Medicare prescription drug coverage, also known as Part D, is a program offered by the federal government to help individuals with the costs of their prescription medications. It covers a wide range of prescription drugs, including brand-name and generic drugs, ensuring that beneficiaries have access to the medications they need.

The coverage is provided through private insurance companies approved by Medicare to administer the program. These insurance companies offer various drug plans that individuals can choose from, based on their specific needs and preferences.
