Not published by the payer
Workers compensation is not one payer: every state runs its own system, some through a state fund, some through private carriers and managed care networks. Provider participation ranges from state certification (for example Ohio's BWC provider certification) to joining carrier-contracted networks, and billing follows the state fee schedule.
The stall to avoid: Check three things per state before treating injured workers: whether the state requires provider certification or registration, which network the employer's carrier uses, and the state fee schedule. Treating outside the required network can make claims unpayable.

About Workers' Compensation
State-mandated insurance covering work-related injuries and illnesses. Each state has its own workers' compensation agency and fee schedules. Providers must register with the state workers' comp board/commission. No CAQH — enrollment is state-specific. Reimbursement follows state fee schedules (often based on Medicare RBRVS).

Workers' Compensation credentialing requirements by state
Workers' Compensation enrollment is not identical everywhere. The table below lists what actually differs across the 51 states Workers' Compensation operates in — network status, local plan names, portals and the state-specific conditions our credentialing team has recorded.
| State | Local plan | Network | Portal / phone | State-specific notes |
|---|---|---|---|---|
| Alaska | — | Open | — | Administering agency: Alaska Workers' Compensation Division. Provider must register with the state workers' compensation board/commission. State fee schedule applies. |
| Alabama | — | Open | — | Administering agency: Alabama Dept. of Labor, Workers' Compensation Division. Provider must register with the state workers' compensation board/commission. State fee schedule applies. |
| Arkansas | Arkansas Workers' Compensation Commission (AWCC) | Open |
Provider portal

|
Arkansas workers' compensation is a private-insurer market with no state enrollment of providers. The Arkansas Workers' Compensation Commission sets the Medical Fee Schedule (Medicare RBRVS with Arkansas conversion factors) and certifies Managed Care Organizations under Rule 33; providers join MCO networks by contract rather than by state application. An employer contracted with a certified MCO designates the employee's initial provider, so network participation is how a provider becomes a first-line treater. |
| Arizona | — | Open | — | Administering agency: Industrial Commission of Arizona. Provider must register with the state workers' compensation board/commission. State fee schedule applies. |
| California | California Workers' Comp (DWC / Medical Provider Network) | Open |
Provider portal
1-800-736-7401
|
California workers' compensation uses the Medical Provider Network (MPN) system: insurers and self-insured employers build MPNs approved by the Division of Workers' Compensation, and most injured workers must treat within their employer's MPN. Providers do not enroll with the state — they join by contracting with MPN applicants or network intermediaries (PPOs/HCOs) under Labor Code 4609, and the MPN credentials its listed providers. Reimbursement follows the Official Medical Fee Schedule (RBRVS methodology). To join, contact the MPNs directly to offer your services. |
| Colorado | — | Open | — | Administering agency: Colorado Division of Workers' Compensation. Provider must register with the state workers' compensation board/commission. State fee schedule applies. |
| Connecticut | — | Open | — | Administering agency: Connecticut Workers' Compensation Commission. Provider must register with the state workers' compensation board/commission. State fee schedule applies. |
| District Of Columbia | — | Open | — | Administering agency: DC Office of Workers' Compensation. Provider must register with the state workers' compensation board/commission. State fee schedule applies. |
| Delaware | Delaware Workers' Compensation (Office of Workers' Compensation) | Open |
Provider portal
1-302-761-8200
|
Delaware's workers' compensation is a private-insurer market with a state Certified Provider Program. Certification is technically optional, but a non-certified provider must preauthorize each procedure, office visit, or service with the carrier (except the employee's first visit) — certification removes that per-service preauthorization burden. Certification (19 Del. C. 2322D) requires a current license, valid DEA registration where applicable, malpractice coverage, no disqualifying exclusions, and completion of state-approved workers' comp continuing education every 2 years. Reimbursement follows Delaware's Health Care Payment System fee schedule; carriers must pay clean invoices within 30 days. |
| Florida | — | Open | — | Administering agency: Florida Division of Workers' Compensation. Provider must register with the state workers' compensation board/commission. State fee schedule applies. |

North Dakota is a monopolistic workers' compensation state: Workforce Safety & Insurance (WSI) is the sole insurer. Before receiving reimbursement, a practice must complete the WSI Medical Provider Payee Registration form (one per group/billing NPI). WSI publishes its own fee schedules covering in-state and out-of-state providers, and since July 2021 accepts medical bills almost exclusively via EDI through its clearinghouse (paper allowed only for very low-volume billers). |

|
Ohio is a monopolistic workers' compensation state: the Ohio Bureau of Workers' Compensation (BWC) is the sole insurer, and providers must be BWC-certified to participate in the Health Partnership Program and be reimbursed. Apply with the MEDCO-13 Provider Enrollment and Certification form; a non-certified track (MEDCO-13A) exists for limited/one-off reimbursement, and recertification uses the MEDCO-13B. BWC reviews applications against minimum licensing and accreditation criteria and publishes its own fee schedule. |

Wisconsin workers' compensation is an open private-insurer market with no provider registration, enrollment, or certification — any licensed Wisconsin provider may treat injured workers. Notably, Wisconsin has no workers' comp medical fee schedule; fee disputes are resolved by the Department of Workforce Development under a reasonableness standard using certified health-cost databases. The injured worker may select any licensed physician, psychologist, chiropractor, or podiatrist, with a second choice allowed. Provider obligations center on medical reporting and dispute participation. |

Common questions about Workers' Compensation credentialing
How long does Workers' Compensation credentialing take?
Workers' Compensation credentialing typically takes 14–60 days from a complete submission to an approved effective date. Incomplete applications are the main cause of delay: a missing document or an unattested CAQH profile restarts the clock rather than pausing it.
Does Workers' Compensation require CAQH?
No. Workers' Compensation does not enroll through CAQH ProView, so credentialing data is submitted directly on Workers' Compensation's own application instead. You still need the same underlying documents — license, DEA where applicable, malpractice coverage and work history.
Which states does Workers' Compensation operate in?
Workers' Compensation has credentialing operations in 51 states. 51 of those 51 currently show an open panel. Requirements are not uniform: local plan names, provider portals and state-specific conditions differ, which is what the state-by-state table above records.
