CPT® Code 0107T

Quantitative sensory testing (QST), testing and interpretation per extremity; using vibration stimuli to assess large diameter fiber sensation

Quantitative sensory testing (QST) is a diagnostic procedure that evaluates the sensory response of a patient's extremities, specifically focusing on large diameter fiber sensation. This testing involves the use of a specialized device that delivers controlled sensory stimuli, such as vibration, to assess how well the nerves in the limb respond to these stimuli. The primary aim of QST is to identify any abnormalities in sensory perception, which can be indicative of various neurological conditions. The procedure is particularly useful in diagnosing conditions that affect nerve function, such as diabetic neuropathy or other peripheral nerve disorders. It is important to note that different codes are designated for testing various types of sensory stimuli; for instance, pressure stimulation is coded under 0106T, while cool temperature sensation is tested under 0108T, and heat or pain stimuli are covered by 0109T. This structured approach allows for precise documentation and coding of the specific sensory tests performed, ensuring accurate representation of the patient's sensory evaluation.
