We are trying to get more information on using Z01.818 for office visits for patients prior to chemo treatments as they evaluate the effects of chemo on the patient and whether they can continue with their treatment on that day or not. Of course, if no treatment is given, this code cannot be used. These office visits are usually a level 3 or 4, sometimes a 5. We know that the chemo admin code has a low level inherent E/M included. One of the descriptions we found for Z01.818 is "an encounter for examination prior to antineoplastic chemotherapy".

Does anyone use this code? Are there issues with denials and/or certain payers? What is the criteria you use to use this dx?

Thank you.
