MA APCD and Case Mix User Workgroup Information

MA APCD and Case Mix
Webinar Workgroup Information



These webinar workgroups bring together external users of CHIA’s MA APCD and Case Mix data with CHIA’s in-house data experts to discuss analytical techniques, data issues, and data quality.  The webinars are also used for announcements regarding data releases, enhancements, and features.

Of note, each meeting features a segment where CHIA staff answer common questions from data users and field live questions from webinar participants. CHIA invites you to join the All-Payer Claims Database (MA APCD) and Case Mix mailing list to receive occasional email notifications regarding these workgroup meetings.

Please register for one or both of these workgroups at the separate registration links on this page.

Meetings take place on the 4th Tuesday of every month at 3:00p.m., with APCD and Case Mix workgroups alternating every month.  See the upcoming schedule below.
