What does a Medicare Summary Notice (MSN) provide?

A Medicare Summary Notice (MSN) serves as an important document for Medicare beneficiaries, providing a comprehensive summary of healthcare services and items that have been billed to Medicare. It explains the medical services received, the amount billed by healthcare providers, what Medicare has paid, and which charges are the responsibility of the beneficiary. This makes it an essential tool for understanding healthcare expenditures and monitoring billing for accuracy, helping beneficiaries keep track of their medical care and expenses.

The other options do not accurately represent the primary function of the MSN. While monthly payments made to Medicare, medical history details, and lists of covered medications under Medicare Part D are important, they are not included in the summary provided by the MSN. Instead, the MSN focuses specifically on the services and items related to medical claims, making option B the correct choice.
