The A, B, C & D of Medicare

The A, B, C & D of Medicare
Breaking down the basics & what each part covers

Whether your 65th birthday is on the horizon or decades away, you should understand the parts of Medicare — what they cover and where they come from.¹

Parts A & B: Original Medicare
There are two components. Part A is hospital insurance. It provides coverage for inpatient stays at medicare facilities. It can also help cover the costs of hospice care, home health care, and nursing home care — but not for long and only under certain parameters.¹ ²

Seniors are frequently warned that Medicare will only pay for a maximum of 100 days of nursing home care (provided certain conditions are met). Part A is the part that does so. Under current rules, you pay $0 for days 1-20 of the skilled nursing facility (SNF) care under Part A. During days 21-100, a $170.50 daily coinsurance payment may be required of you.²

Part B is medical insurance and can help pick up some of the tab for physical therapy, physician services, expenses for durable medical equipment (hospital beds, wheelchairs), and other medical services, such as lab tests and a variety of health screenings.

Part B isn’t free. You pay monthly premiums to get it and a yearly deductible (plus 20% of costs). The premiums vary according to the Medicare recipients’ income level. The standard monthly premium amount is $135.50 this year. The current yearly deductible is $185. (Some people automatically receive Part B coverage, but others must sign up for it.)³

Part C: Medicare Advantage plans. Insurance companies offer these Medicare-approved plans. To keep up your Part C coverage, you must keep up your payment of Part B premiums as wells as your Part C premiums. To say not all Part C plans are alike is an understatement. Provider networks, premiums, copays, coinsurance, and out-of-pocket spending limits can all vary widely, so shopping around is wise. During Medicare’s annual Open Enrollment Period (October 15-December 7), seniors can choose to switch out of Original Medicare to a Medicare Advantage plan or vice versa; although, any such move is much wiser with a Medigap policy already in place. ⁴ ⁵

How does a Medigap plan differ from a Part C plan? Medigap plans (also called Medicare Supplement plans) emerged to address the gaps in Part A and Part B coverage. If you have Part A and Part B in place, a Medigap policy can pick up some copayments, coinsurance, and deductibles for you. You pay Part B premiums in addition to Medigap plan premiums to keep a Medigap policy in effect. These plans no longer offer prescription drug coverage. ⁶

Part D: prescription drug plans. While Part C commonly offer prescription drug coverage, insurers also sell Part D plans a standalone product to those with Original Medicare. As per Medigap and Part C coverage, you need to keep paying Part B premiums in addition to premiums for the drug plan to keep Part D coverage going. ⁷

Every Part D plan has a formulary, a list of medications covered under the plan. Most Part D plans rank approved drugs into tiers by costs. The good news is that Medicare’s website will determine the best Part D plan for you. Go to medicare.gov/find-a-plan to start your search; enter your medications and the website will do the legwork for you.⁸
