1Understanding Medicare Parts A and B
Medicare Part A covers hospital insurance, including inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. Most people do not pay a premium for Part A if they or their spouse paid Medicare taxes for at least 10 years. Medicare Part B covers medical insurance, including doctor visits, outpatient care, preventive services, and medical equipment. The standard Part B premium in 2025 is $185 per month, though higher earners pay more through Income-Related Monthly Adjustment Amounts (IRMAA).
2Medicare Part C: Medicare Advantage Plans
Medicare Advantage (Part C) plans are offered by private insurers as an alternative to Original Medicare. These plans must cover everything Original Medicare covers and often include additional benefits like dental, vision, hearing, and prescription drugs. Many Medicare Advantage plans have lower premiums than Original Medicare plus Medigap, but they typically have network restrictions and may require referrals for specialists. Choosing between Original Medicare and Medicare Advantage is one of the most important Medicare decisions you will make.
3Medicare Part D: Prescription Drug Coverage
Medicare Part D provides prescription drug coverage through private insurance plans. If you have Original Medicare, you need to enroll in a standalone Part D plan for drug coverage. Medicare Advantage plans often include drug coverage. Part D plans vary significantly in premiums, deductibles, and drug formularies, so it is important to compare plans based on your specific medications. The coverage gap or donut hole has been largely eliminated, but you may still pay more for drugs in this phase.
4Medigap: Supplemental Insurance
Medigap (Medicare Supplement) policies help cover costs that Original Medicare does not pay, such as deductibles, copayments, and coinsurance. Medigap plans are standardized and labeled with letters (A, B, C, D, F, G, K, L, M, N). Plan G is currently the most popular, covering nearly all out-of-pocket costs except the Part B deductible. You can only purchase Medigap if you have Original Medicare – it does not work with Medicare Advantage. The best time to buy Medigap is during your initial enrollment period when you have guaranteed issue rights.
5Medicare Enrollment Periods and Deadlines
Understanding Medicare enrollment periods is crucial to avoid penalties and coverage gaps. Your Initial Enrollment Period is a 7-month window around your 65th birthday. The General Enrollment Period runs January 1 through March 31 each year for those who missed initial enrollment. The Annual Election Period from October 15 to December 7 allows you to change Medicare Advantage or Part D plans. Special Enrollment Periods may apply if you have qualifying life events. Missing enrollment deadlines can result in permanent premium penalties.

Consider working with a Medicare specialist who can help you navigate the complexities and find the best coverage for your situation.
