I have a question. As an Anesthesia Coder, I do not always have access to any other record than the Anesthesiologists documentation. My question here is, if I only know say the procedure being performed and not if it is therapeutic or diagnostic, how would I know which code to select say for a TFESI, 64483 or a MBB, 64493? In 2017, 64483 would crosswalk to 01935 and 01936 but the crosswalk has changed since 2018. I am not sure as to why it changed. Do you have literature or know where I can find this information out? Both of these are image guided and are percutaneous and seems they would meet the criteria for 01935 or 01936 but 01991 or 01992 is used for diagnostic or therapeutic injection (depending on the position) performed by a different physician or qualified health care professional. I assume “other” means not the physician performing the actual injection. I am looking for more clarity on utilizing these Anesthesia CPT codes.
Thank you in Advance for your help!
