Summary & Overview
CPT 64585: Revision or Removal of Peripheral Nerve Neurostimulator Electrode Array
CPT code 64585 denotes the surgical revision or removal of a neurostimulator electrode array on a peripheral nerve. This procedure is commonly performed when an implanted peripheral nerve stimulator malfunctions or when infection develops at the implant site. Nationally, procedures involving implanted neurostimulation hardware carry clinical and policy significance because of their implications for device management, infection control, and post-operative care.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis provides payer coverage context and common administrative considerations associated with claims for device revision or removal.
Readers will find an overview of the clinical context for 64585, typical sites of service, and the common reasons for performing the procedure.

Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with a peripheral nerve neurostimulator implanted for refractory neuropathic pain presents with increasing pocket pain, erythema, and purulent drainage three weeks after a generator change. Examination and device interrogation demonstrate rising impedances and nonphysiologic stimulation patterns consistent with lead malfunction and local infection. The clinician schedules a procedure to revise or remove the peripheral nerve electrode array. The clinical workflow includes preoperative antibiotic administration per facility protocol, informed consent documenting device malfunction and infection risk, perioperative anesthesia (local with sedation or general anesthesia depending on patient factors), surgical exploration of the lead and generator pocket, careful explantation or partial removal of the electrode array with irrigation and debridement, device cultures sent to microbiology, hemostasis, and wound closure. Postoperative plans include wound care, targeted antibiotics based on culture results, documentation of device components removed in the operative report, and coordination with the implanting service for future reimplantation if indicated.
