Medical credentialing is the process of verifying and evaluating the qualifications and credentials of healthcare providers, such as physicians, nurses, and other medical professionals, to ensure that they meet the standards required to practice medicine in a particular setting. This includes reviewing their education, training, licensure, work history, and other relevant information. Credentialing is typically done by hospitals, health systems, insurance companies, and best medical credentialing companies to ensure that their providers are qualified to provide safe and effective care to patients.
