Which entity is responsible for processing claims for Medicare in a state?

The correct answer is Medicare, as this federal program is specifically designed to provide health insurance to eligible individuals, primarily those aged 65 and older, as well as certain younger individuals with disabilities. Medicare directly oversees the processing of claims for services provided to its beneficiaries.

In each state, Medicare contracts with various entities known as fiscal intermediaries or Medicare Administrative Contractors (MACs) that handle the processing of claims, ensuring that providers are reimbursed for services rendered to Medicare beneficiaries. This regulatory framework allows Medicare to maintain consistent and standardized operations across different states while also handling the complexities of service claims and payments.

In contrast, the other choices do not fulfill the role of claim processing for Medicare. Malpractice refers to legal claims against healthcare providers for improper treatment and does not involve claims processing. The Partnership Plan is specific to certain Medicaid programs and services, while the state's attorney general typically addresses legal issues and enforcement matters but does not engage in the processing of Medicare claims.
