Maine has collected health insurance claims information in its APCD since 2003. The APCD currently holds claims from commercial insurance carriers, third party administrators (TPAs), pharmacy benefit managers (PBMs), dental benefit administrators, MaineCare(Maine Medicaid), and CMS (Medicare).
Health care claims processors must submit periodically (typically monthly) to the MHDO, a completed health care claims data set for all members who are Maine residents. The submissions include files with member eligibility, medical claims, pharmacy claims, and/or dental claims information. Please see Rule Chapter 243 on our Rules and Statutes page for a complete definition of entities that must submit data and of the data that must be submitted.
Elements available in the various data sets can be found in the APCD Data Dictionary!
In addition you may review the specific set of validations the claims data are measured against before the MHDO accepts into our database.
If you are interested in requesting data, our Request Data or Reports page has all the information you need.
Note: Release dates of claims data can be found on our Data Release Schedules page.
