Medicare Drug Coverage: What’s Included, What’s Not, and How to Save
When you’re on Medicare drug coverage, the part of Medicare that helps pay for prescription medications through Part D plans. Also known as Medicare Part D, it’s not automatic—you have to enroll, and your plan choice can save you hundreds or even thousands a year. Many people assume Medicare covers all their meds, but that’s not true. Without a Part D plan or a Medicare Advantage plan that includes drug coverage, you pay full price for everything from insulin to blood pressure pills.
Not all drugs are treated the same under Medicare Part D, the federal program that subsidizes prescription drug costs for Medicare beneficiaries. Each plan has its own list—called a formulary—of covered drugs. Some plans cover generic versions only, others include brand names but charge more. And if your drug isn’t on the list? You might pay double. That’s why checking your plan’s formulary before signing up matters more than the monthly premium. Also, don’t forget about the coverage gap—the "donut hole"—where you pay more out of pocket after hitting a certain spending limit. In 2025, you’ll pay no more than 25% of the cost for both brand and generic drugs in that gap, but you still need to track your spending.
Medicare savings, the financial relief available through low-income subsidies and plan comparisons can cut your costs dramatically. If your income is low, you might qualify for Extra Help, a program that pays part or all of your premiums, deductibles, and copays. Even if you don’t think you qualify, it’s worth applying—many people miss out because they assume they earn too much. And don’t just pick the cheapest plan. A plan with a $10 monthly premium might charge $150 for your specific medication, while a $40 plan covers it for $20. The real savings come from matching your drugs to the plan, not just the price tag.
