Official Description

Percutaneous implantation of neurostimulator electrode array, epidural

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 63650 refers to the procedure of percutaneous implantation of a neurostimulator electrode array in the epidural space. This procedure is primarily performed to manage chronic back and/or leg pain through the use of spinal cord stimulation. The underlying principle of this technique involves the application of electrical stimulation to the spinal cord, which activates pain-inhibiting neurons. This activation results in a tingling sensation that effectively masks the perception of pain, providing relief to patients suffering from persistent discomfort. During the procedure, a small incision is made at the designated insertion site, and fluoroscopic guidance is utilized to ensure accurate placement of the electrode array. The procedure involves exposing the vertebra and performing a laminotomy, which entails the removal of a small portion of the lamina to access the epidural space. The electrode array, commonly referred to as leads, is then carefully advanced into this space and secured in place with sutures. Following the placement, the patient is awakened to test the electrode array, ensuring proper positioning and confirming that the implantation does not induce additional pain. The neurostimulator is calibrated at various settings to determine the most effective configuration for pain management, which will later be used to program the pulse generator or receiver in a subsequent procedure. The lead wires are then tunneled to the pocket designated for the pulse generator/receiver, where they are connected to complete the system setup.

1. Indications

The procedure described by CPT® Code 63650 is indicated for patients experiencing chronic back and/or leg pain. This condition may arise from various underlying issues, including but not limited to degenerative disc disease, failed back surgery syndrome, or other neuropathic pain syndromes. The goal of the procedure is to alleviate pain through the implantation of a spinal cord stimulation system, which provides electrical stimulation to the spinal cord to inhibit pain signals.

  • Chronic Back Pain Persistent pain in the back that lasts for an extended period, often requiring intervention for relief.
  • Chronic Leg Pain Ongoing pain in the legs that may be associated with nerve damage or other underlying conditions.

2. Procedure

The procedure for CPT® Code 63650 involves several critical steps to ensure the successful implantation of the neurostimulator electrode array.

  • Step 1: Preparation and Anesthesia The patient is positioned appropriately, and local anesthesia is administered to minimize discomfort during the procedure. Sedation may also be provided to help the patient relax.
  • Step 2: Incision and Exposure A small incision is made in the skin over the planned insertion site. Fluoroscopic guidance is utilized to accurately locate the epidural space. The underlying tissues are carefully dissected to expose the vertebra.
  • Step 3: Laminotomy A small portion of the lamina is removed through a procedure known as laminotomy. This step is crucial as it allows access to the epidural space where the electrode array will be placed.
  • Step 4: Electrode Array Placement The neurostimulator electrode array, or leads, is advanced into the epidural space. The leads are positioned carefully to ensure optimal placement for effective stimulation.
  • Step 5: Securing the Electrode Array Once the electrode array is in the correct position, it is secured in place with sutures to prevent movement and ensure stability.
  • Step 6: Testing the Device The patient is awakened to test the electrode array. This step is essential to confirm that the neurostimulator is properly placed and that the patient does not experience pain from the implant itself.
  • Step 7: Programming the Neurostimulator The neurostimulator is tested at various settings to determine the optimal configuration for pain relief. Once the best settings are identified, they will be used to program the pulse generator or receiver, which will be implanted in a separate procedure.
  • Step 8: Tunneling and Connection The lead wires are tunneled to the pocket designated for the pulse generator/receiver, where they are attached to complete the system setup.

3. Post-Procedure

After the completion of the procedure, the patient is monitored for any immediate complications or adverse reactions. Post-procedure care may include pain management strategies and instructions for activity restrictions to promote healing. Patients are typically advised to avoid strenuous activities and heavy lifting for a specified period. Follow-up appointments are essential to assess the effectiveness of the neurostimulator and make any necessary adjustments to the programming for optimal pain relief. Additionally, patients may receive guidance on how to manage their device and recognize any signs of complications that may require medical attention.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.

77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
