Medicare Plans
Medicare Advantage in Chicago, IL: Part C Explained
Medicare Advantage in Chicago works through a private insurer that takes over how your claims get paid. You keep Medicare, but the plan now handles your hospital, doctor and, in most cases, prescription benefits, all under one card.
You get a lower monthly premium, but you pay copays when you actually use care, and you're tied to a provider network. In Cook County, that network is the whole game. The right plan is whichever one your doctors and hospital take.
- Lower or $0 monthly plan premium
- Yearly cap on your out-of-pocket costs
- Drug coverage usually built in
- Extras like dental, vision and hearing

Send us the doctors and hospital you want to keep. We check them against the Advantage plans we sell in your ZIP code and call you back with the answer, including which plans do not work.

Plan types
HMO or PPO in Chicago: it shows up at the specialist's office
| HMO | PPO | |
|---|---|---|
| Monthly premium | Usually lowest, often $0 | Modestly higher |
| Out-of-network care | Emergencies only | Covered at a higher cost share |
| Referrals | Usually required for specialists | Generally not required |
| Best for | Members settled with one Chicago health system | Members who split care between systems or travel |
Check the network before the premium
Northwestern Memorial, Rush University Medical Center and UChicago Medicine don't all contract with every plan every year. We check your doctors, your hospital and your pharmacy against the current directory before you sign anything.
Costs
What you actually pay under Part C in Chicago
You still pay Medicare your Part B premium. The plan itself might charge you $0 to a modest monthly fee on top of that, and then copays kick in as you use care: a fixed amount for a primary care visit, more for a specialist, more still for outpatient surgery or a hospital admission.
Your safety net is the annual out-of-pocket maximum. Hit that number and the plan covers approved in-network care free for the rest of the year. Original Medicare has no cap like that, which is why plenty of people who skip a Medigap plan land on Advantage instead.
- You keep paying your monthly Part B premium
- Copays take the place of most percentage-based coinsurance
- An annual out-of-pocket cap protects you in a bad year
- Benefits, networks and drug lists all reset every January 1
Extras
What the extra benefits are actually worth
Dental, vision and hearing
Allowances swing a lot plan to plan. A big advertised number often covers only certain services, so ask separately what a cleaning versus a crown is worth.Built-in Part D
Most Advantage plans bundle drug coverage in. Run your actual prescriptions against the formulary. Drug tiers matter more than the premium ever will.Fitness and transportation
Gym memberships, over-the-counter cards and rides to appointments show up often and are worth having if you'll actually use them.
Timing
When you can enroll in or switch Chicago Advantage plans
Most people sign up during their Initial Enrollment Period around turning 65, or during the Annual Open Enrollment Period from October 15 to December 7. Advantage members also get a window from January 1 to March 31 to make one plan change.
A move, losing employer coverage, or qualifying for Extra Help can open a Special Enrollment Period outside those dates. Already enrolled and not happy with your plan? Start with switching your plan.
Prior authorization
Prior authorization: the extra step Original Medicare skips
Advantage plans usually want prior authorization before paying for pricier services: MRI and CT imaging, outpatient surgery, skilled nursing after a hospital stay, home health, durable medical equipment, and some specialist referrals. Your doctor sends in the request, the plan says yes or no, and care sits on hold until you hear back.
Most requests get approved. Two things worth knowing: timelines differ by plan, and a denial can be appealed, first to the plan, then to an independent reviewer. When a Chicago client hits a denial, we work that appeal with them. Nobody's left to figure it out solo.
Original Medicare paired with a Medigap plan comes with almost none of this. If avoiding that friction matters more to you than a lower premium, tell us early. It changes what we recommend.
Our process
How we check a Chicago provider network
- 1
You send the list
Primary care doctor, every specialist you see, your preferred hospital, your pharmacy. Names and clinics are enough to start.
- 2
We check the current directory
Every Advantage plan we represent gets checked against your list for the current contract year, not an old directory sitting online.
- 3
We call the clinic if it's unclear
Directories get it wrong often enough that a call to the front desk is sometimes the only way to be sure.
- 4
You get a plain answer
Which plans we offer keep all your providers, which keep some of them, and what switching would actually cost you.
We don't sell every plan available in your area
Our check covers the carriers we represent. Cook County has more Advantage carriers competing for your business than most counties in Illinois, so for the full list, contact Medicare.gov, 1-800-MEDICARE, or the Illinois SHIP program.
