Medicare Supplement Broker vs Direct: Best Way to Buy a Medigap Plan

The Four Ways to Buy a Medigap Policy

When you're ready to enroll in a Medicare Supplement plan, you have four practical paths to choose from. Each comes with its own trade-offs, but the underlying premium for any given plan and carrier is set by the insurance company and filed with your state's department of insurance. That price doesn't move based on who hands you the application.

Here's a quick overview of your options:

The key insight: for the same Plan G from the same insurer, in the same ZIP code, with the same effective date, your monthly premium will be identical across all four channels. What changes is the quality of advice and how many options you actually get to see before you commit.

How Medigap Broker Commissions Actually Work

A common worry is that working with a broker will somehow inflate your premium. It won't. Medigap brokers are paid commissions directly by the insurance carrier, and those commissions are baked into the rates the company files with your state regulator whether you use a broker or not.

The structure is usually a higher first-year commission followed by smaller renewal commissions for as long as you keep the policy. For Medigap, carriers typically pay agents an annualized commission of roughly 20% to 22% of first-year premium, with reduced renewal rates after that. Unlike Medicare Advantage and Part D, where CMS sets a national maximum "fair market value" cap each year, Medigap commissions are set by each carrier and regulated at the state level.

Independent Broker vs. Captive Agent

The single biggest distinction in the Medigap sales world is whether the person you're talking to is independent or captive. Both must be licensed in your state, both complete annual training, and neither charges you a fee. But their incentives are very different.

An independent broker is contracted (or "appointed") with many carriers. They can pull quotes from a dozen companies for the same plan letter and show you a side-by-side comparison. Their loyalty is to keeping you as a long-term client, since they can move your business to a different carrier later if rates change.

A captive agent works for one insurance company. Even if a competing carrier offers your same Plan G at a lower premium with stronger rate history, a captive agent cannot show you that option. They are often paid a base salary plus a smaller commission, with internal sales goals tied to the company's products.

Because Medigap plans are standardized by federal law, every Plan G covers the same core benefits regardless of which company sells it. The only real differences across carriers are premium, customer service, rate-increase history, and household discounts. That's exactly why having access to many carriers matters more for Medigap than for almost any other insurance product.

What SHIP Counselors Offer (And What They Don't)

The State Health Insurance Assistance Program (SHIP) is a federally funded service available in every state that provides free, one-on-one counseling to Medicare beneficiaries. SHIP counselors are not paid by insurance companies, do not earn commissions, and cannot sell you a policy. Their job is purely educational and advocacy-focused.

A SHIP counselor can:

• Explain how Medigap, Part D, and Medicare Advantage interact
• Walk you through which standardized plan letters are sold in your state
• Show you state comparison charts of premiums by carrier
• Screen you for Medicare Savings Programs and Extra Help
• Help with claims questions, appeals, and identifying Medicare fraud

The trade-off is that SHIP cannot enroll you in a policy or make a specific carrier recommendation. They are best used alongside a broker, not instead of one. Many savvy shoppers start with SHIP to understand their options, then use an independent broker to actually enroll. If you live in a state with unique rules, our guide to Medicare Supplement plans by state explains how SHIP and state departments of insurance work together.

Online Quote Sites vs. Buying Direct From the Carrier

Online comparison sites have grown rapidly because they offer instant quotes without a sales call. Most of these sites are actually run by licensed brokerages, and submitting your information typically routes you to a licensed agent who completes the enrollment. The premium displayed online is the same one you'd get from the carrier directly.

Buying direct from the insurance company is the most common choice for people who already know exactly which plan and carrier they want. Major carriers like UnitedHealthcare/AARP, Mutual of Omaha, and Cigna/HealthSpring let you apply through their websites or 1-800 lines. The downside: the carrier's representative will not tell you that a competitor offers a better deal.

If you're switching from a Medicare Advantage plan, this decision gets more complicated because underwriting is usually involved. Our guide on how to switch from Medicare Advantage to Medigap explains why an experienced broker often pays off in that scenario.

Questions to Ask Any Medigap Broker Before Signing

A good broker welcomes tough questions. A bad one dodges them. Here are the questions that quickly reveal who you're working with.

About their business

• Are you an independent broker or captive to one carrier?
• Which insurance companies are you currently appointed with?
• How are you paid, and does your commission differ between the carriers you've shown me?
• Can I see your state insurance license number or National Producer Number (NPN)?
• Will you be my point of contact for service issues, or will I be handed off?

About the plan they're recommending

• Why did you pick this carrier over the cheapest option for the same plan letter?
• What has this company's rate increase history been over the past 3-5 years in my state?
• Is the carrier currently writing new business, or is this a closed block?
• Are there household, EFT, or online application discounts I qualify for?
• What's the company's AM Best financial strength rating?

About underwriting and timing

• Am I in my Medigap Open Enrollment Period or eligible for a guaranteed-issue right?
• If I have to go through Medigap underwriting, which of my conditions or medications could be a problem?
• Does my state have a birthday rule or annual switching window?

Red Flags and How to Verify a Broker's License

Most brokers are honest professionals, but a few use high-pressure or deceptive tactics that consumers should learn to recognize.

The good news: verifying a broker takes about five minutes online.

1. Get their full name, NPN, and agency name before sharing any personal information.
2. Search your state Department of Insurance license lookup (search "[Your State] Department of Insurance producer lookup"). Confirm the broker is actively licensed for accident and health insurance and check for disciplinary actions.
3. Verify the carrier appointment. Call the insurance company's agent services line and ask whether the broker (by NPN) is currently appointed to sell their Medigap products in your state.
4. Search for complaints. Look up the broker's name plus terms like "complaint" or "disciplinary action" on your state regulator's site.

Why do broker recommendations vary so much? Each broker has a different lineup of carrier appointments, different underwriting experience (one may know that Carrier A is friendly to a specific condition while Carrier B is strict), and different views on rate stability. Two honest brokers can recommend two different plans for the same shopper and both be reasonable. That's why getting a second opinion, or starting with a best Medicare Supplement plan comparison, is often worthwhile.

Frequently Asked Questions

Does it cost more to buy Medigap through a broker than directly from the carrier?

No. Medigap premiums are filed with your state regulator and are identical whether you enroll through a broker, an online comparison site, or directly with the insurance company. Broker commissions are paid by the carrier and built into the standard rate. You receive a free advocate at no additional cost when you use a broker.

How can I tell if an agent is independent or captive?

Ask directly: "Which insurance companies are you currently appointed with to sell Medigap?" An independent broker will rattle off five to fifteen carriers. A captive agent will name only one company, or one company plus a few affiliates. You can verify their answer by looking up their license on your state Department of Insurance website, which often lists active carrier appointments.

Are SHIP counselors better than brokers?

They serve different purposes. SHIP counselors provide free, unbiased education and cannot sell you a plan or make a specific carrier recommendation. Brokers can compare carriers, run underwriting pre-screens, and actually enroll you. Many shoppers use SHIP first to understand their options, then use an independent broker to enroll. The two work well together.

What's the difference between a Medicare agent and a Medicare broker?

In common usage the terms are often interchangeable, but technically an "agent" represents the insurance company while a "broker" represents you, the consumer. Independent brokers are appointed with multiple carriers, while captive agents are tied to one. For Medigap shopping, what matters most is whether the person can compare multiple carriers and put their recommendations in writing.

Can I switch brokers after I enroll in a Medigap plan?

Yes, but it requires paperwork. You can change the "broker of record" on your policy by submitting a request to the insurance carrier, though some companies have a waiting period before the new broker earns commissions. You can also just call the carrier directly for service if you don't want to work with any broker. Switching brokers does not change your premium or coverage in any way.
