Existing law establishes a workers' compensation system, administered by the Administrative Director of the Division of Workers' Compensation, to compensate an employee for injuries arising out of and in the course of their employment. Existing law requires an injured employee to file a claim form with the employer. Under existing law, except for specified injuries, if liability is not rejected within 90 days after the date the claim form is filed with the employer, the injury is presumed compensable and the presumption is rebuttable only by evidence discovered subsequent to the 90-day period. For certain injuries or illnesses, including hernia, heart trouble, pneumonia, or tuberculosis, among others, sustained in the course of employment of a specified member of law enforcement or a specified first responder, this bill would reduce those time periods to 75 days. The bill would make other conforming changes. Existing law prohibits aggregate disability payments for a single injury occurring on or after January 1, 2008, causing temporary disability from extending for more than 104 compensable weeks within a period of 5 years from the date of injury, except if an employee suffers from certain injuries or conditions. This bill would, for specified firefighters and peace officers claiming illness or injury related to cancer, increase the number of compensable weeks to 240 without limitation as to time from the date of injury. Existing law requires that certain proceedings, including proceedings for the enforcement against the employer or an insurer of any liability for compensation, be instituted before the Workers' Compensation Appeals Board. Existing law authorizes the appeals board to fix and determine, in its award, the total amount of compensation to be paid and specify the manner of payment, or may fix and determine the weekly disability payment to be made and order payment during the continuance of disability. Existing law requires that when payment of compensation has been unreasonably delayed or refused, either prior to or subsequent to the issuance of an award, the amount of the unreasonably delayed or refused payment be increased up to 25% or up to $10,000, whichever is less. Existing law requires the appeals board to use its discretion to accomplish a fair balance and substantial justice between the parties. This bill would require, if liability for an injury has been unreasonably rejected for specified claims of injury or illness, including hernia, heart trouble, pneumonia, or tuberculosis, among others, sustained in the course of employment of a specified member of law enforcement or a specified first responder, the amount of the penalty to be 5 times the amount of the benefits unreasonably delayed due to the rejection of liability. The bill would limit the penalty to no more than $50,000. The bill would require the appeals board to determine the question of whether the rejection of liability is reasonable. The bill would apply this provision to all injuries, without regard to whether the injury occurs before, on, or after the operative date of the bill. Existing law requires the Administrative Director of the Division of Workers' Compensation, among other duties, to develop a workers' compensation information system in consultation with the Insurance Commissioner and the Workers' Compensation Insurance Rating Bureau, with certain data to be collected electronically. This bill would require the division, upon an appropriation by the Legislature, to identify and amend its existing data collection processes to include collection of the date on which a claimant is notified of acceptance, denial, or conditional denial of liability.
