Making Sense of Medicare
Medicare can be confusing. We are here to help you make sense of it.
If you are approaching age 65 or age 65+, you may be exploring Medicare coverage options. There are a few different ways to set up your Medicare coverage. Each works a little differently-and understanding those differences can help you avoid surprises later.
Your Medicare Options
Three common ways coverage is set up.
Original Medicare (Fee for Service Medicare)
- Basic coverage through Parts A & B
- Covers hospital stays and doctor visits
- Limited network restrictions; you can see any provider nationwide who accepts Medicare.
- You pay a share of costs when you receive care
- Does not include prescriptions or extra benefits
Supplemental or MediGap Coverage
- An insurance helping cover out-of-pocket costs Original Medicare will not
- Can include prescription drug coverage (Part D)
- Works alongside Original Medicare, but is purchased separately through a private health plan
- Limited network restrictions; keeps nationwide access to providers
- Often used to make costs more predictable
Medicare Advantage (Part C)
- Combines hospital, medical, and often drug coverage
- May include extra benefits Original Medicare doesn’t, like dental or vision
- Has provider networks, meaning lowest cost care option is typically from seeing an in-network provider.
- Costs and coverage vary by plan
- May require primary care referrals and/or insurance authorization before certain care can be delivered
Comparing the Options

Medicare FAQs
Can I keep my current doctor?
It depends on the type of coverage you choose.
- With Original Medicare (with or without a supplement), you can see any provider nationwide who accepts Medicare
- With Medicare Advantage, you typically need to use doctors within the plan’s network, and going outside the network may cost more
How will my costs work?
Costs are structured differently depending on your coverage.
- With Original Medicare, you pay deductibles and a share of the cost for services
- With Original Medicare + a supplement, many of those out-of-pocket costs may be covered, which can make expenses more predictable
- With Medicare Advantage, you may have lower upfront costs, but you typically pay copays or other costs as you receive care
Will I need referrals to see a specialist?
This depends on how your plan is set up.
- With Original Medicare (with or without a supplement), you can usually see specialists without a referral
- With Medicare Advantage, some plans require a referral from a primary care doctor before seeing a specialist
Do services ever need approval before they're covered?
In some cases, yes.
- With Original Medicare, most services are covered without prior approval
- With Medicare Advantage, certain services or procedures may require approval before they’re covered by insurance
What happens if I have high medical costs?
Protection from higher costs works differently depending on coverage.
- With Original Medicare alone, there is no yearly limit on what you pay
- With Original Medicare + a supplement, many out-of-pocket costs may be covered, depending on the plan
- With Medicare Advantage, plans include a yearly limit on what you spend for covered services
How do prescription drugs work?
Prescription coverage is handled differently depending on your setup.
- With Original Medicare, you can enroll in a separate Part D prescription drug plan
- With Medicare Advantage, prescription coverage is often included in the plan
What's the difference between bundling coverage and adding coverage?
There are two general approaches:
- Original Medicare + supplement + Part D → You build your coverage piece by piece
- Medicare Advantage → You get hospital, medical, and often drug coverage bundled into one plan
Each approach works differently depending on how you prefer to manage your care and costs.
