0108T Cool quantitative sensory test

Category III

Also known as: QST cold test, cold threshold testing, thermal QST cooling

Quantitative sensory testing (QST) using cooling stimuli to assess cold sensation thresholds and cold pain thresholds. Category III code for standardized psychophysical testing of cold perception.

In Plain Language

cold sensitivity test; cold sensation test

Clinical Context

Used for quantitative sensory testing using calibrated cooling stimuli to assess small fiber (A-delta) sensory function. Cold detection and cold pain thresholds help evaluate small fiber neuropathy, which may not be detected by standard nerve conduction studies.

RVU Information

CPT 0108T does not have a physician work RVU assigned by CMS. Category III codes for emerging technology do not receive RVU assignments. Reimbursement is negotiated with individual payers.

Billing & Documentation

Category III codes are temporary codes for emerging technology, services, and procedures. They are not assigned RVU values by CMS. Coverage and reimbursement vary by payer — check with individual insurers before billing. These codes sunset after 5 years if not converted to Category I.
