Which one of these services is excluded from Part B coverage?

Part B of Medicare covers a variety of outpatient services, including preventative services and diagnostic tests. However, specific eye exams and the fitting of eyeglasses are excluded from this coverage. This exclusion is primarily due to the fact that routine eye exams for prescription glasses are typically considered non-essential health care rather than medical treatment. Medicare Part B may cover some eye care services related to specific medical conditions, such as cataracts or glaucoma, but the general eye exams and fitting of eyeglasses fall outside of this coverage.

In contrast, bone mass measurements, diagnostic tests for treatments, and ambulatory surgical services are generally covered under Part B, as they are considered necessary medical services that fall within the standard scope of outpatient care. Understanding this distinction helps clarify the specific exclusions within Medicare Part B and informs beneficiaries about what services they may need supplemental coverage for.
