    Clinical & Coding Specifications

    Clinical Context

    A 58-year-old male with end-stage biventricular heart failure is admitted for implantation of a total artificial heart (TAH) as a bridge to transplant. During the implant hospitalization the surgical team uses a variety of components, accessories, and disposable supplies specific to the total artificial heart system (for example, drive-line connectors, external controller interfaces, tubing mounts, or sensor adapters). A TAH component coded to L8698 is provided when a miscellaneous or non‑listed supply or accessory directly used with the implanted TAH is required but does not have its own HCPCS code. The clinical workflow includes intraoperative use of the accessory, immediate postoperative device testing, device programming at bedside by perfusion or biomedical engineering, and documentation of the specific accessory used in the operative note, implant log, and supply charge record. Billing for L8698 is submitted by the hospital supply department or durable medical equipment (DME) vendor depending on whether the item is stocked for inpatient implant versus outpatient durable accessory replacement. Typical sites of service include the operating room, post‑anesthesia care unit, cardiac intensive care unit, and outpatient durable medical equipment setting for later accessory replacement.
