CPT® Code 58346

The CPT® Code 58346 refers to the procedure involving the insertion of Heyman capsules for clinical brachytherapy. Heyman capsules are specialized devices that are either metallic or plastic and contain a specific amount of radioactive material, typically ranging from 5 to 10 mg of radium. This procedure is primarily utilized for the intracavity radiation treatment of malignant neoplasms located in the uterus. The insertion of these capsules allows for the delivery of low-dose radiation directly to the tumor, which is crucial in minimizing the exposure and potential damage to surrounding healthy tissues. The physician plays a vital role in determining the precise number and strategic placement of the Heyman capsules within the uterus, ensuring that they are positioned effectively in relation to the tumor. This targeted approach is essential for optimizing treatment outcomes in patients with neoplasms of the uterine fundus.
