Medicare Supplement Plan G, Explained for Arizona Seniors
What standardized Plan G benefits cover, how Plan G compares with Plan N, when underwriting can apply, and what to compare between insurers.
Read the articleWhether to use a Medicare agent or enroll direct, what an independent broker actually does, how agents get paid, and the questions to ask before you pick one in Arizona.

If you are approaching 65 in Arizona, you have probably noticed the mail. Then the television commercials, then the phone calls. Somewhere in that noise is a real question worth answering carefully: should you work with a Medicare agent at all, or just enroll on your own?
This guide lays out what an agent actually does, how they are paid, when going direct makes sense, and what to ask before you let anyone near your coverage.
An independent Medicare agent can compare options from the carriers the agent represents in your ZIP code. If you are choosing between Medicare Advantage plans, comparing Medigap letters across insurers, or checking how your prescriptions are covered, an agent can save you research time and help surface trade-offs.
Going direct may make sense if you already know which plan you want, have verified your doctors and prescriptions yourself, and are comfortable handling future reviews and service questions on your own.
This is the part most people are unsure about, so let us be direct about it.
Insurance companies generally pay agents for enrollments and ongoing service. Compensation rules differ by product, and the amount an agent or agency receives can vary by carrier, plan type, location, contract and whether an enrollment is new or a renewal. Two practical points are worth understanding:
Compensation and appointments can create different incentives, so transparency matters. Ask which carriers are represented, whether compensation differs among the options being discussed and what choices are not included in the comparison.
Not every "Medicare agent" is the same thing.
A captive agent works for one insurance company. They can be perfectly good at their job, but they can offer only that company's plans. If a different carrier has an option that better fits your doctors, the captive agent cannot offer it.
An independent broker may be appointed with multiple carriers. That can provide a broader comparison than one company's lineup, but it does not guarantee access to every carrier or every plan in your ZIP code.
When someone calls you out of the blue about Medicare, one of the most useful questions you can ask is simply: which carriers are you appointed with?
Comparing plans on paper is the easy part. The work that actually changes your outcome looks like this:
That last point is the one people underestimate. At CSG Insurance Pros we review your plan every year during the Annual Enrollment Period, alert you to changes that affect your coverage, and are available when you have questions. That is why 96% of our clients stay with us year after year.
Being fair about it: there are situations where you do not need an agent.
If you are enrolling in Original Medicare Parts A and B only, that is a Social Security transaction and you can handle it yourself. If you have already decided on a specific Medigap letter from a specific carrier and you have priced it, enrolling direct is fine. And if you have employer coverage and are simply deferring, you mostly need good information rather than an agent.
Even then, it is worth checking the rules. Deferring enrollment incorrectly can be expensive because a Part B late-enrollment penalty may continue for as long as you have Part B.
Bring these to any agent, including us:
An agent who answers all five plainly is worth talking to. An agent who avoids the first or the last one is telling you something.
Arizona seniors get targeted heavily, and some of it is outright fraud. Treat any unsolicited caller asking for your Medicare or Social Security number as a warning sign. Hang up and contact Medicare, the plan or the agency through a number you independently verify.
We have even had clients tell us that someone called claiming to be from our office and tried to switch their plan. That is why we ask clients to save our number, so you know when it really is us. Our page on false advertising and Medicare scams walks through the seven patterns we see most often.
If you want to see what is available through CSG, a licensed agent can compare plans from the carriers the agency represents in your Arizona ZIP code, check your doctors and prescriptions, and explain the trade-offs in plain language. Ask which carriers and plans are included, and compare the result with Medicare's official Plan Compare tool if you want a broader market check.
CSG does not charge a separate service fee, and there is no obligation. You can read more about the types of Medicare plans first if you would rather come in prepared, or look at when you are allowed to make changes.
