CMS QRDA IGs

The CMS Quality Reporting Document Architecture (QRDA) Implementation Guides (IGs) are based on the HL7 QRDA IGs. CMS's QRDA Category I IG is used for Hospital Inpatient Quality Reporting (IQR) and Medicare and Medicaid Promoting Interoperability Program for Eligible Hospitals and Critical Access Hospitals (CAHs). CMS's QRDA Category III IG is used for the Eligible Clinicians and Eligible Professionals Programs that address aggregate reporting requirements for Comprehensive Primary Care Plus (CPC+), Merit-Based Incentive Payment System (MIPS) programs, and Medicaid Promoting Interoperability (PI).
