I have 2 questions I would like some clarity on based on correct billing guidelines for Chemotherapy drugs:

1. Is there a payable HCPCS chemotherapy drug list anywhere? I have searched high and low. I am trying to find out the payable drugs codes for administration code 96416
2. When billing an add-on code admin code (96411 and 96417), is it required to bill a separate distinct drug code from the primary admin code in order for it to pay.

Any guidance would be appreciated.
