CPT® Code 61715

Magnetic resonance image guided high intensity focused ultrasound (MRgFUS), stereotactic ablation of target, intracranial, including stereotactic navigation and frame placement, when performed

The CPT® Code 61715 refers to a specialized medical procedure known as Magnetic Resonance Image Guided High Intensity Focused Ultrasound (MRgFUS). This non-invasive technique is utilized for the stereotactic ablation of intracranial targets, specifically aimed at treating movement disorders such as essential tremor and Parkinson’s disease that have not responded to conventional medical treatments. The procedure employs advanced imaging technology to precisely target and ablate lesions within the brain, thereby alleviating symptoms associated with these disorders. Prior to the procedure, the patient's scalp is prepared by shaving and inspecting for any scars or lesions that may interfere with the transmission of ultrasound waves. A stereotactic frame is then affixed to the patient's head, ensuring accurate positioning of the brain within the treatment area. The use of a silicone membrane filled with chilled, degassed water serves to protect external tissues and bone from potential burns caused by the ultrasound energy. Throughout the procedure, the patient remains awake, allowing for real-time feedback to the surgeon, which is crucial for monitoring the effectiveness of the treatment. The integration of magnetic resonance thermometry imaging provides continuous temperature monitoring, ensuring that the targeted lesions are adequately treated while minimizing damage to surrounding healthy tissue.
