Which of the following statements about Medicare Part B is true?

Medicare Part B is designed to cover a variety of outpatient services, including physician visits, preventive services, and certain medical supplies. One important aspect of Medicare Part B is that it requires beneficiaries to pay a monthly premium to enroll in and maintain coverage. This premium is typically deducted from the beneficiary's Social Security payment. The necessity of this premium is crucial for the funding and sustainability of the program.

The other options either misrepresent the structure of Medicare Part B or imply benefits that are not accurate. For instance, while Part B does have a deductible and involves cost-sharing through coinsurance, the statement regarding free benefits or no financial obligations fails to capture the nature of the program. Understanding the financial responsibilities associated with Medicare Part B is vital for beneficiaries to effectively manage their healthcare costs.
