of a radiation delivery device specifically designed for subsequent coronary intravascular brachytherapy. This procedure is performed in conjunction with a cardiac catheterization, which is a separate and reportable procedure. The primary purpose of this intervention is to address issues related to primary coronary stenosis or to manage restenosis that may occur following the placement of a coronary artery stent. During the procedure, a guidewire is initially placed within the coronary artery, which serves as a pathway for the catheter that carries the brachytherapy delivery device. This device is essentially a wire, often referred to as a seed train or ribbon, that is imbued with radiation. Once the catheter is accurately positioned at the site of the stenosis, the radiation is delivered to the affected area to help inhibit the growth of tissue that could lead to further narrowing of the artery. After the radiation treatment is administered, both the brachytherapy delivery device and the catheter are removed. Following this, the physician may proceed with additional therapeutic interventions, such as angioplasty, atherectomy, or stenting, to further treat the coronary artery stenosis or restenosis, ensuring comprehensive management of the patient's condition.
