We are having issues while trying to bill the new 2020 codes for vascular mapping. We've been billing 93986 (unilateral) or 93985 (bilateral). There is no issue here. -- The code book tells you that you can code 75820 (unilateral) or 75822 (bilateral) along with code 36005. There is no bundling issue in our software, but the claims keep getting rejected, because it states that 36005 bundles into 75820 and 75822. We've even tried to append modifier -59 (as well as the laterality modifiers) to code 36005, but nothing seems to be working. Can you provide guidance on how to bill successfully, as a physician, for vascular mapping?
