CPT® Code 0108T

Quantitative sensory testing (QST), testing and interpretation per extremity; using cooling stimuli to assess small nerve fiber sensation and hyperalgesia

Quantitative sensory testing (QST) is a diagnostic procedure that evaluates the sensory response of a patient's extremities to various stimuli. Specifically, CPT® Code 0108T refers to the testing and interpretation of sensory responses using cooling stimuli to assess small nerve fiber sensation and hyperalgesia. This procedure is essential for identifying abnormalities in sensory perception, particularly in conditions affecting small nerve fibers, which can be indicative of neuropathies or other sensory disorders. During the test, a specialized device is employed to deliver controlled cooling sensations to the limb being assessed, allowing healthcare professionals to measure the patient's sensory thresholds and responses accurately. The results of this testing can provide valuable insights into the patient's neurological function and help guide further diagnostic and therapeutic decisions. It is important to note that different codes are designated for testing other types of sensory stimuli, such as pressure, vibration, heat, and pain, ensuring that each aspect of sensory function can be thoroughly evaluated and documented.
