Let's set the stage
Carriers do not want to manage thousands of individual agents one by one. FMOs (you will also hear IMO and NMO) grew up to do that work. The carrier contracts the FMO at a top level, and the FMO brings agents and agencies in underneath it. In Medicare, CMS rules call the whole chain of people who are paid for lead generation, marketing, sales and enrollment "third party marketing organizations," a definition that expressly includes independent agents and brokers. So an FMO and every agent under it carry Medicare compliance obligations, not just the carrier.
What an FMO actually does, day to day
| Function | What it means for you |
|---|---|
| Carrier contracting | One place to request contracts with many carriers instead of chasing each one. |
| Appointments and hierarchy | Your appointments get filed and you are placed under the right agency so commissions and overrides route correctly. |
| Commission support | Someone to call when a commission is missing or a chargeback looks wrong. |
| Certification help | Reminders and links for AHIP and each carrier's product certification each plan year. |
| Training | Product, sales and compliance training. Quality varies a lot between FMOs. |
| Marketing and leads | Some FMOs offer lead programs, co-op dollars or marketing tools. Terms vary. |
| Compliance | Guidance on Medicare marketing rules, call recording and scope of appointment practices. |
Here's the thing: the contract list is not the difference
Most FMOs can get you contracted with the big national carriers. The difference is whether anyone there has built what you are trying to build. Everything Senior Insurance is still a working retail Medicare agency in Draper, Utah. We write our own business and service our own members, and we share what is working for us internally. That is what we mean on our agent info page when we say we practice what we preach. You can see the carriers we offer listed there.
Questions to ask any FMO before you sign
- Which carriers are open for new appointments in my states right now?
- Will my agency be contracted at the agency level, with my agents under me? (See agency vs agent contracting.)
- Who do I call when a commission is wrong, and how fast do they answer?
- What is your release policy if I ever leave? Get it in writing.
- Do you require me to buy leads or tools? What is optional?
- What training do you provide, and who teaches it?
FMO vs agency vs agent
An agent sells and services policies. An agency is a licensed business entity that employs or contracts agents, usually earns overrides on their production, and has a designated responsible licensed producer on its state licenses. An FMO contracts agencies and agents with carriers and supports them. Many agency owners grow into running their own downline under an FMO. Our guide to what an FMO is goes deeper on the structure.
Where ESI fits
ESI Agencies contracts agency owners first and individual agents second. Agency owners can see agency contracting with ESI; individual agents start at the path for agents. If your agency needs leads or staff, our sister companies Lead Heroes and Hire Heroes handle those, and Seven Figure CRM runs the back office.
Frequently asked questions
Do I need an FMO to sell Medicare?
You need a carrier contract, and most carriers contract independent agents through an upline such as an FMO rather than directly. An FMO also handles appointments, hierarchy placement and certification support, which is why most independent Medicare agents work through one.
Does it cost money to join an FMO?
Carriers pay FMOs for distribution, so contracting itself usually does not cost the agent a fee. Some FMOs sell optional leads, tools or training. Ask what is required and what is optional before you sign.
What is the difference between an FMO and an IMO?
The terms are used almost interchangeably. Both contract and support agents with carriers. Some firms use IMO for life and annuity focus and FMO for health and Medicare, but there is no regulatory difference in how the labels are used.
Can an agency owner get overrides through an FMO?
Yes, when the agency is contracted at the agency level and its agents are placed under it in each carrier's hierarchy. The override amounts come from the contracts, so ask for them in writing.
