The main purpose of this legislation is to improve the regulation of independent agents, brokers, and third-party marketing organizations involved in the Medicare program. It aims to protect Medicare beneficiaries from misleading marketing practices and ensure that agents and brokers are properly defined and regulated. Key provisions of the legislation include several important actions. First, the Secretary of Health and Human Services is required to update the definition of a third-party marketing organization to better distinguish it from independent agents and brokers.
