Large deductible workers' comp programs: how they work and what they cost

A large deductible workers' compensation program is a guaranteed-cost-style policy with a big twist: the insurer pays every claim from the first dollar, then bills you back for the part that falls inside a per-claim deductible, commonly $100,000 or more. You get a lower premium because you are carrying the first layer of loss, and you give the insurer collateral so it is not left holding the bag if you cannot reimburse it. It suits employers with enough premium, enough claims history and enough balance sheet to carry volatility, and it is the usual step between a conventional policy and full self-insuring workers' comp: requirements and trade-offs.

How the money moves

A large deductible program is written on an ordinary workers' comp policy (the standard form is NCCI WC 00 00 00) with a deductible endorsement. The employer's injured workers see no difference. Benefits are paid by the insurer, or by a third-party administrator working under the insurer's authority, and the state's workers' comp agency treats the insurer as the party on the risk.

Behind that, the cycle looks like this:

1. A claim is reported and the insurer or its claims administrator sets it up as if no deductible existed.
2. The insurer pays medical bills and wage benefits as they come due.
3. Periodically, on the schedule the endorsement sets, the insurer invoices you for the paid losses inside the deductible, plus any allocated expenses the endorsement says are included.
4. You reimburse within the period the endorsement sets. If you do not, the insurer draws on collateral.
5. When a claim passes the deductible, the insurer carries the rest. Your reimbursement stops at the per-claim limit and, if the program has one, an annual aggregate.

That sequence is what separates this from a plain deductible on a property policy and from a self-insured retention in liability. In comp, the employer's obligation to the injured worker is statutory and cannot depend on whether the employer pays its bill. Florida's rule for large deductible filings, Rule 69O-189.006, says it directly: the insurer must pay first-dollar loss like any other comp policy without a deductible, and the insured's reimbursement does not reduce the insurer's obligation. deductibles vs self-insured retentions: who pays first covers the contrast with liability retentions.

What counts as "large"

There is no single national definition. In Florida, a filing qualifies only with at least $500,000 of standard premium and a deductible of at least $100,000 (Rule 69O-189.006). Other states use different lines: Nevada's reporting rule, as described in an NCCI circular reported by WorkCompCentral in June 2018, applies to policies where the policyholder is liable for at least $25,000 per claim. Many carriers set their own floors for the program based on premium size and credit quality.

Small deductible plans, often $500 to $10,000 or so, are a different product. They are usually filed through the rating bureau's manual and the insurer collects the deductible from the employer, but there is no collateral to speak of. Large deductible programs are typically filed by each carrier with the state rather than through the standard NCCI deductible rules, so the rating credit, the loss development factors and the collateral terms are negotiated, not looked up in a table. Ask your broker which filing governs your program and read it.

Collateral: the part buyers underestimate

Because the insurer is on the hook for losses you owe back, it wants security for the deductible layer. Collateral is usually one of three things:

• An irrevocable letter of credit from a bank, which ties up borrowing capacity under your credit line.
• A surety bond from an unaffiliated surety (see surety bond), which costs a fee but does not draw on your credit line the same way.
• Cash or a trust account, the most expensive form because the money earns less than it could in your business.

The amount is not just the deductible. Insurers set collateral against expected unpaid losses in the layer, including development on old claims, and ask for more at each renewal until older years close out. A long-tail comp claim can stay open for decades, so collateral on a program you left five years ago can still be sitting there. Negotiating the release schedule, and who audits it, matters as much as the premium credit.

The NAIC and the National Conference of Insurance Guaranty Funds have both published guidance on large deductible programs because insolvencies exposed weak collateral and commingled funds in some PEO-related failures. For a buyer the lesson is practical: confirm the collateral is held separately, in an account or instrument the insurer cannot use for anything else.

Premium, taxes and your experience mod

The premium on a large deductible policy is built differently from the ordinary guaranteed-cost premium. The insurer starts with the standard premium and credits the expected losses in the deductible layer, then adds charges for claims handling, excess loss, taxes and assessments, and profit. Two items surprise first-time buyers.

• Taxes and assessments often track the full pre-deductible premium. Workers' comp assessments and premium taxes in many states are based on what the premium would have been without the deductible, so the savings are smaller than the credit suggests. Ask the broker for the program quote shown both ways.
• Your mod keeps working. Under Florida's rule, the insurer must report all losses, including those below the deductible, through unit statistical reporting so an experience modification factor can be calculated. Your losses still feed your experience modification rate, and the mod still matters for contract bids and for any other states where you buy conventional coverage. See The experience modification rate (EMR) explained.

Worked example (hypothetical)

Say a 400-employee manufacturer in a competitive-market state has $900,000 of guaranteed-cost premium and spreads its losses across about 30 reportable claims a year. A carrier proposes a $250,000 per-claim deductible with a $1.5 million annual aggregate on deductible reimbursements.

• In a good year, 28 claims are small, and the total paid inside the deductible is $600,000. The company reimburses $600,000 and pays a much lower premium than $900,000.
• In a bad year, one back injury reaches $700,000 and several other claims total $900,000. The company reimburses $250,000 on the large claim plus the other claims, until the $1.5 million aggregate is hit, and the carrier pays the rest.
• At the renewal, the carrier increases collateral to cover development on the bad year, say by raising the letter of credit.

The decision turns on whether the company can absorb a $1.5 million bad year, whether the premium credit pays for the expected retained losses with margin, and whether a banker will issue the letter of credit without choking the revolver. The deductible and retention break-even calculator and Total cost of risk (TCOR) calculator help frame the trade.

Who should consider it, and who should not

Large deductible programs tend to fit employers with:

• Several hundred thousand dollars or more of annual comp premium, enough that expected retained losses are reasonably predictable.
• Three to five years of favorable, credible loss run history and a documented safety and return-to-work program.
• Audited financial statements and credit that a bank or surety will support.
• Management time to oversee claims, since the money now comes out of the employer's pocket on every claim.

They suit poorly an employer whose loss pattern is volatile, whose balance sheet is thin, or whose claims practices are weak. Moving to a large deductible without a strong claims program hands the first dollar of every bad outcome to the company. If you outgrow a large deductible, the next steps are full self-insurance, covered in self-insuring workers' comp: requirements and trade-offs, or a captive arrangement, covered in Is a captive right for your business?

Questions to put to the carrier

• What is the deductible per claim, and is there an aggregate? Do allocated expenses count inside the deductible?
• How and when are reimbursements billed, and what is the dispute process on a bill?
• How much collateral, in what form, and what is the release schedule as years close out?
• Who administers claims, who controls settlement and reserves, and what reporting do you get?
• What happens if the insurer or its administrator changes mid-program?
• Are premium taxes and assessments computed on the full or the net premium?

The state workers' comp agency or insurance department decides how a program must be filed. Rules vary, so use workers' comp and benefits requirements by state and check with your broker before signing.

Key takeaways

• The insurer pays comp claims first and bills you for the deductible layer, so the injured worker is protected even if you cannot reimburse.
• "Large" is not defined nationally. Florida requires at least $500,000 of premium and a $100,000 deductible for its filings (Rule 69O-189.006); other states set other lines.
• Collateral, not premium credit, is often the real cost. Negotiate its form, amount and release schedule up front.
• Losses below the deductible still flow into your experience mod through unit statistical reporting.
• Compare the program to guaranteed-cost coverage on a total-cost basis, including taxes, assessments, collateral costs and claims administration.
