CPT® Code 64566

Posterior tibial neurostimulation is a therapeutic procedure aimed at managing conditions such as overactive bladder, urge incontinence, and frequent urination in patients who have not responded to other treatment options. This procedure targets the posterior tibial nerve, which is a branch of the sacral nerve plexus, a network of nerves that play a crucial role in bladder and pelvic floor function. By utilizing neuromodulation techniques, the procedure involves sending mild electrical impulses to stimulate the sacral nerve plexus, which can enhance the control and function of voiding. During the procedure, the patient's foot is positioned comfortably, and the area above the ankle, where the tibial nerve is located, is thoroughly cleansed to ensure a sterile environment. A fine-needle electrode is then carefully inserted near the nerve, allowing for the delivery of low-voltage electrical stimulation. This stimulation is administered at a prescribed voltage for a specific duration, tailored to the patient's needs. The CPT® Code 64566 specifically reports a single treatment session of this procedure, with most patients typically undergoing weekly sessions over a course of 10 to 12 weeks to achieve optimal results.
