What Is Workers’ Compensation?
Workers’ compensation covers medical costs and lost wages when an employee is injured or becomes ill on the job. In exchange, employees generally give up the right to sue their employer over the injury, a trade-off that protects both sides.
For contractors specifically, it’s also one of the most heavily scrutinized coverages on a job: general contractors, developers, and public agencies routinely check it before you’re even allowed to bid.
Who Needs It?
In California, any business with one or more employees is generally required to carry workers’ compensation, with narrow exemptions for qualifying owners. Requirements vary by state. We’re licensed in California, Florida, Minnesota, Utah, and New Jersey, and can walk you through what applies where you operate.
- Employee-vs-1099 misclassification is one of the most common compliance issues we see with contractors.
- Subcontractor requirements often get overlooked until a certificate of insurance request exposes a gap.
Understanding Your X-Mod: The One Number That Quietly Controls Your Premium
Every contractor starts at a baseline of 1.00. Below that is a “credit mod”: your losses run better than average for your class of work, and you pay less. Above 1.00 is a “debit mod”: your losses run worse, and you pay more.
The formula splits every claim into a heavily-weighted “primary” portion and a lightly-weighted “excess” portion, which is why claim frequency moves your mod more than the size of any one claim. Three small soft-tissue claims will typically hurt your mod more than one unusually large one.

Common Contractor Mistakes
- No return-to-work or modified-duty program, so claims stay open, and reserved, longer than necessary.
- Ignoring open reserves, which count against your mod even before anything is paid out.
- Wrong class codes or payroll misallocation, which compares you to the wrong peer group.
- Never requesting an annual worksheet review, missing clerical errors that are otherwise correctable.
- Late claim reporting, which tends to inflate reserves and drag claims out.
How Unique Risk Helps
- Annual experience rating worksheet review, checking for coding errors before they cost you.
- EMR benchmarking against similar contractors in your trade.
- A personalized Workers’ Compensation Scorecard, a plain-English snapshot of where your program stands today.
- Claims advocacy on open files, especially attorney-represented or aging claims.
Frequently Asked Questions
How long do claims stay on my EMR?
Each claim typically factors into your mod for three consecutive rating years before rolling off, regardless of when it closes.
Can I appeal or correct my X-Mod?
Yes. If a claim was miscoded or the worksheet contains an error, your broker can request a correction from the rating bureau. This is routine, not a formal dispute.
What happens to my mod if I switch carriers?
It follows you, not the carrier. Your mod is calculated by the rating bureau from your claims history, independent of who underwrites the policy.
Does my X-Mod affect my General Liability premium?
No. It applies specifically to workers' compensation. That said, a poor safety record often shows up across other coverage lines too.
