The similarities between Medicare Advantage plan and the ACA plans through the Marketplace are straight forward. Individuals are enrolling in private ACA health insurance and the federal government is subsidizing part of the cost of the health insurance to make it affordable. One of the main differences is how the federal government reimburses the insurer. Medicare beneficiaries receive an indirect subsidy to purchase a Medicare Advantage plan according to county they live in and based on historical health care cost data. Individuals and families enrolling in a health plan through an Affordable Care Act exchange receive a subsidy based on their income.
