Every four months, AMA CPT creates a new webpage for its next upcoming CPT editorial meeting. This is where you find meeting agendas, registration links, etc.
The webpage for the AMA CPT September 2022 meeting in Seattle has been created. Registration will open in early July.
The opportunity for comment on lab applications for this cycle opens first, around July 1. The opportunity to comment on other applications for this cycle should open around July 15.

Cat III
On a separately note, I think that the Category III codes which will be effective in January 2023 will be posted around July 1, here. It looks like new Cat III codes from the Feb 2022 and May 2022 meetings will release on July 2022, effective January 2023, but not published in the CPT book til 2024. Multi-year Cat III calendar here.
PLA
On another calendar, the quarterly new PLA codes appear July 1, October 1, etc, at the bottom of this page here.
