Claims - The All Payer Claims Database (APCD)

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.

See Rule Chapter 243 on our rules page for a complete definition of what entities must submit data and what data must be submitted.

MHDO makes available new and updated data quarterly. Historical data is available upon request.
