Shopping group health for your team
For Virginia enterprise employers, transitioning to a self-funded health plan is the structural shift from buying an insurance product to financing healthcare. In a fully insured arrangement, you pay a fixed premium to a carrier, transferring all claims risk and conceding all control over plan design, pharmacy contracting, and data visibility. If your workforce is healthier than average, the carrier keeps the margin. Under a self-funded (or self-insured) model, the employer bears the claims risk directly. You pay for the actual healthcare your employees consume, plus administrative fees and stop-loss insurance to cap catastrophic risk. When claims are lower than projected, those dollars remain in your corporate treasury.
This guide provides a definitive, operational blueprint of self-funding for large employers, HR leaders, and CFOs. We will deconstruct the financial mechanisms, the regulatory advantages of ERISA, the complexities of stop-loss contracting, and the strategic unbundling of third-party administrators (TPAs) and pharmacy benefit managers (PBMs). This is not an introductory overview of group benefits; this is a precise examination of how enterprise organizations execute risk-bearing healthcare models.
To understand whether self-funding is a viable strategy for your organization, you must first unbundle the cash flow. In a fully insured plan, a single monthly premium covers administration, carrier profit, risk charges, premium taxes, and actual claims. In a self-funded plan, the employer physically separates these cost silos, paying for fixed administrative services on a predictable schedule while funding claims as they are incurred.
The cost structure of a self-funded plan operates on three distinct tracks:
1. Fixed Administrative Costs These are the highly predictable, contractual expenses required to operate the plan. They typically represent 15% to 25% of total plan costs. Fixed costs include the per-employee-per-month (PEPM) fees paid to a Third-Party Administrator (TPA) for processing claims, producing ID cards, and managing customer service. It also includes network access fees (the cost to “rent” a provider network like Anthem or Sentara), broker or consultant compensation, and compliance filing fees. These costs remain static regardless of how much healthcare your population consumes.
2. Stop-Loss Insurance Premiums Because a single premature birth, complex cancer diagnosis, or multi-trauma accident can cost millions of dollars, no prudent employer assumes unlimited liability. Stop-loss insurance is the financial backstop that protects the corporate balance sheet. The premiums paid to a stop-loss carrier are a fixed monthly cost, securing protection against catastrophic individual claims (Specific Stop-Loss) and unexpectedly high overall population utilization (Aggregate Stop-Loss).
3. Variable Claims Expenses This is the core of the self-funded model and typically represents 75% to 80% of total plan costs. The employer sets up a designated claims trust or operating account. When an employee visits a doctor, the provider bills the TPA. The TPA adjudicates the claim, applies the network discount, and draws the exact required amount from the employer’s claims account to pay the provider. If it is a heavy claims month—perhaps a cluster of elective surgeries in December—cash flow demands are higher. If it is a light claims month, the cash remains with the employer.
The primary financial argument for self-funding is the elimination of carrier risk margins and the retention of cash flow. Insurance carriers price fully insured premiums to ensure they remain profitable even in adverse scenarios. They calculate expected claims, add a margin for error, add their administrative costs, add premium taxes (which self-funded plans do not pay), and add their profit margin.
If an enterprise employer with 800 employees pays $8 million in fully insured premiums, and the population only incurs $6 million in claims, the carrier retains the $2 million surplus as profit. In a self-funded environment, that $2 million stays in the employer’s bank account, earning interest and improving working capital.
Furthermore, self-funded employers only fund claims as they clear the bank. In a fully insured model, premiums are paid upfront at the beginning of the month. In a self-funded model, the employer holds the cash until the TPA issues the check or electronic funds transfer to the provider—creating a continuous, natural delay in cash outflow that mathematically improves corporate liquidity.
One of the most potent advantages of self-funding is regulatory freedom. In the United States, health insurance is regulated at the state level by entities like the Virginia State Corporation Commission (SCC) Bureau of Insurance. Fully insured plans must comply with every coverage mandate, tax, and regulatory quirk enacted by the state legislature.
Self-funded plans are completely different. Under the federal Employee Retirement Income Security Act of 1974 (ERISA), self-funded health plans are exempt from state insurance laws. This legal doctrine, known as “ERISA preemption,” allows employers to operate their health plans under federal jurisdiction (specifically, the Department of Labor) rather than state jurisdiction.
For enterprise organizations with employees spread across Virginia, Maryland, North Carolina, and beyond, ERISA preemption is critical. If you operate a fully insured plan, you are subjected to a patchwork of state laws. A fully insured contract sitused in Virginia must comply with Virginia mandates, but if you have localized policies for regional offices, you face a compliance nightmare of differing state rules.
A self-funded, ERISA-governed plan allows a corporate HR team to design a single, uniform benefit structure for all employees, regardless of where they live. The benefits offered to a software engineer in Richmond are identical to those offered to a sales director in Austin.
Most states, including Virginia, levy a premium tax on fully insured health insurance policies—typically ranging from 1.5% to 2.5% of the total premium. Because a self-funded plan is not technically an “insurance policy” (it is an employer-sponsored benefit plan financing its own risks), it is entirely exempt from state premium taxes. For a company spending $10 million a year on healthcare, bypassing a 2% premium tax yields an immediate bottom-line savings of $200,000 annually without altering a single clinical benefit.
Because self-funded plans are not subject to state mandates, the employer has total authority over what the plan does and does not cover (subject to federal ACA requirements). If Virginia passes a law mandating that fully insured plans cover a specific, highly expensive alternative therapy, a self-funded employer is not forced to adopt it. Conversely, if an employer wishes to cover a progressive treatment, travel benefit, or specialized center-of-excellence program that is not standard in a carrier’s fully insured filed product, they have the absolute legal authority to write that coverage into their Summary Plan Description (SPD).

The defining factor that allows a business to self-fund without risking bankruptcy is stop-loss insurance. This is not health insurance for employees; it is a financial indemnification policy that reimburses the employer when claims exceed a predetermined threshold. Negotiating and structuring stop-loss correctly is the single most critical task a CFO and benefits consultant will perform in a self-funded arrangement.
Specific stop-loss protects the employer against catastrophic claims incurred by a single individual (an employee or their dependent). The employer selects an “attachment point” or deductible. Common attachment points for enterprise employers range from $100,000 to $500,000, depending on risk tolerance and company size.
If an employer selects a $150,000 specific attachment point, the employer pays the first $150,000 of claims for any individual member during the plan year. If a member undergoes a complex organ transplant resulting in $800,000 in medical bills, the employer’s liability caps at $150,000. The stop-loss carrier reimburses the employer for the remaining $650,000.
While specific stop-loss protects against the severity of individual claims, aggregate stop-loss protects against the frequency of smaller claims. It caps the total financial exposure for the entire population over the plan year.
The stop-loss underwriter calculates the “expected claims” for the group based on historical data and demographics. The aggregate attachment point is typically set at 125% of expected claims. If an employer’s expected claims are $4 million, the aggregate attachment point is $5 million. If the employer experiences an unusually high volume of mid-tier claims (e.g., knee surgeries, ER visits, specialized pharmacy fills) pushing total plan costs to $5.5 million, the aggregate stop-loss policy reimburses the employer for the $500,000 that exceeded the attachment point.
Stop-loss policies are highly precise financial instruments defined by when a medical claim is incurred (the date of service) and when it is paid (the date the TPA issues the check). The gap between a doctor visit and the final payment can be weeks or months. This is known as claims lag or run-out.
When executing a stop-loss contract, employers must choose the contract basis, denoted by a fraction:
A laser is a mechanism stop-loss underwriters use to isolate known risks. If an employer’s workforce includes a dependent with a severe, ongoing condition (e.g., severe hemophilia or late-stage renal failure), the underwriter knows a massive claim is guaranteed next year.
Instead of raising the stop-loss premium for the entire group to an unaffordable level, the underwriter will “laser” the individual. They will assign a separate, much higher specific deductible to that one person. If the group’s specific stop-loss is $100,000, the lasered individual might be given a $750,000 specific deductible. The employer is now directly on the hook for the first $750,000 of that individual’s care. Managing laser liability, negotiating “no-laser” renewal guarantees, and properly reserving capital to fund lasered members is a critical component of self-funded financial strategy.
Because the employer is the insurer in a self-funded plan, they must hire entities to perform the operational mechanics of insurance: adjudicating claims, answering member phone calls, issuing ID cards, and securing provider discounts. There are two primary avenues for executing this: an Administrative Services Only (ASO) arrangement or an Independent Third-Party Administrator (TPA).
An ASO is an arrangement where the employer hires a traditional, major commercial insurance carrier (such as Anthem HealthKeepers, Sentara Health Plans, or Cigna) to administer their self-funded plan.
To the employee, an ASO plan looks identical to a fully insured plan. The member carries an Anthem or Sentara ID card, uses that carrier’s national or regional provider network, and calls that carrier’s customer service line. The only difference happens behind the scenes: when the carrier processes the claim, they withdraw the funds from the employer’s bank account rather than paying it out of their own reserves.
Pros of an ASO:
Cons of an ASO:
An independent TPA is a standalone processing firm that does not own a provider network. Instead, the TPA “rents” a network on the employer’s behalf. An employer might hire an independent TPA based in Virginia, and that TPA will secure a contract to use a national network (like the Cigna OAP or Aetna Signature network) for provider access.
Pros of an Independent TPA:
Cons of an Independent TPA:
In enterprise healthcare, pharmacy costs represent the fastest-growing segment of the budget, routinely comprising 25% to 35% of total plan spend, driven relentlessly by specialty medications (e.g., GLP-1s, biologics, immunology drugs). In a self-funded environment, how you manage pharmacy determines the financial viability of the plan.
If an employer chooses a bundled ASO, the medical carrier forces the employer to use their integrated PBM. If an employer uses an independent TPA, they can “carve out” pharmacy—firing the bundled PBM and hiring a completely independent pharmacy manager. This unbundling is where millions of dollars in enterprise savings are located.
The traditional PBM revenue model relies heavily on “spread pricing.” In this model, the PBM negotiates a discounted price with the pharmacy for a drug, but bills the self-funded employer a higher, different amount, keeping the “spread” as opaque profit. For example, an employee fills a generic prescription. The PBM reimburses the pharmacy $12. However, the PBM bills the employer’s claims account $45 for that exact same transaction. The $33 spread is retained by the PBM. In a population of 1,000 employees filling thousands of scripts a year, spread pricing drains massive amounts of capital from the employer.
By carving out pharmacy, enterprise employers can demand a “Pass-Through” or “Transparent” PBM contract. In a pass-through model, if the PBM pays the pharmacy $12, they bill the employer exactly $12. The PBM earns its revenue entirely through a flat, explicitly stated administrative fee (e.g., $4 per claim). This alignment of incentives ensures the PBM is managing costs, not profiting from arbitrary markup.
Pharmaceutical manufacturers pay massive rebates to PBMs in exchange for placing their high-cost brand-name drugs on the plan’s formulary. In traditional, opaque contracts, the PBM keeps a significant percentage (or all) of those rebate dollars. In a properly negotiated, self-funded transparent contract, the employer demands 100% pass-through of all manufacturer rebates, returning those funds directly to the plan’s operating account.
Furthermore, independent PBMs allow employers to heavily audit Maximum Allowable Cost (MAC) lists—the pricing benchmarks used for generic drugs. Aggressive management of the MAC list and strict specialty drug prior-authorization protocols are mandatory requirements for any enterprise self-funding strategy.
Self-funding is not merely a financial strategy; it is a legal liability shift. By executing a self-funded plan under ERISA, the company’s executives (specifically the plan sponsor, which is usually the corporate entity, HR director, or CFO) assume formal fiduciary duties. You are legally managing plan assets on behalf of the employees.
Historically, employers treated this fiduciary duty lightly, deferring entirely to their insurance carriers. The Consolidated Appropriations Act (CAA) of 2021 aggressively changed this landscape, putting immense compliance pressure directly on self-funded employers.
Under the CAA, self-funded employers must ensure they are paying reasonable fees for services and protecting the plan’s assets. Executives can no longer simply sign an ASO contract and assume the carrier is securing the best discounts. If a TPA or PBM is extracting hidden fees or spread pricing, the employer can be sued by the Department of Labor or the employees for a breach of fiduciary duty, as they allowed plan assets to be wasted.
The CAA strictly prohibits “gag clauses” in contracts between a self-funded employer and a TPA/network. Historically, carrier contracts prevented employers from seeing specific provider reimbursement rates, claiming they were proprietary trade secrets. The CAA outlaws this. Self-funded employers must have full access to their own data to ensure they are getting a fair deal. Enterprise HR teams must now submit a Gag Clause Prohibition Compliance Attestation (GCPCA) to the federal government annually, verifying that their vendor contracts do not restrict data access.
Self-funded plans must file a Form 5500 annually with the Department of Labor, detailing the plan’s financial condition, investments, and operations. Additionally, self-funded employers must independently calculate and pay the Patient-Centered Outcomes Research Institute (PCORI) fee, which is based on the average number of lives covered under the plan. In a fully insured plan, the carrier handles the PCORI fee; in a self-funded plan, the employer is directly responsible for filing IRS Form 720 and remitting the payment.
The ultimate advantage of a self-funded plan is that the employer owns their raw, unredacted claims data. You no longer receive a generic annual report stating “costs went up 8%.” You receive a data warehouse showing exactly which facilities are overcharging for MRIs, which specialty drugs are driving trend, and what chronic conditions are emerging in the workforce.
Armed with this data, Virginia enterprises can implement aggressive, targeted cost-containment strategies that are impossible in fully insured models:
Direct Primary Care (DPC): Self-funded employers can contract directly with DPC clinics in Virginia, paying a flat monthly fee for employees to access unlimited primary care with zero copays. This bypasses the traditional fee-for-service system, removing barriers to preventive care, catching chronic conditions early, and drastically reducing unnecessary ER visits, which the employer would otherwise have to fund fully.
Centers of Excellence (COE) and Steerage: If the data shows that orthopedic surgeries are a major cost driver, the employer can implement a COE program. The self-funded plan can mandate (or heavily incentivize with $0 cost-sharing) that employees needing joint replacements travel to a specific, high-quality, highly-rated facility where the TPA has negotiated a bundled, fixed-rate case price. The employer pays for the employee’s travel, lodging, and surgery in cash, avoiding the massive variable billing of a standard hospital system.
Reference-Based Pricing (RBP): For highly aggressive employers, RBP removes traditional PPO networks entirely. Instead of paying a “discount off billed charges” (which is meaningless if the hospital bills a grossly inflated starting number), an RBP plan pays providers a fair, defined markup over Medicare rates—typically 140% to 160% of what Medicare would pay. While RBP requires intense employee education and aggressive defense against balance billing, it can slash medical spend by 20% to 30% instantly.
Moving an enterprise from fully insured to self-funded is a massive logistical undertaking. It cannot be rushed, and attempting to force a transition in 90 days guarantees catastrophic administrative failures. A standard, responsible transition timeline for a January 1 effective date requires 6 to 8 months of runway.
Self-funding requires specialized accounting for claims that are incurred but not reported (IBNR). Because there is a lag between a doctor’s visit and the claim being paid, an employer is always carrying a liability for services already rendered but not yet billed.
If an enterprise decides to abandon self-funding and return to a fully insured market, they face “terminal liability.” On midnight of December 31st, the self-funded plan terminates. On January 1st, the fully insured plan begins, and the employer starts paying fixed premiums to the new carrier.
However, providers will continue billing the old self-funded TPA for services rendered in November and December. The employer must keep the self-funded claims account open and adequately funded for roughly 3 to 6 months to pay off this run-out. Failure to reserve properly for IBNR terminal liability can cause a massive cash flow crunch, forcing a company to simultaneously pay fully insured premiums and self-funded run-out claims.

For Virginia enterprises with the scale and discipline to manage the mechanics, self-funding is the only structural path out of the perpetual cycle of fully insured rate increases. By unwinding carrier margins, reclaiming data ownership, and asserting fiduciary control over plan assets, an enterprise transforms healthcare from a passive, unmanageable tax into a strategic, actively managed financial lever.
