I need help. We have been doing hemoglobin tests in the office - with afinger prick - This is new for us and NGS is denying when we bill. We are billing a e/m visit w/ 25 modifier and 36416, and 85018 w/ QW modifier and w've added our CLIA# and on line 19 of claim are typing in the hemoglobin result. I cannot get CMS to process the 36416, nor the 85018 QW. Any advice out there? Thanks in advance
