Which of the following is a primary function of MACs or FIs?

The primary function of Medicare Administrative Contractors (MACs) or Fiscal Intermediaries (FIs) is to oversee the daily operations of Medicare. This includes processing claims, ensuring compliance with Medicare regulations, and managing provider enrollment. MACs play a crucial role in the administration of Medicare by facilitating the interaction between Medicare and healthcare providers, ensuring that services provided are appropriate and that claims are paid correctly.

Overseeing daily operations helps ensure that beneficiaries receive the correct benefits and that providers adhere to guidelines established by Medicare. This function is essential for maintaining the integrity of the Medicare program and for delivering quality healthcare services to beneficiaries.

Setting national health policy standards, providing IT services to the healthcare system, and evaluating clinical trials for new medications fall outside the direct responsibilities of MACs and FIs. These are typically handled by broader governmental agencies or separate entities focused on public health policy and clinical research.
