Health Data and Quality   MCDB  

The Maryland Medical Care Data Base (MCDB) is the Maryland portion of the All Payer Claims Database (APCD). Although the APCD includes enrollment, provider, and claims data for Maryland residents enrolled in private insurance, Medicare fee-for-service and Medicare Advantage, and Medicaid Managed Care Organizations, ONLY the private claims are available for approved data release. The private claims exclude self-insured ERISA health plans beginning in 2015 because of the SCOTUS ruling in Gobeille v. Liberty Mutual Insurance Company. The MCDB supports estimates of cost and utilization, policy analyses, and evaluations of demonstration programs, and is a decision support tool for State partners, such as the Maryland Insurance Administration and the Health Services Cost Review Commission.
