Medicare Prescription Drug plans, also known as Medicare Part D, provide coverage for prescriptions. Part D is an optional benefit provided by private insurers, not the federal government. There are many regulations regarding the make-up of Part D plans, but plans can differ between insurance carriers, so be sure to ask questions.
Part D plans can be a stand-alone product or part of a Medicare advantage plan. As always, it is best to consult a licensed agent for your Medicare Health Plan and prescription drug needs.
