The following is a guest post from Michael Paull, president and CFO at The Ahola Corporation. Opinions are the author’s own.

Few workplace changes generate more complaints than a new health plan. New insurance cards, different providers and prescription transfers create friction for employees and their families. Yet for leadership teams, the decision is rarely emotional. Health benefits are often the second-largest expense after payroll, and rising premiums force companies to revisit plan design year after year.

For many CFOs, the health plan is something they inherited rather than something they built. Under a traditional fully insured structure, the mechanics are simple. The company pays a fixed monthly premium and the carrier assumes the claims risk. Renewal becomes a budgeting exercise.

Over the past two decades, employers have sought ways to slow those rising costs. High-deductible health plans encouraged greater consumer responsibility and cost awareness. For many organizations, self-insurance is now the next logical step. Instead of paying a carrier to absorb the risk, the company assumes the claims risk directly in exchange for greater control and potential savings.

But once that decision is made, the real change is not pricing. It is a responsibility.

When you self-insure, you are no longer simply buying insurance. You are operating a health plan, and much of that responsibility shifts to finance.

Cash flow and funding mechanics

The first place the impact hits is cash flow.

Under a self-insured structure, the single predictable premium payment disappears. In its place are multiple cash outflows that finance must forecast, fund and monitor.

Companies typically pay a fixed fee to a third-party administrator for claims adjudication, reporting and plan administration. Stop-loss coverage, which protects the company from catastrophic claims, is often quoted on a per employee per month basis. Beyond those fixed costs, the company funds actual medical and pharmacy claims, often weekly, and those amounts fluctuate significantly.

Additional services, such as wellness programs or ancillary coverage, add further variability.

This creates a more complex and less predictable cash profile. What used to be a flat expense now behaves more like a managed liability.

The administrative workload increases as well. Accounting and HR teams must process multiple vendors, track claims activity and reconcile funding levels. Lower overall healthcare costs must offset these added responsibilities, but achieving that outcome requires active oversight.

Forecasting and reserves

Managing a self-insured plan is not simply about paying invoices. It requires deliberate planning and funding decisions.

One approach is to pre-fund claims based on projected costs, allowing the third-party administrator to draw down those funds as claims are paid. This smooths cash flow and improves predictability. Another approach is to fund claims as they are incurred. While this can conserve cash early in the year, it creates uneven and unpredictable outflows that are difficult to budget.

Claims often start slowly at the beginning of the plan year and increase as deductibles are met. Timing differences between services rendered and claims processed add further lag. Without a funding strategy and adequate reserves, volatility can surprise even well-run organizations.

Finance must evaluate funding frequency alongside working capital needs, seasonality, debt obligations and capital projects. These decisions should be clearly reflected in the income statement and cash flow forecast.

Employee cost sharing and risk

Self-insurance also complicates the traditional cost-sharing model.

Employees typically pay a fixed payroll deduction, while the company absorbs the variable claims risk. If claims exceed expectations, the company cannot retroactively adjust employee contributions. Setting rates too low strains the budget. Setting them too high can hurt employee retention and morale.

Actuarial projections and historical claims data help inform pricing, but uncertainty remains. A small number of high-cost cases can materially affect results. Clear assumptions, conservative forecasts and transparent communication are critical.

At its core, self-insurance is about risk sharing. The company shares catastrophic risk with the stop-loss carrier and day-to-day utilization risk with employees. Aligning incentives and promoting responsible healthcare consumption can create better outcomes for everyone.

Accounting, controls and compliance

Operationally, finance assumes responsibilities that previously sat with the carrier.

Access to detailed claims data improves visibility but creates new compliance obligations. Organizations must safeguard protected health information and ensure appropriate access controls. Formal policies and procedures around HIPAA compliance become essential.

From an accounting standpoint, separating administrative fees from claims funding improves analysis and budgeting. Tracking claims trends throughout the year provides better insight at renewal and supports more accurate forecasting.

Vendor management also becomes more complex. Instead of one monthly premium invoice, there may be multiple invoices for administration, medical claims and pharmacy claims, often arriving weekly. Reconciliation and oversight become ongoing tasks.

Some plans also require collateral deposits with the stop-loss carrier, which affects cash flow. Depending on overall performance, companies may receive dividends tied to pooled results. These items introduce additional accounting considerations.

Moving to a self-insured health plan does not simply change how benefits are paid. It changes the role of finance.

What was once a predictable premium is replaced by variable cash flows, reserve decisions, compliance requirements and ongoing operational oversight. Claims funding, employee cost sharing, data protection, accounting treatment and vendor management shift from the carrier’s responsibility to the company.

In effect, you are no longer just sponsoring a plan. You are operating one. You are managing a healthcare risk pool.

Organizations that approach self-insurance with the same discipline they apply to any other financial commitment often gain better visibility and capture meaningful long-term savings. But those benefits are not automatic. They require active management, strong controls and consistent governance.

Self-insurance is not passive. It requires active management. It is an operating responsibility, and finance owns it.
