What 64597 covers

Code 64597 identifies an additional percutaneous electrode array inserted or replaced for peripheral nerve stimulation, beyond the array represented by primary code 64596. It applies when the procedure includes more than one array; the initial array is represented by 64596. The clinician performing the implantation reports this service as an add-on to that primary procedure. Documentation should support the additional array and its placement or replacement.

Medicare assigns carrier-priced status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. Report 64597 only with its primary procedure, 64596; Medicare treats the add-on payment within that procedure's global period. Report one unit for each additional electrode array, not for the initial array.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
