ICHRA and Level Funded as Complements or Substitutes: The Strategic Confusion Most TPAs Are Making

The TPA that adds ICHRA administration to its service portfolio without answering a prior question is building a portfolio that competes with itself. The question is whether ICHRA functions as a complement to level funded, serving different employee classes for the same employer, or as a substitute, replacing level funded entirely for employers who would otherwise be level funded clients. The distinction is not semantic. It determines revenue trajectory, margin composition, and the competitive logic of the TPA’s product lineup. Most TPAs offering both models have not answered it. The confusion is costing them.

The Diagnostic Question

#

For any given employer, does ICHRA serve a distinct employee class alongside level funded, or does it replace level funded as the primary coverage arrangement?

The complement scenario has a specific structure. An employer with 45 full-time employees offers level funded to the 35 who work at its headquarters in a rating area with competitive marketplace options and adequate network access. It offers ICHRA to the 10 who work remotely across four other states, where the employer cannot practically extend a single group plan network and where individual market options in those states are reasonable. The level funded product retains the core workforce. ICHRA serves a geographically dispersed cohort that group coverage cannot efficiently serve. The TPA administers both and generates revenue from claims administration for the larger population and reimbursement processing for the smaller one.

The substitute scenario looks different. A 14-person employer is currently on level funded. At renewal, the broker recommends switching to ICHRA because the employer is frustrated with the stop loss complexity and wants simplicity. The employer converts. The TPA loses a claims administration client and gains a reimbursement processing client. This is not growth. It is conversion of higher-margin revenue to lower-margin revenue. The number on the client list stays the same. The economics of the relationship change substantially.

The Revenue and Margin Difference

#

Level funded TPA revenue is composite. Administrative fees run $25 to $50 per employee per month depending on service scope and group size. Stop loss placement may generate commission or administrative compensation from the carrier. Network access may carry a fee share. Reporting, compliance support, and renewal management are included in the overall fee but represent real operational value that sustains the relationship. The full-service level funded TPA relationship generates $40 to $65 PEPM or more when all components are considered, with margins that reflect the operational complexity the TPA is managing.

ICHRA administration revenue is simpler and substantially lower. ICHRA platforms and administrators typically charge $15 to $30 PEPM for reimbursement processing, eligibility verification, premium documentation, and compliance support. The work involves confirming that employees are enrolled in qualifying individual coverage, processing reimbursement requests against documented premium payments, and producing required plan documents and employee notices. There is no claims adjudication. There is no stop loss management. There is no network repricing. There is no renewal underwriting. The function is simple and the competitive pressure on price is high because the operational barriers to entry are low.

The margin gap is real and structural, not cyclical. A TPA whose client mix shifts from level funded to ICHRA experiences revenue compression without a corresponding reduction in fixed costs, because the infrastructure that supports level funded clients, the claims systems, the actuarial capability, the stop loss carrier relationships, the network access contracts, does not disappear when clients convert to ICHRA. The TPA pays for its level funded infrastructure and receives ICHRA processing fees.

The differentiation gap is equally significant. Level funded TPA administration is operationally complex, relationship-intensive, and difficult to replicate at quality. A good TPA’s claims accuracy, stop loss coordination discipline, reporting depth, and renewal management capability represent years of system investment and operational development. Competitors cannot easily match the best TPA’s operational quality. ICHRA administration is none of these things. Any competent vendor can process reimbursements, verify coverage documentation, and distribute plan notices. The barriers to entry are low. The switching cost for the employer is low. Price compression is the inevitable competitive dynamic.

The Segmentation Theory Most TPAs Lack

#

A TPA with clear segmentation theory can tell a broker, for any given employer, which model serves that employer and why. Without that theory, the TPA lets the broker decide, which produces inconsistent recommendations and unpredictable revenue outcomes.

The segmentation variables that determine model fit are specific and can be mapped. Group size is the first filter: employers below 10 lives cannot viably access level funded due to the actuarial credibility problem, making ICHRA (or PEO coverage, or fully insured) the appropriate recommendation. Employers in the 10-to-50 range where level funded is viable enter a second set of filters. Geographic distribution matters: an employer whose workforce is concentrated in a single rating area with adequate network access is a strong level funded candidate. An employer whose workforce is geographically dispersed across multiple states presents network and administrative complexity that ICHRA may address more efficiently for the dispersed cohort. Risk appetite matters: the employer who understands and accepts fiduciary responsibility, stop loss management, and the possibility of year-end deficit is a level funded candidate. The employer who wants complete simplicity and zero risk exposure is not.

Individual market quality in the employees’ locations filters further. An employer in a county where the marketplace has three or more carriers, competitive silver plan premiums relative to its ICHRA budget, and adequate networks across the plans available is offering employees meaningful ICHRA value. An employer in a county where a single carrier dominates, premiums are high, and network options are thin is setting up employees for a poor coverage experience regardless of the ICHRA mechanism’s technical design.

Workforce composition matters. A young, transient workforce accustomed to managing their own benefits and comfortable with individual market navigation is a stronger ICHRA fit than an older workforce with chronic conditions, high healthcare utilization, and limited tolerance for billing complexity. Employee demographics affect both the expected cost of individual market coverage and the employee experience of managing ICHRA.

The Self-Competition Problem

#

When a TPA offers both models without segmentation discipline, the models compete for the same employers rather than serving distinct populations. The broker, facing complexity and typically defaulting to the simpler recommendation, may steer toward ICHRA for employers who would be better served by level funded. ICHRA is easier to explain. There is no stop loss. There is no claims fund. There is no reconciliation. The employer sets a number, pays it monthly, and the employee manages the rest. The simplicity narrative is compelling and the broker’s path of least resistance.

But simplicity for the broker and simplicity for the employer are different things. The employer who converts from level funded to ICHRA does gain administrative simplicity at the plan level. The employer gives up cost transparency, claims data, employer-directed plan design, potential surplus return, and the ability to manage high-cost claimants through case management and specialty benefit design. The employer also shifts coverage management burden to employees who may not be equipped to manage it. For employers who valued those level funded features, the conversion is a downgrade presented as a simplification.

The TPA that allows this dynamic to play out without a segmentation framework watches its level funded book erode while its ICHRA book grows at lower margin. Total revenue may be flat or growing while the underlying economics deteriorate. The pattern is not visible in revenue line reports because ICHRA clients count the same as level funded clients until the margin differential compounds over multiple years.

What Clarity Looks Like

#

A TPA with segmentation discipline can answer the following questions for any group in its pipeline: Does this employer belong in level funded, ICHRA, fully insured, or a combination? If ICHRA is the right answer, is it because the employer lacks the scale or sophistication for level funded, or because ICHRA genuinely serves this employer’s workforce composition better? If both products are appropriate for different classes of this employer’s workforce, which classes get which product and why?

The broker relationship supports this clarity when the TPA trains its broker partners on the segmentation framework. A broker who can place employers into the right model on first submission is more valuable to those employers than one who defaults to the simpler sale. The TPA that enables better broker decision-making through clear segmentation guidance produces better outcomes for employers and more durable revenue for itself.

The ICHRA market is growing and will continue growing. The HRA Council’s 2025 data reports 1,000 percent growth since the product’s 2020 launch, with large employer adoption up 34 percent from 2024 to 2025 and small employer adoption up 18 percent. The growth is real and it will not reverse. The strategic question for every TPA is not whether to offer ICHRA but whether offering it without segmentation discipline will accelerate the conversion of level funded revenue to lower-margin ICHRA revenue faster than new level funded clients enter the book. The answer depends on whether the TPA has a theory.
