Shopping group health for your team
A fully insured group health plan is the traditional baseline of employer-sponsored coverage. If you have ever had a job where the company provided health insurance, handed you a card with a major carrier’s logo on it, and deducted a fixed amount from your paycheck every two weeks, you were almost certainly on a fully insured plan.
For business owners and Human Resources leads in Washington, the fully insured model is defined by a complete transfer of risk. You pay a negotiated premium to an insurance carrier. In exchange, the carrier takes on the legal and financial responsibility to pay your employees’ medical claims, negotiate rates with hospitals and doctors, and administer the complexities of the plan. If three of your employees require million-dollar medical interventions in the same calendar year, your company does not pay those hospital bills—the insurance carrier does.
This financial predictability is why the vast majority of small and mid-size businesses choose to remain fully insured. However, this “easy button” for claims risk comes with a rigid set of rules regarding how the plan is priced, who regulates it, and the compliance burdens your HR department must manage. Understanding the mechanics of the fully insured framework is essential to making an informed decision about your company’s benefits strategy, protecting your bottom line, and keeping your business legally compliant.
To evaluate group health insurance, you must first understand the fundamental flow of money and liability in a fully insured contract.
In a fully insured arrangement, the employer purchases a group master policy from a commercial health insurance carrier. This contract dictates the exact plan designs available (deductibles, copayments, out-of-pocket maximums), the network of providers the employees can access, and the monthly premium the employer must remit to the carrier.
The monthly premium is typically structured as a fixed rate per covered individual, categorizing employees into rating tiers (e.g., Employee Only, Employee + Spouse, Employee + Child(ren), and Family). Once the premium is paid, the employer’s financial obligation to the carrier for that month is completely satisfied. The carrier pools the premiums collected from your company—and thousands of other companies—into a massive financial reserve. When your employees visit the doctor or pick up a prescription, the healthcare provider bills the insurance carrier directly. The carrier pays the claim out of its pooled reserves according to the rules of the plan design.
The defining characteristic of a fully insured plan is best understood by comparing it to its alternative: the self-funded (or self-insured) plan.
In a self-funded model, the employer essentially becomes the insurance company. The employer sets aside cash reserves to pay for their employees’ actual medical claims as they occur, hiring a Third-Party Administrator (TPA) simply to process the paperwork and rent a provider network. If employees have a healthy year, the employer keeps the unspent money. If employees have a catastrophic year, the employer is financially liable for those massive claims (up to a stop-loss insurance threshold).
A fully insured plan works in the exact opposite manner. The employer pays a premium that includes the carrier’s profit margin, administrative fees, taxes, and projected claims costs. If your employees have an incredibly healthy year and barely use the doctor, you do not get a refund of your premium; the carrier keeps the profit. Conversely, if your employees have an exceptionally expensive year, the carrier absorbs the loss and cannot come to you asking for more money mid-year. The carrier takes the risk, and in exchange, they keep the reward.
One of the most critical legal mechanics of a fully insured plan is its regulatory oversight. In the United States, insurance law is primarily governed at the state level. Because a fully insured group plan involves purchasing an insurance policy from a licensed carrier, that policy is heavily regulated by the state where the contract is issued.
In Washington, this regulatory body is the Office of the Insurance Commissioner (OIC). The OIC dictates what carriers can charge, what benefits they must include, and how they must treat consumers. Every fully insured policy sold in Washington must comply with all state legislative mandates. If the Washington legislature passes a law requiring health plans to cover a specific type of behavioral health therapy or a particular reproductive health service with no cost-sharing, fully insured carriers must immediately update their policies to include it.
Self-funded plans, on the other hand, are governed at the federal level under the Employee Retirement Income Security Act (ERISA). ERISA contains a “preemption clause” that explicitly exempts self-funded plans from state insurance mandates. A self-funded employer in Washington can legally choose not to cover a state-mandated benefit, because they are not technically purchasing an insurance policy; they are funding their own claims.
For the HR leader, this means that selecting a fully insured plan guarantees that your employees will receive the full suite of consumer protections and mandated benefits required by the state of Washington, but it also means your premiums will reflect the cost of providing those mandates.
The rules that govern how a fully insured plan is priced and administered change dramatically depending on the size of your company. Under the Affordable Care Act (ACA), and adopted by Washington state law, employers are divided into two distinct markets: the Small Group market and the Large Group market.
In Washington, the small group market is defined as employers with 1 to 50 Full-Time Equivalent (FTE) employees. If your company falls into this category, your fully insured plan is subject to strict ACA regulations designed to protect small businesses from being priced out of the market due to a sick workforce.
The defining feature of the small group market is Community Rating. Prior to the ACA, a small business with one employee battling cancer might see their group health premiums skyrocket by 100% or face outright denial of coverage. Today, under community rating rules, carriers are legally prohibited from looking at the health history or claims data of a small group when setting their premiums.
In the small group market, a carrier can only calculate your premiums based on three factors:
Because carriers cannot underwrite based on health status, small group rates are effectively fixed. A 35-year-old employee working for a tech startup in King County will be charged the exact same baseline premium for a specific Gold plan as a 35-year-old employee working for a bakery across the street, regardless of either company’s medical history.
Furthermore, all small group fully insured plans must cover the ACA’s ten Essential Health Benefits (EHBs), which include prescription drugs, maternity and newborn care, mental health services, emergency services, and preventive care.
If your company has 51 or more FTEs, you cross the threshold into the large group market. The rules of engagement change significantly here.
Large group fully insured plans are not subject to strict community rating. Instead, carriers use Experience Rating. This means the insurance carrier will require your company to submit a demographic census and, more importantly, your historical claims data (if you are transitioning from another carrier). The underwriters will analyze the specific health risk of your workforce. If your 60 employees are exceptionally healthy, you will be quoted a lower premium. If your workforce has a high utilization of expensive specialty drugs or a history of high-cost hospital admissions, the carrier will load those risks into your premium calculation, making your rates more expensive.
In the large group market, you also have significantly more leverage to negotiate. Because premiums are not rigidly fixed by a community rating table, your benefits broker can negotiate administrative fees, profit margins, and specific plan designs directly with the carrier’s underwriters.
Large group plans are also not strictly required to cover the ACA’s Essential Health Benefits in the exact same manner as small groups, though in practice, the vast majority of large group fully insured plans do offer comprehensive coverage that meets or exceeds those standards to satisfy the ACA’s Employer Mandate.
| Market Feature | Small Group (1-50 FTEs) | Large Group (51+ FTEs) | Notes |
|---|---|---|---|
| Rating Method | Community Rating (Age, Location only) | Experience Rating (Based on group claims history) | Small groups cannot be penalized for sick employees. |
| Essential Health Benefits (EHBs) | Must strictly cover all 10 ACA EHBs | Generally flexible, but subject to Minimum Value rules | Large groups have more freedom in plan design. |
| Underwriting Negotiation | Virtually none; rates are filed with the state | High; brokers can negotiate margin and trend | Large groups require active underwriter negotiation. |
| Medical Questionnaires | Not allowed for rating purposes | Commonly used if credible claims data is unavailable | Small group rates are blind to health status. |
Any discussion of group size must address the ACA’s Employer Shared Responsibility Provision, commonly known as the Employer Mandate. This is the federal law that dictates whether a company is legally required to offer health insurance in the first place.
An employer is considered an Applicable Large Employer (ALE) if they have 50 or more full-time equivalent employees on average during the prior calendar year. If you are an ALE, you must offer health insurance that is both “affordable” and provides “minimum value” to at least 95% of your full-time employees and their dependents up to age 26.
If an ALE fails to offer coverage, or offers coverage that does not meet the federal affordability standards, and even one employee goes to the public health insurance exchange and qualifies for a premium tax credit, the employer will face severe IRS penalties.
For HR leads managing a fully insured plan at a company hovering around the 50-employee mark, this compliance threshold is paramount. A fully insured policy from a major carrier will inherently satisfy the “minimum value” requirement (meaning the plan covers at least 60% of total allowed costs). However, the HR department is solely responsible for ensuring the “affordability” metric is met.
The IRS defines affordability annually as a specific percentage of the employee’s household income (historically hovering between 8.5% and 9.5%). Because an employer rarely knows an employee’s total household income, the IRS provides three safe harbors to prove affordability:
For fully insured large groups, HR must mathematically ensure that the employee deductions set in the payroll system comply with at least one of these safe harbors to avoid catastrophic ACA penalties.
Carriers cannot deny coverage to a small group based on health status, but they are absolutely allowed to deny coverage if a company fails to meet structural underwriting guidelines. The two most critical rules an employer must follow to secure and keep a fully insured group plan are minimum participation and minimum employer contribution.
Insurance works on the principle of the law of large numbers. A carrier needs a healthy mix of low-utilizers (healthy people who rarely go to the doctor) to subsidize the costs of high-utilizers (sick people who need extensive care).
If a carrier allows an employer to offer a plan, but only the five sickest employees in the company enroll while the twenty healthy employees decline coverage, the carrier’s risk pool for that group is completely toxic. To prevent this “adverse selection,” carriers enforce minimum participation requirements.
In Washington, most fully insured carriers require that at least 70% to 75% of your eligible employees enroll in the plan.
The key word is “eligible.” An employee who declines your company’s coverage because they are on their spouse’s employer plan, enrolled in Medicare, or covered by Medicaid has a “valid waiver.” Employees with valid waivers are removed from the denominator when calculating your participation percentage.
For example, if you have 20 full-time employees, and 5 waive coverage because they are on a spouse’s plan, your eligible pool is now 15. To hit a 75% participation requirement, you need 12 of those 15 remaining employees to enroll. If only 8 want the coverage, the carrier will refuse to issue the policy, and you will not have group health insurance.
Note on Open Enrollment Exceptions: Under federal law, there is a one-month window every year (usually from November 15 to December 15) where carriers must accept small groups for a January 1 effective date regardless of whether they meet minimum participation or contribution requirements. However, relying on this loophole forces a company into a specific, rigid renewal cycle and leaves no room for error.
Carriers also understand that the primary reason employees decline coverage is cost. If an employer offers a plan but refuses to pay any portion of the premium, very few employees will enroll, leading to the same adverse selection problem described above.
To combat this, carriers require the employer to contribute a minimum percentage toward the cost of the coverage. The industry standard requirement for fully insured plans is that the employer must pay at least 50% of the premium cost for the employee-only tier of coverage.
You are not legally or contractually required by the carrier to contribute to the cost of adding spouses or dependents to the plan (though contributing to family tiers is a standard best practice for recruitment and retention). If the employee-only premium is $600 a month, the business must pay at least $300, leaving a maximum deduction of $300 from the employee’s monthly paychecks. If the employer attempts to pay only 25%, the carrier will audit the application and decline to issue the policy.
Paying for a fully insured group health plan is one of the largest line-item expenses on a company’s P&L statement, routinely second only to payroll. Structuring how you pay those premiums is a critical strategic decision.
When an employer deducts the employee’s share of the premium from their paycheck, that deduction should almost always be made on a pre-tax basis. To legally do this, the company must establish a Section 125 Premium Only Plan (POP) document under the Internal Revenue Code.
A POP allows employees to pay for their share of the health insurance premiums with money that has not yet been subject to federal income tax, State unemployment taxes, or FICA (Social Security and Medicare) taxes.
This creates a massive dual benefit. The employee saves money by lowering their taxable income, meaning a $200 pre-tax deduction impacts their take-home pay much less than a $200 post-tax deduction would. Simultaneously, the employer saves money because they do not have to pay the 7.65% employer-matching FICA tax on the amount the employee contributed. Over the course of a year, for a company with 30 employees, a properly executed Section 125 POP can save the business thousands of dollars in payroll taxes—often more than covering the administrative cost of setting up the document itself.
Employers have a choice in how they present the fully insured offering to their staff.
The Traditional Base Plan Strategy: The employer selects a single plan—for example, a Gold HMO plan. The employer agrees to pay 75% of the premium, and the employee pays 25%. If an employee wants to add a spouse, they pay the full additional cost. This is simple to administer but can be financially volatile for the employer, because every time the carrier raises the premium at renewal, the employer’s 75% financial burden automatically increases in absolute dollar terms.
The Defined Contribution Strategy: The employer sets a fixed dollar amount they will contribute to each employee’s healthcare, rather than a percentage. The employer might say, “We will contribute $500 per month toward your health insurance.” The employer then offers a menu of three different fully insured plans from the same carrier (e.g., a high-deductible Bronze plan, a middle-tier Silver plan, and a rich Platinum plan).
If the Bronze plan costs $450 a month, the employee pays nothing, and the employer actually saves $50. If the employee chooses the Platinum plan that costs $800 a month, the employer pays their capped $500, and the employee pays the $300 difference via payroll deduction. This defined contribution model protects the employer’s budget from unexpected premium hikes while giving employees the autonomy to buy up or buy down based on their personal medical needs and budget.
A fully insured plan removes claims risk from the employer, but it does not remove the administrative burden. Managing a group health plan requires constant, rigorous oversight by the HR team or business owner.
HR is responsible for tracking when new hires become eligible for the plan. Most companies impose a waiting period (e.g., the first of the month following 30 or 60 days of employment). Under the ACA, a waiting period cannot legally exceed 90 days. HR must notify the employee of their eligibility, collect their enrollment decisions, and submit that data to the carrier before the deadline.
Missing an enrollment window means the employee cannot join the plan until the company’s next annual open enrollment, unless they experience a Qualifying Life Event (QLE) like marriage, the birth of a child, or loss of other coverage. HR must legally verify these QLEs, collecting marriage licenses or birth certificates, and process the mid-year changes with the carrier within strict 30-day windows.
Perhaps the most tedious task in fully insured administration is reconciling the monthly premium invoice. Carriers generate bills based on a snapshot of enrollment at a specific point in time. Because employees are constantly hired, fired, or changing tiers, the carrier’s bill is almost always out of sync with reality.
HR must meticulously compare the carrier’s invoice against the company’s payroll system every single month. If an employee was terminated on the 10th of the month, but the carrier billed you for the entire following month, HR must pay the bill as invoiced and then ensure a retroactive credit appears on the subsequent month’s statement. Failing to audit these bills results in companies paying thousands of dollars in “ghost premiums” for employees who no longer work there.
When an employee is terminated or resigns, they have the legal right to continue their exact fully insured health plan for up to 18 months (or longer in specific scenarios).
If your company has 20 or more employees, this is governed by federal COBRA law. HR (or a third-party COBRA administrator) must send mandated legal notices to the terminated employee within strict timeframes. The employee is responsible for paying 102% of the total premium (both the employer and employee share, plus a 2% admin fee), which they remit back to the company or the administrator, who then pays the carrier.
If your company has fewer than 20 employees, federal COBRA does not apply. Instead, Washington state law dictates a “mini-COBRA” continuation process. Understanding which legal framework applies and executing the notifications flawlessly is a major compliance requirement; failing to offer COBRA correctly can result in massive IRS excise taxes and Department of Labor audits.
A fully insured contract is effectively a one-year lease on health coverage. Every 12 months, the group must undergo a renewal process. This is the period of highest stress for HR and finance departments, as it dictates the benefits budget for the coming year.
Approximately 60 to 90 days before your plan’s anniversary date, the carrier will deliver a renewal packet. This document outlines the premiums for the next 12 months. In the fully insured market, this number almost always goes up. The increase is driven by two factors: medical trend (the general inflation of healthcare costs, hospital rates, and prescription drugs in Washington) and, for large groups, the specific claims experience of the workforce.
For employers with 1-50 employees, the renewal rate is effectively a non-negotiable decree. The carrier’s rates are community-rated and filed with the Washington OIC. The only reason a small group rate changes is because the employees have all aged by one year (moving them into slightly higher age brackets) and the carrier has adjusted their base rates for inflation.
Because small group rates cannot be negotiated, the broker’s job at renewal is to map the market. They will take your census and run quotes across every other small group carrier operating in Washington (such as Premera Blue Cross, Regence, Kaiser Permanente, or UnitedHealthcare). If your current carrier demands a 15% increase, but a competitor offers a comparable plan for only a 4% increase, the strategic move is to change carriers entirely.
For employers with 51+ employees, the initial renewal packet is an opening bid, not a final verdict. Because large group premiums are experience-rated, the carrier builds in a margin of error.
A skilled employee benefits broker will act as your advocate, requesting the anonymized claims data that the underwriter used to calculate the increase. The broker’s actuarial team will scrutinize the data. Are they penalizing you for an employee whose expensive cancer treatment has now concluded? Are they overestimating the inflation of specialty drug costs? The broker will negotiate aggressively with the carrier’s underwriting desk, frequently talking a 15% initial increase down to a 7% or 8% final increase. If the incumbent carrier will not budge, the broker will market the group’s claims data to competitor carriers to secure a better rate, using the threat of leaving as leverage.
One unique feature of the fully insured renewal cycle is the potential for an MLR rebate. Under the ACA, carriers are required to spend a minimum percentage of the premiums they collect directly on medical care and quality improvement, rather than administrative costs and profits. For small groups, this minimum Medical Loss Ratio is 80%; for large groups, it is 85%.
If an insurance carrier collects millions in premiums from Washington employers but only spends 70% of it on actual claims because it was an unusually healthy year, the law requires the carrier to issue rebate checks back to the employers to hit the 80% or 85% threshold.
When a company receives an MLR rebate check, it is not simply free cash for the business owner. Because employees contributed to the premium out of their paychecks, a proportionate share of that rebate check belongs to the employees. The HR and finance teams must carefully distribute the rebate—either by adding it to employee paychecks as taxable income, applying it as a premium holiday for a future month, or using it to enhance plan benefits—adhering strictly to federal Department of Labor guidelines.
Evaluate your company's risk tolerance and operational capacity to see if the traditional model suits your needs.
When you buy a fully insured policy, you are not just buying risk protection; you are renting the carrier’s network of doctors and hospitals. The type of network heavily dictates the employee experience. Fully insured carriers in Washington primarily offer three network architectures:
When evaluating a fully insured carrier, HR must match the network type to the workforce’s geography. A tight regional HMO might be incredibly cost-effective for a tech firm where all 40 employees live within five miles of downtown Seattle. That exact same HMO would be functionally useless for a logistics company with drivers living in rural areas across Eastern Washington where the HMO has no contracted hospitals.
Choosing how to structure your health benefits is a complex business decision. While fully insured is the default, it is not the only path. Use this logic to dictate your next steps:
If you have 1 to 50 employees: You belong in the fully insured small group market. Your focus should not be on manipulating claims risk, because community rating shields you from it. Your focus must be on cost-containment through plan design (offering a High Deductible Health Plan paired with an HSA alongside a traditional copay plan) and strictly managing your Section 125 POP compliance.
If you have 51 to 100 employees: You are in the large group market and subject to experience rating, but your risk pool is still relatively small. One employee with premature triplets can destroy your claims data and result in a massive 30% renewal increase next year. Fully insured is likely still the safest place for you, but you must aggressively use an experienced broker to negotiate underwriters down, utilizing competitor quotes as leverage.
If you have 100+ employees and a healthy, young demographic: You are at the threshold where fully insured begins to look financially inefficient. You are paying a premium that includes the carrier’s profit margin and risk charges, but your employees aren’t generating enough claims to justify the cost. At this size, HR and finance leadership should actively ask their broker to run feasibility studies for Level-Funded or traditional Self-Funded plans, allowing the company to retain the cash reserves that are currently turning into carrier profits.
