Unofficial Uncorrected Transcript, posted in the cloud HERE.
For background on the special workshop, see here.
Indirectly related to the above webinar, on September 22, CMS posted its preliminary gapfill/crosswalk recommendations for new codes that will be active in CY2018...here. CMS also released PAMA pricing data for the thousand-plus codes for which PAMA data is available; it's the generally rare or even obsolete codes that didn't have PAMA data that are in the webinar and workshop above.
My personal running notes, typed during the meeting, uncorrected, are provided in the cloud, here.
