Medicare Part D provides prescription drug coverage for Medicare beneficiaries. Offered through private insurance companies approved by Medicare, Part D helps cover the cost of medications, reducing out-of-pocket expenses for both brand-name and generic drugs. Beneficiaries can enroll in a stand-alone Part D plan if they have Original Medicare (Parts A and B) or choose a Medicare Advantage plan that includes drug coverage. While plans vary, all must meet minimum coverage standards, and beneficiaries pay a monthly premium along with potential copayments, deductibles, or coinsurance based on the specific medications. Part D helps Medicare recipients manage medication costs, promoting better health outcomes through accessible treatment options.
