If you live in Columbia and you're turning 65, your mailbox has probably already told you. Postcards, "final notice" letters, TV ads with a celebrity and a 1-800 number. Everybody wants to be your Medicare agency.
Here's the thing. They are not all the same kind of business, and the difference matters a lot more than the logo on the letter. This guide walks through the three kinds of Medicare help you'll run into in Columbia, what each one can and can't do for you, and the questions worth asking before you hand anyone your Medicare number.
Three kinds of Medicare help in Columbia
1. A captive agent
A captive agent works for one insurance company. They can only show you that company's plans. Some are great people who know their product well. The limit is simple: if a different company has a better plan for your doctors and prescriptions, a captive agent can't sell it to you and usually won't bring it up.
You'll find captive agents through carrier websites and "find an agent" directories run by a single insurer.
2. A national call center
These are the numbers on TV and in the mail. You call, you get whoever picks up, and that person may be licensed in 40 states and have never driven down Two Notch Road. Call centers can compare several companies, but they often represent a limited set of plans, and next year you probably won't reach the same person twice.
If you've ever gotten 15 calls in a day after filling out one online form, that's how you met them.
3. An independent local Medicare broker
An independent broker is appointed with several insurance companies and can compare plans across them. A local broker also knows which plans the Columbia doctors and hospitals actually take, which matters more here than most people realize. Networks around Prisma Health Richland, Prisma Health Baptist, Lexington Medical Center, MUSC Health Columbia, and the Dorn VA don't line up neatly, and they can change from one year to the next.
That's the kind of Medicare agency we are. Mauldin Insurance Group is based in Lexington and works with people all over Columbia, from Forest Acres and Shandon to Northeast Columbia, St. Andrews, and Harbison.
Agent vs. broker: is there a difference?
In everyday conversation, not much. In South Carolina both are licensed by the Department of Insurance. People usually say "broker" when they mean someone who works with several companies instead of one. When you're shopping, the better question isn't what they call themselves. Ask how many companies they can actually quote for you in Richland and Lexington counties.
What does a Medicare agency cost you?
Nothing. Insurance companies pay agents a commission that is built into the plan's pricing. Your premium for a Medicare Advantage plan, Part D plan, or Medicare Supplement is the same whether you enroll through an agent, directly with the company, or on Medicare.gov.
What changes is who you call when something goes wrong. When a claim gets denied or your pharmacy says a drug isn't covered, it helps to have a local number that a real person answers.
What a good Medicare agency should do for you
Here's what you should expect from any agency, including us:
- Check your doctors by name. Not "Prisma is in network." Your actual primary care doctor and specialists.
- Run your prescriptions. Every drug, every dose, and which pharmacy you use. With the Part D out-of-pocket cap rising to $2,400 in 2027, drug costs still vary a lot from plan to plan before you reach it.
- Explain Medicare Advantage vs. Medicare Supplement plainly. Including the part a lot of people skip: in South Carolina, if you leave a Medicare Supplement for Medicare Advantage, you may have to pass health questions to get back.
- Get your enrollment timing right. Missing your Initial Enrollment Period or your Part B window after leaving an employer plan can mean a penalty that lasts for life.
- Review your plan every fall. Plans change every January. Your Annual Notice of Change letter arrives in late September, and the Annual Enrollment Period runs October 15 through December 7.
Red flags to watch for
- They ask for your Medicare number before they've asked about your doctors.
- They push a plan because of a "giveback" or grocery card before checking your prescriptions.
- They say they're "from Medicare." Medicare doesn't call people to sell plans.
- They can't tell you which companies they represent.
- They won't give you a direct phone number for after you enroll.
Questions to ask any Medicare agency in Columbia
- How many insurance companies can you quote in my county?
- Will you check my specific doctors and hospitals?
- Will you run all of my prescriptions through each plan?
- Who do I call if I have a claim problem next spring?
- Will you review my plan every year during open enrollment?
- Are you local, or will I talk to someone different every time?
If an agency can't answer those clearly, keep looking.
Free help is also available from the state
South Carolina has a free, unbiased counseling program called I-CARE, run through the SC Department on Aging and the regional Area Agencies on Aging. I-CARE counselors don't sell plans. They're a good resource, especially if you want a second opinion. The main difference is that a licensed agent can also enroll you and stay with you as your point of contact after the paperwork is done.

Frequently Asked Questions
What is a Medicare agency?
A Medicare agency is a licensed insurance business that helps people compare and enroll in Medicare Advantage, Medicare Supplement, and Part D prescription drug plans. An independent agency works with several insurance companies. A captive agency works for one.
Is it free to use a Medicare agency in Columbia, SC?
Yes. Agents are paid by the insurance companies, and your premium is the same whether you enroll through an agent, directly with the company, or on Medicare.gov.
What's the difference between a Medicare agent and a Medicare broker?
Both are licensed by the SC Department of Insurance. "Broker" usually means someone who represents several insurance companies instead of one. Ask how many companies they can quote in your county.
Do I need a local Medicare agent, or can I use a national call center?
You can use either. A local agent is more likely to know which Columbia doctors and hospitals are in which networks, and you'll usually reach the same person when you need help later.
Which hospitals should I check before choosing a Medicare plan in Columbia?
Most Columbia residents want to check Prisma Health Richland, Prisma Health Baptist, Lexington Medical Center, and MUSC Health Columbia. Veterans should also think about how their plan works alongside care at the Dorn VA.
Can a Medicare agency help with Medicare Supplement plans like Plan G and Plan N?
Yes. An independent agency can compare Medicare Supplement rates from several companies. Plan G and Plan N cover the same medical benefits no matter which company sells them, so price and rate history are what you're comparing.
When can I change my Medicare plan?
The Annual Enrollment Period runs October 15 through December 7, with changes taking effect January 1. There's also a Medicare Advantage Open Enrollment Period from January 1 through March 31, plus Special Enrollment Periods for things like moving or losing other coverage.
What should I bring to a Medicare review?
Your Medicare card, a list of your doctors, a list of your prescriptions with doses, your preferred pharmacy, and any letters you've received from your current plan, especially the Annual Notice of Change.
Will a Medicare agent call me without my permission?
A legitimate agent shouldn't. If someone calls out of the blue saying they're from Medicare, hang up. Medicare does not call people to sell plans.
Do you serve Forest Acres, Northeast Columbia, and St. Andrews?
Yes. We work with people throughout Columbia and Richland County, including Forest Acres, Shandon, Northeast Columbia, St. Andrews, Harbison, and Dentsville, plus Lexington County communities like Irmo, Cayce, and West Columbia.
Can I meet with someone in person?
Yes. We meet by phone, video, or in person around the Midlands. Just let us know what works for you when you call.
What is I-CARE, and should I use it instead of an agent?
I-CARE is South Carolina's free Medicare counseling program. Counselors give unbiased information but don't enroll you in plans. Plenty of people use both: I-CARE for a second opinion and an agent for plan comparison, enrollment, and ongoing service.
