Official Description

H-reflex, amplitude and latency study; record muscle other than gastrocnemius/soleus muscle

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 95936 refers to an H-reflex amplitude and latency study that specifically records the activity of muscles other than the gastrocnemius and soleus muscles, which are located in the lower leg. The H-reflex is a diagnostic test that evaluates the function of the spinal cord and peripheral nerves by measuring the electrical response of muscles to stimulation of sensory nerves. This procedure is particularly useful in assessing neuromuscular conditions and can provide valuable information regarding nerve conduction and muscle response. By focusing on muscles other than the commonly tested gastrocnemius and soleus, this code allows for a broader evaluation of lower leg muscle function, which may be necessary in certain clinical scenarios. The results of this study can help healthcare professionals diagnose and manage various neuromuscular disorders effectively.

1. Indications

The H-reflex amplitude and latency study using CPT® Code 95936 is indicated for the evaluation of various neuromuscular conditions. This procedure may be performed in the following situations:

  • Assessment of Neuropathy to determine the integrity of peripheral nerves and their function.
  • Evaluation of Radiculopathy to assess nerve root involvement and its impact on muscle function.
  • Investigation of Muscle Disorders to analyze the response of muscles other than the gastrocnemius and soleus, which may be affected in certain conditions.
  • Monitoring of Disease Progression in patients with known neuromuscular disorders to evaluate changes in muscle response over time.

2. Procedure

The procedure for conducting an H-reflex amplitude and latency study as described by CPT® Code 95936 involves several key steps:

  • Preparation of the Patient includes explaining the procedure to the patient, obtaining informed consent, and positioning the patient comfortably to ensure accurate results. The skin over the muscles to be tested is cleaned to reduce impedance and improve electrode contact.
  • Electrode Placement involves placing surface electrodes on the skin over the target muscles, which are not the gastrocnemius or soleus. The electrodes are positioned to capture the electrical activity of the muscles during stimulation.
  • Nerve Stimulation is performed by delivering a mild electrical stimulus to the appropriate sensory nerve, which elicits the H-reflex response in the targeted muscles. The intensity and duration of the stimulus are carefully controlled to ensure patient comfort and safety.
  • Recording of Responses entails measuring the amplitude and latency of the H-reflex response. The data collected is analyzed to assess the function of the peripheral nerves and the muscles involved.
  • Data Interpretation involves reviewing the recorded responses to determine any abnormalities in nerve conduction or muscle response, which can aid in diagnosing underlying neuromuscular conditions.

3. Post-Procedure

After the H-reflex amplitude and latency study is completed, the patient may be monitored briefly to ensure there are no immediate adverse effects from the procedure. Typically, there are no significant post-procedure restrictions, and patients can resume normal activities unless otherwise advised by the healthcare provider. The results of the study will be documented and analyzed, and a report will be generated to assist in the diagnosis and management of the patient's condition. Follow-up appointments may be scheduled to discuss the findings and any necessary treatment plans.
