When an employer pays a health insurance premium, that dollar begins a journey through a chain of vendors, each extracting a fee before a single claim reaches a doctor or hospital. The typical self-insured group health plan touches a broker, a managing general agent (MGA), a third-party administrator (TPA), a stop-loss carrier, a reinsurer, and often a retrocessionaire. By the time the money lands on a provider's balance sheet, only a fraction of the original premium remains. Understanding this flow is the first step toward controlling costs.

A Surgeon's Fee Crosses a Broker, an MGA, a TPA, a Stop-Loss Carrier, a Reinsurer, and a Retrocessionaire

Consider a mid-sized employer with 500 employees. The company pays roughly $8 million in annual premium to its health plan. That money does not go directly to a claims pool. Instead, it first passes through a broker who arranged the plan. The broker's commission, typically between 5% and 10%, is deducted immediately. On an $8 million premium, that is $400,000 to $800,000 before any claim is considered.

Next, the premium flows to an MGA, which underwrites the risk and handles administrative tasks such as policy issuance and premium collection. The MGA takes a fee of 2% to 5% of premium—another $160,000 to $400,000. The TPA then adjudicates claims, charging either a per-member-per-month fee or a per-claim fee. For a 500-life group, that can amount to $200,000 to $500,000 annually.

The stop-loss carrier is next. It reimburses claims above a certain attachment point, often $100,000 to $200,000 per individual. The stop-loss premium is carved out before the claims pool is funded. For a group with high-risk employees, this can consume 10% to 20% of the total premium. Then the reinsurer takes a slice of the stop-loss carrier's risk, and the retrocessionaire absorbs the tail. Each handoff generates a fee.

By the time the surgeon who performed a hip replacement submits a claim, the dollar that started as premium has already been reduced by commissions, fees, and reinsurance costs. The provider may receive only 60 to 70 cents on the dollar. The rest is overhead and profit for intermediaries.

Each Handoff Generates a Fee That Never Reaches the Provider

The broker's commission is the first and most visible deduction. For group health plans, commissions range from 3% to 8% of premium, depending on the size of the group and the complexity of the plan. Brokers argue they earn this by negotiating rates and managing the renewal process, but the fee is a fixed percentage, not tied to claim outcomes.

The MGA fee, typically 2% to 5%, covers underwriting, policy administration, and sometimes marketing. Critics say these fees are often opaque, buried in the premium structure. A 2025 industry survey by the Self-Insurance Institute of America found that MGA fees add an average of 3.2% to total plan costs. The TPA fee, meanwhile, is either a per-member-per-month charge of $20 to $40 or a per-claim fee of $50 to $150. For a group with high claim volume, TPA fees can exceed $1 million annually.

Stop-loss premiums are the largest hidden cost. The employer pays a premium to the stop-loss carrier, which is then ceded to reinsurers. The stop-loss carrier retains a portion of the risk but transfers the rest upward. Each layer of reinsurance adds a cost, often calculated as a percentage of the net premium. According to a July 2026 report from Risk & Insurance, phantom damages—inflated billed charges from third-party medical financing—are driving up liability costs and increasing the pressure on stop-loss carriers to raise premiums.

These fees are not inherently unreasonable. Each intermediary provides a service. But the cumulative effect is that only about 70% to 80% of the premium dollar ends up paying claims. The rest is consumed by the chain. Employers that do not audit these fees may be paying far more than necessary.

The Stop-Loss Carrier Holds the Real Leverage, and It Is Not the One You Pay

The stop-loss carrier is the most powerful player in the chain, yet it is invisible to most employees. The employer buys a stop-loss policy that reimburses claims above a specific attachment point, often $100,000 to $200,000 per individual. The carrier sets reserves, decides the timing of reimbursement, and establishes guidelines that the TPA must follow for large claims.

Delayed reimbursements are a common pain point. A self-insured employer pays claims out of its own cash flow until the stop-loss carrier reimburses. If the carrier takes 60 to 90 days to process a large claim, the employer may face a cash crunch. The stop-loss carrier's guidelines also dictate which medical procedures are considered medically necessary, influencing the TPA's adjudication decisions.

Consolidation is reshaping this market. In July 2026, NFP, an Aon company, acquired Total Benefits Advisors, a Cleveland-based firm specializing in employee benefits and retirement services. The deal, reported by Insurance Journal, reflects a trend of larger brokers and carriers absorbing smaller players, potentially reducing competition and increasing fees. Employers may have fewer options for stop-loss coverage, giving carriers more leverage.

The stop-loss carrier also influences the reinsurance market. By ceding risk to reinsurers, it can adjust its own exposure. But this adds another layer of indirection. Employers rarely have direct insight into the reinsurance agreements that affect their claims. A WTW report published in Risk & Insurance in July 2026 noted that confidence in risk control is eroding across the food, beverage, and agriculture sectors, partly due to the complexity of supply chain risks. Similar dynamics apply to health insurance: the more layers, the harder it is to predict costs.

Reinsurance Recoveries Add Another Layer of Indirection and Delay

Reinsurance is the insurance that insurers buy. For a stop-loss carrier, reinsurance spreads the risk of very large claims across global markets. A single claim of $1 million might be split among several reinsurers. The stop-loss carrier retains the first layer, say up to $500,000, and cedes the rest to reinsurers. But reinsurers themselves may buy retrocession—insurance for their own risk—further fragmenting liability.

Each recovery adds time. When a large claim is submitted, the stop-loss carrier must first pay the employer, then seek reimbursement from its reinsurers. If the claim exceeds the reinsurance attachment point, the reinsurer may dispute the amount or the medical necessity. Disputes over attachment points can delay payments by 30 to 90 days. In some cases, arbitration is required, prolonging the process by months.

The complexity of these arrangements means that even a straightforward claim can become mired in paperwork. A 2025 study by the International Association of Insurance Supervisors found that reinsurance disputes add an average of 45 days to claim settlement times for large group health plans. Employers are often unaware of these delays until a catastrophic claim occurs.

Transparency is rare. Employers rarely see the reinsurance contracts that govern their stop-loss coverage. Ceding commissions—fees paid to the stop-loss carrier for managing the reinsurance—are typically not disclosed. A 2024 survey by the National Association of Insurance Commissioners found that only 12% of self-insured employers review their stop-loss carrier's reinsurance agreements. The rest rely on trust.

Medical Financing Firms Inflate Charges Before the Dollar Reaches the Doctor

A growing factor in health insurance costs is the role of third-party medical financing firms. These companies offer patients loans or credit lines to pay for medical procedures, often at high interest rates. When a patient uses such financing, the provider may submit a charged amount that is significantly higher than the negotiated rate. This practice, known as phantom damages, was highlighted in a July 2026 Risk & Insurance article.

Phantom damages inflate the billed charges that insurers see. For a liability claim—such as a car accident injury—the medical provider may bill $50,000 for a procedure that would normally cost $10,000 under a health plan's negotiated rate. The difference is pure markup, driven by the financing arrangement. This raises settlement pressure on insurers and drives up premiums for everyone.

The gap between the allowed amount and the reimbursement can be substantial. For a self-insured employer, this means higher stop-loss claims and potentially higher premiums. The stop-loss carrier may argue that the inflated charges are not reasonable and deny reimbursement, leading to disputes that further delay payment to the provider.

Regulators are beginning to take notice. Some states have introduced legislation requiring disclosure of medical financing terms and limiting the amount that can be billed above the negotiated rate. But the practice remains widespread, adding another layer of cost before the dollar reaches the doctor.

How a Self-Insured Employer Can Shorten the Chain

Employers are not powerless. The first step is to audit broker compensation and MGA fees annually. Many employers do not realize that brokers receive commissions from carriers in addition to any fee paid by the employer. A transparent broker will disclose all sources of income. Negotiating a flat fee instead of a percentage can align the broker's incentives with cost control.

Direct TPA contracts with fee caps can reduce administrative costs. Instead of a per-claim fee, employers can negotiate a fixed per-member-per-month charge that covers all claims administration. This eliminates the incentive for the TPA to process more claims and encourages efficiency. Level-funded plans, which combine a self-funded approach with stop-loss insurance, can reduce the number of intermediaries by bundling services.

Demanding transparency on reinsurance ceding commissions is another tactic. Employers should ask their stop-loss carrier for a breakdown of reinsurance costs and any commissions paid. Benchmarking against industry data, such as per-employee cost trends published by the Kaiser Family Foundation, helps employers identify when their costs are out of line.

Finally, employers should consider a data-driven approach to risk management, similar to what some auto insurers have done with telematics. While telematics is not directly applicable to health insurance, the principle of data-driven risk assessment can be adapted. Wellness programs, biometric screenings, and claims data analytics can help employers identify high-risk employees and intervene early, reducing the likelihood of catastrophic claims that trigger stop-loss layers.

None of these steps eliminate the chain entirely. But by understanding how each vendor extracts value, employers can negotiate better terms and reduce the number of hands that touch the premium dollar. The goal is not to eliminate intermediaries but to ensure that each one earns its fee in proportion to the value it provides.

Trade-Offs and Counter-Arguments: Why Some Employers Accept the Chain

Not every employer seeks to shorten the chain. Some argue that the intermediaries provide essential services that justify their fees. For example, a broker with deep market knowledge may negotiate lower overall premiums that offset the commission. An MGA may offer specialized underwriting expertise that a small employer cannot replicate. The TPA's claims adjudication and customer service may reduce employee frustration and improve retention. Stop-loss carriers and reinsurers provide financial stability that allows employers to self-insure without bearing catastrophic risk alone.

Moreover, the chain can be efficient for employers with limited internal resources. A small business with 50 employees may lack the HR staff to manage claims directly. Paying a TPA and relying on a broker's guidance may be more cost-effective than building internal capabilities. The key is to understand the total cost and evaluate whether each vendor's contribution is worth the fee.

However, the lack of transparency remains a concern. Even employers who accept the chain should demand clear reporting on how each dollar is allocated. Without that, they risk overpaying for services that could be purchased more cheaply elsewhere. A 2026 survey by the Employee Benefit Research Institute found that only 30% of self-insured employers could accurately estimate the total administrative costs embedded in their premium. The rest relied on aggregate figures that obscure the true cost of each intermediary.

Another counter-argument is that consolidation may actually reduce costs for some employers. Larger brokers and carriers can achieve economies of scale, passing some savings to clients. For instance, a national broker may negotiate lower stop-loss premiums due to its volume of business. But the same consolidation can reduce competition, leading to higher fees over time. Employers must weigh the short-term savings against the long-term risk of fewer options.

Ultimately, the decision to shorten the chain depends on the employer's size, risk tolerance, and administrative capacity. A large employer with a dedicated benefits team may benefit from direct contracting with a TPA and stop-loss carrier, bypassing the broker and MGA. A smaller employer may prefer the convenience of a bundled solution from a single vendor, even if it means paying for layers they do not fully use.

Future Trends: Technology and Regulation May Reshape the Chain

Technology is beginning to disrupt the traditional vendor chain. Artificial intelligence and machine learning are being used to automate claims adjudication, reducing the TPA's per-claim cost. Some startups offer direct-to-employer platforms that combine TPA, stop-loss, and analytics in a single interface, eliminating the need for separate MGAs and brokers. These platforms promise greater transparency and lower fees, but they are still early in adoption.

Regulatory changes could also force greater transparency. The Consolidated Appropriations Act of 2021 already requires brokers and carriers to disclose certain fees and commissions. However, enforcement has been uneven, and many employers remain unaware of their rights. Future legislation may mandate standardized reporting of all intermediary costs, making it easier for employers to compare options and negotiate.

In the meantime, employers should take proactive steps. Regularly request and review the annual disclosures required by the Consolidated Appropriations Act. Ask for a breakdown of all fees, including those paid to MGAs, TPAs, stop-loss carriers, and reinsurers. Compare these fees against industry benchmarks, such as those published by the Self-Insurance Institute of America or the Kaiser Family Foundation. And consider working with a consultant who specializes in health plan cost analysis, rather than relying solely on the broker who earns commissions from the current structure.

The premium dollar's journey through six vendors is not inevitable. With diligence and negotiation, employers can redirect more of that dollar toward actual care, reducing waste and improving the value of their health benefits.
