Which credentialing process verifies the quality of a health care provider?

The credentialing process that verifies the quality of a health care provider is the National Committee for Quality Assurance (NCQA). NCQA is a private, non-profit organization focused on improving health care quality through the accreditation of health care organizations, particularly managed care organizations, and health plans. They establish performance measures that assess the quality of care provided and ensure that organizations are meeting high standards of care and service.

NCQA's accreditation processes help consumers, employers, and regulators identify health care providers and organizations that emphasize quality in their services. By evaluating healthcare systems and requiring adherence to established performance benchmarks, NCQA ensures that providers are not only qualified to practice but are also committed to delivering high-quality care.

In contrast, the other options listed have different functions: the NPI (National Provider Identifier) is a unique identification number for covered healthcare providers, DNV GL is an organization offering accreditation and quality management for healthcare organizations but focuses more on overall management systems rather than solely on provider quality, and APM (Alternative Payment Model) refers to a healthcare payment approach rather than a credentialing process. Therefore, NCQA is the most appropriate choice for verifying the quality of health care providers.
