Understanding Medicare: What Each Part Covers and Why It Matters
Navigating Medicare can feel overwhelming, especially as you approach retirement and want to ensure your health care needs are covered. From hospital stays to prescription drugs, each “part” of Medicare plays a different role — and knowing how they work together is essential to making smart, confident choices. In this article, we break down the basics of Medicare Parts A, B, C, and D, so you can better understand your options, anticipate potential costs, and make informed decisions about your coverage.
Breaking Down The Basics
Parts A & B: Original Medicare. There are two components. In general, Part A covers inpatient hospital care, skilled nursing facility costs, hospice, lab tests, surgery, and some home health care services. One thing to keep in mind is that, while very few beneficiaries must pay Part A premiums out of pocket, annually adjusted standard deductibles still apply.1,2
Many pre-retirees are frequently warned that Medicare will only cover a maximum of 100 days of nursing home care (provided certain conditions are met). Part A is the one with these provisions. Under the current Part A rules, you would pay $0 for days 1-20 of care in a skilled nursing facility (SNF). During days 21-100, a $209.50 daily coinsurance payment may be required of you.1
Knowing the limitations of Part A, some people look for other choices when it comes to managing the costs of extended care.
Part B covers physicians' fees, outpatient hospital care, certain home health services, durable medical equipment, and other offerings not covered by Medicare Part A.1
Part B does come with some costs, however, which are adjusted annually. The premiums vary, according to the Medicare recipient's income level, but the standard monthly premium amount is $185, and the yearly deductible is $240 for 2024.1
Part C: Medicare Advantage plans. Sometimes called "Medicare Part C," Medicare Advantage (MA) plans are often viewed as an all-in-one alternative to Original Medicare. MA plans are offered by private companies approved by the federal government. Although these plans come with standardized minimum coverage, the amount of additional protection offered can differ drastically from one person to the next. This is due to unique provider networks, premiums, copays, coinsurance, and out-of-pocket spending limits. In other words, comparing prices and services offered by different vendors may be the best way to find a Medicare Advantage plan that works for you.2
Part D: Prescription drug plans. While Medicare Advantage plans often offer prescription drug coverage, insurers also sell federally standardized Medicare Part D plans as a standalone product to those with Medicare Part A and/or Part B. Every Part D plan has its own list (i.e., a "formulary") of covered medications. Visit Medicare.gov to explore the formulary of approved drugs for your Part D plan as well as their prices, organized by tier.3
In fact, Medicare.gov is a great place to start all your research. Once there, you'll find answers to your most common questions and more information on the different Medicare plans offered in your area.
