Official Description

Revision or removal of peripheral, sacral, or gastric neurostimulator pulse generator or receiver, with detachable connection to electrode array

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 64595 refers to the procedure involving the revision or removal of a peripheral, sacral, or gastric neurostimulator pulse generator or receiver that has a detachable connection to an electrode array. This procedure is essential for managing patients who have undergone neurostimulation therapy for various conditions, such as chronic pain, bladder or bowel dysfunction, or gastroparesis. The neurostimulator pulse generator is an implantable device that generates electrical impulses, which are delivered to specific electrodes implanted in the body. These impulses are designed to stimulate nerves in targeted areas, thereby alleviating symptoms associated with the patient's condition. In the context of gastric neurostimulation, the device delivers mild electrical impulses to the antrum of the stomach, which can help improve gastric motility in patients suffering from gastroparesis. For sacral neurostimulation, the device targets nerves that control bladder and bowel functions, aiming to restore normal physiological activity. Peripheral nerve stimulation, on the other hand, focuses on delivering impulses to specific areas to manage chronic pain effectively. The procedure described by CPT® Code 64595 encompasses both the revision and complete removal of the neurostimulator device. During revision, the existing device is evaluated, and necessary adjustments are made to ensure its proper functioning. This may involve detaching the device from the electrodes and removing it entirely if required. The procedure is performed through an incision in the skin, allowing access to the subcutaneous pocket where the device is located. The careful handling of the device and electrodes is crucial to maintain the integrity of the surrounding tissue and ensure optimal outcomes for the patient.

1. Indications

The procedure described by CPT® Code 64595 is indicated for patients who require revision or removal of an existing peripheral, sacral, or gastric neurostimulator pulse generator or receiver. The specific indications for this procedure may include:

  • Device Malfunction: The existing neurostimulator may not be functioning correctly, necessitating revision or removal.
  • Infection: There may be an infection at the site of the device that requires removal to prevent further complications.
  • Patient Discomfort: Patients may experience discomfort or adverse effects from the device, prompting the need for revision or removal.
  • Device Upgrade: The procedure may be performed to replace an older model with a newer version that offers improved functionality.
  • Change in Treatment Plan: A change in the patient's treatment plan may require the removal of the neurostimulator.

2. Procedure

The procedure for CPT® Code 64595 involves several detailed steps to ensure the safe and effective revision or removal of the neurostimulator pulse generator or receiver. The steps are as follows:

  • Step 1: The procedure begins with the patient being positioned appropriately, and local anesthesia is administered to minimize discomfort during the operation. The surgical site is then prepared and draped in a sterile manner.
  • Step 2: An incision is made in the skin over the existing neurostimulator device, allowing access to the subcutaneous pocket where the device is located. Care is taken to minimize trauma to surrounding tissues.
  • Step 3: The existing generator or receiver is carefully dissected free from the surrounding tissue. This involves gently separating the device from any adhesions or connections to ensure it can be removed without damaging the electrodes or surrounding structures.
  • Step 4: Once the device is free, it is evaluated for functionality. If the device is to be revised, adjustments are made as necessary to ensure it operates correctly. If complete removal is indicated, the device is detached from the electrodes, which may be left in place or also removed, depending on the clinical situation.
  • Step 5: After the device has been revised or removed, the surgical site is inspected for any signs of infection or complications. The pocket is then closed with sutures, ensuring that the incision is properly sealed to promote healing.

3. Post-Procedure

Post-procedure care following the revision or removal of a neurostimulator pulse generator or receiver involves monitoring the patient for any immediate complications, such as infection or excessive bleeding. Patients are typically advised to keep the surgical site clean and dry, and to follow specific instructions regarding activity restrictions to promote healing. Follow-up appointments may be scheduled to assess the surgical site and the patient's recovery progress. If a new device is being implanted, additional instructions regarding the care and management of the new neurostimulator will be provided. Patients should also be informed about potential signs of complications that warrant immediate 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.
SG Ambulatory surgical center (asc) facility service
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79.
