CPT® Code 0739T

1. Indications

The procedure described by CPT® Code 0739T is indicated for the treatment of malignant prostate tissue. This technique is specifically utilized for patients diagnosed with prostate cancer, where traditional treatment options may not be suitable or effective. The use of magnetic field induction for ablation is particularly relevant for tumors that are localized within the prostate and can benefit from targeted thermal destruction while minimizing damage to surrounding healthy tissue.

• Malignant Prostate Tissue The primary indication for this procedure is the presence of malignant tumors within the prostate gland, which require intervention to reduce tumor size or eliminate cancerous cells.

2. Procedure

The procedure for CPT® Code 0739T involves several critical steps to ensure effective ablation of malignant prostate tissue. Each step is meticulously planned and executed to maximize patient safety and treatment efficacy.

• Step 1: Preoperative Planning The procedure begins with preoperative imaging, typically using MRI, to identify the precise location of the malignant tissue within the prostate. This imaging is essential for planning the treatment and determining the optimal placement of catheters for temperature monitoring.
• Step 2: Catheter Placement Under ultrasound guidance, the physician places transperineal needles or catheters into the previously identified target regions of the prostate. These catheters are designed to hold temperature sensors that will monitor the tissue during the ablation process.
• Step 3: Bladder Irrigation To protect the bladder during the procedure, bladder irrigation is initiated. This involves the infusion of fluid into the bladder to ensure that it is adequately flushed and to prevent any potential complications during the injection of the nanoparticle suspension.
• Step 4: Nanoparticle Injection Once the catheters are in place and bladder irrigation is established, a suspension of magnetic nanoparticles is injected into the targeted prostate tissue. This step is crucial as the nanoparticles will be activated by the magnetic field to facilitate tumor ablation.
• Step 5: Temperature Sensor Placement After the nanoparticle injection, temperature sensors are placed through the catheters. These sensors are essential for monitoring the temperature of the tissue during the ablation process to ensure it remains within the target range for effective treatment.
• Step 6: Activation of Magnetic Field The magnetic field is then activated, typically for a duration of approximately one hour. During this time, the physician continuously monitors the tissue temperatures to ensure they remain within the desired range for successful ablation of the malignant tissue.

3. Post-Procedure

Following the completion of the ablation procedure, patients are monitored for any immediate post-procedural effects. It is essential to assess the patient's comfort level and any potential complications that may arise from the procedure. The physician will typically provide instructions regarding post-procedure care, which may include recommendations for hydration, activity restrictions, and follow-up appointments to evaluate the effectiveness of the treatment. Additionally, monitoring for any signs of infection or adverse reactions is crucial in the days following the procedure to ensure patient safety and recovery.
