Medicare Part B is a key component of the Medicare program that addresses outpatient medical services. One of its essential features is that it requires beneficiaries to pay a monthly premium. This premium helps fund the services covered under Part B, such as doctor's visits, preventive screenings, and certain outpatient therapies. Beneficiaries who opt for Part B must be aware of this cost as it is an integral part of accessing these vital health services.

The other options may misinterpret the structure of Medicare Part B. For instance, it is not mandatory for every beneficiary to enroll in Part B, as individuals can choose to enroll based on their health care needs and personal circumstances. Additionally, contrary to the notion that it covers only hospital stays, Medicare Part B primarily focuses on outpatient care rather than inpatient services, which are covered under Part A. Lastly, Medicare Part B does cover diagnostic tests, which include lab tests, imaging, and other necessary evaluations, contradicting the implication that it does not cover such services. This highlights the importance of understanding the components and coverage details of Medicare, particularly for beneficiaries managing chronic conditions like diabetes.
