Understanding Self-Funding

What Is Self-Funded Health Insurance?

With a self-funded (also called self-insured) health plan, the employer assumes the financial risk for providing health benefits to employees. Instead of paying a fixed premium to an insurance carrier, the employer pays claims directly as they are incurred.

The employer contracts with a third-party administrator (TPA) to handle claims processing, network access, and day-to-day plan administration. A stop-loss insurance policy protects the employer against catastrophic individual claims and unexpectedly high total claims for the group.

The core components of a self-funded arrangement are:

The fundamental advantage is control. The employer owns the claims data, designs the benefit structure, and retains savings from favorable claims experience rather than subsidizing other groups in a carrier's risk pool.

Why Self-Fund

Key Advantages of Self-Funded Plans

Self-funding is not for every employer, but for organizations with the right size and risk tolerance, the advantages are significant.

Cost Savings

Self-funded plans are exempt from state premium taxes (2-3% in Texas) and ACA community rating requirements. When claims are favorable, the employer keeps the savings — they do not subsidize other groups in a shared risk pool.

Complete Claims Data

Self-funded employers receive detailed monthly claims reports showing exactly where every dollar goes. This data powers smarter decisions about plan design, wellness programs, and provider negotiations.

Plan Design Flexibility

No off-the-shelf plan restrictions. Design custom copay structures, implement reference-based pricing, create tiered networks, and build wellness incentives tailored to your workforce.

ERISA Preemption

Self-funded plans are regulated at the federal level under ERISA, exempting them from state-mandated benefits and state insurance department oversight. This creates a uniform plan across multi-state workforces.

Cash Flow Optimization

Pay claims as they occur rather than pre-paying a carrier with fixed premiums. In low-utilization months, your cash stays in your business. Many employers fund claims from operating cash flow or a dedicated claims account.

Vendor Independence

Separate your TPA, stop-loss carrier, pharmacy benefit manager, and network provider. If one vendor underperforms, replace them without overhauling the entire plan. You are not locked into a single carrier's ecosystem.

Plan Architecture

The Building Blocks of a Self-Funded Plan

A self-funded plan is not a single product — it is an assembly of vendors and contracts that Buffer coordinates on your behalf.

1

Third-Party Administrator (TPA)

The TPA processes claims, manages the provider network, handles member ID cards, and runs customer service. Buffer evaluates TPAs on claims accuracy, turnaround time, reporting quality, and cost.

2

Stop-Loss Carrier

Provides specific (individual) and aggregate (group) stop-loss coverage. Attachment points, contract terms, and laser provisions are negotiated annually. This is the most important contract in the arrangement.

3

Provider Network

PPO, EPO, or custom network access is selected based on your workforce geography and provider preferences. Network discounts are the first line of cost containment — they determine what you pay for every claim.

4

Pharmacy Benefit Manager (PBM)

Manages the prescription drug formulary, negotiates rebates, and controls specialty drug costs. Pharmacy often represents 25-30% of total plan spend — PBM selection and oversight is critical.

5

Claims Funding Vehicle

A dedicated bank account used to fund claims as they are processed. Buffer helps you model expected monthly claims funding levels and establish reserve targets to maintain cash flow stability.

6

Compliance & Reporting

ERISA wrap documents, Summary Plan Descriptions, Form 5500 filings, COBRA administration, and ACA reporting (1094-C/1095-C). Buffer coordinates all compliance requirements across vendors.

Is It Right for You?

Self-Funding: Advantages and Considerations

Self-funding is not a one-size-fits-all solution. Here is an honest look at the advantages and the factors that require careful evaluation.

Advantages
  • Retain savings from favorable claims experience — no carrier profit margin on your premiums
  • Eliminate state premium taxes (2-3% savings in Texas)
  • Full access to claims data for informed decision-making
  • Custom plan design without carrier restrictions
  • ERISA preemption creates uniform benefits across multiple states
  • Separate vendors — replace underperformers without changing the entire plan
  • Cash flow flexibility — pay claims as incurred, not as fixed monthly premiums
Considerations
  • Monthly costs fluctuate based on actual claims — requires cash flow management
  • Higher administrative complexity — multiple vendor relationships to manage
  • ERISA fiduciary responsibility falls on the employer
  • Stop-loss premiums may increase significantly after a bad claims year
  • Smaller groups (under 100) may not have enough claims volume for stable projections
  • Requires active management — a hands-off approach erodes the cost advantage
  • Annual stop-loss marketing and negotiation is essential to maintain competitive rates
Our Process

How Buffer Manages Self-Funded Plans

Self-funded plans require active, year-round management to deliver on their cost advantage. Buffer handles the strategy, vendor coordination, and analytics so your HR team can focus on your people.

1

Feasibility Analysis

We analyze 3+ years of claims data, model expected costs under self-funding, project stop-loss premiums, and compare total cost against your current fully-insured or level-funded arrangement.

2

Vendor Selection

We market your plan to multiple TPAs, stop-loss carriers, PBMs, and network providers. Each vendor is evaluated on cost, service quality, reporting capabilities, and contract terms.

3

Plan Design

We design the benefit structure — copays, deductibles, out-of-pocket maximums, formulary tiers, and wellness incentives — based on your workforce demographics and budget targets.

4

Implementation

We coordinate the transition across all vendors, manage employee communications and enrollment, and ensure the effective date goes smoothly with zero coverage gaps.

5

Monthly Claims Analysis

We review monthly claims reports to identify cost trends, high-cost claimants approaching stop-loss thresholds, utilization patterns, and pharmacy spend drivers before they become problems.

6

Annual Renewal & Re-Marketing

We begin the stop-loss and vendor renewal process 120 days before your plan year ends. Every contract is re-marketed to ensure you are getting competitive rates and terms.

Side-by-Side

Self-Funded vs. Level-Funded vs. Fully-Insured

Each funding model serves a different employer profile. The right choice depends on group size, risk tolerance, cash flow, and how much control you want over plan design.

Feature Fully-Insured Level-Funded Self-Funded
Monthly Cost Fixed premium Fixed payment Variable (claims-based)
Risk Carrier bears all Shared (stop-loss) Employer bears most (stop-loss cap)
Savings Potential None — carrier keeps surplus Surplus refund Maximum — employer retains all savings
Claims Data None Full Full + granular reporting
Plan Design Control Carrier-defined Moderate Complete — custom benefit design
Best Group Size 2 – 50 employees 25 – 300 employees 100+ employees
State Premium Tax Yes (2–3%) Often exempt Exempt
Vendor Flexibility Single carrier Single carrier Separate TPA, stop-loss, PBM, network
Admin Complexity Low Moderate High — active management required
Common Questions

Self-Funded Insurance FAQ

Straightforward answers to the questions CFOs, HR leaders, and business owners ask most about self-funded health insurance.

What is the minimum group size for self-funded insurance?
There is no legal minimum, but self-funded plans work best for employers with 100 or more enrolled employees. At that size, the group has enough claims volume for actuaries to project costs reliably, and the per-employee cost of stop-loss insurance and administration becomes more efficient. Employers with 50 to 100 employees may also self-fund but should evaluate level-funded plans as an alternative that provides similar benefits with less administrative complexity.
How is self-funded different from level-funded?
Both models put the employer in the risk-bearing position with stop-loss protection. The key difference is cash flow structure. With level-funded plans, you pay a fixed monthly amount regardless of actual claims — any surplus is returned later. With self-funded plans, you pay claims as they are incurred, meaning monthly costs fluctuate based on actual utilization. Self-funded plans offer more flexibility in plan design and typically lower total cost for large, stable groups, but require more administrative infrastructure and cash flow management.
What is stop-loss insurance and do I need it?
Stop-loss insurance protects self-funded employers from catastrophic claims. Specific stop-loss covers any single individual whose claims exceed a set threshold — typically $50,000 to $250,000 depending on group size. Aggregate stop-loss caps total group claims for the plan year, usually at 120-125% of expected claims. While stop-loss is technically optional, virtually all self-funded employers carry it. A single catastrophic claim — a premature birth, organ transplant, or cancer treatment — can easily exceed $1 million. Buffer structures stop-loss to balance premium cost against risk exposure.
What kind of claims data will I receive?
Self-funded employers receive detailed monthly and quarterly claims reports that fully-insured groups never see. These include total paid claims by category (inpatient, outpatient, pharmacy, specialty), large claimant reports showing high-cost individuals trending toward stop-loss thresholds, utilization metrics such as ER visits per 1,000 members, generic vs. brand prescription ratios, and preventive care compliance, plus trend analysis showing year-over-year cost changes by service category. This data is invaluable for designing targeted wellness programs, adjusting plan design, and negotiating with providers.
Are self-funded plans subject to state insurance regulations?
No. Self-funded plans are governed by the federal Employee Retirement Income Security Act (ERISA), which preempts state insurance regulation. This means self-funded plans are exempt from state premium taxes (typically 2-3% in Texas), state-mandated benefit requirements, and state insurance department oversight. However, self-funded plans must still comply with federal requirements including ERISA fiduciary duties, HIPAA privacy and portability rules, COBRA continuation coverage, the ACA employer mandate and reporting, and Mental Health Parity and Addiction Equity Act requirements.
How does Buffer help manage a self-funded plan?
Buffer acts as the strategic advisor between you, your TPA, your stop-loss carrier, and your network provider. We analyze claims data monthly to identify cost trends before they escalate, negotiate stop-loss renewals and attachment points, evaluate TPA performance and network adequacy, coordinate pharmacy benefit management strategies, manage compliance obligations including ERISA wrap documents and Form 5500 filings, and run the full renewal and re-marketing process annually. We do not disappear after implementation — active plan management is where the real value of self-funding is realized.
What happens if we have a bad claims year?
A bad claims year is exactly why stop-loss insurance exists. If individual claims exceed your specific stop-loss threshold, the stop-loss carrier reimburses you. If total group claims exceed the aggregate corridor, aggregate stop-loss kicks in. Your maximum exposure is defined by your stop-loss contract — it is not unlimited. After a high-claims year, your stop-loss renewal rates will likely increase, and Buffer works to mitigate that by shopping the stop-loss market across multiple carriers, adjusting attachment points, and implementing clinical management programs to address the underlying cost drivers.
Can I customize plan design with a self-funded plan?
Yes — this is one of the primary advantages of self-funding. Because your plan is not a standardized insurance product, you have full control over benefit design. You can create custom copay and deductible structures, implement reference-based pricing for certain procedures, design tiered networks that incentivize high-value providers, add or remove specific benefits based on workforce needs, build in wellness incentives and health savings account contributions, and create different plan tiers for different employee populations. Buffer helps you design plans that balance employee satisfaction with cost management.
