I'm billing for an ASC , can I bill cpt 20926 (obtain tissue graft) with 76942 (ultrasonic guidance) using the TC modifier. We also bill 29893 (Endoscopic plantar fasciotomy) with 76000 (fluoroscopy) using the TC. We do own the equipment and the surgeon is billing for the professional part of 76942 & 76000. I do not believe that PA Medicare has a fee for either radiology code for the ASC but this should be reimburse by other payer. Any Feedback to billing this would be great.
