What was established to integrate the administration of Medicare Parts A and B fee-for-service benefits?

The correct answer to the question regarding the establishment for integrating the administration of Medicare Parts A and B fee-for-service benefits is MCR (Medicare Common Coordinated System). This system was designed to streamline and enhance the efficiency of billing and claims processing for Medicare beneficiaries enrolled in parts A and B, allowing for a more cohesive and user-friendly experience both for healthcare providers and beneficiaries.

MCR aimed to reduce administrative burdens and improve coordination of care by establishing standardized processes that integrate the two separate components of Medicare. The goal was to facilitate better communication, ensure accurate billing, and deliver comprehensive support services, thereby improving the overall management of these benefits.

The other terms listed, such as TEFRA (Tax Equity and Fiscal Responsibility Act), HIPAA (Health Insurance Portability and Accountability Act), and OBRA (Omnibus Budget Reconciliation Act), while significant in healthcare and insurance contexts, do not specifically correspond to the integration of Medicare Parts A and B benefits. TEFRA primarily dealt with Medicare reimbursement policies, HIPAA focused on privacy and security regulations in healthcare, and OBRA included a series of laws concerning Medicare and Medicaid but didn't specifically address the integration of Parts A and B.
