Final answer:
The ARRA, with its HITECH Act component, established the Office of National Coordinator for Health Information Technology to enhance health information technology infrastructure.
Step-by-step explanation:
The legislation that authorized the creation of the Office of National Coordinator for Health Information Technology is the Health Information Technology for Economic and Clinical Health (HITECH) Act, which is part of the American Recovery and Reinvestment Act of 2009 (ARRA). The HITECH Act substantially increased the promotion and expansion of the health information technology infrastructure in the United States. While PPACA deals with the broader aspects of healthcare reform aimed at bringing the U.S. closer to universal coverage, HIPAA sets privacy standards for health information, and TEFRA is related to federal expenditure for healthcare, it was ARRA that specifically addressed the creation and funding for the Office of National Coordinator for Health Information Technology.
