CPT code 64555 represents surgical implantation of a peripheral nerve neurostimulator system with electrodes placed around a selected peripheral nerve and connected to an implanted generator. This procedure is a targeted neuromodulation approach used for management of refractory pain and select neurologic conditions; its use has implications for device coverage, durable medical equipment policy, and surgical care pathways nationwide. Key national payers typically included in coverage reviews are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find a concise overview of the clinical procedure and typical sites of care, an explanation of which payers commonly adjudicate claims for this service, and the types of analyses that inform coverage and reimbursement decisions, including benchmarks for utilization, coding nuances, and relevant policy trends. The publication covers national benchmarking context, payer policy summaries where available, and clinical considerations relevant to coding and billing for implantable peripheral nerve stimulation. Data not included in the input are noted as unavailable; the focus remains on clarifying the code purpose, service setting, and the payer landscape for stakeholders involved in surgical neuromodulation services.
