CPT® Code 0106T

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

Quantitative sensory testing (QST) is a diagnostic procedure that evaluates the sensory response of a patient's extremities by applying specific sensory stimuli. This testing is particularly focused on assessing large diameter sensation, which is crucial for understanding the functionality of sensory pathways in the nervous system. During the procedure, a specialized device is utilized to deliver controlled touch pressure stimuli to the patient's limb, allowing the physician to gauge the sensory response accurately. The results of this testing can provide valuable insights into the patient's sensory nerve function and help in diagnosing various neurological conditions. It is important to note that different codes are designated for testing various types of sensory stimuli: for pressure stimulation, the code 0106T is used; for vibration sensation, 0107T; for cool temperature response, 0108T; for heat and/or pain stimuli, 0109T; and for any other stimuli not covered by these codes, 0110T is applicable. This structured approach to sensory testing allows for a comprehensive assessment of the patient's sensory capabilities and aids in the formulation of an appropriate treatment plan.
