The procedure described by CPT® Code 0404T involves the ablation of uterine fibroid(s) utilizing a transvaginal approach, guided by ultrasound and employing radiofrequency technology. Uterine fibroids, also known as leiomyomas, are non-cancerous tumors that develop within the smooth muscle layer of the uterus, referred to as the myometrium. These fibroids can lead to various symptoms, including abnormal uterine bleeding, pelvic pressure, and pain, and may also contribute to challenges with fertility. The use of ultrasound-guided radiofrequency ablation is recognized as a minimally invasive technique that effectively targets and destroys fibroid tissue through a process known as thermal fixation and coagulation necrosis, all while maintaining the structural integrity of the uterus. During the procedure, the cervix is dilated to allow for the insertion of a specialized probe that houses both an ultrasound transducer and a radiofrequency electrode. The ultrasound imaging is crucial for accurately identifying the fibroid's location and size, enabling the creation of a detailed graphic map of the treatment area. Based on the fibroid's characteristics, specific radiofrequency settings and safety parameters are established. Once these parameters are set, the radiofrequency electrode is carefully positioned within the fibroid, and thermal energy is applied under continuous ultrasound visualization until the fibroid is effectively reduced in size. If multiple fibroids are present, the procedure may be repeated as necessary before the transducer is finally removed.
