Confused About Medicare? You're Not Alone.

Original Medicare is the government program: Part A (hospital) and Part B (doctor and outpatient care). You can see any doctor or hospital in the country that accepts Medicare, with no networks and no referrals. On its own it doesn't include prescription drugs or extras like dental and vision, and it has no yearly cap on what you pay out of pocket. That's why many people add a Part D drug plan and a Medigap policy alongside it.

Medicare Advantage (Part C) is an all-in-one plan from a private insurer approved by Medicare. It bundles Part A and Part B, usually includes drug coverage, and often adds extras like dental, vision, hearing, and fitness. Premiums are frequently low or even $0, but you use a network of providers, may need referrals or prior approval, and pay copays as you go. Every Advantage plan has a yearly out-of-pocket maximum that protects you from runaway costs.

Which one fits you depends on your doctors, your medications, how much you travel, and whether you prefer steady premiums or paying as you use care. Neither is best for everyone. That's exactly the kind of thing a licensed expert can compare for your situation.

There's no single price. Your total depends on the parts you choose. Here's how the pieces fit together:

• Part A (hospital): $0 per month for most people (if you or a spouse paid Medicare taxes for about 10 years). You pay a hospital deductible only when you're admitted.
• Part B (medical): a standard monthly premium set each year, plus a yearly deductible, after which you typically pay 20% of covered services. Higher earners pay a higher premium.
• Part D (drugs): a monthly premium that varies by the plan you choose. There's also an annual limit on what you'll pay out of pocket for covered drugs, after which your covered prescriptions cost $0 for the rest of the year.
• Medigap or Medicare Advantage: optional coverage that changes both your monthly cost and what you pay when you actually receive care.

For many people the biggest predictable monthly cost is the Part B premium plus a drug plan, but your real number depends on your income, your health, and the coverage you pick. A licensed expert can walk you through the current year's figures for your situation.

Your Initial Enrollment Period (IEP) is a 7-month window built around your 65th birthday: the 3 months before your birthday month, your birthday month itself, and the 3 months after.

Signing up during the first three months means your coverage can start the month you turn 65, so you avoid a gap. If you're already receiving Social Security, you're usually enrolled in Part A and Part B automatically. If not, you sign yourself up through Social Security.

Enrolling on time is the simplest way to avoid coverage gaps and lifelong late penalties. If you're still working at 65, see the question below. The timing rules can be different for you.

Often, yes. That's why timing matters so much.

• Part B penalty: if you don't sign up when first eligible (and don't have qualifying coverage from a job), your premium can rise 10% for each full 12 months you delayed, and that increase usually lasts as long as you have Part B.
• Part D penalty: going without drug coverage while you have no other "creditable" coverage adds a smaller monthly penalty that also generally lasts for life.

If you miss your window, you may have to wait for the General Enrollment Period (January 1 to March 31) to sign up. There are important exceptions, especially if you kept working and had employer coverage, so it's worth checking before you decide to delay anything.

Often, yes. If your employer has 20 or more employees and you have qualifying group coverage, you can usually delay Part B without a penalty and enroll later through a Special Enrollment Period, up to 8 months after the job or coverage ends. Two things to watch:

• Smaller employers: if your employer has fewer than 20 employees, Medicare often becomes your primary coverage, so you may need to enroll at 65 to avoid gaps.
• Health Savings Accounts (HSAs): once you're enrolled in any part of Medicare, including premium-free Part A, you can no longer contribute to an HSA. If that matters to you, plan the timing carefully.

Because the rules hinge on your employer's size and your specific plan, it's smart to confirm your situation before your 65th birthday rather than after.

Medigap (also called Medicare Supplement) is optional private insurance that works alongside Original Medicare to help pay the "gaps" it leaves, such as deductibles, copays, and the 20% coinsurance under Part B. It makes your costs more predictable and lets you keep seeing any provider that accepts Medicare.

Medigap plans are standardized by letter (like Plan G or Plan N), so the same lettered plan covers the same things no matter which company sells it, so you're mainly comparing price and service.

A couple of things to know: Medigap does not include drug coverage, so you'd add a separate Part D plan, and you can't use Medigap together with a Medicare Advantage plan. The best time to buy is your 6-month Medigap Open Enrollment window (it starts once you're 65 and enrolled in Part B), when insurers can't turn you down or charge you more for health reasons. Whether you need it comes down to how you prefer to handle cost and risk.
