The TPMO Ecosystem
Who Controls Medicare Enrollment and Why It Matters
Between the beneficiary and the plan sits an industry most seniors have never heard of. Third Party Marketing Organizations, Field Marketing Organizations, and national marketing organizations control the distribution pipeline for a significant share of Medicare Advantage enrollment. They generate leads, route calls, assign agents, and facilitate enrollments at a scale that makes them structural participants in the Medicare market rather than peripheral service providers. The DOJ’s May 2025 complaint against eHealth, GoHealth, and SelectQuote (MCR-04.03) exposed the financial arrangements underlying this pipeline. This article examines the architecture itself: who the entities are, how the money flows, why the structure incentivizes volume over quality, and what the beneficiary actually experiences on the receiving end.
The Distribution Architecture#
The Medicare enrollment distribution chain operates through a layered intermediary structure. At the top sit the national marketing organizations and field marketing organizations, which contract with MA plans to market and distribute their products. These entities recruit, train, and manage networks of licensed insurance agents. Below them, or sometimes operating independently, are Third Party Marketing Organizations, a CMS-defined category that encompasses any organization or individual that is compensated by an MA plan or Part D sponsor to perform lead generation, marketing, or enrollment activities.
The enrollment flow follows a consistent pattern. A beneficiary responds to a television advertisement, digital ad, direct mail piece, or phone solicitation. That response generates a “lead,” a record containing the beneficiary’s contact information and expressed interest in Medicare coverage. The lead is routed to a call center or assigned to a licensed agent. The agent conducts a scope of appointment, which is the CMS-required process by which the beneficiary consents to discuss specific types of coverage. The agent then presents plan options and facilitates enrollment.
The revenue model is commission-based. Plans pay agents a per-enrollment commission for each beneficiary enrolled, with the amount historically subject to CMS-set caps (now legally contested after the federal court ruling). FMOs and NMOs receive overrides, which are additional per-enrollment payments above the agent’s commission that compensate the organization for recruiting, training, and supporting its agent network. TPMOs generate revenue through lead fees, administrative payments from plans, and in some cases data monetization. The DOJ complaint alleges that some of these payments were disguised kickbacks rather than genuine service fees.
The scale of the TPMO channel is significant. While precise figures on what share of total MA enrollment flows through TPMOs versus direct plan marketing, employer groups, or SHIP counseling are not publicly reported in a single source, industry estimates suggest that a substantial majority of individual MA enrollments during the Annual Election Period involve an agent or broker, and that TPMOs and FMOs control the agent networks through which most of those enrollments occur.
Lead Generation and the Data Broker Layer#
The economics of the TPMO ecosystem begin with lead generation, and lead generation begins with advertising and data collection.
Direct-to-consumer Medicare advertising is pervasive during the AEP from October through December. Television, digital display, social media, search engine marketing, and direct mail campaigns target Medicare-eligible beneficiaries with messages about $0 premiums, dental and vision benefits, and OTC allowances. When a beneficiary responds to an advertisement by calling a number, clicking a link, or submitting a form, their contact information enters the lead pipeline.
Data brokers aggregate, score, and sell beneficiary contact information to TPMOs and agents. A “qualified” Medicare lead, meaning a beneficiary who has expressed interest and whose contact information has been verified, carries a market price that varies by quality, recency, and demographic characteristics. Dual eligible leads command premium prices because the monthly SEP creates recurring commission opportunity. The lead cost structure drives the entire downstream economics: plans pay commissions that fund TPMOs that fund lead generation. The higher the lead cost, the more enrollment volume the TPMO needs to cover its acquisition costs, which creates a structural incentive to maximize enrollment quantity rather than enrollment quality.
The “warm transfer” model accelerates the pipeline. A beneficiary calls a toll-free number from a television ad and is connected in real time to a licensed agent who begins the enrollment conversation immediately. The speed of the transfer is designed to capture the beneficiary’s interest before it dissipates. The privacy implications are often invisible to the beneficiary: by calling the number or submitting the form, the beneficiary has typically consented (through fine-print terms) to having their information shared with marketing partners, agents, and affiliated organizations. That single response can generate weeks or months of follow-up calls from multiple agents and organizations who purchased the same lead or received it through downstream distribution.
The Dual/LIS Monthly SEP as Revenue Engine#
The continuous enrollment opportunity available to dual eligible and Low-Income Subsidy beneficiaries is the structural feature that makes this population the most financially attractive segment of the Medicare enrollment market for agents and TPMOs.
Dual eligible and LIS beneficiaries can switch MA plans monthly through the integrated care Special Enrollment Period. For the non-dual beneficiary, the enrollment decision happens once a year during AEP, and the agent earns a single commission. For the dual eligible beneficiary, every month is an enrollment opportunity. An agent who switches a dual eligible beneficiary from one plan to another earns a new commission on each switch. A beneficiary switched four times in a year generates four commissions. The financial incentive to encourage switching is continuous, not seasonal, and it operates independently of whether the switch benefits the enrollee.
This creates the churn dynamic that the Senate Finance Committee is investigating (MCR-04.03). A beneficiary is contacted by an agent who recommends a different plan, often emphasizing a benefit the current plan does not offer while omitting the benefits the beneficiary would lose. The beneficiary switches. A month later, a different agent contacts the same beneficiary with a similar pitch for yet another plan. Each switch disrupts the beneficiary’s provider relationships, prescription continuity, prior authorization status, and care coordination. For a dual eligible beneficiary managing multiple chronic conditions with both Medicare and Medicaid coverage, these disruptions can have clinical consequences.
CMS has attempted to constrain this dynamic by restricting SEP elections into plans that are less integrated than the enrollee’s current plan, aiming to prevent agents from steering dual eligibles out of FIDE and HIDE SNPs into coordination-only D-SNPs or non-SNP MA plans that pay higher commissions. TPMOs have adapted by focusing enrollment activity on dual eligibles not yet in integrated plans, or by emphasizing plan features that technically satisfy the integration comparison while still generating a switch. Whether the restrictions are achieving their purpose or simply redirecting the routing is an open empirical question.
CMS Marketing Oversight#
CMS requires plans and their downstream marketing partners to follow specific rules governing scope of appointment procedures, call recording for telephonic enrollment interactions, marketing material review and approval processes, and restrictions on unsolicited contact. Plans bear responsibility for the compliance of their contracted agents and TPMOs, creating a monitoring obligation that flows down the distribution chain.
The enforcement gap between written rules and field practice is wide. CMS’s marketing compliance infrastructure relies on plan self-monitoring, beneficiary complaints through the Complaints Tracking Module, and periodic audits. The volume of enrollment interactions during AEP, numbering in the tens of millions nationally, exceeds any realistic monitoring capacity. An agent who misrepresents a plan’s network, overstates a benefit, or enrolls a beneficiary without proper scope of appointment may never be detected unless the beneficiary files a complaint, and many beneficiaries, particularly those with cognitive impairment or limited English proficiency, do not complain.
The CMS-4212-P proposed rule would relax several of these oversight mechanisms, aligning with the administration’s deregulatory posture. The industry argument is that the Biden-era rules imposed compliance costs that reduced the number of agents willing to sell MA, limiting beneficiary access to plan information. The consumer protection counter-argument is that the rules were a response to documented abuses, and that relaxing them without replacing them with alternative protections recreates the conditions that generated the abuses in the first place. The DOJ action against eHealth, GoHealth, and SelectQuote documents conduct that occurred before the Biden-era rules were in place, which suggests the problem predates the regulatory response and would likely resurface if the regulatory framework is weakened (MCR-04.03).
The Beneficiary Experience#
What enrollment through a TPMO looks like from the senior’s perspective bears little resemblance to what the regulatory architecture assumes.
A typical dual eligible beneficiary in a high-TPMO-activity market may receive dozens of unsolicited calls during AEP and additional calls throughout the year tied to the monthly SEP. The calls come from different agents representing different organizations, often using the same lead information purchased from the same data broker. The beneficiary cannot easily distinguish between an independent agent, a captive agent, a TPMO call center representative, and a plan employee. The caller identifies as someone who can “help with your Medicare benefits,” which sounds like a public service rather than a sales interaction.
Information quality varies enormously. Some agents are well trained, understand the plans they sell, and make genuine efforts to match beneficiaries with appropriate coverage. Others have minimal training, sell whichever plan pays the highest commission, and lack the clinical or program knowledge to evaluate whether a plan’s network includes the beneficiary’s specialists, whether the formulary covers their medications, or whether the plan’s prior authorization practices will create barriers to care they currently receive without restriction.
The switching pressure is built into the interaction. The agent’s compensation depends on completing an enrollment. The conversation is structured to move toward a decision. Urgency is created through statements about enrollment deadlines, expiring benefits, or limited availability. For a beneficiary with cognitive decline, limited health literacy, or social isolation, the pressure can produce enrollment decisions that do not reflect informed choice.
What happens after enrollment varies. Some beneficiaries are satisfied. Others discover that the plan they enrolled in does not cover their doctor, does not include their medications, or imposes prior authorization requirements on services they previously received without restriction. The complaint pipeline, through CMS’s CTM, through SHIP counselors, through congressional offices, captures only a fraction of the dissatisfaction. Many beneficiaries do not know how to complain, do not know they were enrolled inappropriately, or assume the problem is their own misunderstanding rather than a systemic failure.
The TPMO ecosystem is not incidental to Medicare Advantage. It is the mechanism through which a majority of individual enrollments occur. Its structure determines whether beneficiaries end up in plans that serve their clinical and financial needs or in plans that generate the most revenue for the intermediaries who control the distribution pipeline. The regulatory, enforcement, and deregulatory forces operating on this ecosystem simultaneously (MCR-04.03) will determine which outcome predominates.
