Why Medicare Routes Care Differently in Sterling Heights
STERLING HEIGHTS, Mich. — When you turn 65 in Sterling Heights, you face one of the biggest decisions in retirement: how to receive your Medicare coverage. Most people choose between two very different structures — Original Medicare paired with a Medigap policy, or a Medicare Advantage plan. They both work under Medicare's rules, but they route your care and your bills in very different ways.

Key takeaways
- Original Medicare is federal coverage (Parts A and B); Medigap and Part D are separate policies you add on to help fill the gaps.
- Medicare Advantage (Part C) bundles Parts A, B, and usually D into one private plan that manages your care through a network.
- In 2026, Part D has a $2,100 out-of-pocket cap and a maximum deductible of $615; in 2027, the cap is $2,400 and the maximum deductible is $700. The old "donut hole" is gone.
- The Annual Enrollment Period runs October 15 – December 7; Medicare Advantage Open Enrollment runs January 1 – March 31.
Here's a plain-language look at how those two paths are built, so you can talk to a licensed advisor or your local SHIP counselor with clearer questions.
Path one: Original Medicare plus Medigap
Original Medicare is the federal program run directly by the Centers for Medicare & Medicaid Services (CMS). It has two parts:
- Part A covers hospital stays, skilled nursing, hospice, and some home health.
- Part B covers doctor visits, outpatient care, preventive services, and durable medical equipment.
With Original Medicare, you can see any doctor or hospital in the country that accepts Medicare — no network, no referrals. But Original Medicare doesn't cover everything. You'll still owe deductibles, coinsurance, and there is no yearly cap on what you pay out of pocket.
That's where Medigap (also called Medicare Supplement Insurance) comes in. Medigap is a separate policy sold by private insurers, standardized by the federal government into lettered plans (like Plan G or Plan N). It helps pay some of the costs Original Medicare leaves behind.
Medigap does not include drug coverage, so most people on this path also buy a stand-alone Part D plan for prescriptions.
Path two: Medicare Advantage
Medicare Advantage — also called Part C — is an all-in-one alternative offered by private insurers approved by Medicare. When you enroll, the plan takes over the delivery of your Part A and Part B benefits, and most Advantage plans also include Part D drug coverage in the same package.
Advantage plans typically use provider networks (HMOs and PPOs are common), and they may require referrals or prior authorization for certain services. In exchange, they often bundle extra benefits Original Medicare doesn't cover, and they set a yearly cap on your in-network out-of-pocket costs for medical care.
Sterling Heights is in Macomb County, where a wide selection of Medicare Advantage plans and Part D plans is available. The exact number changes each year, and you can see the current count for your ZIP code using the Plan Finder at medicare.gov.
The structural difference in one sentence
On the Medigap path, the government pays your providers and a private policy helps cover what's left. On the Medicare Advantage path, a private plan is paid to manage your Medicare benefits directly.
That single structural choice affects how you access care, how you handle referrals and networks, how your prescriptions are covered, and how your out-of-pocket costs are shaped.
What's the same either way
No matter which path you pick, some things don't change:
- You still must be enrolled in Medicare Parts A and B and keep paying your Part B premium.
- Part D rules follow the same structure in 2027: a $2,400 out-of-pocket cap, a maximum $700 deductible, and three coverage phases now that the donut hole is eliminated.
- If your income is above $109,000 (single filer, 2026), you may owe an IRMAA surcharge on Part B and Part D.
- You can use the Medicare Prescription Payment Plan to spread drug costs across the year in monthly amounts.
- Enrollment windows are the same: AEP is Oct. 15 – Dec. 7, and Medicare Advantage Open Enrollment is Jan. 1 – March 31.
When you can switch paths
The decision isn't necessarily permanent, but switching later isn't always simple. You can move between Medicare Advantage and Original Medicare during AEP or the Advantage Open Enrollment Period. However, if you leave Advantage and want to pick up a Medigap policy after your initial enrollment window, insurers in many states can use medical underwriting — meaning your health history may affect whether you can buy the policy or what it costs.
That's why the choice you make when you first become eligible matters, and why it's worth a conversation with a neutral counselor before you enroll.
