2016 CPT® code

PROCEDURE PERFORMED: Native kidney biopsy. PROCEDURE: After obtaining consent, the patient was taken to ultrasound room. She was put in the prone position. Both kidneys were difficult to visualize. The right kidney was chosen. Skin was prepped in the usual fashion. Lidocaine was used for local anesthesia. Using real-time ultrasound guidance, the right kidney was accessed multiple times. At least six core biopsies were obtained and were sent for light and electromicroscopy in addition to immune fluorescence. Post biopsy ultrasound showed no evidence of hematoma

Please advise on; What is the 2016 CPT® codes? It takes 2 codes; and maybe modifiers as well.

Thank you.
