Shopping group health for your team
For enterprise employers in Maryland, transitioning to a self-funded health insurance plan represents a fundamental shift in how employee benefits are financed and administered. Instead of purchasing a fully insured policy where a carrier takes on the financial risk in exchange for a fixed, non-refundable premium, a self-funded employer assumes the claims risk directly. You pay for the healthcare your employees actually consume, utilizing stop-loss insurance to cap catastrophic downside risk. This model trades guaranteed monthly premium predictability for total plan design flexibility, access to granular claims data, and the ability to retain unspent healthcare dollars on your own balance sheet.
To understand self-funding, HR leaders and executives must first deconstruct the fully insured model they are likely leaving behind.
In a traditional fully insured arrangement, the employer pays a set monthly premium per enrolled employee. That premium is a bundled calculation engineered by the insurance carrier. It encompasses the projected cost of medical and pharmacy claims, administrative overhead, premium taxes, risk charges, and the carrier’s profit margin. Once that premium is paid, the money is gone. If your workforce is exceptionally healthy and incurs fewer claims than the carrier projected, the carrier retains the surplus as profit. If your group incurs catastrophic claims that exceed the premium collected, the carrier absorbs the loss—though they will systematically recoup it through drastic premium increases at your next renewal.
Self-funding unbundles this entirely. The employer establishes a legal trust or dedicated reserve account. When an employee visits a physician or fills a prescription, the bill is routed to a Third-Party Administrator (TPA). The TPA adjudicates the claim—meaning they review it against the plan’s rules, apply network discounts, and determine the exact amount owed. Once approved, the TPA signals the employer’s bank account to release the exact funds needed to pay the provider.
Under this architecture, your healthcare budget is broken into three distinct financial components:
If your variable claims come in below projections, the unspent funds remain in the company’s operating capital. The risk—and the reward—belongs strictly to the employer.
A critical decision point for any executive evaluating self-funding is organizational scale. While small groups may experiment with “level-funded” plans (a hybrid model where claims risk is tightly smoothed by fixed monthly payments), pure self-funding requires a risk pool large enough to generate statistical predictability.
Actuarial science relies on the Law of Large Numbers. In a 50-person company, a single premature birth resulting in a $750,000 Neonatal Intensive Care Unit (NICU) stay will completely shatter the healthcare budget, creating unsustainable month-to-month cash flow crises. In a 1,000-person enterprise, that same $750,000 claim represents a smaller, manageable percentage of the total multi-million-dollar claims projection.
Enterprise employers have the sheer volume of members required to dilute individual catastrophic anomalies. While there is no rigid legal minimum for self-funding, organizations with 500 or more employees are generally positioned to safely self-fund. At this scale, the baseline utilization of routine care (pediatric visits, maintenance medications, standard diagnostic imaging) becomes highly predictable, allowing CFOs to forecast cash flow requirements with high accuracy.
Furthermore, scale allows an employer to set higher “attachment points” on their stop-loss insurance, reducing the premium cost of that protection and maximizing the financial efficiency of the self-funded model.
One of the most powerful legal advantages of self-funding is rooted in the Employee Retirement Income Security Act of 1974 (ERISA).
In the fully insured market, health insurance policies are regulated at the state level. In Maryland, this means the Maryland Insurance Administration dictates which benefits a fully insured policy must legally cover. State governments frequently pass legislation requiring carriers to cover specific treatments, which are known as state mandates. Maryland has a robust list of state mandates, encompassing specific requirements for things like fertility preservation, certain behavioral health interventions, and specific medical devices.
While these mandates provide broad consumer protections, they artificially inflate the baseline cost of insurance and create administrative nightmares for enterprise employers operating across state lines. If a fully insured company is headquartered in Maryland but has large operational footprints in Virginia and Delaware, they must purchase state-specific policies or riders that comply with the divergent legislative mandates of all three states. This results in inequitable benefit structures where an employee in one state has a completely different coverage reality than their peer in another state.
ERISA changes the jurisdictional landscape. Under ERISA’s “deemer clause,” a self-funded employee benefit plan is not legally deemed to be an insurance company. Therefore, state insurance laws do not apply.
By self-funding, a Maryland employer completely bypasses the Maryland Insurance Administration. The plan is regulated exclusively at the federal level by the Department of Labor (DOL) and the Internal Revenue Service (IRS). This preemption allows an enterprise to write a single, unified Plan Document. The employer dictates the exact parameters of coverage, ensuring that an employee in Baltimore receives the exact same health benefits as an employee in Richmond. You retain the freedom to voluntarily cover advanced therapies or fertility treatments, but you are not statutorily compelled to do so by local state legislatures.
Note: Self-funded plans must still comply with all federal mandates, including the Affordable Care Act (ACA) preventive care requirements, the Mental Health Parity and Addiction Equity Act (MHPAEA), and the Consolidated Appropriations Act (CAA).
| Feature | Fully Insured Plan | Self-Funded Plan | Enterprise Impact |
|---|---|---|---|
| Claims Risk | Assumed entirely by the carrier. | Assumed by the employer, capped by stop-loss. | Employer retains unspent claims dollars instead of funding carrier profit. |
| Regulatory Jurisdiction | State specific (Maryland Insurance Administration). | Federal only (ERISA, DOL). | Allows unified, consistent benefits across multi-state workforces. |
| Data Access | Minimal to none; aggregate reporting only. | Line-item, granular claims data (de-identified). | Enables aggressive cost-containment and targeted wellness strategies. |
| Premium Taxes | Typically 2-3% of total premium paid to the state. | Only applied to the stop-loss premium portion. | Immediate baseline reduction in fixed administrative overhead. |
Because medical costs possess a virtually limitless ceiling, no prudent employer self-funds without a safety net. That safety net is stop-loss insurance. It is a secondary policy that indemnifies the employer, not the employee, against catastrophic financial exposure.
Stop-loss operates on two distinct axes: Specific (Individual) and Aggregate (Group). Understanding the mechanical interplay between these two layers is the core competency of managing a self-funded risk portfolio.
Specific stop-loss protects the employer from catastrophic claims incurred by a single covered member. The employer works with their actuary and broker to select an “attachment point” (essentially a massive deductible). Common attachment points for enterprise employers range from $100,000 to $500,000, depending on risk tolerance and cash flow scale.
If an employer selects a $150,000 specific attachment point, the employer is solely responsible for paying the first $150,000 in medical and pharmacy claims for any individual employee or dependent within the plan year. If an employee suffers a severe cardiac event generating $800,000 in billed claims, the employer pays the first $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 claims across the entire population. It prevents the employer from being bankrupted by a scenario where no single individual breaches the specific attachment point, but the workforce collectively consumes an unprecedented volume of routine care.
Actuaries calculate an “expected claims” baseline for the year. Aggregate stop-loss is typically set at an attachment point of 125% of those expected claims. For example, if your actuarial expected claims for the year are $10,000,000, your aggregate attachment point would be $12,500,000. The employer pays all claims up to that 125% threshold. If a severe flu season and an unusually high volume of elective surgeries drive the total plan spend to $14,000,000, the aggregate stop-loss policy reimburses the employer for the $1,500,000 overage.
When securing stop-loss coverage, the carrier’s underwriters will meticulously review your group’s historical health data. If they identify an individual who is already actively undergoing catastrophic treatment (e.g., an employee on the transplant list or receiving million-dollar specialty infusions), they will issue a “laser.”
Lasering means the underwriter applies a uniquely higher attachment point to that specific individual, rather than denying the group coverage or raising the premium for everyone. If the standard specific attachment point is $150,000, the underwriter might assign a $750,000 laser to the known high-risk individual. The employer must absorb up to $750,000 for that specific person before stop-loss engages. Managing lasers, negotiating “no-new-laser” renewal contracts, and budgeting for lasered liability is a sophisticated component of enterprise HR finance.
Stop-loss contracts are notoriously complex regarding timing. Medical claims are rarely billed and paid on the exact day the service is rendered. A hospital stay in late December might not be fully processed and paid by the TPA until February of the following year.
Stop-loss policies are defined by two numbers, structured as [Months Incurred] / [Months Paid].
Choosing the correct contract basis prevents devastating coverage gaps during renewals or when transitioning TPA vendors.
In a fully insured model, the insurance carrier performs every function: taking the risk, renting out the physician network, processing the claims, and handling customer service. In a self-funded model, the risk is held by the employer, but the operational execution must be outsourced. Enter the TPA.
The TPA is the operational engine of a self-funded plan. They process enrollment files, adjudicate claims according to the exact rules written in your Plan Document, issue ID cards, provide member call centers, and generate the reporting packages you rely on to manage the plan’s finances.
Employers generally face a structural choice in how they secure TPA services:
Major national insurance carriers offer their own TPAs to large employers. Under an ASO contract, you pay the carrier a per-employee fee to use their proprietary physician network, their internal claims processing systems, and their negotiated provider discounts.
Independent TPAs do not own an insurance brand or a proprietary physician network. Instead, they process claims neutrally and “lease” access to major provider networks on your behalf.
Prescription drugs frequently represent 25% to 35% of an enterprise employer’s total healthcare spend, driven fiercely by the explosion of high-cost specialty medications and injectable biologics. Managing this specific risk requires intense structural discipline.
In a fully insured or bundled ASO environment, the pharmacy benefit is managed by a Pharmacy Benefit Manager (PBM) chosen by the carrier. The employer has no insight into the contract, the drug formularies, or the financial incentives.
Self-funding allows an employer to “carve out” the pharmacy benefit. This means the employer hires an independent TPA to process medical claims, but signs a direct, separate contract with an independent PBM to manage prescription drugs. This strategy reveals two massive financial levers: Pricing Models and Rebate Retention.
Traditional bundled PBMs frequently utilize “spread pricing.” If an employee fills a generic prescription, the pharmacy might charge the PBM $10. The PBM then turns around and bills the employer $45 for that same drug, pocketing the $35 “spread” as hidden profit.
By carving out the pharmacy benefit, a self-funded employer can demand a “pass-through” contract. Under pass-through pricing, if the pharmacy bills the PBM $10, the PBM bills the employer exactly $10. The PBM makes their revenue strictly through a transparent, flat administrative fee per claim, completely eliminating hidden margins.
Pharmaceutical manufacturers pay billions of dollars in rebates to PBMs to ensure their branded drugs receive favorable placement on the PBM’s formulary. In traditional bundled arrangements, the PBM or the carrier keeps the vast majority of these rebate dollars.
A sophisticated self-funded enterprise will negotiate a contract that dictates 100% of pharmaceutical rebates are passed directly back to the employer. For a 1,000-person organization, capturing full rebate retention can result in hundreds of thousands of dollars in hard-dollar returns to the plan’s operating account each year.
Shifting to self-funding fundamentally alters an organization’s balance sheet. CFOs and controllers must institute disciplined accounting mechanisms to manage the liquidity required to pay claims directly.
Because of the lag between when a medical service is rendered and when the TPA actually processes the bill, a self-funded plan operates with a constant tail of unpaid liability. To remain compliant and solvent, the employer must establish an Incurred But Not Reported (IBNR) reserve.
Actuaries will calculate the required IBNR based on your group’s demographic risk and claims velocity. The company must hold this specific amount in cash reserves on the balance sheet. If the company ever decides to terminate the self-funded plan and return to the fully insured market, the IBNR reserve is the money used to pay off the remaining claims from the prior year during the run-out period.
Every state levies a premium tax on fully insured health policies, typically ranging from 2% to 3%. This tax is baked into the fully insured premium. In a self-funded plan, you are not buying insurance for the bulk of your healthcare spend—you are paying claims directly. Therefore, state premium taxes only apply to the stop-loss premium portion of your budget, not the claims portion.
If an enterprise has $15 million in total healthcare costs, removing a 2.5% premium tax from the claims portion yields immediate, compounding six-figure savings with zero change to employee benefits.
To execute daily payments, TPAs require access to employer funds. The most secure and common method is an Imprest or Zero-Balance Account (ZBA). The employer establishes a dedicated bank account for healthcare claims. The TPA issues payments to doctors and hospitals from this account. At the end of each day or week, the bank automatically sweeps exactly the amount of money required to cover those cleared checks from the employer’s master corporate account into the claims account, returning the balance to zero. This ensures the TPA only draws the precise amount needed, preserving the employer’s capital for other corporate uses until the exact moment a claim clears.
Once an enterprise is self-funded and armed with their own data, they possess the structural freedom to implement advanced cost-containment strategies that fully insured carriers typically prohibit.
Hospital billing is notoriously opaque, with massive variance in what different facilities charge for the exact same procedure. In a standard PPO network, the carrier negotiates a percentage discount off the hospital’s billed charge. If a hospital arbitrarily inflates its starting price for an MRI by 400%, a 50% network discount still results in a heavily inflated final bill.
Reference-Based Pricing abandons the traditional PPO network entirely for facility claims. Instead of negotiating down from a hospital’s arbitrary starting price, the self-funded plan pays a flat, transparent multiple of Medicare rates (e.g., 140% of what Medicare would pay for the same service). This enforces strict price rationality. While RBP requires extensive employee education and robust legal defense mechanisms against “balance billing,” it frequently drives the most aggressive cost reductions available to self-funded employers.
With total plan design control, a self-funded employer can analyze their data, identify that musculoskeletal issues are driving 30% of their claims, and build a specialized solution. The employer can legally waive all deductibles and out-of-pocket costs for any employee who agrees to travel to a designated Center of Excellence (a hospital with elite outcome metrics for joint replacement) that the employer has directly contracted with for a bundled, upfront cash price. The hospital gets guaranteed payment, the employee pays nothing out of pocket, and the employer secures a predictable, lower cost for the surgery while avoiding the complications of low-quality local care.
The flexibility of ERISA comes with rigid federal oversight. Executive leadership must understand that under ERISA, they are legally designated as fiduciaries. They are legally bound to manage the health plan strictly in the best financial interest of the plan participants (the employees), not the corporation.
The CAA fundamentally heightened the fiduciary exposure for self-funded plan sponsors. Among other mandates, the CAA requires employers to:
In a fully insured model, the carrier dictates the rules and issues a Certificate of Coverage. In self-funding, the employer is the author of the rules. The employer must draft and distribute a Summary Plan Description (SPD) and a master Plan Document. This document is a binding legal contract. If an employee challenges a denied claim, the federal courts will look exclusively to the precise language written in your Plan Document. Ambiguity in a self-funded Plan Document is almost universally ruled against the employer.
Self-funded employers must execute specific IRS reporting. While fully insured employers file Form 1094-C and 1095-C to prove they offered affordable coverage under the ACA mandate, self-funded employers must complete Part III of Form 1095-C, providing month-by-month enrollment data for every covered individual to prove actual coverage was provided. Additionally, self-funded plans are responsible for calculating and paying the annual Patient-Centered Outcomes Research Institute (PCORI) fee directly to the IRS, a task the carrier typically handles for fully insured groups.
Transitioning to a self-funded arrangement is an enterprise-level project that requires meticulous runway. Attempting to force a transition in under 90 days guarantees catastrophic administrative failures. A standard, responsible transition timeline requires 6 to 9 months of execution.
Phase 1: Feasibility and Analytics (Months 1-3) Your brokerage and actuarial team will gather your historical claims data, demographic profiles, and utilization metrics. They will run predictive modeling to establish your expected claims baseline and stress-test your cash flow against worst-case stop-loss scenarios. If the data proves self-funding is viable, you issue Requests for Proposals (RFPs) to TPAs, PBMs, and stop-loss carriers.
Phase 2: Vendor Selection and Contracting (Months 4-5) Leadership selects the TPA network architecture (ASO vs. Independent) and negotiates the PBM contract, focusing intensely on rebate retention and pass-through pricing. Stop-loss underwriting occurs, requiring executives to complete detailed disclosure statements attesting to any known severe ongoing medical cases within the employee population to finalize the attachment points and laser structure.
Phase 3: Plan Design and Drafting (Month 6) The employer drafts the bespoke Plan Document. This is the moment to execute specific carve-outs, define the parameters of the pharmacy formulary, and legally establish any specialty programs like Centers of Excellence or advanced prior authorization rules.
Phase 4: Implementation and Communication (Months 7-9) The TPA builds the employer’s customized rules engine in their adjudication software. Data feeds are established between the employer’s payroll system, the TPA, and the PBM. The company launches an aggressive employee communication campaign. Because self-funding often involves new ID cards, new pharmacy networks, and new member portals, clear communication is critical to preventing workforce disruption on day one.
Phase 5: Go-Live and Ongoing Auditing The plan launches. Leadership pivots from implementation to active management. Fiduciaries should plan to execute independent, third-party claims audits of their TPA every 12 to 24 months to ensure claims are being adjudicated precisely according to the Plan Document, and that the PBM is honoring the agreed-upon rebate yields.
Review these baseline indicators to determine if your enterprise possesses the structural readiness for a self-funded transition.
For Maryland employers that have achieved the requisite scale, remaining fully insured often means surrendering control, forfeiting data, and financing carrier profit margins with unspent claims dollars. Transitioning to a self-funded architecture is not merely an HR benefit adjustment; it is a profound corporate financial strategy that reclaims authority over one of the largest line items on the corporate ledger.
