Cross-State Workers Comp Mod: The Split Point No One Checks
A Georgia construction worker dies on an Alabama jobsite. The employer's mod impact hinges on which state's split point applies. Most multi-state contractors don't know the difference.
When construction crews cross state lines, each workers' comp claim enters the NCCI experience rating system using the split point of the state where the loss occurred. Split points now range from $9,500 to $38,000 across NCCI states (NCCI Experience Rating Plan, 2024). The same fatality claim produces materially different primary loss amounts, and therefore different mod impacts, depending on which state has jurisdiction over the loss.
On May 21, a 22-year-old construction worker from Albany, Georgia, was killed on a jobsite in Marshall County, Alabama. A passing pickup struck a cable wire he was holding from a bucket truck at elevation. He was airlifted. He didn't survive.
The employer's experience modification rate (EMR, also called "the mod") will carry this claim for three policy years. But for any contractor running cross-state workers comp operations, the mod impact isn't determined by claim size alone. It depends on which state's split point applies to the loss, and that answer changes every time a crew crosses a state line.
NCCI (the National Council on Compensation Insurance) manages experience rating for roughly 36 states and D.C. When an employer has payroll in two or more of those states, NCCI issues a single interstate mod that blends loss and payroll experience from all of them. Each claim in that calculation gets split into primary losses (full weight in the formula) and excess losses (reduced weight). The dividing line is the split point. Since late 2023, the split point is no longer the same everywhere.
How cross-state workers comp mod exposure shifts by state
Before November 2023, every NCCI state used the same $18,500 split point. A $500,000 fatality claim produced $18,500 in primary losses no matter where it happened. NCCI's 2024 overhaul replaced that uniform number with state-specific split points calibrated to each state's average lost-time claim severity (NCCI Experience Rating Methodology, 2024).
The range is stark. Oregon's split point sits at $9,500. Louisiana's is $38,000. Alabama's is $23,500 (NCCI, March 2024). For the Marshall County fatality, that means $23,500 of the claim loads at full weight in the mod formula, with the remaining balance discounted as excess. Had the same accident happened in a state with a $15,000 split point, $8,500 less would carry full weight. On a mid-size contractor's mod, that difference alone can move the result several points.
The jurisdiction question isn't always obvious
Most contractors assume their claims follow the policy's home state. They don't. Workers' comp jurisdiction generally follows the state where the injury occurred. A Georgia contractor dispatching a crew to Alabama has an Alabama claim if someone gets hurt on an Alabama jobsite.
That jurisdiction call determines more than the split point. It sets the benefit levels, the medical fee schedule, and whether the claim gets litigated under Alabama's workers' comp statute or Georgia's. For the Marshall County loss, everything flows through Alabama's system and Alabama's $23,500 split point, then into the employer's blended interstate mod.
The policy has to cover it, though. Part Three of the standard workers' comp policy (Item 3.C, "Other States Insurance") extends coverage to states not listed on the declarations page. It's designed for temporary and incidental exposures. Southeast construction contractors cross state lines constantly. A framing crew based in Dalton, Georgia, might work sites in Chattanooga one week and Huntsville the next. Part Three is what catches those exposures, with a 30-day notice requirement to the carrier once work begins.
If Part Three excludes a state, or if the employer is in the assigned risk market where Other States coverage is limited to incidental exposure only, a claim in an unlisted state can become uninsured. The premium savings from skipping that endorsement vanish the moment someone gets hurt across the line.
When the policy gap opens a tort door
A Maine Supreme Judicial Court decision from May 19 shows what happens when cross-state coverage has a structural hole. In Valmont-Olivier v. Envirovantage, Inc. (2026 ME 45), a Massachusetts temp worker was injured at a Portland, Maine, job site. He filed a workers' comp claim in Massachusetts through his staffing agency. Then he sued the host employer for negligence in Maine court.
The host employer argued tort immunity: workers' comp should be the exclusive remedy. The court disagreed. Because the staffing agency's policy lacked an Alternate Employer Endorsement naming the host company, the exclusive remedy shield didn't extend to them (Valmont-Olivier v. Envirovantage, 2026 ME 45, May 2026). The negligence case goes to trial. Damages are uncapped.
For construction contractors using staffing agencies or labor brokers across state lines, the lesson is direct. If the policy structure doesn't match the employment structure, a workers' comp claim can become a tort claim. Tort claims don't flow through the mod. They flow through a jury.
What an audit would check
An audit of a multi-state contractor's experience rating verifies whether each claim on the worksheet is coded to the correct state, whether the applied split point matches NCCI's current state-specific table, and whether the policy's Other States coverage actually extended to the state where each loss occurred. In our reviews of Southeast contractor worksheets, at least one claim with incorrect state coding or a misapplied split point is more common than most employers expect.
