Question: One of our clients is starting to use ultrasound guidance for postoperative pain control nerve blocks. Does CPT include a code for this service? Do we report it separately? Idaho Subscriber Answer: CPT does not include an ultrasound guidance code that appropriately fits needle guidance for a nerve block (there are codes for biopsy, abscess drainage and other situations, but not for guidance). If you choose to report both services, your best option for the ultrasound might be 76999 (Unlisted ultrasound procedure [e.g., diagnostic, interventional]). Remember to include any supporting documentation for the procedure if you report the unlisted code. -- You Be the Coder and Reader Questions were answered by Cindy Smith, CPC, anesthesia coder with Professional Healthcare Billing Services in Charleston, W.V.
