The CPT® Code 95977 refers to the electronic analysis of an implanted neurostimulator pulse generator or transmitter, which is a device used to deliver electrical impulses to cranial nerves for therapeutic purposes. This procedure involves a comprehensive assessment of various parameters associated with the neurostimulator, including contact groups, interleaving, amplitude, pulse width, frequency (measured in Hertz), on/off cycling, burst mode, magnet mode, dose lockout, and patient-selectable parameters. Additionally, it encompasses the evaluation of responsive neurostimulation, detection algorithms, closed-loop parameters, and passive parameters. The analysis is conducted by a physician or another qualified healthcare professional to ensure the device is functioning optimally. The implanted neurostimulator system consists of a pulse generator that is surgically placed in a subcutaneous pocket, with leads that are tunneled from the nerve being stimulated to the generator. This setup allows for the delivery of electrical impulses to treat various conditions, such as chronic pain, epilepsy, and depression. Regular electronic analysis is crucial for monitoring the device's performance and making necessary adjustments to maintain its efficacy. During this analysis, the healthcare professional documents any logged events from the neurostimulator, assesses battery status, measures electrode impedance, and reviews the current programmed settings. For cranial nerve neurostimulator pulse generator programming, the healthcare provider adjusts specific parameters to achieve optimal therapeutic stimulation. This may involve modifying the frequency, pulse width, current, duration, magnetic mode, or sensing capabilities of the device. The programming process may include multiple trials where three or fewer parameters are adjusted for a simple cranial nerve neurostimulator pulse generator (CPT® Code 95976) and four or more parameters for a complex one (CPT® Code 95977), until the desired therapeutic effect is achieved.

The electronic analysis and programming of an implanted neurostimulator pulse generator/transmitter, as described by CPT® Code 95977, is indicated for patients who require ongoing management of cranial nerve stimulation for various medical conditions. The specific indications include:
The procedure for electronic analysis and programming of the cranial nerve neurostimulator pulse generator/transmitter involves several detailed steps:
After the electronic analysis and programming of the neurostimulator pulse generator/transmitter, the patient may be monitored for any immediate reactions to the adjustments made. It is essential to provide the patient with information regarding potential side effects and the importance of reporting any changes in their symptoms or device performance. Follow-up appointments may be scheduled to reassess the device's effectiveness and make further adjustments as necessary. The healthcare provider will also review the patient's overall treatment plan to ensure that the neurostimulation continues to meet their therapeutic needs.

| GZ | Item or service expected to be denied as not reasonable and necessary | 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. | 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.) | GC | This service has been performed in part by a resident under the direction of a teaching physician | GA | Waiver of liability statement issued as required by payer policy, individual case | 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). | 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. | 24 | Unrelated evaluation and management service by the same physician or other qualified health care professional during a postoperative period: the physician or other qualified health care professional may need to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) unrelated to the original procedure. this circumstance may be reported by adding modifier 24 to the appropriate level of 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. | 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). | 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. | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | 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. | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | CR | Catastrophe/disaster related | FS | Split (or shared) evaluation and management visit | GW | Service not related to the hospice patient's terminal condition | GY | Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit | LT | Left side (used to identify procedures performed on the left side of the body) | PD | Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days | Q0 | Investigational clinical service provided in a clinical research study that is in an approved clinical research study | SA | Nurse practitioner rendering service in collaboration with a physician | X4 | Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
