What does the MACRA legislation, which took effect on January 1st, 2020, apply to?

The correct answer is that MACRA legislation applies specifically to all carriers offering Medicare supplement plans. The Medicare Access and CHIP Reauthorization Act (MACRA) primarily focuses on reforming the way Medicare pays healthcare providers. It aims to stabilize and improve the quality of care delivered to beneficiaries by shifting payment models and incorporating value-based care measures.

Under MACRA, various aspects of Medicare Advantage and Medicare supplement plans are affected, particularly concerning the standardization of plans and ensuring beneficiaries receive adequate coverage options. This legislation impacts carriers offering these supplementary plans by establishing rules that govern how they operate within the Medicare framework, including changes to benefits and cost-sharing responsibilities for beneficiaries.

The other options do not accurately reflect the scope of MACRA. It is not applicable to all healthcare providers in the U.S., nor does it extend to state Medicaid programs, as it is specifically tailored to Medicare-related coverage and its administration.
