Which entity oversees the credentialing of physicians in Texas?

The correct entity that oversees the credentialing of physicians in Texas is the Texas Medical Board. This state agency is responsible for regulating the practice of medicine in Texas, which includes the licensure of physicians, enforcing the Medical Practice Act, and ensuring that healthcare providers meet professional standards. The Texas Medical Board's functions include evaluating applicants' qualifications, supervising medical practice, and taking disciplinary action when necessary to protect the public.

The roles of other options, while important in the healthcare landscape, do not include the specific authority to credential physicians. The Texas Medical Association primarily serves as a professional organization advocating for physicians and the medical community rather than overseeing physician licensure. The Department of Health Services deals with broader public health matters and does not directly handle physician credentialing. The Texas Board of Nursing oversees the licensure of nurses, focusing on a different segment of the healthcare workforce.
