Official Description

Hyperthermia generated by intracavitary probe(s)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Hyperthermia generated by intracavitary probe(s) is a specialized medical procedure aimed at increasing the temperature of tumor cells while minimizing damage to surrounding healthy tissue. This technique utilizes probes that are inserted into body cavities, where they generate heat through various methods such as microwave, radiofrequency, or ultrasound. The fundamental principle behind this procedure is that tumor cells exhibit a higher sensitivity to elevated temperatures compared to normal cells. By raising the temperature of the tumor cells, the procedure can enhance the efficacy of concurrent treatments like radiation and chemotherapy, as well as potentially stimulate the immune system to target and destroy abnormal cells more effectively. Intracavitary hyperthermia is particularly applicable for tumors that are accessible through natural body openings, including the vagina for cervical and uterine tumors, the anus for prostate tumors, the nose for nasopharyngeal tumors, and the mouth for esophageal tumors. During the procedure, a specially designed probe that conforms to the shape of the cavity is carefully inserted, with its placement often confirmed through imaging techniques such as x-ray or ultrasound. Once positioned, a heat source is introduced into the probe, elevating the temperature of the targeted area to the predetermined therapeutic level. Upon completion of the hyperthermia session, the probe and heat source are removed from the body cavity. This CPT® code encompasses not only the hyperthermia treatment itself but also includes the management of the treatment course, physics planning, insertion of temperature sensors, and the utilization of heat-generating devices.

1. Indications

The procedure of hyperthermia generated by intracavitary probe(s) is indicated for various tumor types that can be accessed through natural body orifices. The following conditions are explicitly mentioned as suitable for this treatment:

  • Cervical and Uterine Tumors - Tumors located in the vagina or cervix that can benefit from localized heat treatment.
  • Prostate Tumors - Tumors situated in the prostate gland, accessible via the anus for targeted hyperthermia.
  • Nasopharyngeal Tumors - Tumors found in the nasopharynx, which can be treated through the nasal cavity.
  • Esophageal Tumors - Tumors located in the esophagus, which can be accessed through the mouth for hyperthermia treatment.

2. Procedure

The procedure for hyperthermia generated by intracavitary probe(s) involves several critical steps to ensure effective treatment. Each step is designed to maximize the therapeutic benefits while ensuring patient safety.

  • Step 1: Preparation and Planning - Prior to the procedure, a comprehensive treatment plan is developed, which includes physics planning to determine the appropriate parameters for heat application. This step may involve imaging studies to assess the tumor's location and size, as well as the surrounding anatomy.
  • Step 2: Insertion of the Probe - A specially designed intracavitary probe is inserted into the appropriate body cavity. The probe is contoured to fit the specific shape of the cavity, ensuring optimal contact with the tumor. Placement of the probe is often verified using imaging techniques such as x-ray or ultrasound to confirm accurate positioning.
  • Step 3: Heat Application - Once the probe is correctly positioned, a heat-generating source is introduced into the probe. This source may utilize microwave, radiofrequency, or ultrasound technology to elevate the temperature of the targeted tumor cells. The temperature is carefully monitored to achieve the desired therapeutic level while protecting surrounding healthy tissue.
  • Step 4: Monitoring and Adjustment - Throughout the procedure, the patient's response to the heat application is closely monitored. Adjustments may be made to the heat source or duration of treatment based on real-time feedback and temperature readings from inserted sensors.
  • Step 5: Conclusion of Treatment - At the end of the hyperthermia session, the heat source is removed from the probe, followed by the careful extraction of the probe from the body cavity. Post-procedure assessments may be conducted to evaluate the immediate effects of the treatment.

3. Post-Procedure

After the hyperthermia treatment, patients may require monitoring for any immediate post-procedure effects. Expected recovery may vary based on individual patient factors and the extent of the procedure. Patients are typically advised to follow up with their healthcare provider to assess the treatment's effectiveness and to discuss any further management or additional therapies that may be necessary. It is essential to monitor for any potential complications, such as discomfort or localized reactions at the site of probe insertion. Comprehensive post-procedure care instructions will be provided to ensure optimal recovery and ongoing management of the underlying condition.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
