I need help, please. I cannot figure out how to get UHC to reimburse for 98943 when performed on the same day as 98941. I have billed with modifier 59 and it has been denied. I have read all UHC policies and reimbursement procedures and cannot get an answer. So to restate. I am billing 98941 for a 3 level spinal manipulation and 98943-59 for an extremity adjustment linked to a separate diagnosis and UHC denies as using the incorrect modifier.
