Which agency is responsible for the administration simplification standards set by HIPAA?

The Center for Medicare and Medicaid Services (CMS) is the agency responsible for the administration simplification standards set by the Health Insurance Portability and Accountability Act (HIPAA). CMS oversees various health care programs and is tasked with implementing and enforcing HIPAA regulations related to the electronic transmission of health information, including standards for electronic transactions and code sets.

This agency plays a critical role in ensuring that health care providers, payers, and other entities comply with HIPAA provisions, thereby promoting secure and efficient handling of medical data. By overseeing these standards, CMS helps to streamline processes and protect patient information, which is a fundamental goal of HIPAA legislation.

The other options, while important agencies in their respective areas, do not have a role in the administration simplifications standards under HIPAA.
