    Clinical & Coding Specifications

    Clinical Context

    A typical patient is a 55-year-old adult with refractory overactive bladder or urgency urinary incontinence who has undergone percutaneous tibial nerve stimulation (PTNS) or is using a transcutaneous/external tibial nerve stimulation device at home. The clinician (urologist, urogynecologist, pelvic floor physical therapist, or neuromodulation-trained nurse) prescribes a reusable external tibial nerve stimulator with disposable monthly supplies such as conductive socks, gel pads, or electrodes. The patient obtains the monthly accessory kit to maintain skin contact, conductivity, and hygiene.

    Clinical workflow: The clinician documents the diagnosis and the need for ongoing monthly replacement supplies in the patient’s chart during a follow-up visit or a device training session. The clinician issues an order or prescription referencing supplies for one month. The supplier or durable medical equipment provider dispenses the A4545 supply kit, records the prescription/order, and bills the payer. The patient uses the supplies at home with the external tibial nerve stimulator during scheduled treatment sessions, with return visits or remote monitoring as clinically indicated.
