Final answer:
Customers enrolled in a Medicare Advantage plan must continue paying their premiums for Medicare Part B, which is part of the larger framework of the Patient Protection and Affordable Care Act designed to address issues such as adverse selection in the healthcare market.
Step-by-step explanation:
When a customer is enrolled in a Medicare Advantage (MA) plan, they must continue paying their premiums for Medicare Part B. Medicare Part B is an optional insurance system that covers healthcare costs outside hospital stays, such as physician services, medical tests, and outpatient visits.
Enrollees pay a monthly premium, along with deductible charges and copayments, while the government contributes to a significant portion of the costs.
The context of this question ties into the broader framework of the Patient Protection and Affordable Care Act (ACA or Obamacare), which reformed various aspects of the healthcare system, including the expansion of Medicaid and the establishment of the individual mandate.
This individual mandate requires most Americans to have health insurance, such as Medicare, Medicaid, or through private or non-profit insurers, to avoid paying a fine. The motive behind these mandates is to mitigate issues such as moral hazard and adverse selection, which can destabilize health insurance markets.
