Extracts and Releases
This page was updated on: 9/15/2022
This page provides the status of data file extract requests and CHIA’s APCD and Case Mix annual releases. CHIA updates this page when there are significant changes to either the releases or the request queue. You may also sign up 
to receive email updates for information on both data requests and annual releases.
Please note that it can take from five to seven days to create each extract file and that some customer requests require multiple extracts. Priority is given to state agencies followed by data submitters and then to independent researchers.
Please Note: For additional information regarding the MA APCD, please see the MA APCD documentation archive and the MA APCD data submission guides.
