The Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CGCAHPS) survey is a standardized tool to measure patient perceptions of care delivered by a provider (e.g. physician, nurse practitioner, physician assistant, etc.) in an office setting.

The Centers for Medicare & Medicaid Services (CMS) issued the Physician Fee Schedule final rule on Nov. 16, 2012, confirming implementation of CGCAHPS for Physician Quality Reporting System (PQRS) participants as part of the CAHPS for PQRS program. CMS requires CGCAHPS data collection for medical practices with over 100 eligible professionals under one tax identification number who are submitting PQRS through the GPRO web interface and will start mandatory participation for groups with 100 or more eligible professionals in 2015. Both Pioneer ACOs and Medicare Shared Savings Program ACOs are required to participate in annual CGCAHPS data collection as part of the ACO CAHPS program.
