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

The Four Ways to Buy a Medigap Policy

When you are 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 generally does not move based on who hands you the application.

Here is a quick overview of your options:

The key insight: the premium you pay is generally the same whether you enroll through a broker or directly through the carrier, because brokers are compensated by the insurance carriers, not by you. A few carriers offer modest direct-enrollment or online discounts (more on that below), but in most cases what changes between channels is the quality of advice and how many options you actually get to see before you commit.

How Medigap Broker Commissions Actually Work in 2026

A common worry is that working with a broker will somehow inflate your premium. It will not. 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.

Unlike Medicare Advantage and Part D, CMS does not cap or set Medigap commissions. Each carrier sets its own structure, filed at the state level. Public 2026 estimates place typical Medigap commissions at roughly 18% to 22% of first-year annualized premium, with renewals of about 2% to 10% for several years, then a step-down or service fee in later years. Some carriers use flat per-member-per-month structures instead of percentages, and a growing number of insurers are trimming or eliminating new-business Medigap commissions on certain products, while continuing to pay renewals on existing policies.

For context on how differently the other side of Medicare is regulated: in 2026, the national initial Medicare Advantage broker compensation cap rose to $694 per enrollment (up from $626 in 2025), and the renewal cap rose to $347 (up from $313). Stand-alone Part D initial commissions are capped at $114 with $57 renewals. Higher-cost regions have higher FMV amounts, including California and New Jersey at $864 initial and $432 renewal, Connecticut, Pennsylvania, and DC at $781 initial and $391 renewal, and Puerto Rico and the U.S. Virgin Islands at $474 initial and $237 renewal. None of those CMS caps apply to Medigap, but they show how differently the two markets are regulated.

If you would like a deeper look at why two carriers can charge wildly different prices for the same lettered plan, our Medicare Supplement cost guide for 2026 walks through community-rated, issue-age, and attained-age pricing.

Independent Broker vs. Captive Agent

The single biggest distinction in the Medigap sales world is whether the person you are talking to is independent or captive. A captive agent is contracted to sell for only one insurance company, while an independent broker holds appointments with many carriers and can shop across them for the consumer. Both must be licensed in your state, both complete annual training, and neither charges you a fee.

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. Captive agents are typically compensated with a mix of salary and commission tied to that single carrier's grid, while independent brokers earn commission from whichever carrier the client picks.

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. Our full Medigap plans comparison chart shows exactly which benefits each plan letter covers. That standardization is 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. Licensed independent brokers, by contrast, provide year-round enrollment support, run underwriting pre-screens, and can help troubleshoot claims issues later in the year. 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 normally the same one you would 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.

There is one notable exception to the "same price either way" rule: Humana's 2026 Medicare Supplement pages state that, depending on the state where you live, you can get 6% off your monthly premium if you enroll online, and the discount is not available in CA, CT, OH, and PA. Because that discount is available whether a broker submits your online application or you do it yourself, a good broker should still capture it on your behalf. The downside of going direct without a broker is that the carrier's representative will not tell you when a competitor offers a better deal. If you are considering Humana specifically, our Humana Medicare Supplement review breaks down where the online discount applies and how it stacks with the household discount.

If you are 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 are 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 have 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 are 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? (Telos Actuarial reported industry-wide Plan G rate hikes ranging from just over 12% to more than 26% among the six largest carriers in early 2026, so recent history really matters.)
• Is the carrier currently writing new business, or is this a closed block?
• Are there household, EFT, or online application discounts I qualify for? Medigap household discounts commonly run 5% to 12%, with Mutual of Omaha reaching 12% in most states, some Pennsylvania filings showing up to 20%, and stacked programs (household plus online enrollment) pushing total savings toward 20% to 25% at certain carriers.
• What is 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? Delaware and Indiana both added birthday rules effective January 1, 2026, and West Virginia's birthday rule takes effect June 11, 2026 with a 24-month continuous coverage requirement. Delaware allows a 30-day-before/30-day-after window to switch to any carrier at equal or lesser benefits, while Indiana provides a roughly 60-day window with the same plan letter, and New Mexico's birthday rule is scheduled to begin January 1, 2027.

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. Ask for their full legal name (as shown on the license), NPN, resident state, and lines of authority. You want to see accident and health, or health, which is the line of authority required for Medicare products.
2. Search your state Department of Insurance license lookup (search "[Your State] Department of Insurance producer lookup"). Confirm the broker shows an active license and check the "line of authority" for accident and health or health.
3. Verify on NIPR. The NIPR Producer Database (PDB) shows up-to-date licensing, appointment, and regulatory-action information across participating jurisdictions. You can search by NPN, name, or license number, and individual producers are entitled to one free Producer Report per year.
4. 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.
5. 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 is why getting a second opinion, or starting with a best Medicare Supplement plan comparison, is often worthwhile. You can also compare carrier-level financial strength and complaint data in our ranking of the best Medigap insurance companies for 2026.

Frequently Asked Questions

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

No, in nearly all cases. 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. A small number of carriers (notably Humana in most states) offer a roughly 6% online enrollment discount, and a good broker can typically apply it for you.

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 name 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, or by searching the NIPR Producer Database with their NPN.

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.

What is 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 do not want to work with any broker. Switching brokers does not change your premium or coverage in any way.
