What forms and pamphlets does the employer need to be aware of?
Effective October 8, 2010, all California employers are subject to the new workers’ compensation regulations addressing the posting of notice to employees (CCR9881-9881.1), written notice to new employees (CCR9880) and use of the new DWC-1 Claim Form/Notice of Potential Eligibility (CCR10139).

Posting of Notice to Employees (DWC-7): The posting notice (DWC-7- 1/16 Rev.) must be posted in English and Spanish at each California work site in a conspicuous location frequented by employees during the hours of the work day. Additionally, if an employer has implemented a Medical Provider Network (MPN), then the full MPN notification shall also be posted in both English and Spanish in close proximity to the posting notice (DWC-7). The DWC-7 Posting Notices can be found on our website at:

Written Notice to New Employees: Every employer shall provide to each new employee, either at the time of hire or by the end of the first pay period, a written notice concerning their rights, benefits and obligations under workers’ compensation law as outlined in CCR9880. The distribution must include a form that the employee may use as an optional method for notifying the employer of their choice to predesignate a “personal physician” per LC4600 and LC 4601. The California Division of Workers’ Compensation has published a new hire pamphlet that meets these requirements. It is called the “Time of Hire Notice” and is available in English and Spanish.

Copies of the Predesignation of Personal Physician form are available at

DWC-1 Claim Form/Notice of Potential Eligibility (CCR 10139): Employers must provide the revised DWC-1/Notice of Potential Eligibility form (1/16 Rev.) to the employee within one working day of receiving notice or knowledge of an injury resulting in lost time beyond the employee’s work shift at the time of injury or which results in medical treatment beyond first aid. Copies of the DWC-1 Claim Form/Notice of Potential Eligibility form are available at

Additionally, if an employer has implemented a Medical Provider Network (MPN), the complete written Employee MPN Notification must also be provided to the employee at the time of injury.

If you report the claim via the Internet or by telephone, you do not need to fill out this form. If you report the claim via fax, complete the form below, and fax it to Crum&Forster at the fax number provided above.

What is the Waiting Period For Lost Wages in California?
The waiting period is 3 days. If the employee is off work for more than 14 days, the first 3 days are paid retroactively.

What are the Choice of Physician Rules in California?
If the employee does not predesignate a physician (prior to a work-related injury), the employer/insurer direct the medical care by utilizing the Medical Provider Network (MPN). If properly implemented, the insured/carrier will retain medical control through the life of the claim.

Medical Provider Network: The Medical Provider Network (MPN) is a great tool for employers to reduce their claim costs. We have two MPN options to choose from as displayed in the MPN Comparison Chart below. Please contact your Claims Account Executive to discuss the implementation process.
