Summary & Overview
CPT 63655: Spinal Cord Stimulation with Laminectomy and Paddle Electrode
CPT code 63655 describes a surgical spinal cord stimulation implantation that includes removal of part of the vertebral lamina and placement of a permanent plate or paddle electrode in the epidural space. This implant-based neuromodulation procedure is used to provide broader dorsal column coverage or to stabilize the electrode array and is an important option for managing refractory chronic pain and spasticity. Nationally, the code captures a specialized neurosurgical service with implications for facility resource use, device supply, and postoperative care pathways.
Key payers in the national landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and typical settings of service, plus benchmarking and policy-focused content covering reimbursement considerations, utilization patterns, coding guidance, and payer authorization trends where available. The publication also summarizes common modifiers and coding permutations linked to procedural complexity and bilateral or staged approaches. Clinical context covers indications, surgical setting, and expected postoperative considerations to inform coding, billing, and administrative workflows for facilities and specialty practices.
Billing Code Overview
CPT code 63655 describes a surgical procedure in which a portion of the vertebral lamina is removed and a permanent plate/paddle electrode is placed in the epidural space for spinal cord stimulation. The procedure is performed when a larger area of spinal cord coverage is required or to reduce the risk of electrode array migration. It is intended to control chronic pain and reduce spasticity.

Service type: Surgical implant procedure for spinal cord stimulation
-
Typical site of service: Inpatient or outpatient hospital operating room or ambulatory surgical center where neurosurgical or spine procedures are performed
Clinical & Coding Specifications
Clinical Context
A typical patient is a 45–70-year-old adult with chronic, intractable axial and/or radicular neuropathic pain refractory to conservative treatments (physical therapy, medications including opioids, nerve blocks, and radiofrequency ablation). The patient has undergone multidisciplinary evaluation including pain medicine and neurosurgery or orthopedic spine consultation and has had a successful trial of spinal cord stimulation with a percutaneous or temporary paddle lead demonstrating ≥50% pain relief and functional improvement.
The clinical workflow begins with preoperative evaluation: history and physical, assessment of comorbidities, medication reconciliation (anticoagulation management), informed consent, and imaging review (MRI or CT) to determine the appropriate vertebral level for paddle electrode placement. On the day of service, the patient is brought to an operating room or procedure suite under monitored anesthesia care or general anesthesia. A lumbar laminectomy or laminotomy is performed at one or more vertebral levels to create an epidural window. A permanent plate/paddle epidural electrode array is positioned in the posterior epidural space and secured to minimize migration; leads are tunneled and connected to an implanted pulse generator during the same operative session or staged for later implantation. Intraoperative testing verifies stimulation coverage. Postoperative care includes neurologic checks, wound care, pain control, and device programming in clinic. Typical sites of service are an ambulatory surgery center or hospital operating room depending on patient comorbidity and anesthesia needs.
