A Medicare insurance broker is a licensed professional who helps individuals understand and compare different Medicare plans, such as Medicare Advantage, Part D prescription drug plans, and Medicare Supplement (Medigap) policies. Unlike agents who represent a single insurer, brokers work with multiple insurance companies to provide unbiased guidance tailored to each client’s healthcare needs and budget. Their services are typically free to the consumer, as brokers are compensated by the insurance companies when a plan is selected.
