Since passage of the state budget in 2013, the State of Connecticut has been collecting health data under a program called the All Payer Claims Database (APCD), a massive compendium of medical claims and costs meant to allow consumers, hospitals, insurers, researchers, lawmakers, and state agencies to access that data, gain insights into Connecticut’s healthcare landscape, and help lower the cost of healthcare in the state.
