Hello, Our provider performed an arthroscopy of the knee and we billed 29873 and 29875-59. The claim was process and paid. Our provider had an assistant surgeon and the charges were billed and both denied. How can you get a code paid that does support an assistant surgeon (29875) , if you have a CCI edit with the primary CPT code (29873)? CPT code 29873 is not payable to assistant but 29875 is payable. Thank you for your help with this!
