Ask Dr. Z

Dr. Z, Really need your thoughts on the appropriate codes for a dicyphor discogram. We have an IR doc performing these. His documentation has changed a little since he began and not sure if this makes a difference or not. Now he documents " Dicphor needle advanced into the disk space. Dicyphor balloon positioned in the center of the disc space. Slight amount of contrast and 0.5 milliliters of lidocaine and 1.5 milliliters of bupivacaine were instilled into the disk space.....do I use the appropriate Diskogram codes or do I use an unlisted code? Thanks for you help.
