Fully insured is not simpler — it's just someone else's profit center

Every fully-insured premium dollar contains a carrier margin, a risk charge, and a retention load the employer paid whether or not the claims justified it — and the renewal window is the one moment to see that math clearly.

Most CFOs think of their fully-insured health plan as the low-drama option. Pay the premium, the carrier handles everything, nobody has to think about claims. That framing is not an accident. It is, more or less, the product the carrier is selling — and the margin on that product is embedded in every dollar you wire them before a single employee sees a doctor. No source article is available this week, so we are working from first principles, but the arithmetic is not complicated: a fully-insured premium contains the expected claims cost, an administrative load, a risk charge for the carrier holding that uncertainty, and a profit margin. The employer pays all four components. The employer sees the total. The employer almost never sees the breakdown.

The thing you are actually buying

When a fully-insured employer renews, they are purchasing risk transfer. The carrier is saying: give us a fixed premium and we will absorb whatever the claims turn out to be. That is a real service. The question a CFO should ask — and almost never gets the data to answer — is whether the price of that transfer reflects the employer's actual claims history, or whether it reflects the carrier's need to protect margin across a much larger book of business. These are not the same number, and for a stable, mid-size employer with several years of predictable utilization, the gap between them can be substantial. In comparable plans, we have seen premium reductions averaging around 20% when employers move from a fully-insured structure to a plan design that prices risk more honestly. That is not a rounding error on a budget line.

Why 'simplicity' is a feature the carrier sells

The fully-insured arrangement is genuinely simple for the employer — no claims data to manage, no stop-loss to buy, no monthly settlement. But simplicity has a cost, and that cost is opacity. When you do not see the claims data, you cannot tell whether last year's renewal increase was driven by your employees' actual utilization or by the carrier repricing risk across a segment of their book. You are, in effect, paying for a service and waiving your right to the invoice. A self-funded employer with the same workforce and the same carrier network sees that invoice every month. The fully-insured employer sees a renewal letter.

What the renewal window actually is

The renewal letter is not an invoice. It is a take-it-or-leave-it price for another year of the same arrangement. Most employers treat it as a negotiation over percentage points. It is actually something more consequential: it is the one annual moment when the structural question — are we paying for risk transfer we need, at a price our own claims history would justify — is briefly on the table before it gets locked away for another twelve months. Once you sign, the data disappears back into the carrier's systems and the question becomes academic until the next renewal cycle.

The fix does not require a new carrier

This is the part that surprises most finance teams. The structural change that reprices the risk transfer does not mean switching carriers, renegotiating networks, or asking employees to find new in-network physicians. The same carrier, the same network, the same ID cards — paired with a zero-deductible plan design that changes how the risk is held and priced. Employees generally find it better than what they had. The CFO finds a materially different line item. The carrier relationship stays intact.

What we would tell a client this week: If your renewal window is open — or opening in the next ninety days — do not let the first conversation be a carrier quote. Ask for a structural analysis: what does your actual claims history suggest about the risk transfer you are currently paying for, and is there a plan design that prices that transfer honestly while keeping your current carrier in place? That is a different question than 'can we get a better rate,' and it tends to produce a different answer.
