This legislation aims to prevent the Department of Health and Human Services (HHS) from using any previously appropriated funds to establish Medicare Advantage as the default enrollment option within the Medicare program. It specifically targets activities that would automatically deem an individual, entitled to Medicare Part A and enrolled in Part B, as having elected a Medicare Advantage (MA) plan under Part C if they fail to make an active choice. The bill ensures that beneficiaries who do not explicitly elect a plan under section 1851(e)(1) of the Social Security Act are not automatically assigned to an MA plan. This measure seeks to protect beneficiaries from default enrollment into private Medicare plans, thereby preserving their ability to make an informed and active decision regarding their healthcare coverage.
