Shopping group health for your team
A fully insured group health plan is the traditional model of employer-sponsored coverage: a company pays a fixed monthly premium to an insurance carrier, and in exchange, the carrier pays the healthcare claims for the enrolled employees and their dependents. If a catastrophic illness hits the workforce, the carrier takes the financial loss. If the workforce is exceptionally healthy and uses no medical services, the carrier keeps the premium as profit.
For the vast majority of small to mid-size businesses in Virginia, the fully insured model is the baseline. It offers absolute financial predictability, outsources the legal and operational complexities of claims adjudication to a massive institution, and provides employees with a recognizable, standardized benefit. However, buying predictability means paying a premium for the carrier’s risk assumption, and the rules of engagement—participation minimums, contribution thresholds, and state mandates—are rigid.
This comprehensive guide dissects exactly how fully insured plans operate in Virginia. It covers the mechanical requirements placed on employers, the day-to-day administrative reality for HR teams, the regulatory landscape distinguishing small from large groups, and how to evaluate whether this traditional structure remains the optimal financial choice for your business compared to modern alternatives like ICHRA or self-funding.
To manage a health plan effectively, a business owner or HR leader must understand where the money goes and who holds the bag when things go wrong. In group health insurance, the central mechanic is the transfer of risk.
Healthcare costs are inherently volatile. A single employee requiring specialized cancer treatments or a premature infant spending two months in the NICU can generate hundreds of thousands of dollars in medical bills. In a self-funded arrangement, the employer’s own capital pays those bills directly.
In a fully insured arrangement, the employer purchases total immunity from that volatility. The premium paid to a carrier like Sentara Health Plans, Anthem HealthKeepers, or Oscar Health Insurance is a fixed, non-refundable cost. Once that monthly invoice is paid, the employer’s financial obligation to the healthcare system is finished for that billing cycle. The carrier assumes 100% of the claims risk.
Because the carrier is absorbing the possibility of catastrophic losses, fully insured premiums include inherent padding. You are paying for the actuarial value of the expected claims, plus the carrier’s administrative overhead, their profit margin, and a risk charge to cover the unknown. Over a ten-year horizon, a healthy company will mathematically pay more in fully insured premiums than they would have paid in direct claims under a self-funded model. But in exchange, the company guarantees that a sudden million-dollar medical event will not impact their balance sheet, force layoffs, or disrupt cash flow.
When evaluating different types of health insurance, business owners often encounter the term “attachment point.” An attachment point is the specific financial threshold where stop-loss insurance kicks in to reimburse an employer for claims in a self-funded or level-funded plan.
Fully insured plans do not have an attachment point. There is no stop-loss insurance for the employer to purchase because the employer is not funding the claims. The risk transfer is absolute from the first dollar of medical care. This simplifies the financial structure immensely: the HR department does not need to monitor claims funds, wait for stop-loss reimbursements, or maintain cash reserves for healthcare liabilities. The premium is simply a line-item expense on the company’s monthly profit and loss statement.
The rules governing your fully insured plan change dramatically based on the size of your workforce. The Affordable Care Act (ACA) draws a hard line between the “Small Group” market and the “Large Group” market, and Virginia strictly enforces these federal definitions.
In Virginia, a small employer is defined as a business with 1 to 50 Full-Time Equivalent (FTE) employees. A large employer is defined as a business with 51 or more FTEs.
Calculating FTEs is not as simple as counting heads. Under the ACA formula, an employee working 30 or more hours per week counts as one FTE. Part-time employee hours are aggregated to create equivalent full-time positions (e.g., two 15-hour-per-week employees equal one FTE for the purpose of market classification). You calculate your FTE count based on the previous calendar year to determine your market status for the upcoming plan year.
If your business falls into the 1-50 FTE category, your fully insured premiums are determined by “Modified Community Rating.” This is a critical consumer protection established by the ACA. Under community rating, the insurance carrier is legally prohibited from asking about your employees’ medical histories, and they cannot adjust your premiums based on the health status or past claims of your workforce.
In the Virginia small group market, carriers can only calculate your premiums based on four demographic factors:
Because of community rating, a small landscaping company with highly physical work and multiple recent surgeries will receive the exact same rate quote as a small accounting firm in the same zip code with identical employee ages. In the small group market, your rates are based on the community’s health, not your company’s health.
Once a Virginia business crosses the threshold of 51+ FTEs, they enter the large group market. Here, the rigid protections of community rating disappear, and carriers use “Experience Rating.”
In experience rating, the carrier’s underwriters actively evaluate the specific risk profile of your workforce. They will look at your company’s past claims history (if you are moving from another carrier), demographic trends, and industry risk factors. If your 60-person company had high prescription drug usage and multiple expensive hospitalizations last year, your renewal rates will reflect that specific experience. Conversely, if your workforce is exceptionally healthy and rarely utilizes the plan, you can negotiate lower rates than the community baseline.
For large groups, the fully insured premium is a direct reflection of their own workforce’s health behavior, shifting the financial incentive toward implementing corporate wellness programs and steering employees toward cost-effective care.
Insurance carriers require a balanced risk pool to remain solvent. If an employer offers a plan but only the sickest employees enroll, the carrier suffers adverse selection—they collect a fraction of the premium but pay out massive claims. To prevent this, carriers impose strict minimum requirements on Virginia employers who wish to purchase a fully insured group policy.
You cannot simply offer a health plan, pass 100% of the cost to your employees, and call it a day. In the fully insured group market, carriers mandate that the employer share the financial burden.
The universal standard requirement is that the employer must pay at least 50% of the employee-only premium for the lowest-cost plan offered.
For example, if you offer three tiers of coverage (a Bronze, Silver, and Gold plan), and the Silver plan is the lowest cost at $600 per month for a single employee, the company must contribute at least $300 per month for every enrolled employee. The employee pays the remaining $300 via payroll deduction.
Crucially, this 50% requirement generally applies only to the employee’s premium. Employers are not legally required by the carrier to contribute anything toward the cost of covering spouses or dependents, though many businesses choose to subsidize dependent coverage as a tool for talent acquisition and retention. If an employee wants to add their family to the plan, the employer can legally deduct 100% of the additional premium difference from the employee’s paycheck.
Alongside the contribution minimum, carriers demand a minimum participation rate to ensure a healthy spread of risk. In Virginia, the standard minimum participation requirement is 70% of eligible employees.
If your company has 20 eligible full-time employees, the carrier expects 14 of them to enroll. If only 8 employees want the coverage, the carrier will refuse to issue the policy, citing failure to meet minimum participation.
However, there is a critical caveat to this math: Valid Waivers.
Carriers recognize that some employees have legitimate access to coverage elsewhere. If an employee declines your plan because they are covered by their spouse’s employer plan, enrolled in Medicare, or covered by Medicaid, they submit a “valid waiver.” Employees with valid waivers are removed from the denominator when calculating your participation percentage.
Consider the math in a 20-person company:
If an employee declines coverage simply because they do not want to pay the premium and choose to remain uninsured, that is an invalid waiver. They remain in the denominator, making it harder to reach the 70% threshold.
For small businesses struggling to meet the 50% contribution or 70% participation requirements, the ACA includes a unique annual provision. Between November 15th and December 15th of every year, eligible small employers can enroll in a fully insured group health plan for a January 1st effective date without having to meet minimum participation or contribution requirements. During this one-month window, carriers must accept the group regardless of how few employees enroll or how little the employer contributes.
Health insurance is heavily regulated at both the state and federal levels. Understanding which regulatory body oversees your fully insured plan is critical for HR compliance.
Fully insured plans are governed by the state in which the policy is written. In Virginia, the regulatory authority is the State Corporation Commission (SCC) Bureau of Insurance. This is a fundamental distinction between fully insured plans and self-funded plans.
Self-funded plans are governed exclusively by federal law (ERISA) and preempt state insurance regulations. Fully insured plans must comply with both federal law and Virginia-specific insurance mandates.
The Virginia General Assembly frequently passes legislation requiring health insurance policies sold in the state to cover specific treatments, services, or conditions. These are known as State Mandated Benefits. If you purchase a fully insured group plan in Virginia, your carrier is legally required to include coverage for these mandates. Examples of Virginia state mandates include:
Because fully insured plans must absorb the cost of all state mandates, their baseline premiums are inherently higher than a comparably designed self-funded plan that chooses to exclude certain elective coverages.
While fully insured plans are subject to state regulation, they are still employee benefit plans subject to the federal Employee Retirement Income Security Act (ERISA). Business owners often mistakenly believe that because they bought a fully insured policy from a major carrier, the carrier handles all ERISA compliance. This is a dangerous misconception.
Under ERISA, the employer—not the insurance carrier—is the designated Plan Administrator. The employer is legally responsible for specific federal compliance duties, including:
One of the primary reasons businesses choose a fully insured structure over alternative funding models is the massive reduction in administrative burden on the HR department. In a fully insured setup, the division of labor between the employer and the carrier is clearly defined, with the carrier doing almost all of the heavy lifting.
When you pay your monthly fully insured premium, you are paying for an entire administrative ecosystem. The carrier is solely responsible for:
If an employee has a dispute over a $10,000 hospital bill, they call the 1-800 number on the back of their ID card. The HR department is completely insulated from protected health information (PHI) and medical billing disputes.
In a fully insured model, the employer’s HR team operates entirely at the administrative periphery. Their responsibilities are limited to enrollment, payroll, and billing reconciliation.
1. Onboarding and Eligibility When a new employee is hired, HR must track their waiting period (e.g., coverage begins on the 1st of the month following 30 days of employment). HR notifies the employee of their eligibility, collects their enrollment decisions, and enters that data into the carrier’s portal to generate an ID card.
2. Payroll Deductions and Section 125 Plans HR must configure the payroll system to accurately deduct the employee’s share of the premium. In almost all cases, this is done through a Section 125 Premium Only Plan (POP), which allows employee premiums to be deducted on a pre-tax basis, lowering the taxable income for both the employee and the employer.
3. Monthly Billing Reconciliation The carrier generates a monthly premium invoice based on the active census of employees. HR’s most critical monthly task is reconciling this invoice against actual payroll. If an employee quit mid-month, HR must ensure they are terminated in the carrier portal and that the premium is adjusted or credited on the next invoice. Paying a premium for a terminated employee because of sloppy reconciliation is a common source of financial waste.
4. Offboarding and Continuation Coverage When an employee leaves the company, HR is legally required to offer continuation of coverage.
When an employer purchases a fully insured policy, they must select both the network structure and the cost-sharing tiers they will offer to their employees.
Carriers in Virginia offer distinct network structures within their fully insured chassis, dictating how freely employees can choose their doctors.
The employer also selects the plan’s actuarial value, often categorized by metal tiers:
Many Virginia employers choose a dual-option strategy for their fully insured offering. They might offer a high-deductible Bronze plan (which acts as the baseline for the 50% employer contribution calculation) alongside a richer Gold plan. The employee can “buy up” to the Gold plan, paying 100% of the premium difference via payroll deduction. This provides flexibility to a diverse workforce without increasing the employer’s baseline financial commitment.
Understanding where a fully insured plan fits into the broader landscape of group health insurance is vital for a business owner making a long-term strategic decision.
| Feature | Fully Insured (Traditional) | Level-Funded | ICHRA (HRA) |
|---|---|---|---|
| Claims Risk | 100% Carrier Risk. No employer liability beyond the monthly premium. | Shared Risk. Employer pays up to an attachment point; stop-loss covers the rest. | No Claims Risk. Employer provides a fixed cash allowance. |
| Cost Predictability | Extremely High. Monthly premiums are fixed for a 12-month contract. | Moderate. Unused claims funds can be refunded at year-end. | Absolute. Employer sets exact monthly budget per employee class. |
| State Mandates | Subject to all Virginia SCC Bureau of Insurance mandates. | Exempt from state mandates under ERISA framework. | Employees purchase individual ACA plans, subject to mandates. |
| HR Administration | Low. Carrier handles all claims adjudication and EOBs. | Moderate. TPA handles claims, but HR monitors funding levels. | Very Low. Employees manage their own individual plan enrollments. |
| Target Audience | Baseline option for most small/mid-size businesses prioritizing stability. | Healthy groups (20-100+) looking to capture savings on good years. | Employers wanting predictable budgets without managing a group plan. |
A fully insured policy operates on a 12-month contract. The single biggest stressor for HR professionals and business owners under this model is the annual renewal cycle. Because healthcare costs (medical trend) inflate every year, you should expect your fully insured premiums to increase annually, even if your workforce hasn’t changed.
A professional renewal process in the fully insured market follows a strict timeline, generally led by the employer’s broker.
In the small group market (1-50 FTEs), there is zero room to negotiate the raw rates with the carrier because the rates are filed with and approved by the state based on community demographics. The only way to lower your premium is to change your plan design—shifting more cost to the employees by increasing deductibles or copays, or switching from a broad PPO network to a narrower HMO network.
In the large group market (51+ FTEs), a skilled broker can negotiate. If the carrier asks for a 15% increase but your claims data shows a massive drop in utilization over the last three months, the broker can argue the underwriting math and push for a single-digit increase.
Fully insured plans are safe, but safety is expensive. As a Virginia business grows, the mathematical efficiency of paying a carrier to hold 100% of the risk diminishes.
Moving to Level-Funded If a company has 30 to 50 employees, a generally healthy, younger demographic, and minimal catastrophic claims, they are likely overpaying in a community-rated fully insured plan. By moving to a level-funded model, the employer still pays a predictable monthly amount, but if the group’s claims are lower than expected, the employer receives a refund or credit at the end of the year. This is typically the first stepping stone away from full insurance.
Moving to Self-Funded For employers cresting 150 to 200 employees, the sheer volume of premium dollars being handed to a carrier makes full insurance highly inefficient. At this scale, the law of large numbers stabilizes claims risk. The employer can self-fund the plan, bypass Virginia state mandates via ERISA, customize the exact plan design, and purchase stop-loss insurance for catastrophic protection, entirely eliminating the carrier’s profit margin from their baseline costs.
Moving to ICHRA (Individual Coverage HRA) If the employer is exhausted by the annual double-digit renewal increases and the impossible task of picking one network that satisfies a diverse workforce, ICHRA is the pivot. Instead of offering a fully insured group plan, the employer sets a defined tax-free budget (e.g., $400/month), and employees use that money to buy their own individual ACA plans on the Virginia marketplace.
Launching a fully insured plan requires precision. A missed deadline or an incomplete census can delay coverage by a full month.
