AMA CPT has published new PLA code submissions for public comment. The codes will be discussed at a teleconference around August 8 and stakeholders can review the list and request information on a code that they want to comment on. They now go through ZENDESK portals, which I think is how CPT Cat I codes have been handled too.
See instructions for how to comment on the PDF.
