Contact the County's Third Party Administrator
The County contracts with third party administrators to administer workers' compensation claims. Each workers' compensation claimant is assigned a claims examiner who determines the appropriate amount of benefits to be paid to each claimant. In addition, the claims examiner uses the claims administration system to issue benefit checks, which are sent to claimants.
If you have questions regarding your workers' compensation benefit checks, please contact your third party administrator below. If you do not know your claim number, then please call (213) 351-5479 and provide your employee number.
