Fully Insured: The Complete Guide to Texas

A fully insured group health plan is the traditional model of employer-sponsored coverage. The defining characteristic of this model is total risk transfer. As an employer, you pay a fixed, predetermined monthly premium to a health insurance carrier. In exchange, the carrier assumes the complete financial liability for adjudicating and paying your employees’ medical claims. If your workforce has an exceptionally healthy year, the carrier keeps the resulting profit. Conversely, if multiple employees face million-dollar diagnoses—such as complex oncology treatments or premature infant intensive care—the carrier absorbs the financial loss in its entirety. Your business is fully insulated from claims volatility.

For business owners and Human Resources leads in Texas, the fully insured model is the default baseline for employee benefits. It requires no complex reserve accounting, no stop-loss insurance negotiations, and no direct involvement in protected health information (PHI). However, deploying a fully insured plan effectively requires a sophisticated understanding of market regulations, compliance standards, minimum participation mathematics, and state-specific mandates.

This guide breaks down the precise mechanics of fully insured group health insurance in Texas, providing the actionable intelligence HR leads and finance executives need to evaluate, structure, and administer these plans.

The Core Mechanics of Risk Transfer and Premiums

To understand how a fully insured plan operates, you must understand the distinction between premium outlay and claims risk.

In alternative models like self-funding, the employer essentially acts as the insurance company, paying medical claims directly out of corporate cash flow as they occur. That exposes the company to severe monthly volatility. In a fully insured plan, the carrier prices the aggregate risk of your group into a single monthly premium. This premium is guaranteed for a 12-month contract period.

Whether your employees utilize $10,000 in healthcare services or $1,000,000 in services during that year, your company’s monthly invoice from the carrier remains exactly the same, fluctuating only when you add or terminate employees.

The Carrier’s Role

Under this arrangement, the carrier performs all heavy lifting:

1. Network Contracting: The carrier negotiates reimbursement rates with Texas hospital systems and physician groups.
2. Claims Adjudication: The carrier processes every doctor’s bill, applies the plan’s deductible and coinsurance rules, and issues payment directly to the providers.
3. Regulatory Compliance: The carrier ensures the plan document and summary of benefits meet all state and federal guidelines.
4. Legal Liability: The carrier bears the ultimate legal responsibility for paying covered claims. The employer is removed from the adversarial position of denying an employee’s medical claim.

For an HR department, this creates a clean, predictable workflow. Your team’s responsibility is limited to managing eligibility—adding new hires, removing terminated employees, and remitting the correct premium on the first of each month.

Market Segmentation: Small Group vs. Large Group in Texas

The mechanics of how your fully insured premiums are calculated depend entirely on the size of your business. The Affordable Care Act (ACA) fundamentally severed the group health market into two distinct regulatory environments: the Small Group market and the Large Group market. The dividing line is 50 Full-Time Equivalent (FTE) employees.

Defining the 50 FTE Threshold

Counting your employees is not as simple as checking your payroll headcount. Federal law requires you to calculate Full-Time Equivalents. A full-time employee is defined as anyone working 30 or more hours per week. To count part-time employees, you aggregate all part-time hours worked in a month and divide by 120. Add that number to your full-time headcount.

If your combined FTE total is 50 or fewer, you are a Small Group. If it is 51 or higher, you are a Large Group.

The Small Group Market (1-50 FTEs): Community Rating

If you fall into the small group category, your rates are governed by strict ACA community rating rules. Insurance carriers in Texas are legally prohibited from asking about your employees’ medical history. You cannot be denied coverage, and your rates cannot be increased because one of your employees has a chronic illness.

Instead, premiums in the small group market are determined by exactly three allowable variables:

1. Age: The ACA permits carriers to charge older employees more than younger employees, but the variance is capped at a 3:1 ratio. A 64-year-old employee’s base premium can be no more than three times the cost of a 21-year-old’s premium. Every employee is assigned a specific rate based on their exact age.
2. Geography: Texas is divided into 26 distinct Geographic Rating Areas by the federal government. Healthcare costs in Houston (Harris County) differ from costs in Lubbock, which differ from rural West Texas. Your company’s physical headquarters determines your rating area.
3. Tobacco Use: Carriers can apply a surcharge of up to 50% (a 1.5:1 ratio) for employees who use tobacco, though in practice, many carriers apply a smaller surcharge or waive it if the employee enters a cessation program.

Because these are the only allowable factors, shopping for small group insurance is highly standardized. If you request a quote from a carrier for a specific Gold plan, the rate generated by their algorithm is the exact rate you will pay. There is no room for medical underwriting negotiations.

The Large Group Market (51+ FTEs): Experience Rating

The moment your company crosses into the 51+ FTE tier, the rules change entirely. Large group fully insured plans are not subject to ACA community rating. Instead, they are experience-rated.

Experience rating means the carrier looks at your specific group’s demographic makeup and historical claims data (your “experience”) to project future costs. If you are transitioning into the large group market for the first time, employees will typically be required to fill out medical health questionnaires, or the carrier will utilize aggregate prescription data to assess the risk profile of your team.

In the large group market, health matters. If your workforce is exceptionally young and healthy, your premiums could be significantly lower than the community-rated small group equivalents. If your workforce has multiple severe, ongoing medical conditions, the carrier will load those projected costs directly into your premium. Unlike small group plans, large group rates are highly negotiable. Your broker can challenge the carrier’s underwriter, demand lower administrative fees, and negotiate the final premium based on competitive pressure from other carriers.

Minimum Contribution and Participation Requirements

Health insurance carriers require mandatory contribution and participation minimums to protect themselves against adverse selection. Adverse selection occurs when an employer offers a health plan but contributes very little toward the cost. In that scenario, only the sickest employees—those who desperately need medical care—will choose to pay the high premiums to enroll. Healthy employees will decline the coverage. This leaves the carrier with a risk pool composed entirely of high-cost claimants, leading to severe financial losses.

To prevent this, carriers enforce two strict rules that HR administrators must manage carefully.

The 50% Minimum Contribution Rule

Virtually all carriers require the employer to pay a minimum of 50% of the lowest-cost plan’s employee-only premium.

For example, if the baseline Bronze plan costs $400 per month for a single employee, the employer must contribute at least $200 per month. The employee pays the remaining $200 via payroll deduction.

Crucially, this requirement generally only applies to the employee’s coverage. Employers are not mandated by carriers to contribute to the cost of dependent coverage (spouses or children). An employer can legally contribute 50% to the employee premium and 0% to the dependent premium, leaving the employee to cover the full cost of their family members. However, in the competitive Texas labor market, many employers choose to subsidize a portion of dependent tiers to attract and retain top talent.

The 70-75% Minimum Participation Rule

Carriers also require that a critical mass of your workforce enrolls in the plan. In Texas, the standard requirement is that 70% to 75% of eligible employees must participate.

Understanding how to calculate this percentage is a core competency for any HR professional. The denominator in this equation is not your total headcount. You are allowed to remove employees who have “valid waivers” from the calculation entirely.

A valid waiver is an employee who declines your coverage because they are actively enrolled in another qualified health plan. Valid waivers include:

• Coverage under a spouse’s employer plan
• Coverage under a parent’s plan (if under age 26)
• Medicare
• Medicaid or CHIP
• TRICARE (military coverage)
• Individual ACA marketplace coverage (in some carrier guidelines)

If you have 20 eligible employees, and 5 waive coverage because they are on their spouse’s plans, your net eligible total is 15. To hit a 75% participation requirement, you only need 12 of those remaining 15 employees to enroll.

Special Enrollment Period Exemption: If your company struggles to meet minimum participation requirements, there is a federal loophole. Under the ACA, carriers must offer a Special Enrollment Period (SEP) for employers between November 15 and December 15 each year. During this window, small employers can enroll in a fully insured group plan for a January 1 effective date without being subject to any minimum participation or employer contribution requirements.

State Mandates vs. Federal ERISA Oversight

One of the most legally significant aspects of a fully insured plan is its jurisdictional oversight.

When a large corporation self-funds its health insurance, the plan is governed almost exclusively by federal law under the Employee Retirement Income Security Act (ERISA). ERISA preempts state insurance laws, allowing a self-funded employer to design a uniform plan across all 50 states without worrying about local mandates.

Fully insured plans do not enjoy this preemption. When you buy a fully insured policy in Texas, you are purchasing an insurance product that is heavily regulated by the Texas Department of Insurance (TDI).

This means your plan must strictly adhere to all Texas state-mandated health benefits. The Texas legislature frequently passes laws dictating what insurance carriers must cover. Therefore, your fully insured plan automatically includes coverage for:

• Reconstructive surgery following a mastectomy
• Specific baseline care for autism spectrum disorder
• Telehealth parity (requiring virtual visits to be covered similarly to in-person visits)
• Minimum stays for maternity care
• Temporomandibular joint (TMJ) disorder treatments
• Routine mammography and prostate cancer screenings

For the HR leader, this means plan design is largely out of your hands. You cannot tell the carrier, “We want to exclude coverage for state-mandated autism therapies to save money.” The policy is a pre-packaged product that complies with state law, ensuring a high baseline of comprehensive coverage but limiting your ability to strip out benefits for cost-containment purposes.

Network Architectures in the Texas Market

When selecting a fully insured plan, the defining feature that dictates employee experience is the network structure. Texas is a geographically massive state with highly consolidated hospital systems in major metros like Dallas-Fort Worth, Houston, San Antonio, and Austin. The network you choose determines which doctors your employees can see and how much flexibility they have.

Health Maintenance Organization (HMO)

HMOs are highly restrictive but generally offer the most competitive premiums. In an HMO, employees must select a Primary Care Physician (PCP). The PCP acts as a gatekeeper. If an employee needs to see a specialist—like a dermatologist or an orthopedic surgeon—they must first obtain a referral from their PCP.

Crucially, HMOs in Texas typically offer zero out-of-network benefits, except in life-threatening medical emergencies. If an employee chooses to see a doctor outside the HMO network, they are responsible for 100% of the bill.

Preferred Provider Organization (PPO)

PPOs are the gold standard for employee flexibility, though they carry significantly higher premiums. In a PPO, employees do not need a PCP, and they do not need referrals to see specialists. Furthermore, PPO plans include out-of-network benefits. If an employee sees a physician who is not contracted with the carrier, the plan will still cover a portion of the cost (subject to a separate out-of-network deductible and coinsurance).

For Texas employers with distributed workforces or sales teams that travel out of state, PPOs are often required to ensure employees have access to care regardless of their location.

Exclusive Provider Organization (EPO)

EPOs serve as a modern middle ground. Like a PPO, an EPO does not require a Primary Care Physician or referrals for specialists. Employees can book appointments directly with in-network specialists. However, like an HMO, an EPO offers zero out-of-network benefits. If the provider isn’t in the network, the plan pays nothing.

EPOs are increasingly popular among Texas employers because they remove the administrative friction of referrals while keeping premium costs lower than a full PPO.

Financial Comparisons: Fully Insured vs. Alternative Models

Understanding where a fully insured plan fits into the broader ecosystem of group benefits is critical for making an informed financial decision. HR leaders routinely weigh the fully insured model against Self-Funded, Level-Funded, and Individual Coverage HRA (ICHRA) structures.

Fully Insured vs. Self-Funded

In a self-funded environment, the employer retains their capital. If claims are low, the employer keeps the money. The tradeoff is administrative complexity and cash flow volatility. Self-funding requires hiring a Third-Party Administrator (TPA), purchasing individual and aggregate stop-loss insurance, and managing complex ERISA compliance. The fully insured model trades that potential savings for absolute peace of mind and simplified administration.

Fully Insured vs. ICHRA

The Individual Coverage Health Reimbursement Arrangement (ICHRA) is a fundamentally different approach. Instead of buying a group plan, the employer sets a budget (e.g., $400 per month per employee). Employees take that tax-free money and purchase their own individual health insurance on the ACA marketplace.

Fully insured plans provide a cohesive corporate benefit—everyone is on the same carrier network. ICHRA transfers the choice (and the burden of navigating the individual market) to the employee. For employers who want to offer a robust, traditional recruitment tool, fully insured remains superior. For employers who simply want to cap their healthcare budget and wash their hands of renewals, ICHRA is the emerging alternative.

The Administrative Reality: Day-to-Day HR Operations

Choosing a fully insured plan is only the first step. The day-to-day administration of the plan requires strict adherence to compliance timelines and tax laws.

Pre-Tax Deductions and Section 125 POP

When an employee pays their portion of the fully insured premium, they expect to pay it with pre-tax dollars. However, an employer cannot legally deduct premiums on a pre-tax basis unless they have established a Section 125 Premium Only Plan (POP).

A Section 125 POP is a formal plan document that must be adopted by the company. It allows employees to avoid federal income tax and FICA taxes on their premium contributions, while simultaneously saving the employer the 7.65% matching FICA tax on those amounts. For HR, ensuring the Section 125 document is current and compliant is a critical administrative duty.

Qualifying Life Events (QLEs) and Open Enrollment

Employees cannot join or drop from a fully insured plan whenever they want. They have two windows of opportunity:

1. Annual Open Enrollment: A fixed period once a year where anyone can enroll, drop, or change their coverage.
2. Qualifying Life Events: A 30-day window triggered by specific life changes, such as marriage, divorce, the birth or adoption of a child, or the involuntary loss of other coverage.

HR must police these QLEs strictly. If an employee requests to add their new spouse to the plan, HR must collect the marriage certificate and notify the carrier within 30 days of the event. If HR misses this window, the carrier will reject the enrollment, and the spouse must wait until the next annual open enrollment.

Continuation of Coverage: COBRA vs. Texas State Continuation

When an employee leaves the company, they have the right to continue their health insurance. The governing law depends on the size of your business.

Federal COBRA: If your company had 20 or more FTEs on more than 50% of its typical business days in the previous calendar year, you are subject to federal COBRA. Terminated employees can elect to stay on your fully insured plan for up to 18 months (sometimes up to 29 or 36 months in specific circumstances). The employee must pay 102% of the total premium. The employer is legally required to send complex COBRA election notices within strict federally mandated timeframes—a process almost all HR departments outsource to a Third-Party Administrator.

Texas State Continuation: If your company has fewer than 20 employees, federal COBRA does not apply. Instead, you are governed by Texas State Continuation rules. Under state law, employees who have been continuously enrolled for at least three consecutive months prior to termination can elect to stay on the plan for up to 9 months. They pay 100% of the premium. HR is responsible for notifying the employee of this right upon termination.

Medical Loss Ratio (MLR) Rebates

One unique administrative function of fully insured plans involves the Medical Loss Ratio. Under the ACA, insurance carriers must spend a certain percentage of the premium revenue they collect directly on clinical care and quality improvement. For small groups, carriers must spend 80%. For large groups, they must spend 85%.

If a carrier fails to hit this target—meaning they spent too much on administrative overhead and profits—they are legally required to issue MLR rebate checks back to the employers. If your HR department receives an MLR rebate check, compliance rules dictate exactly how you must handle it. The portion of the rebate corresponding to the employer’s contribution can be kept by the company, but the portion corresponding to the employees’ premium contributions must be distributed back to the employees or used to enhance their benefits.

The Annual Renewal Process and Rate Negotiations

Fully insured contracts run on a 12-month cycle. Approximately 60 to 90 days before your plan’s anniversary date, the carrier will issue your renewal package. This package outlines your new premium rates for the upcoming year.

In the fully insured market, rates almost always go up. This is driven by medical trend—the combination of baseline healthcare inflation (the rising cost of prescription drugs and hospital procedures) and increased utilization.

Negotiating the Renewal

Your ability to negotiate a renewal depends entirely on your market segment.

If you are a Small Group (1-50 FTEs), the renewal rate is non-negotiable. It is generated by the ACA community rating algorithm based on the age of your current workforce. If the rate is unacceptable, your only recourse is to have your broker quote alternative carriers in the Texas market to see if a competitor has a cheaper baseline rate for your demographic area.

If you are a Large Group (51+ FTEs), the renewal is highly negotiable. The carrier’s underwriter calculated your renewal based on your group’s specific claims experience over the past year. Your broker will request the underlying claims data and challenge the underwriter’s assumptions. Brokers routinely negotiate large group renewals down by arguing against excessive administrative loads, challenging the projected cost of large ongoing claims, or leveraging competing quotes from other carriers.

Actionable Decision Matrix: Is Fully Insured Right for You?

Deciding whether to remain fully insured or pivot to an alternative model requires a clear assessment of your company’s risk tolerance, administrative capacity, and size.

• Stay Fully Insured If: You have fewer than 50 employees, you lack the cash reserves to handle sudden financial shocks, and your primary goal is absolute budget predictability. The fully insured model requires the least specialized accounting and completely isolates you from the financial devastation of a catastrophic employee illness.
• Consider Level-Funded If: You have 20 to 100 employees who are demonstrably young and healthy. You are tired of paying high community-rated premiums to subsidize sicker groups, but you still want the fixed-monthly-cost feel of a traditional plan.
• Consider ICHRA If: You are struggling to hit minimum participation requirements, you have widely distinct classes of employees (e.g., salaried corporate vs. hourly field staff), and you want to implement a defined-contribution model where your costs are rigidly capped.
• Consider Self-Funded If: You have more than 200 employees, strong cash flow, and a sophisticated HR team capable of deploying targeted wellness programs and direct primary care models to actively manage claims costs.
