Official Description

Posterior tibial neurostimulation, percutaneous needle electrode, single treatment, includes programming

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Posterior tibial neurostimulation is a therapeutic procedure aimed at managing conditions such as overactive bladder, urge incontinence, and frequent urination in patients who have not responded to other treatment options. This procedure targets the posterior tibial nerve, which is a branch of the sacral nerve plexus, a network of nerves that play a crucial role in bladder and pelvic floor function. By utilizing neuromodulation techniques, the procedure involves sending mild electrical impulses to stimulate the sacral nerve plexus, which can enhance the control and function of voiding. During the procedure, the patient's foot is positioned comfortably, and the area above the ankle, where the tibial nerve is located, is thoroughly cleansed to ensure a sterile environment. A fine-needle electrode is then carefully inserted near the nerve, allowing for the delivery of low-voltage electrical stimulation. This stimulation is administered at a prescribed voltage for a specific duration, tailored to the patient's needs. The CPT® Code 64566 specifically reports a single treatment session of this procedure, with most patients typically undergoing weekly sessions over a course of 10 to 12 weeks to achieve optimal results.

1. Indications

Posterior tibial neurostimulation is indicated for the treatment of the following conditions:

  • Overactive Bladder A condition characterized by an urgent need to urinate frequently, often leading to incontinence.
  • Urge Incontinence The involuntary loss of urine associated with a strong, sudden urge to urinate.
  • Frequent Urination A symptom where patients experience the need to urinate more often than normal, which can disrupt daily activities and quality of life.

2. Procedure

The procedure for posterior tibial neurostimulation involves several key steps that ensure effective treatment.

  • Step 1: Patient Preparation The patient is positioned comfortably, with their foot elevated and supported to facilitate access to the ankle area. This positioning helps to relax the muscles and allows for better access to the posterior tibial nerve.
  • Step 2: Skin Cleansing The skin over the tibial nerve, located just above the ankle, is thoroughly cleansed to maintain a sterile environment and reduce the risk of infection during the procedure.
  • Step 3: Neurostimulator Programming A neurostimulator device is programmed according to the specific treatment plan for the patient. This programming is crucial as it determines the parameters of the electrical stimulation that will be delivered.
  • Step 4: Electrode Insertion A fine-needle electrode is carefully inserted adjacent to the posterior tibial nerve. This step requires precision to ensure that the electrode is positioned correctly for effective stimulation.
  • Step 5: Electrical Stimulation Once the electrode is in place, low-voltage electrical stimulation is delivered to the nerve. The stimulation is administered at a prescribed voltage for a specific duration, tailored to the individual patient's treatment needs.

3. Post-Procedure

After the procedure, patients may experience mild discomfort at the insertion site, which typically resolves quickly. It is important for patients to follow any post-procedure care instructions provided by their healthcare provider. Most patients will undergo a series of treatments, usually once a week, over a period of 10 to 12 weeks to achieve the desired therapeutic outcomes. Regular follow-up appointments may be scheduled to monitor progress and adjust treatment as necessary.

LT Left side (used to identify procedures performed on the left side of the body)
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.
GZ Item or service expected to be denied as not reasonable and necessary
CR Catastrophe/disaster related
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. (for repeat procedures on the same day, see modifier 76.)
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).

GC This service has been performed in part by a resident under the direction of a teaching physician
AG Primary physician
GW Service not related to the hospice patient's terminal condition
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.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient 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).
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).
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.)
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
