Medicare Broker vs. Agent: What's the Difference?

In traditional insurance, the distinction between agent and broker is legally significant. An agent has a formal contractual relationship with one or more insurance companies and is authorized to bind coverage on their behalf. A broker represents the buyer, shops the market, and places coverage with the carrier that best fits the buyer's needs.

In Medicare, this distinction is blurred. Most people who help beneficiaries navigate Medicare call themselves agents, but many also use the term broker. CMS regulations refer to both as "agents and brokers" and apply the same rules to both.

What actually matters in Medicare: The meaningful distinction is not agent vs. broker. It is independent vs. captive.

Independent agent/broker: Represents multiple carriers and can compare plans across the full market. Their goal is to find the best plan for your specific situation.

Captive agent: Works exclusively for one carrier (for example, a Humana-only agent). They can only show you that carrier's plans. If that carrier does not have the best plan for you, a captive agent cannot tell you that.

Direct enrollment: Enrolling directly through a carrier's website or call center is equivalent to working with a captive agent. The representative works for the carrier and can only enroll you in that carrier's plans.

Understanding how Medicare agents and brokers are compensated helps you understand their incentives.

Medicare Advantage and Part D compensation: CMS sets maximum commission rates for Medicare Advantage and Part D plans. For 2026, the maximum initial enrollment commission is $611 per year for Medicare Advantage plans and $100 per year for Part D plans. Renewal commissions are approximately half the initial rate.

The same-compensation rule: CMS requires that agents receive the same compensation for enrolling you in any plan from the same carrier, regardless of which plan you choose. This prevents agents from steering you toward more expensive plans within a carrier's lineup.

Cross-carrier variation: Compensation can vary between carriers. An agent could theoretically receive more from Carrier A than Carrier B for the same type of plan. CMS monitors for steering behavior, but this potential conflict of interest is worth being aware of.

Medigap compensation: CMS does not regulate Medigap commissions. These are set by state insurance departments and vary by state and carrier. Medigap commissions are generally higher than Medicare Advantage commissions, which is one reason some agents favor recommending Medigap over Medicare Advantage.

The bottom line on compensation: You pay the same premium whether you enroll through an agent or directly with the carrier. The agent's compensation comes from the carrier. There is no financial reason to avoid using an agent, but understanding the compensation structure helps you ask the right questions.

CMS has established a set of regulations that govern how Medicare agents and brokers can market and sell plans. These regulations are designed to protect beneficiaries from misleading sales practices.

Scope of Appointment: Before discussing Medicare Advantage or Part D plans, an agent must obtain a Scope of Appointment (SOA) from you. This document specifies which types of plans you agree to discuss. An agent cannot discuss plan types not listed on the SOA.

48-hour rule: An agent must provide the SOA at least 48 hours before a scheduled appointment. Walk-in and same-day appointments are an exception.

No unsolicited contact: Agents cannot make unsolicited door-to-door visits or cold calls to Medicare beneficiaries. They can respond to requests for information.

No gifts or inducements: Agents cannot offer gifts, cash, or other inducements to influence your plan selection. Nominal gifts (under $15) are permitted in some circumstances.

Compensation disclosure: Agents must disclose that they are compensated by the carrier if you ask. They are not required to disclose the specific amount of their compensation.

If an agent violates these rules: You can report violations to 1-800-MEDICARE or to your State Health Insurance Assistance Program (SHIP). In Florida, SHIP is called SHINE (Serving Health Insurance Needs of Elders).

Whether someone calls themselves an agent or a broker, these questions will help you evaluate whether they are the right person to help you.

How many carriers do you represent? A good independent agent typically works with 5 or more carriers. If the answer is one or two, you are likely talking to a captive agent.

Are you licensed in Florida? Medicare agents must be licensed in the state where they sell. You can verify a Florida license at the Florida Department of Financial Services website.

Are you AHIP certified? The America's Health Insurance Plans certification is required for agents to sell Medicare Advantage and Part D plans. It is renewed annually.

Will you check my specific doctors and drugs across all available plans? This is the most valuable thing an agent does. An agent who does not offer to do this is not providing full service.

Will you review my coverage annually? A good agent provides ongoing support, not just help at initial enrollment.

How are you compensated? A straightforward agent will explain that they are compensated by the carriers and that your premium is the same regardless of whether you use them.

Beyond agents and brokers, there are two other sources of Medicare help worth knowing about.

SHIP counselors (SHINE in Florida): State Health Insurance Assistance Programs provide free, unbiased Medicare counseling through trained volunteers. SHINE counselors are not licensed to sell insurance and receive no compensation from carriers. They can help you understand your options, compare plans using the Medicare Plan Finder, and navigate enrollment. They are an excellent resource for beneficiaries who want unbiased information without a sales relationship.

Medicare Plan Finder (medicare.gov): The official Medicare plan comparison tool allows you to compare all available plans in your zip code, enter your medications for drug cost estimates, and enroll directly. It is the best self-service option but requires you to manually verify your doctors' network status.

Independent agent/broker: Provides the most personalized service: doctor and drug verification across all plans, enrollment assistance, and ongoing annual support. Compensated by carriers but regulated by CMS.

The right choice depends on your situation: If you want unbiased information with no sales relationship, use SHINE. If you want personalized help finding and enrolling in the best plan, use an independent agent. If you are comfortable doing the research yourself, use the Medicare Plan Finder.
