What it is
Original Medicare is the federal health program most people become eligible for at 65. It is made up of parts, commonly Part A (hospital coverage) and Part B (medical coverage). Original Medicare does not cover everything, so many people look at additional plan types to help fill gaps.
Medicare Supplement (Medigap) plans are sold by private insurance companies and are designed to work alongside Original Medicare. They may help with some out-of-pocket costs Original Medicare leaves behind. Medicare Advantage (Part C) plans are an alternative way to receive Medicare benefits through a private plan, and many include extra benefits. Rules, networks and costs differ by plan.
Part D plans are stand-alone prescription drug plans that can be paired with Original Medicare and Medigap. Many Medicare Advantage plans include drug coverage as well. Each plan has its own list of covered drugs, called a formulary, so what is covered can vary from plan to plan. Availability varies by state and county.
How it’s traditionally been approached
Many people begin by enrolling in Original Medicare when they turn 65, then decide whether to add a Medigap plan and a Part D plan, or to choose a Medicare Advantage plan instead. Others compare options during the enrollment windows that apply to their situation.
Medigap and Medicare Advantage are built differently. Medigap generally pairs with Original Medicare and is often associated with broader provider access, while Medicare Advantage plans often use networks and may bundle extras like drug coverage. Each approach has trade-offs, and which one fits depends on a person's health needs, budget, doctors and where they live.
People losing employer coverage after 65 often review how that coverage works with Medicare and what deadlines may apply. Traditionally, people gather their doctor and prescription lists, read plan documents, and compare options through licensed agents, plan materials or counseling resources.
How the right agent may help
A licensed independent agent may help you sort through the options, explain how the pieces fit together, and clarify the differences between Medigap, Medicare Advantage and Part D. An agent may also help you understand enrollment timing so you can ask informed questions. No outcome is promised, and options vary by state and carrier.
A first conversation is usually about your situation: your age, your current coverage, the doctors you see, the medications you take and how you like to manage health costs. Bring your current insurance cards, a list of prescriptions and any policy documents. This lets the agent walk through an insurance policy review with you.
Good questions to ask include: Are you licensed for Medicare products in my state? Which plans do you represent, and which do you not? How do the networks, drug lists and out-of-pocket rules work? What happens if my needs change? Always read your plan documents and declarations yourself before deciding.
The bigger picture
Choosing Medicare coverage is about more than paperwork. It touches your access to care, your monthly budget and your peace of mind. Feeling rushed or overwhelmed is common, and taking the time to understand your options can make the decision feel steadier.
Health and finances are closely linked in this stage of life. Many people find it helpful to think about their overall wellbeing, including their care team and support network.

- Coverage, exclusions, costs, networks and plan availability vary by plan, carrier, county and state, so read your plan documents and speak with a licensed agent.
- Agents must be licensed for the specific lines of insurance they sell and in the states where they operate; one license does not cover every line or state.
- Comparing or switching plans does not guarantee savings or claim approval, and enrollment deadlines may limit when changes can be made.

Frequently asked questions
What is an insurance policy review for Medicare plans?
An insurance policy review is a walk-through of your current coverage to understand what it does and does not do. For Medicare, it may involve looking at your Original Medicare parts, any Medigap or Medicare Advantage plan, and your Part D drug coverage. A licensed agent may help explain the details, but you should also read your own policy documents.
What is the difference between Medigap and Medicare Advantage?
Medigap is a supplement that works alongside Original Medicare, while Medicare Advantage replaces how you receive Original Medicare benefits through a private plan. Medicare Advantage plans often use provider networks and may include extra benefits, and Medigap generally does not include drug coverage. Each has advantages and trade-offs depending on your needs.
Do I need a Part D plan?
Part D is the prescription drug coverage option for people with Medicare, and whether you need it depends on your medications and your other coverage. Some people already have drug coverage through another source, and some Medicare Advantage plans include it. Ask a licensed agent how timing and existing coverage may affect you.
What should I do when I turn 65?
Many people review their enrollment window and gather information about their doctors, medications and budget. Deadlines apply, so it helps to start early. A licensed agent or official Medicare resources can explain the timing that applies to you.
What if I lose employer coverage after 65?
Losing employer coverage may open a window to enroll in or change Medicare coverage, but the rules depend on your situation. Check your coverage end date and talk with a licensed agent soon so you understand any deadlines. Do not assume you can wait.
