Wiki 2020 changes question

[amowens854]

Hey everyone,
I have a question about the new CPT 2020 changes. Do we start using them January 1 no matter the DOS? or do we go off the DOS?
I looked on AMA website and didn't find anything...
TIA

by the DOS.

Thank you. I started to doubt myself and wanted to double check.
