Shopping group health for your team
When a business decides to offer health insurance, the decision rarely begins with picking a specific carrier or a metal tier. The foundational choice in group health insurance is the financing mechanism—deciding exactly how the business intends to pay for the healthcare its employees consume. Providing group coverage is not a single product; it is a spectrum of risk tolerance, administrative capacity, and cash-flow management.
At one end of the spectrum, an employer pays a fixed premium to an insurance carrier to make all the risk disappear entirely. At the other end, the employer effectively becomes its own insurance company, paying medical claims directly while purchasing catastrophic backup policies to limit extreme liabilities. In the middle exist hybrid models, association pools, and tax-advantaged reimbursement accounts.
This guide serves as a comprehensive structural overview of the nine major group health funding arrangements available to employers. It covers what each mechanism is, how the financials work under the hood, and precisely what type of employer profile each option is realistically built to serve.
Before evaluating the financial mechanisms of a health plan, an employer must determine the geographical requirements of their workforce. The most financially efficient health plan in the market is completely useless if the network does not reach the employees where they actually live and work.
A health insurance network is the contracted list of doctors, hospitals, and facilities that have agreed to accept a negotiated rate for services. When an employer chooses a network type, they are deciding whether their employees will have coverage outside of that specific list of contracted providers. This directly impacts the usability of the plan based on the employer’s physical footprint.
An HMO is a highly localized, geographically restrictive network. It requires employees to select a Primary Care Provider (PCP) who acts as a gatekeeper, issuing referrals for the employee to see any specialists. Most crucially, an HMO provides zero coverage for out-of-network care, except in the case of true, life-threatening emergencies.
Because the carrier can tightly control utilization and drive high patient volume to a specific, narrow list of local providers, HMOs are generally the most affordable plans an employer can buy. They are structurally ideal for a workforce that operates in a single metropolitan area. If a business operates a single-site warehouse, a local retail chain, or a centralized office where every employee lives within a 30-mile radius, an HMO delivers comprehensive coverage at the lowest possible premium.
A PPO is a broad, flexible network. It does not require a PCP, it does not require referrals to see specialists, and it explicitly includes out-of-network benefits. If an employee sees a doctor outside the contracted network, the PPO plan still pays a percentage of the bill (though the employee will face higher out-of-pocket costs and potential balance billing from the provider).
PPOs are essential for distributed workforces. Consider a regional trucking company with drivers on routes across the Pacific Northwest and the Mountain West. A driver who needs urgent, non-emergency care while in Montana cannot rely on a Washington-based HMO. They require the broad access and out-of-network safety net that a PPO provides.
An EPO sits directly between an HMO and a PPO. Like an HMO, it provides zero coverage for out-of-network care (except emergencies). Like a PPO, it does not require a PCP or specialist referrals, and the network footprint is typically much larger—often spanning nationally rather than being confined to a single county.
Fully remote workforces face a distinct network challenge. If a company is headquartered in Washington but has remote employees scattered across Texas, Florida, and Ohio, purchasing a standard Washington-based health plan will likely fail the remote employees.
A standard regional PPO might allow out-of-network care in Florida, but forcing remote employees to pay expensive out-of-network rates for their routine, local healthcare is generally an unacceptable benefit design. Employers with fully distributed workforces must seek out carriers that offer robust national network-sharing programs (where the regional carrier leases access to a nationwide provider network) or opt for entirely different funding models, like an Individual Coverage HRA, which allows remote employees to buy localized coverage in their own zip codes.
A fully insured plan is the traditional, default mechanism most people picture when they think of employer health insurance. The employer pays a fixed, non-refundable monthly premium to an insurance carrier. In exchange, the carrier assumes 100% of the financial risk. Whether the employee group generates $10,000 in medical claims or $10 million, the employer’s cost is strictly limited to their monthly premium.
The insurance carrier calculates the premium based on the group’s expected risk, plus administrative costs, taxes, and the carrier’s profit margin.
In Washington, for small groups (1 to 50 employees), carriers must use “community rating” rules dictated by the ACA. The premium can only be based on the age of the employees, their geographic location, and their tobacco use. The carrier cannot ask health questions, and they cannot charge the employer more if the workforce has a history of high medical claims, such as severe chronic illnesses.
For large groups (51 or more employees), carriers use “experience rating.” The carrier will underwrite the group by closely examining its past medical claims history, demographics, and overall health profile. If a large group has a track record of high healthcare utilization, their renewal premiums will increase accordingly.
Fully insured plans are built for employers who require absolute financial predictability and have low risk tolerance. It is the safest route. There are no surprise medical bills presented to the CFO, no volatile cash-flow months, and no complex regulatory compliance burdens regarding claims administration.
The tradeoff for this absolute safety is cost. Fully insured premiums include state premium taxes, carrier profit margins, and risk charges. Furthermore, if a fully insured employer has an incredibly healthy year and their employees use almost no medical care, the employer does not see a dime of that money back; the carrier keeps the surplus as profit.
At the opposite end of the spectrum is the self-funded plan. Instead of paying an insurance carrier to take the risk, the employer retains the risk and pays for their employees’ medical claims directly out of the company’s own cash reserves as those claims occur.
A self-funded plan consists of three separate, unbundled financial components:
Self-funding is typically viable for large employers with 200 or more employees. These groups are large enough that the mathematical law of large numbers smooths out the volatility of month-to-month medical claims.
The advantages are massive for employers who can shoulder the risk. Self-funded plans are governed by the federal Employee Retirement Income Security Act (ERISA), which preempts many state-level insurance mandates. They avoid state premium taxes (which can save 2-3% of total costs immediately), they eliminate carrier profit margins on the claims themselves, and most importantly, if the workforce is healthy, the employer keeps 100% of the unspent claims money in their own bank account.
Historically, only massive corporations could self-fund because small businesses could not survive the cash-flow volatility of a sudden $50,000 medical claim hitting the books in a single week. Level-funding was created to bridge this gap, allowing mid-sized businesses to access the financial mechanics of self-funding while retaining the predictability of a fully insured plan.
To the HR director and the CFO, a level-funded plan looks exactly like a fully insured plan. The employer pays a fixed, predictable monthly “premium.”
However, under the hood, the carrier divides that monthly payment into three buckets:
The carrier draws from the claims reserve account to pay employee medical bills. Because of the stop-loss policy built into the monthly payment, if the group’s claims exceed the reserve, the employer is never asked to pay more; the stop-loss covers the overage.
The crucial advantage occurs at the end of the plan year. If the employees were healthy and the claims reserve account was not depleted, the carrier refunds all or a portion of the leftover money back to the employer.
Level-funding is aggressively targeted at healthy mid-sized groups, typically between 25 and 100 employees. Because these plans involve risk, the carrier will underwrite the group by having employees fill out medical questionnaires before issuing a quote. If the group has a history of high medical usage, they will be denied or quoted exorbitant rates. But for a relatively healthy, young workforce, level-funding offers the predictability of a fully insured policy with the refund potential of a self-funded plan.
| Funding Option | Target Employer Size | Financial Risk to Employer | Surplus Refund Potential? |
|---|---|---|---|
| Fully Insured | Any (1+ employees) | Zero (Fixed Premium) | No. Carrier retains all surplus. |
| Level-Funded | 25 - 100+ employees | Zero (Fixed Max Liability) | Yes. Unused claims funds are returned. |
| Self-Funded | 200+ employees | Moderate to High (Capped by Stop-Loss) | Yes. Employer keeps all unspent capital. |
| Group Captive | 50 - 250 employees | Moderate (Shared Stop-Loss Risk) | Yes. Dividends on captive profits. |
A PEO fundamentally changes the legal relationship between the employer and the employee through a mechanism called co-employment. When a business partners with a PEO, the PEO becomes the employer of record for tax, payroll, and benefits purposes, while the business owner retains absolute control over daily operations, hiring, and firing.
By legally pooling the employees of hundreds of small businesses under one massive umbrella, the PEO creates a distinct “large group.” If a 10-person marketing agency joins a PEO, their employees are pooled with 50,000 other workers. The PEO uses this enormous collective bargaining power to negotiate premium rates with major insurance carriers that a 10-person company could never achieve on its own.
The employer pays for the health insurance premiums, plus a separate administrative fee to the PEO (usually calculated as a percentage of total payroll or a flat fee per employee per month) which covers HR software, payroll processing, workers’ compensation, and compliance management.
PEOs are highly effective for small businesses (typically 5 to 50 employees) that want to offer “Fortune 500” level benefits to attract top-tier talent, but lack the internal HR infrastructure to manage it.
The primary drawback is the administrative fee. The savings on the health insurance premium must outweigh the heavy cost of the PEO’s administrative charges. Furthermore, if a business eventually leaves the PEO, they lose access to that specific health plan and must re-enter the open market.
An Association Health Plan allows multiple small employers to band together to purchase health coverage as a single large group, similar in concept to a PEO, but without the legal requirement of co-employment and the heavy payroll administrative fees.
AHPs are typically organized around a common industry or geographic region—for example, a Washington state builders’ association or a regional technology council. By pooling together, the member employers bypass the strict ACA small-group community rating rules. The plan is underwritten and priced as a single, large-group self-funded or fully insured entity.
AHPs are ideal for small employers in low-risk, healthy industries who are being penalized by the community rating rules of the standard fully insured market. If an employer has a young, healthy workforce but is paying high premiums on the open market, joining an AHP allows them to be underwritten based on their actual good health. The Washington Office of the Insurance Commissioner (OIC) heavily regulates AHPs, so employers must verify that an association is fully compliant and solvent before joining.
To understand MEC policies, an employer must first understand the ACA employer mandate.
The ACA strictly dictates which employers are legally mandated to offer health insurance based on employee count.
If an ALE fails to offer coverage to at least 95% of its full-time employees, they face the ACA 4980H(a) “Sledgehammer” penalty, which is a massive fine multiplied by the entire workforce.
A MEC policy is the absolute bare minimum insurance a company can offer to legally satisfy the 4980H(a) mandate. It is a highly stripped-down “skinny plan.” It covers 100% of ACA-mandated preventive care (annual physicals, immunizations, basic screenings) but it explicitly does not cover major hospitalization, emergency room visits, or complex surgeries.
Because the coverage is so limited, the monthly premiums for a MEC plan are extraordinarily low—often under $100 per employee per month.
MEC plans are utilized by large employers in high-turnover, low-margin, or hourly-wage industries (such as staffing agencies, fast food, hospitality, and agriculture). These employers cannot afford to spend $600 a month per employee on comprehensive major medical plans, but they are large enough that they must offer something to avoid the crippling IRS mandate penalties.
Because MEC plans and High Deductible Health Plans (HDHPs) leave massive financial gaps for the employee, employers frequently pair them with supplemental coverage to soften the blow.
Supplemental plans include hospital indemnity insurance, accident policies, critical illness coverage, and standard dental and vision. These are fixed-indemnity policies. If an employee is admitted to the hospital, a hospital indemnity plan simply cuts the employee a check for a predetermined amount (e.g., $1,000 per admission, plus $200 per day), which the employee can use to pay their massive HDHP deductible.
Any employer offering a high-deductible health plan should consider offering supplemental gap coverage. It can be employer-paid, or entirely voluntary (employee-paid via pre-tax payroll deduction). It allows the employer to save money by purchasing a high-deductible major medical plan, while giving employees a mechanism to protect themselves from bankruptcy in the event of an accident.
A group captive is a highly advanced financial structure that allows mid-sized employers to safely access the benefits of self-funding by pooling their catastrophic risk with other like-minded businesses.
In a standard self-funded plan, the employer buys specific stop-loss insurance to cover massive claims. In a captive, a group of 50 to 100 separate employers band together and form their own private insurance company (the captive) to replace the middle layer of that stop-loss.
The risk is split into three layers:
If the businesses in the captive collectively have a healthy year and the captive layer is not drained by claims, the captive generates a profit, which is paid back to the business owners as a dividend.
Captives are designed for best-in-class employers with 50 to 250 employees who have strong cash flow, a long-term strategic view of healthcare, and a genuine commitment to employee wellness and risk management. Employers who join a captive are betting that they are healthier than the general market average, and they are willing to put collateral on the line to prove it in exchange for massive long-term financial returns.
For decades, the standard group insurance model required the employer to play the role of the benefit chooser. The employer had to pick one or two plans that hopefully pleased everyone—the 25-year-old single employee who wants a cheap catastrophic plan, and the 55-year-old employee with a family who wants a robust, expensive PPO.
Health Reimbursement Arrangements (HRAs) flip this model from a “defined benefit” to a “defined contribution.”
Instead of purchasing a group health plan, the employer sets a fixed monthly allowance of tax-free money (e.g., $400 per month). The employees take that money, go to the individual ACA marketplace, and purchase the exact plan that fits their own personal network and deductible needs. The employer then reimburses the employee for the premium, up to the allowance amount.
There are two primary vehicles for this:
An ICHRA is the ultimate solution for a fully remote, distributed workforce. Because each remote employee buys an individual plan in their own local zip code, the employer completely bypasses the nightmare of trying to find a single group plan network that works in ten different states. It provides absolute budget control for the CFO, and absolute plan choice for the employee.
Choosing the correct group plan architecture requires mapping your specific organizational demographics to the funding models available. No single mechanism is universally superior; efficiency is entirely dependent on alignment.
If your organization has 35 local employees, healthy demographics, and a desire to capture unspent premium dollars, Level-Funding warrants immediate exploration. If you employ a highly distributed remote workforce across multiple time zones, forcing them into a regional group plan will yield frustration; an ICHRA defined-contribution model resolves the network disparity instantly. If your workforce exceeds 200 lives, continuing to pay fully insured risk margins and state premium taxes on the open market is a structural inefficiency that a traditional Self-Funded model will resolve.
