I bill for a pain management office who routinely perform in office (cups) drug screening for patients on RX narcotic meds. We would normally bill G0434-QW for such tests, but now I'm getting rejections for this. I know CMS did away with this code and replaced with several others. I started billing G0477-QW in 2016 and am still getting rejections and denials. Can physicians still be reimbursed for in office drug screens in 2016, and if so, what is the appropriate code for the test? Any guidance would help! Thanks.
