Data Release Applications

The Maryland Health Care Commission (MHCC) collects privately insured data (claims and membership), known as the Medical Care Data Base (MCDB), on a quarterly basis from life and health insurance carriers, health maintenance organizations (HMOs), third-party administrators (TPAs), and pharmacy benefits managers (PBMs), who are licensed to do business in Maryland. The MCDB also includes Medicaid and Medicare. The MCDB is Maryland’s All Payer Claims Database; MCDB maintenance is governed by COMAR 10.25.06 and the MCDB data release is governed by COMAR 10.25.05.
