The enforcement of the Health Insurance Portability and Accountability Act (HIPAA) regulations is primarily the responsibility of the Office for Civil Rights (OCR) within the U.S. Department of Health and Human Services (HHS). The OCR is tasked with enforcing the privacy and security rules established under HIPAA, ensuring that healthcare providers, health plans, and other covered entities comply with the regulations aimed at protecting individuals' health information.
