I have a question regarding billing for a UA (attached to a office visit). I have two codes F12.20 (cannabis dependence, uncomplicated) and Z79.891 (long term current opioid use). I believe the general rule is if there is a dependence code and a use code to throw out the use code and just bill using dependence (ex: f11.20(opioid dependence, uncomplicated and z79.891(long term current opioid use) we just use f11.20), but since these are two different drugs can we bill using both, or should the use still be thrown out? Thank you! Jenn
