Final answer:
Medicare Advantage plans, such as HMOs and PPOs, are 'Managed Care' alternatives to the traditional Fee-for-Service model, designed to manage costs and streamline care. They address adverse selection and moral hazard issues within Medicare and are influenced by acts like the ACA, which prevents denial of coverage for pre-existing conditions.
Step-by-step explanation:
Types of Medicare Advantage 'Managed Care' Plans
The Medicare Advantage program, also known as Medicare Part C, provides beneficiaries with an alternative to the traditional Medicare Fee-for-Service (FFS) plan. Instead of the FFS method where health care providers receive payment for each service provided, Medicare Advantage plans operate under a 'Managed Care' system. Two primary types of managed care plans under Medicare Advantage are Health Maintenance Organizations (HMOs) and Preferred Provider Organizations (PPOs).
HMO plans require patients to receive their health care services from a network of designated providers. A primary care physician usually coordinates their care and may need to provide referrals for specialist services. PPOs, on the other hand, offer more flexibility, allowing patients to see providers both in and out of the network, usually at a higher cost for out-of-network services. Both types of plans are designed to manage costs and streamline care.
In the context of Medicare Advantage, issues such as moral hazard and adverse selection can impact costs and the availability of services. These plans aim to mitigate such issues through managed care. The Patient Protection and Affordable Care Act (ACA or Obamacare) also plays a significant role by mandating coverage for pre-existing conditions, influencing the Medicare and overall health insurance landscape.
Additionally, the Medicare Prescription Drug and Modernization Act of 2003 attempted to address the gap in coverage for prescription drugs, a significant issue for many Medicare beneficiaries. Through these adjustments and the evolution of policies like the ACA, the Medicare and Medicaid systems continue to adapt to the needs of their users.
