Official Description

Motor and/or sensory nerve conduction, using preconfigured electrode array(s), amplitude and latency/velocity study, each limb, includes F-wave study when performed, with interpretation and report

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 95905 refers to a specific type of nerve conduction study that assesses both motor and sensory nerve function using preconfigured electrode arrays. This procedure is essential for diagnosing and evaluating various nerve disorders, including conditions such as carpal tunnel syndrome, which is characterized by symptoms like numbness, tingling, and other abnormal sensations in the limbs. The use of automated systems in these studies allows for efficient testing of sensory and motor nerves, particularly in the wrist and foot regions, where the median, ulnar, peroneal, posterior tibial, and sural nerves are commonly evaluated. During the procedure, a preconfigured electrode array is affixed to the skin of the limb being tested, enabling the delivery of electrical pulses. The study measures the conduction time, which is the duration it takes for the muscle to contract in response to the electrical stimulus. Additionally, the amplitude, or strength of the nerve response, along with the speed of conduction, indicated by latency or velocity, is meticulously recorded. An F-wave study may also be included, which involves the assessment of small amplitude, long latency responses that occur when the motor nerve is maximally stimulated. This aspect of the study provides valuable insights into the functionality of the proximal segments of the nerve. Typically, multiple F-wave recordings are captured at each stimulus site, and the data can be processed on-site or transmitted to a remote computer for analysis. Ultimately, the physician interprets the results and compiles a comprehensive written report detailing the findings of the nerve conduction study.

1. Indications

The procedure associated with CPT® Code 95905 is indicated for the evaluation of various nerve-related conditions and symptoms. The following are the explicitly provided indications for performing this nerve conduction study:

  • Diagnosis of Nerve Damage This procedure is utilized to diagnose and assess damage to peripheral nerves, which may be caused by trauma, compression, or other pathological conditions.
  • Nerve Disorders It is performed to evaluate specific nerve disorders, including but not limited to carpal tunnel syndrome, which affects the median nerve in the wrist.
  • Symptoms of Nerve Dysfunction The study is indicated for patients presenting with symptoms such as numbness, tingling, or other abnormal sensations in the limbs, which may suggest underlying nerve issues.

2. Procedure

The procedure for CPT® Code 95905 involves several key steps that ensure accurate assessment of nerve function. The following outlines the procedural steps:

  • Step 1: Preparation The patient is positioned comfortably, and the limb to be tested is exposed. The skin is cleaned to ensure good electrode contact, and the preconfigured electrode array is prepared for application.
  • Step 2: Electrode Placement The preconfigured electrode array is affixed to the skin of the limb being tested. This array is designed to facilitate the delivery of electrical pulses to the nerves under examination.
  • Step 3: Electrical Stimulation Electrical pulses are sent through the electrode array to stimulate the sensory and/or motor nerves. The response of the nerves is recorded, capturing both the amplitude and the conduction time.
  • Step 4: F-Wave Study (if performed) If indicated, an F-wave study is conducted by applying maximal stimulation to the motor nerve while directing the electrode away from the muscle being recorded. This step involves capturing multiple F-wave recordings to assess the proximal nerve function.
  • Step 5: Data Recording The conduction time, amplitude, latency, and velocity of the nerve responses are meticulously recorded. These recordings may be processed on-site or transmitted to a remote computer for further analysis.
  • Step 6: Interpretation and Reporting After the recordings are completed, the physician reviews the data and interprets the findings. A comprehensive written report is generated, detailing the results of the nerve conduction study.

3. Post-Procedure

Post-procedure care for patients undergoing the nerve conduction study with CPT® Code 95905 typically involves minimal recovery time, as the procedure is non-invasive. Patients may resume normal activities immediately following the test. However, they may be advised to avoid strenuous activities for a short period, depending on the physician's recommendations. The physician will discuss the findings from the nerve conduction study with the patient during a follow-up appointment, where further management or treatment options may be considered based on the results.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
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.
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.
