The new CMS code is G0477. It was activated on 1-1-16 and covers "read by direct optical observation" tests, such as dip strip drug tests or cups. You can submit one per date of service (I actually had a Dr. submitting 12 a day for a 12 panel UDS under the old code, and UHC was paying).
The CLIA waiver modifier, QW, is required, BUT there is a problem in the CMS system because they didn't link the QW modifier to the G0477 code, so if you submit G0477-QW it gets denied as "modifier not valid for date of service". My clearinghouse and AAPC recommend submitting G0477 without the QW modifier until after April 1st.
