At this point it is possible for us to download the installer for v9.0 to your server and update your software.
As far as I know Disk will still not be available to ship until the 18th of Feb. If you'd like to go ahead and download the installer and schedule your update please give our installation support team a call. You can find the contact information here.
On a side note - You can manually add the CDT 2019 codes to your current version of PracticeWorks, however, until you do update they will be found under the 'other' code list. This would allow you to use the new codes correctly on the claim though.
