If you’re on Medicare, you’ve probably wondered why your bill looks the way it does. The good news is it isn’t as mysterious as it seems. In this guide we’ll walk through the main pieces of the program, show where most people spend money, and give you a few practical tricks to keep costs down.
Part A – Hospital Insurance: For most folks this part is free because you (or your spouse) paid enough Medicare taxes while working. If you haven’t earned enough credits, you’ll pay a monthly premium—usually around $500.
Part B – Medical Insurance: This covers doctor visits, labs, outpatient services and some preventive care. The standard premium for 2025 is about $170 a month, but it can rise if your income is higher. You also pay a yearly deductible (about $240) and then 20% of the approved amount for each service.
Part D – Prescription Drug Coverage: This is optional, but most people need it. Premiums vary by plan, typically $30‑$45 a month. You’ll also face a deductible (often $0‑$500) and a “donut hole” where you shoulder a larger share of drug costs until you reach catastrophic coverage.
Medicare Advantage (Part C) and Supplemental Plans: Many swap Original Medicare for a private‑run Medicare Advantage plan. Those plans bundle Part A, B, and sometimes D, charging an extra premium that can be $0‑$100+ a month. If you keep Original Medicare, a Medigap (supplemental) policy can fill the gaps, and those policies usually cost $100‑$300 a month.
1. Check the Income‑Based Premium Reduction: If your Modified Adjusted Gross Income is below a certain level, you qualify for a lower Part B premium. The reduction can shave $20‑$30 off each month.
2. Use Generic Drugs: Part D plans cover generics at a lower co‑pay. When a brand‑name drug is prescribed, ask if there’s a generic version that works just as well.
3. Shop Around for Part D: Not all plans are created equal. Use the Medicare Plan Finder to compare premiums, deductibles, and the list of covered drugs. Switching to a plan that matches your medication routine can cut costs dramatically.
4. Take Advantage of the Extra Help Program: Also called the Low‑Income Subsidy, this program can cover most of your Part D premium, deductible and co‑pays if you meet income or resource limits.
5. Stay Up‑to‑Date on Preventive Services: Medicare covers many screenings and vaccines at no cost. Getting an annual flu shot, colonoscopy or diabetes check can prevent expensive health issues down the road.
6. Consider a Medicare Advantage Plan with Low Out‑of‑Pocket Maximums: If you expect frequent doctor visits or specialist care, a plan with a modest premium but a low max out‑of‑pocket limit may end up cheaper than paying 20% coinsurance on every claim.
7. Ask About Hospital Charity Care: Some hospitals waive Part A premiums for low‑income patients. It’s worth calling the billing office to see if you qualify.
