What is one of the requirements for Medicare prescription drug plans regarding therapeutic categories?

Medicare prescription drug plans are indeed required to cover drugs in each therapeutic category. This requirement ensures that beneficiaries have access to a range of medications that can effectively treat various medical conditions. By including drugs from all therapeutic categories, plans promote comprehensive coverage, allowing beneficiaries to find appropriate prescriptions that suit their medical needs.

Covering a broad range of therapeutic categories is crucial for patient care, as it helps ensure that those enrolled in Medicare can receive necessary medications for chronic conditions, mental health issues, and other health-related needs. It ultimately fosters adherence to treatment regimens and supports better health outcomes for beneficiaries.

On the other hand, the other options suggest limitations or exclusions that do not align with Medicare's goal of providing comprehensive pharmaceutical care. The requirement for plans to cover drugs from each therapeutic category is a safeguard that ensures access to essential medications, emphasizing the importance of addressing the diverse health needs of Medicare beneficiaries.
