Monopolistic workers’ comp states catch multi-state contractors off guard. A Texas contractor can carry a solid private workers’ compensation policy, send a crew to a pipeline job in North Dakota or a plant turnaround in Ohio, and discover that the policy does not respond there. In four states, workers’ comp is sold only through a state-run fund, and the rules for coverage, claims, and medical care are different from the rest of the country.
Most guides to monopolistic states are written by insurers and stop at how to buy coverage. This one also covers what happens after a worker gets hurt: how claims and medical care work in each state, and how to keep injury management consistent when your crews move across state lines.
What Makes a Workers’ Comp State Monopolistic
In most states, employers buy workers’ compensation from private insurers, a competitive state fund, or self-insure. In the four monopolistic states, Ohio, North Dakota, Washington, and Wyoming, employers that need coverage must get it from the state fund. Private carriers cannot write workers’ comp there.
| State | State fund | Self-insurance | Notable rule |
| Ohio | Ohio Bureau of Workers’ Compensation (BWC) | Allowed for qualifying employers | State-fund employers choose a managed care organization (MCO) to manage the medical side of claims |
| Washington | Department of Labor & Industries (L&I) | Allowed for certified employers | Care after the first visit must be with an L&I network provider |
| North Dakota | Workforce Safety & Insurance (WSI) | Not available | State fund is the only option |
| Wyoming | Workers’ Compensation Division | Not available | Coverage is mandatory for industries the statute defines as extrahazardous, including construction |
For Wyoming, the statute lists the extrahazardous industries where coverage is required; employers outside those industries may elect coverage. Confirm how your specific operations are classified before work begins.
The Coverage Gaps Multi-State Contractors Hit
1. Your private policy stops at the border
A standard private policy’s other-states coverage does not extend to monopolistic states. A crew working in one of the four typically needs coverage from that state’s fund, set up before mobilization. Some states have rules or agreements covering short-term out-of-state work, so the answer
depends on the state, the length of the job, and where the workers are based. Get a written answer from your broker and the state fund, not an assumption.
2. Employer’s liability is not included
Monopolistic funds do not include employer’s liability coverage, which protects the employer against certain injury-related lawsuits, such as third-party-over actions. Stop-gap coverage, usually added as an endorsement to a general liability policy, fills that gap. Contractors who assume their workers’ comp program covers it can be exposed.
3. Subcontractor coverage is harder to verify
Certificates of insurance from private carriers do not prove coverage in a monopolistic state. For crews and subcontractors working there, verify state-fund account status directly. Our guide for Texas general contractors covers subcontractor coverage verification in more detail.
How Injury Care Works Differently in Monopolistic States
Coverage is only half the problem. Each state fund also sets rules for how injured workers are treated and how claims are managed, and those rules decide how fast a worker gets appropriate care and returns to work.
| State | What your supervisors and case managers need to know |
| Washington | L&I covers the first office or emergency room visit even outside its network, but continued care must be with a provider in L&I’s Medical Provider Network. Plan the first visit so follow-up care stays in network. |
| Ohio | State-fund employers select an MCO, which helps manage the medical portion of each claim. Choosing and working actively with your MCO affects reporting speed, treatment approvals, and return-to-work planning. |
| North Dakota and Wyoming | Claims run through the state fund. Know the fund’s reporting steps and forms before the job starts, and identify nearby clinics that treat workers’ comp patients in each work area. |
Across all four states, the principles that control claim cost are the same ones that apply everywhere: report the same day, get occupational medicine triage in the first hour, write specific work restrictions, and offer modified duty. We cover those levers in how to reduce workers’ comp costs in construction.
Emergencies come first None of these network or claim rules apply to emergency care. A worker with a serious injury goes to the nearest emergency department, in any state, and the claim steps follow
A Pre-Mobilization Checklist for Crews Entering a Monopolistic State
1. Confirm coverage in writing with your broker and the state fund before the first worker arrives.
2. Add stop-gap coverage if employer’s liability is not already in place for that state.
3. Verify subcontractor state-fund status directly, not by certificate alone.
4. Map medical resources near each work site: emergency departments, occupational clinics that accept that state’s workers’ comp, and, in Washington, network providers.
5. Set the injury protocol so supervisors know who to call, where to send workers, and how to report under that state’s rules.
6. Assign case management so every claim has an owner who knows the state’s process and keeps return-to-work moving.
Keeping Injury Management Consistent Across State Lines
The real risk for multi-state contractors is not any one state’s rules. It is fragmentation: a different clinic, a different set of restrictions, and a different claims process on every job. That is where claim duration and cost drift upward.
A single physician-led program solves that. One medical director sets the triage and restriction standards, case managers coordinate care within each state’s network rules, and reporting comes back to your safety team in one format. We explain how that model works for multi-site employers in medical direction for multi-site and multi-state workforces.
How Occucare Supports Multi-State Contractors
Occucare International gives contractors one injury management standard wherever their crews work. Board-certified occupational medicine physicians provide occupational medical oversight and triage, our case management team coordinates care within each state’s rules and keeps return-to-work on track, and our network of 3,000+ vetted clinics gives crews access to occupational care near remote job sites.
From our Houston headquarters, we support construction and oil and gas employers with operations across Texas, other states, and internationally. Learn more about our workers’ compensation injury management.
Frequently Asked Questions
What are the monopolistic workers’ comp states?
Ohio, North Dakota, Washington, and Wyoming. In these four states, employers that need workers’ compensation coverage must obtain it from the state-run fund rather than a private insurance carrier, unless they qualify to self-insure where the state allows it.
Does my private workers’ comp policy cover crews working in a monopolistic state?
Generally not. The other-states coverage in a standard private policy does not extend to monopolistic states, so contractors sending crews there typically need to register with that state’s fund before work starts. Some states have rules or agreements for temporary out-of-state work, so confirm the requirements with your broker and the state fund before mobilizing.
What is stop-gap coverage?
Monopolistic state funds do not include employer’s liability coverage, which protects the employer against certain lawsuits related to employee injuries. Stop-gap coverage fills that gap, usually as an endorsement to a general liability policy.
Can injured workers in Washington see any doctor?
For the first visit, yes. Washington L&I covers the first office or emergency room visit when a claim is filed even if the provider is outside its network, but care after the first visit must be with a provider in L&I’s Medical Provider Network.
Who manages the medical side of an Ohio workers’ comp claim?
In Ohio, state-fund employers choose a managed care organization (MCO) from the Bureau of Workers’ Compensation’s list. The MCO helps manage the medical portion of each claim, so the employer’s choice of MCO shapes how quickly injuries are reported, treated, and returned to work.
Mobilizing Crews to Another State?
Occucare will help you map medical resources, set an injury protocol that fits each state’s rules, and manage every claim to the same standard. Request a multi-state injury management consultation.
