CPT® Code 0818T

Revision or removal of integrated neurostimulation system for bladder dysfunction, including analysis, programming, and imaging, when performed, posterior tibial nerve; subcutaneous

The CPT® Code 0818T refers to the procedure involving the revision or removal of an integrated neurostimulation system specifically designed for bladder dysfunction. This procedure encompasses several critical components, including the analysis, programming, and imaging of the neurostimulator when performed. The integrated neurostimulator is typically placed on the posterior tibial nerve, which is a branch of the sciatic nerve. This placement is intended to treat conditions such as overactive bladder or intractable urge incontinence by delivering retrograde neuromodulation to the sacral nerve plexus, which plays a vital role in controlling bladder function and lower urinary tract activity. During the procedure, the physician prepares the patient by marking the incision site and making an incision over the previous surgical site. The subcutaneous pocket is then opened to access the neurostimulator device. The device may be tested for its functionality and proper positioning, allowing for adjustments or complete removal if necessary. This procedure is particularly relevant when the neurostimulator has ceased to provide effective treatment, necessitating either its removal or revision to restore its efficacy. The final steps involve closing the fascia or irrigating the subcutaneous pocket and suturing the skin in layers to ensure proper healing.
