Summary & Overview
CPT 64595: Revision or Removal of Neurostimulator Pulse Generator
CPT code 64595 represents surgical revision or removal of a peripheral, sacral, or gastric neurostimulator pulse generator or receiver that was placed in a surgically created pocket and is connected to an electrode array. This code matters nationally because implanted neurostimulation therapies are an expanding modality for chronic pain and functional disorders, and device maintenance or removal procedures are common drivers of episodic surgical resource use. Payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn what CPT code 64595 denotes, the clinical contexts that prompt generator/receiver revision or removal, and the typical service setting for these procedures. The publication summarizes national reimbursement and billing considerations, common modifier usage, and benchmarks where available. It also outlines policy and coverage themes relevant to payers and facilities that manage implanted neurostimulator systems. Data not available in the input will be noted explicitly where applicable.
Billing Code Overview
CPT code 64595 describes the revision or removal of a peripheral, sacral, or gastric neurostimulator pulse generator or receiver. This procedure applies to implanted neurostimulator systems that required a surgically created pocket for the pulse generator or receiver and that include a physical connection between the electrode array and the pulse generator or receiver.

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with chronic refractory neuropathic pelvic pain previously implanted with a sacral neurostimulator presents with declining battery function and recurrent loss of analgesic benefit. The patient is scheduled for a pulse generator revision and replacement under monitored anesthesia care. Preoperative workflow includes device interrogation and imaging to confirm lead integrity and pocket location, informed consent addressing risks of infection, hematoma, lead migration, and need for lead revision or explantation. Intraoperative steps include surgical exposure of the generator pocket, disconnecting the lead extension, removal of the existing pulse generator or receiver, inspection of the leads and connector integrity, and implantation of the revised or new generator with connector attachment and pocket closure. Postoperative workflow includes device programming, wound care instructions, pain control, and device interrogation before discharge. Typical site of service is an ambulatory surgical center or hospital outpatient operating room for cases requiring surgical pocket creation or revision.
