All Payer Claims Databases (APCDs)

Dataset Summary

The All-Payer Claims Databases (APCDs) are state-level datasets that collect healthcare claims from multiple payers, including commercial insurers and, in some states, Medicaid and Medicare. APCDs are designed to support transparency, policy evaluation, and population health research at the state level.

These databases typically include medical, pharmacy, and sometimes dental claims across inpatient, outpatient, and professional settings. Because APCDs are administered at the state level, the scope of included payers, care settings, years available, and access procedures vary considerably. Uninsured individuals are generally not captured.
