CPT® Code 77610

Hyperthermia generated by interstitial probe(s) is a specialized medical procedure aimed at elevating the temperature of tumor cells while minimizing damage to the surrounding healthy tissue. This technique utilizes interstitially placed applicators or probes that generate heat through various methods, including microwave, radiofrequency, or ultrasound energy. The fundamental principle behind this procedure is that tumor cells exhibit a higher sensitivity to increased temperatures compared to normal cells. By raising the temperature of the tumor cells, the procedure can enhance the efficacy of concurrent treatments such as radiation and chemotherapy, as well as potentially stimulate the immune system's components that contribute to the destruction of abnormal cells. Interstitial hyperthermia therapy is particularly beneficial for treating tumors located deep within the body, such as those found in the lungs or abdominal organs. During the procedure, the patient is placed under anesthesia, and the applicators or probes are carefully inserted into the tumor with the assistance of imaging techniques like x-ray or ultrasound guidance. Once positioned, a heat source is introduced into the applicators or probes, allowing the targeted area to be heated to a predetermined temperature. Following the treatment session, the probes are removed. The CPT® Code 77610 specifically reports interstitial hyperthermia therapy utilizing five or fewer interstitial applicators, while CPT® Code 77615 is designated for cases involving more than five applicators or probes.
