CPT code 64596: Peripheral nerve array, one integrated array2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 64596 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 64596 covers

This procedure places or replaces one percutaneous electrode array at a peripheral nerve as part of a system with an integrated neurostimulator. It is typically performed by a physician treating chronic pain or another condition managed with peripheral nerve stimulation, often in a procedural or surgical facility. Imaging guidance is included when performed. This code distinguishes the integrated system from procedures using a separate electrode array and pulse generator.

Medicare assigns this CPT Category I service carrier-priced status: there is no national physician fee schedule payment, and the Medicare Administrative Contractor sets payment for each claim. Report one unit for the single array; report 64597 for each additional array. The service has a 10-day global period, with related postoperative visits during that period included. Standard multiple-procedure reduction applies when multiple procedures are performed in the same session. Bilateral adjustment is inappropriate, and Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.
